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
