Abstract: A field experiment was conducted at Crop research Farm Nawabganj CSAU&T, Kanpur (U.P.), during Kharif season 2016-17 to study the integrated use of organic manures and inorganic fertilizers in rice cv. NDR-359. The 9 treatments consisted of T1:Control, T2: 100% RDF(120:60:60), T3: 70% RDF+30% N as FYM, T4: 70% RDF+30% N as VC,T5: 70% RDF+30% N as PM, T6: 70% RDF+15% N as FYM+15% N as VC, T7: 70% RDF+15% N as VC+15% N as PM, T8: 70% RDF+15% N as FYM+15% N as PM and T9: 70% RDF+10% N as FYM+10% N as PM+10% N as 10% N as VC. The grain and straw yields increased with integration of Poultry manure + Vermicompost treatment i.e. 70% RDF + 15% VC+ 15% PM, 50.90q ha-1 and 61.08q ha-1, respectively computed 85.77% and 80.28% higher than control. The content of all nutrients increased with integration of FYM, VC and PM in comparison to control. It was observed that the number of tillers hill-1, plant height and 1000 grain weight increased with integration of inorganic fertilizers and FYM, VC and PM. The total uptake of N, P and K significantly increased with the application of inorganic fertilizers with FYM, VC and PM. These nutrients were also brought significant improvement in protein content in grain and straw. The highest protein content 8.44% was obtained with treatment combination of 70% RDF + 15% VC +15% PM and lowest in control (6.81%). The treatment combination 70% RDF + 15% VC +15% PM came out to be the best dose for most of the characters of the rice crop under study.
