CHICAGO SEED CORN Do Ybvt KuoW "flmt It 'Will Grow ? p. G. Holder S/J-E-Waasoaier CORN AXIOMS 1. Not more acres of corn but more corn per acre by testing every ear, should be the motto of every corn grower. 2. We owe it to ourselves and to humanity to produce a maxi- mum crop. 3. No one has a right to plant an ear of seed corn without knowing it will grow. 4. Testing does not hurt the com. 5. It costs only a little work to test our com. 6. It can be done at a time when other labor is not pressing. 7. It is only good business to know what we are planting and we can find out only by testing each ear. 8. Weak and dead seed raeans a poor stand; a poor stand a poor crop. 9. To plant a dead or weak ear means about 900 missing, or weak, or barren stalks. 10. Missing hills and barren stalks mean wasted labor, wasted time, and wasted land. 11. The most precious thing in the world is the labor of a human being. Yet by not testing our seed com we waste hours every day on vacant ground and worthless stalks. 12. "Like tends to produce like." If we want good com we must plant good seed. 13. Planting "Just Corn" means harvesting "Just part of a crop." 14. We cannot afford to gamble that every ear will grow. Test and play safe. 15. In the corn belt, test between February 20 and March 20. 16. By testing we have everything to gain and nothing to lose. Test ^ Dont Gixess 5J3 l{) How to Test Seed Corn Or Easy Steps In Preparing Seed Corn, That Every Corn Grower Should Know And Follow The sawdust germination test is made on thousands of farms every season. Men are realizing that they cannot afford to plant an ear of corn without knowing that it will grow. The test is simple and can be put over by almost anyone. The steps outhned and the illustrations show how it is actually made. First — Arranging the Ears, Fig.l — Put them side by side on the table, planks, or anything that may be used for the purpose. They should now be carefully studied and compared and the weak and poorer ears discarded before any testing is done. Fii. 1. Second — Picking Out the Weak and Poorer Ears, Fig. 2 — Follow this step carefully. Time and work can be saved by discarding the poorer ears , before a germination test is made. Ask of each ear — Will it Yield, i. e.. Will it produce a profitable crop in my vicinity? Has it constitution, vigor and hardiness? Among the things that indi- cate good yield, are size, shape, solidity, weight of ear, depth of kernel, size of germ, well filled tip and butt, etc. Will it Ripen, i. e., WUl it mature, not only this year but every year on my farm? Lack of maturity will be shown by too large an ear, too deep a kernel, chaffiness, light weight, loose on the cob, and duU, starchy appearance. TEST EVMRY EAR Will it Grow, i, e. Is the kernel clear, bright smooth, and horny, with a large germ or heart? When the germ is dull, cheesy in appearance, or of a dark color, the ear should be thrown out. On the other hand, a white, brittle germ indicates strength. The test you are to mate will determine whether it wiU grow. Fit. 3. shape of both ear and kernel? Ears that are to be discarded should be carried to the feed bin or com crib immediately, thus avoiding any chance of getting them mixed with the seed corn by mistake. Fit. Does it Show Improvement, i. e.. From appearance does the ear show that there has been brains back of it — in other words years of careful selecting and breeding? Has it been selected long enough so that it will reproduce itself uniformly in type, in time of maturity, in size and aSE A GEItMIXAriOy BOX Third— Inspecting Each Ear, Fig. 3— The ears selected appear to be good ones — the next step is to inspect carefully every ear from the standpoint of the kernel. Take two or three kernels from each ear, about a third of the length of the ear from the butt; lay them germ side up at the tip end of the Fit. 4. ear from which they were taken. If the kernels are small, wedge shaped, narrow, too shalloWj too deep, or show immaturity, starchiness, tendency to mold, or if the germs are small, shriveled up, blistered, weak or frozen, the ear should be discarded. FiS. 5, Vii. 5V4. The work of throwing out the poor ears — those that from their ap- pearance are unfit for seed — has taken but a few minutes. How about the others? No one can tell definitely that they will grow. We simply have to test every ear in order to know. One can put over to test enough seed for thirty acres in a day. The following steps show how this is done. Fourth — Putting Over the Germination Test, Fig. 4 — The ears should now be laid out in rows and separated into divisions of ten ears each. It will not be necessary to number all the ears, but just those on the right of the nails, as follows: — 1, 11, 21, etc. SAWDUST BOX BEST Fifth — Preparing Sawdust, Fig. 5 — The sawdust should be put in a, gunny sack and soaked in warm water at least an hour, or better still, over nig'it. It should be well covered with water as shown in Fig. 532- AH saw- dust should be put in warm water just before putting it in the germination box. In most sections sawdust can be obtained from ice houses, saw mills, lumber yards, meat markets, or elsewhere.. Soak new sawdust over night in hot water. Sawdust Soaking Fi«^ 6. Sixth— Removing Excess Water, Fig. 6— This shows a method of remov- ing the excess of water in the sawdust. Too much water will make the saw- dust cold and soggy which will result in retarding the