Intercropping Two Varieties of Maize (Zea mays L.) and Peanut (Arachis hypogaea L.): Biomass Yield and Intercropping Advantages

Effect of different planting ratios of intercropping maize and peanut on Economical and Biological yield of maize (Zea maize L.) was evaluated in the Department of Agronomy, University of Zabol, during 2011. The treatments were compared in a randomized completely block design (RCBD) with nine planting ratios intercropping that were included. M: Sole maize var KSC 301(100% maize+0% peanut), M*: Sole maize var KSC 604 (100% maize+0% peanut), P: Sole peanut (100%peanut + 0%maize), MP: Intercrop of maize var KSC 301 50% + peanut 50%, M*P: Intercrop of maize var KSC 604 50% + peanut 50%, mP: Intercrop of maize var KSC 301 25% + peanut 75%, m*P: Intercrop of maize var KSC 604 25% + peanut 75%, Mp: Intercrop of maize var KSC 301 75% + peanut 25%, M*p: Intercrop of maize var KSC 604 75% + peanut 25%. The intercropped of maize and peanut in different planting ratio significantly affected the quantitative characters of the yield. The highest dry biological yield of maize (57.3t/ha) was obtained by sowing the crops in Intercrop of maize var KSC 604 75% + peanut 25%. The highest grain yield (10.0 t/ha) for maize was recorded from Sole maize var KSC 604(100% maize+0% peanut) and the highest dry biological yield for peanut (7.4 t/ha) was recorded from Intercrop of maize var KSC 604 50% + peanut 50%. The highest LER (2.30) and the lowest LER (1.27) was obtained by sowing the crops in ratio of Intercrop of maize var KSC 604 50% + peanut 50% and Intercrop of maize var KSC 301 25% + peanut 75% respectively. The results was shown that mixture were advantageous compared to both sole crops of maize and peanut.
