Effect of Organic Manures on Yield and Yellow stem borer infestation in Semi Deep water Rice
2010
Prasad, S.S. | Gupta, P.K.
Field trials were conducted to manage yellow stem borer (YSB) population using organic manures alone or in combination with nitrogenous fertilizer in a semi deep water rice. The results indicated that organic manures, viz press mud @ 10 ton/ha, vermicompost @ 2.3 ton/ha and green manuring with Sesbania acculeata @ 40 kg seed rate recorded significantly low average YSB infestation of 3.4, 3.7 and 4.4%, respectively, incomparison to recommended dose of inorganic fertilizers with 8.8% average YSB infestation. Also the combination of green manuring with S. acculeata @ 40 kg/ha seed rate and 50% N as top dressing with moderate infestation of 6.6%, was found most effective in increasing rice grain yield to 2.20 ton/ha in comparison to 3.3% YSB infestation and 1.12 ton/ha mean yield.