germination. Treading is a good way to remove the excess water. .i.7 Fit. 7Vi. Seventh — Preparing Germination Box, Fie 7— Fill th^ „„ box about half full of warm well-soaked sawdust, tnd pack it down™ and firm with a brick, leaving the surface even and smooth. " TESTING DOESN'T HURT THE COBN Fig. 7}^ — The germination cloth should now be put in the box and tacked in carefully around the edges. Notice that there is a margin of 2J^ inches around the edge of the germination cloth and that the squares are 2}/^ by 2}/^ inches. This box is large enough to test 100 ears of corn. The germination box should be 30 by 30 inches and four inches deep. Fii- 8. Eighth — Removing Kernels for Germination Box, Fig. 8 — Remove six kernels from six different places in ear No. 1, and place them in square No. 1 of the germination box. In removing kernels take two from near the butt on r-. lull] rLLlJ_Li, ^ ^1 «r) ^ dtf ^ f» * slai "»i .uit"*!** \ en. o. opposite sides of the ear, two from the middle, and two from the tip, tiirning the ear enough so as not to take two kernels out of the same row. Do the same thing with all the other ears until the germination box is full. 10 TEST SIX KERNELS FROM EACH EAR Ninth— Placing Kernels in Germination Box, Fig. 9— The kernels should be laid in the squares with the tips all one way, and the germ side up. A little care in doing this will assist materially in reading the tests later. Tenth— Laying on the Cover Cloth, Fig. 10 — As soon as the kernels are all carefully arranged, the germination test is ready for the cover cloth. Dip the cover cloth in warm water and wring it out before using. This cloth helps to keep the kernels in place and should always be used. Fi4. lO. Fiaii. Eleventh — Laying on the Top Cloth, Fig. 11 — The top cloth should be several inches larger than the germination box. Fit. 13 Twelfth— Packing Sawdust, Fig. 12— The box should now be filled with the warm sawdust and packed down carefully, as shown in illustration or packed down with a brick. The brick is usually preferable ' Thirteenth-Covering Tester, Fig. 13-This shows how the cloth should be folded m over the edges of the germination box. TE^T EARL Y WHEN OTHER WORK IS NOT PRESSING 11 Fourteenth — Raising Edge of Box, Fig. 14 — The edge of the box toward whifh the crowns of the kernels are pointed should be raised. If this is done, Fi«. 14. FiS. 141/4. the kernels, following the laws of nature, when germinating will send the stems out toward the upper part of the box and the roots will go downward. This will be a great help in reading the test. Tr Fii. 15. Fifteenth— Waiting for Corn to Germinate, Fig. 15— A good arrange- ment for leaving the corn until the germination test is ready to read. A board has been placed over the rows to keep the ears in place. It usually takes from seven to eight days for com to germinate well. When several tests are put 12 IN CORN BELT TEST DUBING FEBBUART OR MABCH over, the boxes may be piled on top of each other. The boxes should now be put away in an ordinary living room, cellar with furnace, or some other place where it does not freeze. Sixteenth— Removing the Cover Cloth, Fig. lo— Roll off the top cloth together with the sawdust. Fig. 163^— The cover cloth should now be removed carefully so as not to displace any of the kernels. When the sprouts are about two inches long it is time to read the te'its. FiA, 16. Fig. 16%. i Seventeenth — Reading the Test, Fig. 17 — Ears numbers 15, 18, 19, 20 land 61 have been pushed back out of line. The germination test showed that they were either weak or dead. The very weak and the dead ears should be immediately put in the feed bin. Those that show medium to strong Fit. 17. vitality and the slow ones should be put together, carefully labeled to prevent any mistakes in the future, to be used only in case there is a shortage of seed corn. They should be tested again if used for planting. DISCARD DEAD AND WEAK EARS 13 Thou shalt improve thy seed corn by selecting a hundred of the choicest ears, plant them together on the South or the West side of main field, from which to select seed for next year's planting. When reading test select the hundred best eais to use in the breeding plot. If the germination test of an ear is unusually good and the ear itself comes up to the standard set forth in the second step, it should be turned over with the tip end out as shown by ears numbers 11 and 12. The ears intended for the breeding plot should now be taken out and put together in one place and carefully labeled. The others are no'.v ready fop butting and tipping. VU. l7Vi. Fig. 173 2 — A section of a germination box. Ears 2, 11, 13 and 24 should be immediately removed and carried to the feed bin, for fear they might get mixed with the others by mistake. Ear 2 js weak. One kernel has not sprouted at aU, only swollen a little. Ear 11 shows one dead and one weak. Ear 13, six dead kernels. Ear 24, three dead kernels. Ears 21 and 23 are weak and slow and should be put to one side and not used unless absolutely necessary. Ears 1, 3, 4, 12, 14 and 22, show up strong and are now ready for butting and tipping. Ears like 2, which show some life, if planted wiU be behind all sum- mer and probably produce little or no grain. The plants will produce pollen and the tendency will be to reproduce its kind causing the corn to deteriorate instead of improving. 