The field experiment to determine “Effect of different weedicides in pigeon pea [Cajanus cajan (L.) Millsp] + green gram (Vigna radiata (L.) Millsp) intercropping system under rainfed condition in Kymore Plateau of Madhya Pradesh” during kharif and rabi seasons in the year 2012-13 was conducted at the Rajoula Research Farm, M.G.C.G.V., Chitrakoot, Satna, Madhya Pradesh. Present experiment has been designed to select the appropriate weed management practice in pigeon pea cultivation as the weed management has its own importance in terms of yield and economics. The aim of this stydy to assess the most suitable weed management practices for pigeonpea + green gram intercropping system. Results revealed that intercropping system pigeon pea + green gram (2:2) is an superseding cropping system in respect to crop growth, root and root nodulation, yield attributes, yield and economics as compared to alone pigeon pea or green gram. Whereas, the application of pre emergence weedicide Pendimethelin @ 1.0 kg ai with post emergence weedicide Imazethapyr @0.1 kg ai/ha (W5) or by pre emergence weedicide Oxyfluorfen @ 0.2 kg ai/ha with post emergence weedicide Imazethapyr @ 0.1 kg ai/ha ((W6). These weedicides were found efficient in controlling weeds and in relation to higher yield attributes, seed and straw yield of pigeon pea and green grammost appropriate, profitable and productive treatment combination for pigeon pea and green gram intercropping system. In case of economics of intercropping system I2: pigeon pea + green gram (2:2) was found better in terms of benefit: cost ratio.

On the basis of the results obtained from the experiment, It can be concluded that, under intercropping system based on pigeon pea + green gram (2:2) is an superseding cropping system in respect to crop growth, root length and root nodules, yield attributes, yield and befit cost ratio as compared to alone pigeon pea or green gram. Weed can be managed efficiently by application of the pre emergence weedicide Pendimethalin @ 1.0 kg ai with post emergence weedicide Imazethapyr @0.1 kg ai/ha (W5) or by pre emergence weedicide Oxyfluorfen @ 0.2 kg ai/ha with post emergence weedicide Imazethapyr @ 0.1 kg ai/ha ((W6). These weedicides were found efficient in controlling weeds and in relation to higher yield attributes, seed and straw yield of pigeon pea and green gram. Under intercropping system I2: pigeon pea+green gram (2:2) combined with pre emergence application of Pendimethelin@ 1.0 kg ai or Oxyfluorfen @ 0.2 kg ai/ha with post emergence application of Imazethapyr @ 0.1 kg ai/ha was most appropriate, profitable and productive treatment combination for pigeon pea and green gram crops under rainfed area of Kymore plateau of Madhya Pradesh. Economics of intercropping system I2: pigeon pea + green gram (2:2) was found better in terms of benefit: cost ratio.
