The soil of the experimental field was loamy sand, normal in pH and electrical conductivity, low in available N, medium in available P and K. The experiment was laid out in randomized complete block design with four replications. The treatments consisted of three cultivars of oilseed rape viz., GSC 6, GSC 7 and Hyola PAC 401 intercropped with garden pea (Punjab 89) in 1:1 (Furrow 60 cm), 1:1 (Flat 60 cm), 1:2 (Flat 90 cm) row proportions, sole GSC 6 (Flat 30 cm), sole GSC 7 (Flat 30 cm), sole Hyola PAC 401 (Flat 30 cm), sole garden pea (Ridge 60 cm) and sole garden pea (Flat 30 cm). Seed yield of oilseed rape cultivars viz., GSC 6, GSC 7 and Hyola PAC 401 were not significantly influenced by different intercropping treatments. Flat sown sole pea produced highest green pod yield which was significantly higher than all other treatments. Significantly higher equivalent yield and system productivity of oilseed rape cultivars was recorded in different intercropping systems with garden pea as compared to the sole oilseed rape crop stand. Land equivalent ratio of different intercropping systems was more than one and was highest in furrow sown Hyola PAC 401 + ridge sown garden pea in 1:1 row ratio (1.18). All the oilseed rape based intercropping systems resulted in higher gross returns when compared to their sole crop stand. Intercropping of GSC6 , GSC 7 and Hyola PAC 401 with garden pea in either 1:1 or 1:2 row ratio makes oilseed rape intercropping system more remunerative because of increase in the net returns to the tune of ` 4,200 to `11,000 ha-1.ennullThesis
