Abstract:
An experiment was conducted to evaluate the effect of weed management practices on soil pH, bulk density, organic carbon and availability of N, P, and K during 2016-17 at A. N.D.U.A. &T., Kumarganj, Ayodhya. The result showed that maximum decline in soil pH, B.D. and increase in organic carbon status and maximum buildup of availability of N, P, K observed in the treatment applying paddy straw mulch @ 10 t/ha followed by 5 t/ha paddy straw mulch as compared to non-mulched treatments of 4 H.W. alone, integrated Herbicide (Metribuzin as P.E.) with two H.W. and weedy check. The treatment consisting of paddy straw mulch @ 10 t/ha found most superior in improving physico-chemical property and availability of N.P.K.
