| Abstract | ||||
| Two field experiments were carried out in the Research and Experiment Center, Faculty of Agriculture at Moshtohor, Zagazig University during 1997l1998 and 1998:“! 999 seasons. This investigation aimed to study the effect of irrigation treatments (single, two and three irrigations] and potassium fertilizer rates (0, 16, 32 and 48 kg KZO/fed) on yield and its components of faba bean. The results showed that, increasing number of irrigation from single to three irrigations caused significant increases in number of podsfplant, number of seedslplant, weight of podsrplant. weight of seedsfplant, shelling percentage and weight of 100 seeds. Also, such increase in number of irrigations induced significant increase in seed yield (kgifed) and testal'seed percentage. Whereas, cotylelseed percentage was decreased by increasing the number of irrigations in both seasons (from 1 to 3). These results were true in each of the two growing seasons. Regarding soil potassium application. using a rate of 48 kgifed recorded the highest significant values of number of podsi’piant. number of seedslplant shelling percentage. weight of 100 seeds and seed yield (kg/fed) and cotyl tseed percentage. Whereas, testai‘seed percentage reduced with increasing potassium fertilizer rates in both seasons. it could be concluded that for maximizing seed yield of faba bean and its quality by irrigation three times at 30, 60 and 90 days from planting and addition potassium fertilizer at 48 kg KZOIfed under the experimental conditions of Kalubia district. The interaction between number of irrigations and potassium fertilizer significantly affected number of seedtpiant, weight of seedsiplant and seed yield (kglfed) in the first season and weight of podstplant in the second season. irrigation three times and increasing potassium fertilizer levels up to 48 kg KgOtfed significantly maximized number of seedfpiant, weight of seedstplant and Seed yield (kgifed). However, irrigation two or three times and addition 48 kg KZOtfed produced maximum weight of podstplant without significant differences. | ||||
