Randomized trial evaluates integrated nutrient management for improving soybean and chickpea yields, suggesting profitable strategies.

The study aims to identify effective micronutrient management strategies to enhance soybean and chickpea productivity in rainfed Vertisols.
Conducted a three-year field experiment in Central India (2016-19).
Evaluated farmyard manure and micronutrient strategies (zinc and molybdenum) through different application methods.
Assessed both direct and residual effects on soybean and chickpea yields.
FYM at 5 t ha -1 increased soybean yield by 25.8% and improved chickpea yield by 19.2%.
Soil application of ZnSO 4 and ammonium molybdate resulted in the highest system productivity (4464 kg ha -1).
Integrated nutrient strategies increased net returns to ₹94,332 ha -1 and provided a protein capacity of 51 persons ha -1 year -1.

Jat et al. (2026) studied this question.
