Nutrient management practices for enhancing soybean (glycine max l.) production
Soybean (Glycine max L.), is the most important pulse crop in the world. Soybean is a very energy-rich grain legume containing 40 percent protein and 19 percent oil in the seeds. The magnitude ofsoybean yield losses due to nutrient deficiency also varies among the nutrients. Deficiencies of N, P, Fe...

| Summary: | Soybean (Glycine max L.), is the most important pulse crop in the world. Soybean is a very energy-rich grain legume containing 40 percent protein and 19 percent oil in the seeds. The magnitude ofsoybean yield losses due to nutrient deficiency also varies among the nutrients. Deficiencies of N, P, Fe, B and S nutrients may cause yield losses up to 10 %, 29-45 %, 22-90 %, 100 % and 16-30 %, respectively, in soybean depending on soil fertility, climate and plant factors. Soil salinity is one of the major limiting factors of soybean production in semiarid regions, and chloride salinity has a more depressive effect on yield than sulphate salinity. The goal of nutrient management is to maximize soybean productivity while minimizing environmental consequences. Balanced and timely nutrient management practices applied forsoybean contributesto sustainable growth of yield and quality, influences plant health and reduces environmental risks. Balanced nutrition with mineral fertilizers can assist in integrated pest management to reduce damage from infestations of pests and diseases and save inputs required to control them. Balanced fertilization generates higher profits for the farmers, not necessarily through reduced inputs. The role of education and extension in delivering the upto-date knowledge on nutrient management is crucial, challenging, and continuous. |
