r NORTH FLORIDA EXPERIMENT STATION Quincy, Florida July 2, 1957 NFES Mimeo Report 57-12 SOYBEAN RECOMMENDATIONS FOR NORTH FLORIDA FOR 1957 by Thomas E. Webb Assistant Agronomist Adapted Varieties.--The varieties recommended for North Florida are Jackson, Lee,Roanoke, Dortchsoy 31, and Ogden. The Jackson variety is well adapted to a wide range of soils and is recommended 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, lee and Ogden mature early, about October 1 to 8. Lee is non-shatter but Ogden 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 produce 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. Soils.--Soybeans will grow in most soil types found in North Florida except sand. Yields depend upon fertility of these soils. Land Preparation.--Soybeans require a well prepared seed bed. Fertilizer.--The use of 400 to 500 pounds per acre of 0-12-12 or similar analysis on good soils or following a legume crop is recommended. For poorer soils 500 pounds of 4-10-7 or similar analysis is required. 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 profitable 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 SEED 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. 4A./iY 195-)^, "*^ARY^ Mimeo Rpt. 56-12 conttd. Rate of Planting.--Plant 1 to li 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 Plantin.--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. from the nitrogen Inoculation.--Soybeans, like other legumes, are able to utilize nitrogen air if properly inoculated. If soybeans are not inoculated, enough must be added to the fertilizer to make up the deficiency. 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. Harvesting and Storage.--The combine soybeans, if the machine is properly adjusted Harvesting should begin when soybeans contain Harvesting losses are often overlooked yard on the ground there is a harvesting loss high enough to leave 5 or 6 pods per foot of i acre, will do a good job of harvesting and the soybeans are low in moisture. about 12% moisture. -d. For every 36 to 40 seed per square of one bushel per acre. Cutting -ow means a loss of one bushel per Store beans at 12% moisture or less. Insect Control.--Several insects attack soybeans and their control is necessary for top yields. Insecticide dusts, which may be applied by tractor, airplane, or hand dusters are as follows Insect Fall army work Velvet bean caterpillar Mexican bean beetle Grasshopper Stink bug Dosage 10-15 Ibs. 10-15 Ibs. 10-15 lbs.
