Abstract
The influence of different weed control practices on cotton cv. NIAB 78 and some Kharif weeds under two fertility levels on a sandy clay loam soil was investigated in a field trial during 1987-88. The results revealed that hand weeding (3 hoeings) was most effective in reducing weed biomass by 72.5%. Plastic mulch and wheat straw mulch were also effective in suppressing weed dry weight by 63.5 and 21.5%, respectively but were un-economical due to high cost of plastic and straw. Pendimethalin and Haloxyfop were effective against Trianthema portulacastrum L. but had little effect on Cyperus rotundus L. These herbicides had no phyto toxic effect on . cotton germination and growth. Incorporation of wheat roots inhibited weed biomass upto 9% but cotton plant height by 14.3%. The effect of wheat roots on cotton was mitigated uiith the addition of f
