Effect of various nutrients on yield uptake crop quality of hybridrice : Impact of N, P, K, S, Zn and bio-fertilizer on yield, uptake and crop quality of hybrid rice

A field experiment was conducted on Pot culture house of Department of Soil Science and Agricultural Chemistry at Chandra Shekhar Azad University of Agriculture and Technology, Kanpur during the Kharif season 2017 "Impact of N, P, K, S, Zn and Bio-fertilizer on Yield, Uptake and Crop Quality of Hybrid Rice". In the present experiment 9 treatments T1 (Control), T2 (100% RDF), T3 (100% RDF+ S40),T4 (100% RDF+Zn5), T5 (100% RDF+ Azotobacter), T6(100% RDF + S40+Azotobacter ), T7 (100% RDF + Zn5+Azotobacter), T8 (100% RDF+ S40+ Zn5+Azotobacter ), T9 (125% RDF), were laid out in Randomized Block Design (RBD) with four replication. Hybrid rice variety PHB-71 was taken for study. The results revealed that the grain and straw yield of rice respond significantly with the different treatment combination. The highest grain and straw yield was obtained in treatment T8. Nutrient uptake of N, P, K, S and Zn by grain & straw is highest in treatment T8. The current research analyzing the effects of N, P, K, S, Zn and Azotobactor level on quality characteristics of hybrid rice showed that the starch content, protein content in grain and head rice recovery increase with increasing nutrient doses.
