Abstract

In order to evaluate the NITROGEN FERTILIZER levels on yield and yield components of FORAGE MILLET (Pennisetam americanum var. Nutrifeed) and COWPEA (Vigna unguiculata var. Parastu), an experiment was conducted in Research and Educational farm of College of Agriculture, University of Tehran at 2002. The treatments were arranged in split plots based on Randomized Compelete Block Design with four replications. Four levels of NITROGEN FERTILIZER (46% of N) of 0, 100, 200 and 300 kg/ha were assigned to the sub- plots including (S1:sole cropping of millet, S2:sole cropping of COWPEA, S3:cowpea 50% + millet 50%, S4: COWPEA 25% + miller 75% and S5: COWPEA75% + millet 25%). A replacement system was used for the INTERCROPPING pattern. According to the result of this experiment COWPEA produced the maximum grain yield of 820 kg/ha at 100 kg/ha of urea application while the minimum grain yield (378 kg/ha) was obtained 300 kg/ha of urea utilization. The least amount of millet forge (36723 kg/ha) was obtained in COWPEA75% and millet 25% sowing pattern. The grain yield of COWPEA was increased as the percent of its contribution in INTERCROPPING patterns was increased (from 141.2 kg/ha in S4 to 900.7 kg/ha in S2). Application of 200 kg/ha of urea increased LER by 37% compared to sole cropping. It is concluded that COWPEA and millet make a more efficient use from Agricultural inputs in INTERCROPPING compared to their sole cropping.
