| Abstract | ||
| Two field experiments were carried out on faba bean under a drip irrigation system, during 1997/1998 and 1998/1999 seasons, to study the effect of three watering levels {513.37 (11), 1026.74 (b) and 2053.48 (13) m3/fed.} on the growth and yield of Giza 3 (V1) and Giza 429 (V2) varieties. A split plot design with three replications was used, where irrigation levels occupied the main plots, meanwhile the . sub-plots were devoted to the two varieties. Water use efficiency W.U.E. was calculated for ali the combination treatments. correlation and relative contribution of some traits were calculated under each of the independent five treatments. The obtained results revealed significant increments in all traits except 100 seed weight, were secured by varying watering level from h to b. Thereafter increments were insignificant. Seed yield Ifed. in the two respective seasons, viz. 840.0 and 813.5 kg. were detected for 12. The V1 out yielded V2 in both seasons. The combination la x V1 produced the highest seed yield, in both seasons, but without significant difference with 12xV1. Water use efficiency (W.U.E.) was the highest in both seasons for the 12xV1 treatment. Moreover the combination of either 12 or V1 with others produced the soundly W.U.E. With few exceptions, traits were positively correlated to each other, where all correlation coefficient with seed yield I plant were significant. The 100 seed weight always showed insignificant correlations. Frequency of correlation coefficient was higher by increasing water supply and using V2. It seemed that plant height, no. of branches I plant and no. of pods I plant were the main contributors to seed yield I fed. Their total contribution amounted to 62.49, 84.17, 73.70, 67.36 and 62.52% through the treatments of 11, 12, la, V1 and V2, respectively. | ||
