Effect of long-term use of inorganic fertilizers, organic manures and their combination on micronutrient uptake under rice-rice cropping system

N Goutami, Ch Sujani Rao

A field experiment entitled “Carbon sequestration and soil health under long term soil fertility management in rice-rice cropping system" was carried out under field conditions during 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 results indicated that micronutrient uptake highest (except zinc) was observed with application of 100% RDF + ZnSO4 +FYM (T7). However, it was on par with application of only application of 10t/ha FYM, 50% NPK + 50% N through FYM and 50% NPK + 25% N through FYM + 25% N through green manures. The zinc uptake was higher in application of 100% RDF + ZnSO4 +FYM @ 5 t ha-1 (T7) which was on par with application of 100% RDF along with ZnSO4 @ 40 kg ha-1.
