Factors Affecting Molybdenum Uptake Of Soybeans And Yield Response With Varying Molybdenum Content Of The Seed

This investigation reconfirme the important role of molybdenum in the growth of the soybean plant. The greatest need of this micronutrient seems to be in the acid soils of north Georgia which fact had previously been reported by other workers. Large variations in yield were obtained, especially in the north Georgia area; however, no extreme high yields were produced with any treatment at any location. Obtaining a high yield per acre was not the primary objective of this study. The seed was selected on the basis of molybdenum content of the seed and not on previous yield performance records. It was also necessary to select a variety would mature in all sections of the state. Weather conditions reduced the yield of beans in 1965 and 1966 at the Athens location. The prolonged drought during the blooming stage was primarily responsible for this reduction. There were no other production problems during the testing period. This information could be very beneficial to soybean production in the state. The data show that sufficient amounts of molybdenum can be stored in the seed to meet the needs of plant. Whit a small amount of effort soybean seed growers could produce a seed which would not require additional amounts of molybdenum for high production. This could eliminate the time and trouble in applying the one ounce recommended rate of molybdenum as a seed treatment and eliminate the problems of poor application of the molybdenum material. From these data obtained in 1964, 1965 and 1966 on the various rates of ...
