INTEGRATED NUTRIENT MANAGEMENT IN VEGETABLES- SUCCESS STORIES


With the objective of improving productivity, sustaining yield and soil health, farmer level demonstration trials were initiated in 2014 in different districts. One of the treatments in these trials was soil test based integrated nutrient management system combining lime, organic manures, bio fertilizers and inorganic fertilizers which was compared with the farmer level practices to highlight the benefits accrued. Trials were carried out in farmers fields with paddy, tapioca, banana, and vegetables. The results clearly indicated the superiority of soil test based integrated nutrient management with organics and bio fertilizer, bringing about a positive influence in economic benefits
Transfer of integrated nutrient management technology needs validation in the farm level. The Department of Agriculture in collaboration with the National Institute of Plant Health Management, Hyderabad, is conducting a Post Graduate Diploma Programme on Plant Health for Agricultural Officers of the State. Conduct of field trials on soil and plant health management is part of the curriculum.
Under this programme, multi-locational field trials on various crops have been undertaken and results are encouraging. Many farmers are now adopting this technology for improving crop productivity and sustaining soil health.

The success stories detailed below are projections from experiments conducted in different districts by the Agricultural Officers in small plots of farmer’s fields. The results are indicative of the positive effect of soil test based integrated nutrient management. However, when extended to larger areas the increase in yields/benefits accrued may not be same as the projections and slight variations in results are expected.

A few success stories on various crops are presented
