Long Term Effect of Different Nutrient Management Practices on Micro Nutrient Uptake under Rice-Rice Cropping System

A field experiment entitled “Long term effect of different nutrient management practices on micro nutrient uptake under rice-rice cropping system" was conducted under field conditions during both kharif and rabi seasons of 2016-2017 and 2017- 2018 at Andhra Pradesh Rice Research Institute and Regional Agricultural Research Station, Maruteru, West Godavari district in the ongoing All India Coordinated Research Project on Long Term Fertilizer Experiment Project. The findings demonstrate that the data regarding influence of long-term use of inorganics, organics and their combination on micronutrient uptake at different growth stages in kharif and rabi during both the years of the study revealed that there was increase significantly with application of 100% RDF in combination with ZnSO4 and FYM @ 5t ha-1. It was on par with that of application of 100 % RDF along with ZnSO4 @ 40 kg ha-1 and significantly superior over other treatments. The application of 50 % NPK + 50 % N through FYM was on par with 100 % RDF. Application of 100 % RDF along with ZnSO4 @ 40 kg ha-1 and application of 100 % NPK though not differ significantly and on par with each other during four seasons of study.