14 SHELL EACH EAR SEPARATELY Many experiments have been conducted showing that ears lilce 2 when planted alongside of ears that germinate like 22 would produce only about Fi«. 18. half as much corn. The results of thousands of tests made in Iowa show that there is often from 15 to 50 bushels less yield from weak seed than from the strong. There is absolutely no question but what testing pays. Test every ear. Don't guess. Fi«. 19. Eighteenth— Butting and Tipping, Fig. 18— After removing the weak' and dead ears and selectmg ears for the breeding plot, from which to obtain GRADE EACH EAR AFTER SHELLING 15 next year's seed corn, butt and tip the remaining ears. The round irregular kernels at the butt and tip will not plant well and evenly and for this reason should be shelled off. Nineteenth — Shelling the Corn, Fig. 19 — Each ear should be shelled by itself and carefully examined before it is mixed with the other seed com, i. e., are the kernels well shaped, carrying size well down to the tip, have they a clear, clean, cheerful color and a bright, healthy, horny appearance? If it does not come up to the standard it should be thrown in the discard. On the other hand, if the kernels are large and the qiiaUty is right, put them in the box marked "first grade — large size." If it is only second rate in quality, it should go as "large size — second grade." The small size kernels should be handled in the same way. Grade 1 should be planted first, and do not use the second grade unless absolutely necessary. Careful attention to grading each ear after it has been shelled will help materially in determining what plates to use in the planter to get a uniform, regular drop. Fi4. 20. Twentieth — Testing the Planter, Fig. 20 — After fifteen or eighteen ears have been shelled and graded, test the planter using different sized plates. If it is found that the grades selected do not fit the plates, shell some more corn and grade a httle differently, putting more of the corn in the large grade or the reverse. Now test the planter plates again and keep doing this until the grade conforms to the plates of the planter in such a way as to give the desired number of kernels per hill. This step should be taken before aU the corn is shelled, so that the work can be finished intelUgently. The proper amount of seed and its even distribution are important factors m producing the largest yields. In sections where the corn is mostly checked, and the crop is grown for the grains and not for fodder, greater attention should be given to uniform planting. It will not take more than an hour or two to test the planter, as described. It isn't good business to guess that the planter is dropping the right amount. Test the planter— know that the drop is right. Twenty-first— Removing ChafE and Grading, Fig. 21— Use about a half bushel of corn at a time, put it in a box and tread it for two or three minutes which will break off the sharp points and remove the chaff. It is 16 FIT THE CORN TO THE PLANTER best to remove the chaff, as it often gathers under the planter plates, inter- fering with the dropping of the planter. If the seed is picked immature, there is apt to be a sharp projection at the tip, which will interfere with the planter. Also more chaff is apt to cling to the kernel than if it were perfectly mature. The chaff should be removed for it wiU assist in getting a uniform stand. Fig. 21 j^ shows a method of using a small hand grader. This helps to take out the large, irregular kernels, which are always found on ears that are not perfectly poUinized. Running the corn through the hand grader takes but a few minutes and it will greatly reduce the work of removing bad kernels which is another important step in preparing corn for the planter. Twenty-second— Removing Bad Kernels, Fig. 22^upport a fanning miU screen on two barrels. Spread on it a' small quantity of corn, pick out all cracked, broken, irregular, moldy or rotten kernels. These will not Fi4. 21VS. drop well in the planter, or may take the place of good kernels, thus either leaving vacant spaces in the field or making weak stalks where there should be strong ones. As fast as the corn is sorted, scrape it dS into one of the barrels. On the ordinary farm this work may be done when the children are home to help. If you have never picked over your seed com, you will be surprised at the amount of imper- fect kernels found in a bushel. Don't neglect to pick over your seed corn this year. You have everything to gain and nothing to lose. Twenty-third— Caring for Seed Until Planting Time, Fig. 23— After the seed has been sorted, tested, shelled and graded for the planter, and bad kernels removed as described in the preceding steps, it should be sacked up, a half bushel in each sack, and hung up in a dry place where it will not freeze. A dry, weU-ventUated attic or basement with a furnace are good places for hanging the seed. Notice especially the white sacks on the left, bearing the label "Seed from the Best 100 Ears." It is a good plan to put the best seed in white sacks to Fie. 21. EEMO VE IRRE G ULAR, MOLD Y OR BO TTEN KERNEL S 17 distinguish them from the general supply of seed, which it will be noticed has been put in grain or gunny sacks. Fig. 22. When planting use the best seed first on one side of the field, from which to pick your seed corn for next year's planting. Knowing the certainty of Fit, 23. the law that "like produces like," it is evident that if this method of selecting a hundred of the best ears is followed that our corn will show improvement. 