| A field trail was carried out at Sakha Agricultural Research Station, Kafr El-Sheikh Governorate during the two successive winter growing seasons 2008/2009 and 2009/2010. Treatments were: A received 4 irrigations excluding planting irrigation, B received three irrigations after planting watering, C received two irrigations, the first was following sowing and the second was the third as applied for the treatment A, D received two irrigations after the sowing during flowering and maturity stages, E received one irrigation along with sowing irrigation and F was left for rainfall only (without irrigation) after applying the planting watering. The main target for the current study was to investigate the influence of number of irrigations on faba bean yield, its components and also on some water relations. The main findings of this study could be concluded as follows: The highest values of water applied [irrigation water (IW) + rainfall (Rf)] were recorded under treatment A (control without stress) which received the high number of irrigations (5 including the sowing) and the seasonal value was 1601.46 m3/fed. (38.13 cm). On the contrary, the lowest value was recorded under the conditions of rainfed treatment (F) of 609.41 m3/fed. (14.51 cm). Also, data clearly illustrated that watering with treatment (B) which received three irrigations excluding the planting one resulted in saving water of about 176.08 m3/fed. (4.19 cm) equivalent to 61 million m3 at the national level. Such saving of water could be used for cultivation new areas. Regarding crop consumptive use (ETc), data illustrated that with increasing the number of irrigations up to 4.0 excluding the planting one gave the highest seasonal value for crop consumptive use (ETc) comparing with other treatments. The seasonal values for ETc can be arranged in descending order as; 36.93 > 32.60 > 26.60 > 25.05 > 17.09 > 12.37 cm for A, B, D, C, E and F treatments, respectively. Concerning seed yield (kg/fed.), the highest mean values were recoded under irrigation treatment (B) which received three irrigations following sowing comparing with treatment (A), which received three and four irrigations after sowing, respectively. The mean corresponding values were 1403.33 and 1497.5, kg/fed., respectively. On the contrary, the lowest mean values were recorded under irrigation treatments (E and F) and the mean values were 780.0 and 560.0 kg/fed. in the first and second growing seasons, respectively. Regarding, all studied parameters such as plant height (cm), 100-seed weight (g), number of pods and number of branches, the highest mean values were recorded under irrigation treatment (A) which received the highest number of waterings. On the other hand, the lowest mean values were recorded under irrigation treatment (F) which left for rainfall during the growing season after planting irrigation. | ||||
