Abstract:
Rice (Oryza sativa L.) is one of the most important stable food crops in the world. The present study was taken at Garaila, Jaunpur, U. P to evaluate the effect of integrated use of organic and inorganic nitrogen with and without zinc sulphate on performance of rice in alkali soil. The experiment was laid out in randomized block design with 9 treatment with 4 replication, treatment consist of control (no fertilizer), NPK, Zinc and press mud. The result reveal that highest plant height of rice at harvest (125.58 cm),number of tiller per meter at 90 DAT (78.56), number of panicle per meter row (46.38), number of grain per panicles (126.43), test weight (gm) (24.00), grain yield quintal per hectare (48.87), straw yield quintal per hectare (74.44) and harvest index (%) (39.63) was found from T8 [60 kg N (press mud) + 60 Kg nitrogen + Zinc] and closely followed by T9 [90 kg N (press mud) + 30 Kg N + zinc] the organic press mud reported higher in most above parameter. 100% nitrogen recorded significantly lower as compare to T8 and control plot recorded lowest of all above parameters. The study showed integrated use of organic with fertilizer produce higher and sustainable yield of rice.