18 USE GOOD CLOTH IN GERMINATION BOX A Few of The Reasons Why We Should Test Our Corn 1st — ^By testing we can know what we are planting. 2nd — Testing cannot possibly hurt the corn. 3rd — It costs almost nothing, except a httle work. 4th — It can be done at a time when other farm work is not urgent. 5th — By testing, we have everything to gain and nothing to lose. Cautions in Testing The sawdust should be soaked in warm water until well saturated, or, if possible, over night. Be sure to use a good quality of sheeting for the test cloth (one to be marked off) and for the cover cloth. The" squares on the cloth should be 2J^ by 2J^ inches. Leave a 2J^ inch margin around the edge of the box; it wiU prevent drying out and give the outside kernels equal chance with the others. Notice Fig. 9. When removing the kernels be sure you do not get them mixed with kernels from another ear. Lay boards over the ears after the kernels have been removed. This will prevent them froin getting displaced or mixed up. Notice Fig. 15. Keep the germination box in a warm Mving room or warm basement with furnace where it will not freeze. Do not attempt to read the test before the stem sprouts are at least two inches long. Throw out all the ears the kernels of which are dead, show weak germina- tion, or moldiness. AH the cloths and the sawdust should be thoroughly scalded before making a second test. If used more than once without scalding they are apt to become sour and moldy, which will interfere with the test. Advantages of Sawdust Germination Box 1. It costs nothing but a httle time and labor. 2. It furnishes nearly natural or normal conditions. 3. The sawdust is light, clean and easy to get and handle in February and the first of March, when the testing should be done; is a good non-con- ductor of heat and cold, so that the temperature is kept even during germina- tion, and holds the moisture so perfectly that there is no danger of drying out. The number of boxes required will depend upon the amount of seed to be tested and the time Emit. When several boxes are used, stack them up one on top of the other. When the first set of boxes has been taken off, it is a good plan to put another set over at once, and while the com in these is sprouting, the first sets of ears can be butted and tipped, shelled, graded and hand-picked If more than one kernel of the six fail to grow, the ear should be discarded If only one kernel fails to grow, the ear should generally be discarded; unless it IS an especially good ear in other respects, when it might be well to eive it another trial in the next test. Ears whose kernels mold badly in the germination box should be dis- carded, it the kernels show weak, spindhng sprouts, or a part of them are very weak and uneven, the ear should be thrown out to make place for an ear whose kernels give strong, vigorous sprouts. Remember that the kernels which are slow to sprout and are weak will be behind the strong ones in the held, and being shaded by them will give weak, runty stalks with small ears Poor seed means a poor stand, with missing hills; one-stalk hills with weak stalks, producmg httle or nothing, also wasted land and wasted labor; it means less than thirty bushels of corn per acre in- stead of fifty or sixty; it means that we produce on an average in each hill just one small ear of corn weighing less than ten ounces.— From Corn Secrets. The Rag Doll Seed Corn Tester In some sections where it is difficult to obtain sawdust and in schools, the "rag doll" seed com tester may be used to advantage. It is so simple that any child can put over a test. First — Kind of Cloth — Use a good quality of bleached muslin. If a poor quality of cloth is used, the roots will grow through it and the test will be difficult to read. Second— Size of Rag Doll— The germination cloth should be 9 inches wide and 60 inches long. This will leave nearly 18 inches on each end for rolling. Third— Making the Rag Doll— Fig. 3 — Mark off the squares and num- ber them as shown in the illustration. The squares should be 2}/^ inches wide. Fourth — Making the Test — Fig. 4 — Lay out the corn to be tested on the table, as shown in steps 1, 2, 3 and 4 in making sawdust germination test. The cloth should be dipped in warm water and spread out as shown in illustration in preparing for the test. Fifth — Arranging the Kernels — Fig. 5 — Straighten out the kernels in the tester with their points all toward one side of cloth, and the germ side up. The tester should be put in a pail with the points of the kernels down. Sixth — Rolling Up Tester— Fig. 6 — After the squares have all been filled, roll up the tester, tie a string or put ,a rubber band around the center just tight enough to hold the kernels in place. Seventh — Putting Tester in Pail ■ — Fig. 7 — Put the testers now prepared in a pail or bucket. Be sure that the tips of the kernels are pointing down- ward. Do not pack too many rolls in a pail. Ten or twelve in a ten-quart paU are sufficient. If packed tight they wUl heat and sjjoU the test. Eighth— Wrapping Up Pail— Fig. 8 — The pail should now be filled with liike warm water, wrapped up carefully, and set away to soak for five or six hours. At the end of this time remove the wrappings and drain the water off. Lay a wet cloth over the top of the rolls, wrap the pail up again care- fully and set away for a couple of days.

