Clinic experts unlock secrets to those... BOOMING BEAN YIELDS are to fix a maximum amount of nitrogen. If the seed you buy has not been inoculated, you can have it custom-treated or if you wish, treat the seed yourself using either a slurry or dry treatment. Plant at the best time. Early planting pays off with beans. Each three days' delay in planting can set maturity back one day. In the midwest, a two week delay may cut yields 9%. Use narrow rows. Growing soybeans in narrow rows has as much positive effect on boosting yields as growing corn in narrow rows, and perhaps more. Narrow rows cover the ground sooner and more thoroughly, reducing soil losses from rain and wind. Yield average of studies made in five midwestern states shows that medium- width rows of 21 to 28 inches outyielded wide rows by 15%. Provide adequate fertility. Though soybeans often don't respond to direct applications of fertilizer, top yields generally go with soils high in organic matter and of medium to high fertility. Because soybeans can get most of their nitrogen from the air, very little is needed from fertilizer. However, applying some nitrogen at planting time speeds the uptake of phosphorous. Supplemental nitrogen can be used, and a side-dressing of up to 30 Ibs. per acre has proved effective. Liming is likely to be profitable, too, if soil pH is not above 6.0. Or if your soil is very alkaline, you may need to add manganese. If your soil has a pH above 6.5, it is unlikely that you can produce 40 bushels of beans per acre without adding some manganese. Keep fields clean. You can do this either with chemical weed killers or intensive cultivation. A good selection of herbicides is now available. Broadcasting 3 Ibs. of Amiben per acre controls both annual grasses and broad-leaved weeds. If you have specific insect problems, the soil should be treated with insecticides. But, as representatives of Shell Chemical Company will point out at the Clinic, it is not necessary to treat soybeans for insects unless the bug problem is great and you know exactly what your problem is — otherwise insect treatment is not economical on soybeans. That's pretty honest, frank advice from a company which sells insecticides, but is the kind of straight-from-the-shoulder information you can expect to hear from Shell and other Clinic sponsors. YOU CAN WIN THE BUG BATTLE Insects have bugged crop growers for years, but modern insecticides are swatting out the problem. EACH YEAR, corn growers search for new ways to boost yields and cut production costs. How successful they've been at finding new corn growing tools is shown by progress made in the past ten years. During this time, average corn yields zoomed 57% and labor requirements plunged 47% — a 200% gain in bushels per man-hours per acre. This kind of progress wouldn't have been possible without modern soil insecticides. In short, they've wiped out the waste that early corn growers just accepted from insect-damaged plants. Even .the American Indians had a saying when they grew corn: "One for the bug, one for the crow, one to rot, and two to grow." Today's crop growers don't have to stand back and accept insect losses. They can make a blanket application .with a modern insecticide, and be fully assured that they'll get all the yield they have coming to them, no matter what kind of insects try to make pests of themselves. It doesn't pay to try to guess which soil insect might invade your corn. The odds are up to 20 bushels to 1 that you can't. Soil insects — more than 20 different kinds — work under ground where they can't be seen. And with all the different kinds threatening, some will be working no matter what the conditions. That's why today's top profit farmers apply a soil insect "insurance plan." The cost? Less than $3.00 per acre. The return? An average of an extra 10 bushels per acre. And, when soil insect damage is severe, it can mean a difference of 30 to 40 bushels an acre, or saving an entire crop which would otherwise be lost. Here's how per-acre cost of insecticide protection figures out: General soil insecticide recommendations call for 1 to 2 Ibs. of Aldrin per acre. That's $1.40 to $2.80 per acre for insecticide to protect a $60 to $70 per acre investment. If corn yields 100 bushels per acre without insecticide, and 110 bushels with insecticide, that's a 10% yield increase and a return of $10 per acre for each $1.40 to $2.80 invested in Aldrin. That's a healthy return on investment — and considering the many kinds of insects that can wipe out an entire crop — mighty cheap corn insect insurance. Assuming a 10 bushel increase in yield by using Aldrin, or ALDREX (a new combination granule of Aldrin and an organic phosphate which effectively controls all soil insects, including resistant rootworms), the chart below shows you can pay off equipment cost — plus insecticide cost — in one year and still have a profit left over. That's the reason profit-minded farmers don't gamble. Some corn growers just don't realize how much insect control can do for yields. Take, for example, the experiences of Harold Gardner, Cameron, Illinois: "I was doing everything else I knew how to boost yields, but I never really broke loose until I used an insecticide last year." Gardner used Aldrin to control cutworms and rootworms, and averaged a record-breaking 170 bushels of No. 2 corn on 870 acres, all of which was in narrow rows. This is the difference in stand on Dale Hood's Creston, la. farm in ALDREX treated rows as opposed to untreated rows. Insecticide makes as much or more sense than hail insurance to many farmers. Harry Broermann shows the difference in height of ALDREX treated corn as opposed to untreated corn on his Tarkio, Mo. farm. "I'd estimate that the Aldrin alone boosted my yields 30 bushels an acre. Given a choice between Aldrin and fertilizer on some of my land, I think I'd have to pick Aldrin." Gardner's experience confirms some of the data compiled by Shell Chemical Company, which shows that soil insecticides like Aldrin return 2 to 4 times their cost in extra income from higher yields on 9 out of 10 farms. Harry Broermann, Tarkio, Missouri, had a similar experience last year. The photo above shows the difference in height of his ALDREX treated corn as opposed to his untreated corn. It's interesting to note the weed growth in the untreated area of Broermann's corn, as compared to the treated area. Of course, ALDREX is not used for weed control, but the corn grew so vigorously in the ALDREX treated area, that the shade prevented weed seeds from germinating. Dale Hood, Creston, Iowa, found what was hurting his stands in the past when he applied ALDREX to his corn this year. In a strip he left for comparison, the stand was very spotty. But in his ALDREX treated rows, not a stalk was missing. When you think of the high investment of planting an acre of com, isn't it worth the low cost protection of Aldrin or ALDREX? Clinic speakers will spell out the obvious dollar and cents answer to that question.
