Influence of integrated nutrient management practices on scented rice (Oryza sativa L.) pertaining to eastern Uttar Pradesh
A Field experiment was conducted to investigate the Influence of Integrated Nutrient Management Practices on Scented Rice (Oryza sativa L.) Pertaining to Eastern Uttar Pradesh at Narendra Deva University of Agriculture and Technology, Kumarganj, Faizabad (U.P.), during Kharif season of 2015-16. The experiment with seven treatments of integrated nutrient managements viz., T1: 50% recommended NPK + 50% N as FYM + 5 kg Zinc ha-1, T2: Recommended N each equivalent to 1/3rd of total N as FYM, vermicompost and neem cake, T3: 100% N as FYM + 5 kg Zn ha-1, T4: T2 + hand weeding + Neem based biopesticide, T5: 50% N as FYM + seedling treatment with Azotobactor and PSB, T6: T2 + seedling treatment with Azotobactor and PSB and T7: 100% NPK + 5 kg Zn ha-1, each treatment was replicated thrice in completely randomized block design. The results revealed that, T1 which was found at par with T3 and T7 while significantly superior over rest of the treatments. Yield attributes, grain yield (36.60 q ha-1) and straw yield (52.80 q ha-1) were found maximum under T1 which was at par with T3 and T7, significantly superior over rest of the treatments. The maximum gross return (` 108300.00 ha-1), net return (`71155.00 ha-1) and B: C (1.86) was recorded from the integrated (Fertilizer + FYM) treatment i.e. T1 for basmati rice. The minimum gross return (` 81600 ha-1) was recorded in the treatment received 100% nutrients through organic manures (50% N as FYM + Azotobacter + PSB) while the minimum net return (`31364 ha-1) and B: C ratio (0.61) in basmati rice were recorded in the treatment received 100% nutrients through organic manures.
