- Abstract
A field experiment was conducted during summer season 2016 at Annamalai University, Experimental Farm, Annamalai Nagar, to study the efficiency of pre-emergence herbicide and cultural methods of weed management on growth and yield of hybrid cotton the experiment was laid out in Randomized Block design with three replication and eight treatments. The treatments viz., T1 - unweeded control. T2 - twice and weeding on 20 and 45 days, T3 - Pre-emergence application of pendimethalin 0.68 kgha-1, on 3 DAS, T4 - Pre-emergence application at pendimethalin 0.68 kgha-1 on 3 DAS + One hand weeding on 45 DAS, T5 - Pre-emergence application of pendimethalin 0.68 kgha-1 on 3 DAS + intercropping with (blackgram); T6 - Pre-emergence application of pendimethalin 0.68 kgha-1 on 3 DAS + mulching on 21 DAS, T7 - intercrop alone and T8 - mulching alone. Observation on total weed count, weed biomass, and weed control efficiency were recorded cotton yield attributes and seed cotton yield were observed. Results of the experiment it can be concluded that application of pre-emergence herbicide pendimethalin 0.68 kgha-1 + intercrop with blackgram recorded higher seed cotton yield and maximum economic returns in hybrid cotton beside obtaining broad spectrum weed control throughout the crop growth period.
