E C 15 1953 NORTH HFORIDA EXPERIMENT STATION Quincy, Florida December 9, 1953 NFES-Mimeo Report 54-2 SOYBEA :11. ').ENDATIONS FOR NORTH FLORIDA FOR 1954 by Thomas E. Webb Assistant in Agronomy Adapted Varieties.-The varieties recommended for North Florida are Jackson, Roanoke, Dortchsoy 31, and Ogden. The Jackson variety is well adapted to a wide range of soils and is recom- mended for planting in any of the North Florida counties on soils suitable for corn or other grains. Jackson is 4 to 6 inches taller than Roanoke or Dortchsoy 31. These three varieties mature about October 20, Jackson holds its seed well and its added height makes it more desirable for late planting such as behind oats or lupine. O&Fden matures early, about October 1, but must be combined within two weeks after maturity to avoid excessive shattering. All produce good seed yields and have high oil content. Date of Planting.-Soybeans planted May 15 to June 15 yield higher and pro- duce a better plant size for combining. Soybeans may be planted from May 1 to July 1. Still earlier or later plantings yield low and do not have sufficient height for combining. Date of planting has little effect on maturity date. Forty days' difference in planting dates delays maturity only 4 days. Soile.--Soybeans will grow in most soil types found in North Florida except eand. Yields depend upon fertility of these soils. Land Preparation.--o, beans require a good seed bed. Where soybeans follow oats, the straw must be r, uoved. Baling the straw for bedding and feed is the most popular method of rz'noval. If it is not convenient to bale this straw, then burning is recommended. Fertil;fer.--The use of 400 to 500 pounds per acre of 0-12-12 or similar analysis on good soils or following & legume crop ti recommended,. or poorer soils 500 pounds of 4-10-7 or similar analysis is recommended. No fertilizer is needed when soybeans follow a highly fertilized crop such as Irish potatoes, cabbage, sweet corn or other early spring vegetables. One ton of lime is profit- able on most soils. The fertilizer can be applied before planting with a spreader, at planting time in bands 3 to 4 inches on each side of the seed, or as a sidedressing at the first plowing. BE SURE THAT FERTILIZER DOES NOT TOUCH THE SVED. Row Width.--Thirty- to 36-inch rows are the most economical to use. This gives quicker ground cover for weed control, higher seed yields, and better use of equipment. -2- Rate of Plantin,-..Plant 1 to 1* bushels of seed per acre. A thick stand makes the beans easier to cultivate and gives a quicker ground cover for weed control. Depth of Planting.--Cover the seed one inch deep. Plant only when there is plenty of moisture for quick emergence. Plant beans on the level or slightly below. Cultivating.--Use rotary hoe or weeder as soon as beans first come up. Cultivate beans when they are 2 inches high. Plow flat or ridge beans slightly with about three cultivations. Havesting and Stor..e.- -The combine will do a good job of harvesting soybeans, if the machine is properly adjusted and the soybeans are low in moisture. Harvest- ing should begin when so;cboans contain about 12% moisture unless drier it to be used. Harvesting losses are often overlooked. For every 36 to 40 seed per square yard on the ground there is a harvesting loss of one bushel per acre. Cutting high enough to leave 5 to 6 pods per foot of row means a loss of one bushel per acre. Store beans at 12% moisture or less, Insect Control.--Several insects attack soybeans and their control is neces- sary for top yields. Insecticide dusts, which may be applied by tractor, airplane, or hand dusters are as follows: Insect Fall army worm Velvetbean caterpillar Mexican bean beetle Grasshopper Stink bud Insecticide Toxaphene, 10% Aldrin, 2% DDT, 1016 Same as above Toxaphene, 10% Toxaphene, 10% Aldrin, 24 Parathion, 1% Lindane, 2% Dosage 20 lbs. per acre 20 lbs. per acre 20 lbs. per acre Same as above 20 lbs. per acre 20 lbs. per acre 20 lbs. per acre 20 lbs. per acre 20 lbs. per acre |
