TOP farmer ROUNDTABLE If you had a chance to sit down with some of the coun try's leading agricultural au thorities and ask them for their comments concerning your farming operation, what would you like to know? These farmers had that chance. Read what they asked and what the specialists had to say. Perhaps some of their comments will apply to you. FROM SIDNEY LEGG, WINDFALL, INDIANA: “/ farm 330 acres in partner ship with my mother. Since 1937, the main business on this farm has been the production of certified farm seeds. In addition we now feed out 200 to 300 head of feeder pigs a year and we maintain a small beef breeding herd (10 to 15 cows) to clean up waste land and crop residues. “Indiana soybean fields were very weedy in 1961. We need a pre-emergence herbicide to kill both grassy and broadleaf weeds. Is there an answer?" BURGER: "While there is no substitute for proper preparation and timely cultivation to control weeds in soybeans, weeds do become firmly established, es pecially if rainy weather pre vents especially good cultiva tion. Three pre - emergence herbicides, namely, Alanap, Randox, and Cl PC, have been approved by the Federal Drug Administration for weed con trol in commercial soybeans. Where grasses are the major problem, Randox, which is specific tor annual grass weeds, may be used. Since Randox is seldom injurious to the germinating soybean and both CIPC and Alanap may be deleterious to soybean stands, farmers will readily use Ran dox. Both annual grasses and nearly all broadleaved weeds are controlled by Alanap. Al anap rarely controls annual smartweed, which is fairly common in soybean fields. A combination of Alanap and CIPC is used in some states to control the annual grasses and the broadleaved weeds, in cluding annual smartweed, even though there is risk of getting injury to germinating soybeans. For the proper func tion of these pre-emergence chemicals, the active kilting agent must be carried into the soil profile, where the weed seedlings germinate, but not so deep that the germinating soybeans are primarily affect ed. It is fortunate, therefore, that the kind of weather that prevents timely cultivation is also the type which is needed 1 for effective weed control by pre-emergence chemicoii. "Preliminary test* using Amiben have shown promise. However, this chemical has been approved for use on soy beans grown for seed only." FROM ROBERT STOOPS, TIPTON, INDIANA “I farm 355 family owned acres of prime land in one of the best corn counties of In diana—except for one 40 acres located quite a ways from the home farm which is tenant-op erated. We emphasize hogs in our livestock program but feed steers when we are satisfied with the market outlook. In my crop ping program, I still like a rota tion with corn, soybeans, wheat and clover. It seems to reduce my fertilizer—and still keep my yields well above 100 bushels per acre. MF » I « I/I JC l/Ci U( J Cl*l J M/C IMII/C trie*/ to follow a sound rotation policy and produce according to demands for our products. We maintain about 30 per cent of our acreage in corn, 40 per cent in soybeans and small grains, 30 per cent in rotation pasture. In the past this has giv en us satisfactory returns on investment and labor. However, in face of what looks like a move to increased control of produc tion and marketing by govern ment, should we go all out in production of grain crops in order to have sufficient base so there will be some choice left in trying to farm on a sound eco nomic basis? “Improved seeds and more productive cropping techniques keep building up the mountain of surplus grains. Yet govern ment agencies and agricultural colleges continue to put major emphasis on production in re search programs. Isn't it high time to divert the biggest share of this effort into research on how to utilize what we are al ready producing? What prog ress is being made in utilization research?” KUT1SH: "Your best alternative to day is the same as it always is — to produce as much corn as your farm can sustain over the long pull. This is your an swer as an individual produc er. As a member of the farm ing profession, you are inter ested in seeing the production balanced with the demand ... but you can do this only as a member of the profession and in conjunction with others, not as an individual. Sound farm management tells you to get the highest sustained crop in come possible from your farm. "The progress in utilization research is not promising. Nothing on the horizon at present indicates that chem urgy offers any hope of solv ing the surplus problem in the next 5 years. Some increased use of food is possible through the Food for Peace program where food is used as an item of capital development in less well developed countries of the world. "The point is this — our yields have beef) going up faster than our needs; our out put per man has been going up faster than our needs. If we are going to continue to de velop and adopt these output increasing innovations, we just don't need as many acres or men in crop farming as we have had in the past. "But on prime land like yours, the only sound alterna tive for you as an individual is to crop it to give the highest income. If later some adjust ment program calls for an equal reduction by all produc ers, you should start to reduce from your optimum level of production, not some lesser level." FROM BERNARD CAMPION JOHNSON COUNTY, IOWA “/ feed out 300 head of cattle and raise 700 to 800 hogs per year. / use both high moisture shelled corn from a silo and mature ear com. From a nutri tion standpoint, what is the dif ference in feeding value between the two?” MORRISON: "Actually there is little nu tritional difference in the dry matter contained in high mois ture shelled corn and the grain part of mature ear corn, for either hogs or beef cattle. However, it must be realized that the high moisture shelled corn will contain about 25 to 30% moisture whereas grain from mature ear corn will contain about 16-20% moisture as commonly fed on the farm. Thus, it is often ne cessary for the animals to con sume more of the high mois ture corn. "On the other hand, high moisture corn seems to be more palatable to animals particularly hogs and especi nllw fAu/nr^c iUa a aI iUa feeding season when farm stored crib corn dries out to moisture levels of between 12 16%. It is also logical to sus pect that high moisture corn will contain a higher vitamin "So far, the experimental results with beef cattle with respect to high moisture corn feeding have been somewhat variable, but in general we can state that rates of gain and efficiency of feed use by cattle fed dry or ensiled high moisture corn are quite simi lar. When shelled grains are used, those cattle on high moisture corn will usually eat enough more high moisture corn to compensate for the less dry matter in the corn. "Now, as far as the direct comparison of dry mature ear corn and high moisture shelled corn is concerned, the daily gain of cattle on the high mois ture shelled corn will be slight ly better than those cattle on dry mature ear corn, simply because they will be consum ing more total digestible nu trients in their feed. Under normal conditions we might expect about 0.2 lb. daily gain less for the cattle on the ear corn. It should be pointed out that if a farmer is using high moisture corn storage he should always grind the grain or ear corn, either at the time of filling or else at time of feeding for the best results. "For pigs, average daily gains of growing - finishing pigs are quite similar when fed either high moisture or dry shelled corn. Although variable results have been ob tained, it generally takes somewhat more feed per hun dred pounds of gain with en siled shelled corn than with dry shelled corn.
