Abstract
An experiment entitled, "Effect of non-chemical weed management practices in growth and yield of basmati rice” was conducted at the Organic Farming Research Centre, Chatha of SKUAST- J. during Kharif season of 2019-2020. The soil of the experimental site was sandy clay loam in texture, The experiment consisted of 13 treatments viz.,T1-Stale bed fb one hand weeding at 30 DAT, T2-Wheel hoeing at 20 & 40 DAT, T3-Rice straw mulch @ 2.5 t/ha, T4-Rice straw mulch @ 5.0 t/ha, T5-Azolla 1.0 t/ha,T6-Mustard seed meal (MSM) @ 2.5 t/ha at 10 DBT,T7-MSM @ 1.25 t/ha at puddling, T8-MSM extract with MSM @ 0.4 t/ha at 5 DBT T9-MSM extract with MSM @ 0.6 t/ha at 5 DBT T10-MSM extract with MSM @ 0.8 t/ha at 5 DBT T11-MSM extract with MSM @ 1.0 t/ha at 5 DBT T12-Weed free,T13-Weedy check. Stale bed fb one hand weeding at 30 DAT and Wheel hoeing at 20 & 40 DAT resulted in significant increased of growth parameters viz. plant height, dry matter accumulation and leaf area index at 60, 90 and at harvest and also found lowest weed dry matter. Among the different non chemical weed management practices, stale bed fb one hand weeding at 30 DAT gave higher grain yield (3047 kg//ha) and followed by Wheel hoeing at 20 & 40 DAT (2958 kg/ha).
