| Abstract | ||
| In order to water deficit has become the major limiting factor on the productivity and sustainability of agriculture, especially in arid and semi-arid regions. It could be achieved through two field experiment were carried out during 2016-17 and 2017-18 seasons at the agricultural experimental station farm of Water Studies & Research Complex (WSRC), National Water Research Center, located in Toshka at Abu-Simbel Region, to investigate out the impact of irrigation water regimes (Ir 1 =60, Ir 2 =80 and Ir 3 =100 % of ETc, which were applied using a sprinkler irrigation system) with the foliar applications of indole acetic acid (IAA) application (In 1 =0, In 2 =50 and In 3 =75 ppm) and kinetin (Kn 1 =0, Kn 2 =20 and Kn 3 =40 ppm) on growth, seed yield and quality of faba bean plants (Nubaria 1) as well as the water crop productivity (WCP). The experiment was laid out in strip-split plot design with 3 replications.The obtained results could be summarized as follows: Increasing the applied amount of irrigation water from 1458 (Ir 1 ) to 2430 m 3 fed -1 (Ir 3 ) gave the highest values of all growth characters, except plant height in average values of both seasons. Nevertheless, the application of 100 % ETc (Ir 3 ) resulted in increases in the values of yield and its attributes as well as P and K contents of seeds. The highest values of (WUE), (WCP) and seed quality (protein content) occurred with 60 % ETc (Ir 1 ) of irrigation water level. The growth traits, yield and its attributes, as well as chemical composition of faba bean values and water parameters increased with increasing IAA and kinetin concentrations to 75 and 40 ppm, respectively. With respect to the interaction of the three studied factors, Ir 3 (100 % ETc), In 3 (75 ppm) and Kn 3 (40 ppm) gave the highest values for plant height, leaf area index, total chlorophyll and No. of branches plant -1 .Seed yield was positively significantly and correlated to the leaf area index, total chlorophyll, root length, plant fresh and dry weights, No. of branches and leaves plant -1 , No. of pods plant -1 , 100-seed weight and pod yield plant -1 whereas, the plant height was significantly negatively correlated to seed yield.Therefore, it is recommended to grow faba bean plants (Nubaria 1) with applying 2430 m 3 fed -1 of irrigation water and foliar spraying indole acetic acid (IAA) and kinetin at levels 75 and 40 ppm, respectively to obtain high seed yield and quality of faba bean. | ||
