PERFORMANCE OF INORGANIC FERTILIZERS ON THE GROWTH AND NUTRIENT CONTENT OF SOYBEAN GENOTYPES

Soybean genotypes show diverse physiological responses to chemical fertilizers to evaluate the effects of different levels of chemical fertilizers (nitrogen, phosphorus, potassium, sulphur and boron) on growth and nutrient content of some selected soybean (Glycine max) genotypes (BARI Soybean 6, BD 2329, BD 2331 and BD 2340). In this experiment, physiological traits of soybean genotypes under different fertilizer doses in the field was investigated. A preliminary study with four soybean genotypes, one genotype (BARI Soybean 6)showed considerable better result than others. Besides this, the results also indicated that high dose of fertilizers had remarkable effect on plant height, number of leaves, dry weights of leaf, stem and petiole. Based on the findings, it was found that 100% of BARC recommended fertilizer proved to be most appropriate doses of nitrogen, phosphorus, potassium, sulphur and boron fertilizers for obtaining high yield in the soybean genotype BD 2329.
