неизвестный. A field experiment was carried out during two winter seasons in the Experimental Station of the Faculty of Agriculture, University of Assiut at El-Ghorieb (Typic Torripsamments) to study the effect of farmyard manure application and late foliar nutrition with nitrogen during the pod-filling stage on yield, N, P and K contents of some faba bean varieties. Twenty seven treatments were used to represent the combinations of 3 varieties (Giza 674, Giza 2 and Giza 402), 3 farmyard manure levels (0, 10 and 20 m3/fed) and 3 regimes of nitrogen spray (one early spray at the pre-flowering stage, one late spray at the pod-filling stage and two sprays at both stages). The obtained results could be summarized as follow: - The straw and seed yield as well as nutrient contents in the seeds increased by farmyard manure application. - Giza 674 variety gave higher mean values for straw and seed yields as well as total N, P and K contents in seeds compared with Giza 2 and Giza 402 varieties. - The late foliar spray (at the pod-filling stage) had significant effects on the yield (straw and seed) as well as the total contents of N and K compared with the early spray at the pre-flowering stage. - In presence of farmyard manure, foliar spray with urea showed no clear effect on the studied parameters. Faba bean seed yield and quality can be improved through the supplementary foliar fertilization with N during the pod-filling period and/or farmyard manure application to meet the high N requirements of faba bean plants during the late stages of pod development.
