Effect of integrated nutrient management on crop nutrient uptake and yield under okra-pea-tomato cropping system in a Mollisol

摘要

Field experiments were conducted to find out the effects of integrated nutrient management on crop nutrient uptake and yield under okra-pea-tomato cropping sequence. The treatments were applied in the first crop and their effect was observed on instant as well as succeeding crops. Integrated use of organic and inorganic sources of nutrients and biofertilizers increased nitrogen, phosphorus and potassium concentration in the plants (including fruits) of okra, pea as well as tomato. Integrated nutrientmanagement also significantly increased shoot dry matter yield of tomato and fruit yield of okra and tomato.
