Abstract:

A field experiment was conducted during rabi season of 2013-14to 2015-16 on sandy clay loam soil at Regional Agricultural Research Station, Chintapalli, Andhra Pradesh to find out the efficient weed management practices of rajmash crop in high altitude and tribal zone. The experiment consists of twelve treatments involving different chemical combinations. The results indicated that among weed management practices adopted pre-emergence application of pendimethalin @ 0.75 kg ai/ha (1.0 lt/ac) + hand weeding at 30 DAS has recorded significantly higher weed control efficiency at 45 DAS and at harvest, yield and yield attributes. This treatment was on a par with the pre-emergence application of pendimethalin @ 0.75 kg/ha (1.0 lt/ac) + post emergence spray of imazythapyr @ 63 g ai/ha (250 m/ac) at 30 DAS. Highest benefit cost ratio was recorded with the application of Pendimethalin @ 0.75 kg/ha. (1 litre/ac) + imazythapyr @63 gm ai/ha 50 ml /ac) as post emergence at 30 DAS. Based on the results, either pre emergence application of pendimethalin along with one hand weeding at 30 DAS or pendimethalin @ 0.75 kg/ha (1.0 lt/ac) as pre emergence, followed by post emergence application of imazythapyr @ 63 g ai/ha (250 m/ac) at 30 DAS can control weeds efficiently in rajmash crop and produce higher yield.
