Abstract
This experiment was conductee as a RCBD at a research farm at Kerman in Spring 2012 using millet and green pea as intercrop. The treatments were cultivation of sole nutrifid millet and green pea, 75% millet+25% green pea and vice versa, 50% millet+50% green pea, cultivation of mix seeds of two crops on the same row. The highest and lowest dry forage yield was obtained from sole millet and green pea. The ratio of 75% and 50% of millet was not significantly different with sole millet. Mineral nutrition uptake of intercrop was higher than sole ones. The intercrop treatments were not significantly different for N uptake, except for mixed cropping, while the highest uptake of P and K were recorded for 75% millet + 25% green pea. Mean RYT of 1.68 obtained from intercrop indicates the complementarity of two crops. Competition ratio of millet to green pea for N, P, K, Fe, Mn, Cu and Zn was more than 1 showing the higher competition ratio of millet compared to green pea. Aggressivity of millet was positive implying the dominancy of millet. Dry forage production near to sole millet, mean RYT of about 2 for mineral uptake, competition ratio of more than 1 and a positive aggressivity value indicates that 75% millet+25% green pea is the best planting ratio.
