Abstract:
A field experiment was conducted at ‘Til Research farm’ College of Agriculture, Tikamgarh during Kharif season of 2011-12 and 2012-13 to find out the efficacy of herbicides on weed intensity, dry weight, yield and economics of sesame. The treatments comprised of pre emergence herbicides viz. oxyfluorfen at 250 and 500 g/ha, pendimethalin at 200, 400, 600, 800 and 1000 g/ha, one hand weeding at 15 DAS + one hand hoeing at 30 DAS, two hand weedings and weedy check. The major weed species observed in the experimental area were Cyperus rotundus, Echinochloa crusgalli, Digitaria adscendens, Euphorbia hirta and Phyllanthus niruri. The relative density of monocots was 75.50% while dicots were to the extent of 22.99% of the total weed population. Hand weeding was found superior to other weed control measures and attained minimum weed density, dry matter and maximum weed control efficiency followed by one hand weeding + one hand hoeing at 15 and 30 DAS during both of the year. Among the herbicides, pre emergence application of oxyfluorfen @ 500 and 250 g/ha produced significantly higher yield over all the rates of application of pendimethalin. The highest net monetary return obtained with two hand weedings whereas the B:C ratio was the highest with the application of oxyfluorfen at 250 g/ha followed by oxyfluorfen at 500 g/ha and pendimethalin at 600 g/ha.
