The present study was undertaken to find the cheap and effective methods of weed management on one hand and to get complementary yield on the other hand. The present study was conducted during 2009 & 2010 at the Model Organic Farm of Department of Organic Agriculture, CSKHPKV, Palampur. Legume intercrops in maize viz., soybean, cowpea and dhaincha were grown in additive series in 1:1 and 1:2 proportion for both seed and green manure purposes and were compared with pure maize crop, weeded once, twice and with no weeding. All the intercrops reduced dry weight of weeds and increased the maize equivalent yield significantly as compared to unweeded check during both the years. In general, the legume crops grown for seed purpose produced higher equivalent yield as compared to green manure which was incorporated into the soil after 45 days. Irrespective of different legumes the weed suppression was generally more in 1:2 proportion as compared to 1:1 proportion, which ultimately resulted in higher maize equivalent yield in 1:2 as compared to 1:1 proportion of maize : legume. The maize equivalent yield in maize + cowpea (1:2) as seed crop (3.40 & 3.58 t/ha during both years, respectively) was at par with maize + soybean (1:2) as seed crop (3.24 t/ha) in first year and with maize + cowpea (1:1) as seed crop (3.42 t/ha) in second year of experimentation. Maize + dhaincha (1:1) and (1:2) as green manure and maize alone with two hand weedings during the first year whereas, maize + cowpea as seed crop (1:1) and maize alone with two hand weedings during second year produced significantly higher yield and lower weed dry weight as compared to other treatments.
