Effect of weed management practices on growth and productivity of pigeonpea under greengram/ blackgram intercropping systems

Author(s): SK Singh, HS Kushwaha and Ram Bharose
Abstract: The field experiment was conducted at Agriculture Farm of Mahatma Gandhi Chitrakoot Gramodaya Vishwavidyalaya, Chitrakoot, Satna (M.P.) during the kharif 2016 and 2017 to assess the growth and productivity of pigeonpea under intercropping systems and weed management. The three intercropping system viz. sole pigeonpea, pigeonpea + greengram (2:2) and Pigeonpea + greengram (2:2) and seven weed management treatments viz. W1: Weedy check, W2: Pendimethalin 30 EC@ 1 kg a.i./ha, W3: Oxyfluorfen @ 0.2 kg a.i./ha, W4: Imazethapyr @ 0.1 kg a.i./ha, W5: Sodium Acifluorfen 16.50% EC+ Clodinofop-propragyl 8% EC, W6: Pendimethalin 30%+ imazethapyr 2% and W7: Imazamox 35% a.e.+ imazethapyr 35% were comprised in Split Plot design replicated as three. In intercropping system, plant height (149.84 cm), plant dry weight (41.0 g), seed yield (10.83 q/ha) and stover yield (26.94 q/ha) of pigeonpea were recorded significantly higher under sole pigeonpea followed by statistical at par with pigeonpea + greengram (2:2) intercropping system. In weed control practices, plant height, plant dry weight, primary branches and secondary branches/plant and seed yield (12.43 and 12.38 q/ha) of pigeonpea was recorded significantly higher under W6, pendimethalin 30% + imazethapyr 2% @ 1 kg/ha followed by W7, Imazamox 35% + imazethapyr 35% @ 30g/ha.
