Abstract

Experiments were conducted during Kharif and Rabi seasons of 2015-16 and 2016-17 in farmers fields to study the effect of different agronomic management practices on yield and net returns of rice-rice cropping system in 2 different mandals of Srikakulam district of Andhra Pradesh. The results revealed that yields of rice-rice cropping system were significantly higher over farmer's practices, by adoption of all the recommended package of practices which includes maintenance of optimum plant population and application of recommended dose of NPK and zinc fertilizers at right stages of the crop growth to both the crops in the cropping system.
