Nutrient Uptake by Fodder Soybeans Grown In Poultry-Manured Soil.

Field studies were conducted to evaluate eleven fodder soybean genotypes to explore their potential for the removal of nutrients from soils that had received heavy amounts of poultry manure. The experimental site had received heavy amounts of poultry manure in the previous years. The trials were also conducted on the soils without any poultry manure applications. The experiments were also repeated under green house conditions. Eleven soybean genotypes were included in the studies. The trials were conducted in randomized complete block designs with four replications. Each plot had four rows and each row was five meter long. The central two meter area of the central two rows was harvested when most of the genotypes were in early podding stages of their development. The dry plant samples were analyzed for nutrients uptake, especially phosphorous, after grinding. Soybean genotype 091734 and SE 737513 extracted significantly higher amounts of phosphorous in both crop growing seasons under field conditions and similar trend was found in the green house studies.
