Abstract:

Present study was undertaken to assess the response of rainfed maize to various fertility levels and weed management practices. A field trial was undertaken in 2012 and 2013 at Experimental Farm, D(K)ARS, SKUAST-Kashmir, (J&K). The experiment consisted of 3 fertility levels (F1=60:40:20, F2=75:50:30 and F3=90:60:40, N:P2O5:K2O kgha-1) and 4 weed management practices (W0=no weeding, W1=hand weeding 20 and 50 DAS, W2=atrazine @1.0 kg a.i.ha-1 (pre-emergence) + hand weeding 20 DAS and W3=atrazine @1.0 kga.i.ha-1 (pre-emergence) + isoprotron @1.0 kg a.i.ha-1 (post-emergence). The results revealed that fertility levels F3 and F2, at par with one another recorded significant increase in cob length, cobs plant-1, grains cob-1, 100-seed weight, grain yield, biological yield and stover yield as against F1, however, number of rows cob-1, cob diameter showed significant improvement with increase in fertility level from F1 to F3. Further, increase in fertility level from F1 to F2markedly enhanced the harvest index significantly but with further addition of fertility level it decreased significantly. Weed management practices W2 being at par with W3 recorded significant improvement in all yield contributing characters over W1 and W0. Both grain and stover yields were also significantly higher with W2 over W1 and W0, however, it was at par with W3.