Six Kernels None Too Many Seed Corn Commandments Thou Shalt test six kernels from every ear of corn intended for seed and discard the dead, weak and moldy ears. The six kernels should be taken from different parts of the ear, two near the butt on opposite sides, two at the center and two near the tip on opposite sides of the ear. The ear should be turned enough so that no two kernels are taken from the same row. The illustration shows that most of the dead kernels may be found on one part of the ear or they may be dis- tributed. This emphasizes the im- portance of taking kernels from as many different parts of the ear as possible. Sometimes the butt of the ear is dead because moisture has settled there and freezing has killed the 'germ. Oftentimes the under side of the ear wiU be entirely dead, all de- pending on how the ear was hanging on the stalk. Six kernels taken from six different places in the ear will be none too many to test the ear thoroughly. Ears partly dead should be dis- carded, for if planted they greatly re- duce the yield. 7267 tests made in Iowa of planting ears, which in the test showed one dead kernel, reduced the stand 8 per cent and the yield more than seven bushels per acre. In other words, figuring corn at fifty cents a bushel, that partly dead ear of corn cost the grower $3.50 by decreasing the yield. The ears showing weak germina- tion should be discarded because they will be fooling around all summer, will be late in maturing and many of them will not produce any grain at all. This is not all the harm they will do. Each stalk will produce pollen which will help to pollenize other ears of corn, thus tending to propagate the weak instead of the strong ears. If a kernel from a moldy ear happens to fall with kernels from good ears the mold will spread and kill them all. This is a result of many experiments conducted at Iowa State College. Thou Shalt shell each ear of corn separately, grade the corn and fit it to the planter so that it will drop the desired number of kernels regularly. By sheUing each ear separately they can be graded according to the size and quality of the kernel. The large kernels first grade should be put together, also the small kernels first grade should be kept separate from the rest and the second grade should be divided into large and small kernels. Divide the corn into grades according to the size of the plates so that the planter wiU drop the desired number of kernels the largest number of times possible. Thou Shalt improve thy seed corn by selecting a hundred of the choicest ears and planting them together on the south or the west side of the main field from which to select seed for next year's planting. There is no law more certain than that "like tends to produce like." If the largest and best ears are planted together from which to select seed for next year's planting, the tendency will be to improve the corn. £3 .rn KA •fitsan mm. na as m 5TR0W6- SWEA Courtesy of Iowa State College 1.

CORN THE BEST CROP FOR THE SILO Twelve Silo Reasons 1. More feed can be stored in a given space in the form of silage than in the form of fodder or hay. 2. There is a smaller loss of food material when a crop is made into silage, than when cured as fodder or hay. 3. Corn silage is a better feed than corn fodder. 4. An acre of corn can be placed in the silo at less cost than the same area can be husked and shredded. 5. Crops can be put in the silo during weather that could not be utilized in making hay or curing fodder. 6. More stock can be kept on a given area of land when silage is the basis of the ration. 7. There is less waste in feeding silage than in feeding fodder. Good silage properly fed is all consumed. 8. Silage is very palatable. 9. Silage, like other succulent feeds, has a beneficial effect upon the digestive organs. 10. Silage is the cheapest and best form in which a succulent feed can be provided for winter use. 1 1 . Silage can be used for supplementing pasture more eco- nomically than can soiling crops, because it requires less labor, and silage is more palatable. 12. Converting the corn crop into silage clears the land and leaves it ready for another crop. Date Due r«iV/..4'59T Library Bureau Cat. No. 1137
