| Abstract | ||||
| A field trial conducted on barley, lupin and chickpea crops was practiced in sand loamy newly reclaimed soil at the experimental farm of the Faculty of Agriculture, Fayoum University, during 2006/07 and 2007/08 seasons. This work was designed to study the effect of nitrogen fertilizer rates (15, 30 and 45 kg N/fed.) on the three crops grown as sole and intercropping (barley/chickpea and barley/lupin). A split split-plot arrangement in randomized complete block design with three replications was used. The obtained results showed that, compared with the barley/chickpea pattern, monocrop chickpea had significantly improved yielding and quality traits. Whereas, intercropping had higher seed index. Fertilization with 45% N (N3) led to increases in vegetative and reproductive and consequently seed yield/fed. However, similar means of height to first branch and seed index were obtained from application of 30 kg N/fed. (N2) which produced the highest harvest index. Compared with monocrop culture, barley/lupin intercropping resulted in significant increases of lupin height traits in addition its superiority for number of branches and seed index but with inferior seed weight/plant. The heaviest weight of seeds/plant and yield/fed. were obtained from soled lupin. Nitrogen application results revealed the adequacy of N3 for lupin where it produced acceptable seed yield/fed. due to its superior number of pods and harvest index. Except seed and harvest indices all barley traits were significantly affected by intercropping in favour to soled culture. Intercropping barley produced more than half yield/fed. Compared with solid culture. Nitrogen fertilization indicated the suitability of N2 (30 kg N/fed.) for producing improved yield insignificantly different from that of N3. Under cropping patterns with N2 fertilizer dose, the second yielding combinations were barley/chickpea (12.18 ard) and then barley/lupin (11.08 ard) which represented 61 and 55% of yield of soled barley fertilized with N3. These results indicating that chickpea was of better effect than lupin on barley yielding ability and fertilization with the intermediate nitrogen dose (N2) was quite enough for intercropping. Also, with N2 barley/chickpea and barley/lupin yielded 49% chickpea together with 61% barley with LER of 1.15 as well as 46% lupin together with 55% barley with LER 1.21, respectively, compared with sole culture of each crop. These two intercropping –N2 combinations increased total production by 15% and 21% respectively. | ||||
