Abstract

This research trial was executed at Gemmeiza Agric. Res. Station from 2004 through 2006 in order to find out the effect of alternate-furrow irrigation (AFI) as combined with fertilization rate on water and fertilizer utilization efficiencies for pea, sunflower and faba bean crops grown in a sequence. The results can be summarized as follows :- 1- Modified alternate-furrow irrigation (MAFI) significantly surpassed both every- furrow (EFI) and alternateefurrow irrigation (AFI) methods in increasing the yield of crops under study. 2- Generally1 AFI, as compared to (ER), resulted in reduction in water applied for the crops under study, however, the reduction reached significance level with pea and faba bean crops. Moreover, AFI reduced the water applied, throughout entire experiment, by about 13%cornparable with EFL. 3- Water Utilization Efficiency( WUtE) and Fertilizer Use Efficiency(FUE) for pea and sunflower crops were enhanced under MAÑ ,while for faba bean the enhancing was under both AFI and MAÑ techniques, as compared with ER one. 4- The recommended rate of K and P-fertilizers significantly increased yield of pea and faba bean crops, respectively, whereas with over- recommended rate the increases did not reach the significance level, comparable with the under- recommended rate. Sunflower yield was gradually increased with both recommended and over-recommended N-rates, as compared with the under- recommended rate. 5- The recommended K-fertilizer rate resulted in highly significant increase in water applied for pea crop, while the over-recommended rate did not exert significant effect to alter such parameter, comparable with under-recommended rate. Both recommended and over-recommended P-rates insignificantly affected the water applied for faba bean crop. Nevertheless, water applied for sunflower crop was highly significant increased due to recommended and over-recommended N- rates, as compared with under-recommended one. 6- Values of WUtE for pea and faba bean crops gradually increased with recommended and over-recommended K and P-fertilizer rates, comparable with under-recommended rate however, the increases% were more pronounced with pea crop. A differed trend was observed with sunflower crop since WUtE values were gradually ¡mproved due to recommended and over-recommended N-rates 7- In general, FUE values for the crops under study were higher with recommended fertilizer rate and then tended to gradual reduction with recommended and over-recommended rates. 8- After harvesting each crop, value of the available tested fertilizer element was increased under MAFI technique, as compared with EFI and AR ones. 9- At the experiment end, higher values of soil organic matter% and available N, P and K contents were observed with MAFI technique, comparable with EFI and AFI ones.
