| Abstract | ||
| Two experiment were carried out during the two growing seasons of 2010/2011 and 2011/2012 at Giza Agric. Res. St. to study the effect of plant density of faba bean intercropped on wheat and nitrogen fertilization on yield and its components for both crops. A split plots design with three replications was used. The main plots were devoted to nitrogen fertilizer levels (60, 75 and 90 kg N/fad. Whereas, the sub plots were allocated for pattern systems P1,P2,P3 (100 wheat 12.5%, 25% and 37.5% faba bean respectively. The results indicated that increased population of faba bean from 12.5 % to 37.5 of solid led to reduction for all study characters number of spikes/m2, grain/ spike, weight of grains spike and 1000 grain, grain and straw yield/ fad of wheat in the combined data. The reduction in grain and straw yield of wheat were estimated 5.84 and 6.47 for P1, 10.09 and 8.82% for P213.33 and 13.53% for P3 respectively. Intercropping 100% of wheat with faba bean (P1) recorded the highest values of most yield components of faba bean, while the lowest values were observed by third density (P3). Seed and straw yield were increased by increased plant density of faba bean (P1 toP3) but reduced as compared with solid yield. This in seed and straw yieldfaba bean were 75.57 and 76.24 for (P1) 61.48 and 66.70 for (P2) 47.60 and 55.55 for (P3) respectively.Grain and seed yield of wheat with faba bean were significantly affect by nitrogen fertilizer levels. The highest values of both crops (95.24 and 48.75) were observed when added 90 kg N/fad. While the lowest values (85.63 and 29.33) with 60 kg N/fad of solid crops. The highest of LER (1.53) MAI (4574.73) and MER (1.42) were observed (N3×P3) while the lowest was observed (N1×P1). The values ofaggressivity (Ag) for faba bean was positive while wheat was negative it means that faba bean was dominated while wheat was dominated. | ||
