Growth and yield of scented rice (Oryza sativa L.) as influenced by integrated nutrient management practices

摘要

Technology, Kumarganj, Faizabad (U. P.), India during kharif season of 2015-16 to evaluate the effect of different integrated nutrient management practices against organic and inorganic fertilizer treatments on growth and yield of scented rice. The experiment was conducted in randomized block design (RBD) with seven treatments of integrated nutrient managements viz., Tj-50% recommended NPK+50% N as FYM+5 kg zinc/ha, T2-Recommended N each equivalent to 1 /3rd of total N as FYM, vermicompost and neemcake, T3-100% N as FYM+5 kg Zn/ha, (T4) T2+hand weeding+Neem based biopesticide, T5-50% N as FYM+seed treatment with Azotobacter and PSB, T6-T2+grain treatment with Azotobacter and PSB and T7-100% NPK+5 kg Zn/ha, each treatment was replicated thrice. The growth parameters like plant height, leaf area index, number of tillers and dry matter accumulation were found highest under the T, which was found to be at par with T3 and T7, while significantly superior over rest of the treatments. Grain yield (q/ha) was found maximum under T, which was at par with T3 T6 and T7, while in case of straw yield (q/ha) it was only at par with T3 and T7 and significantly superior over rest of the treatments.
