| Abstract | ||
| Field experiments were conducted at Tag El-Ezz Agric, Res. Station, Dakahlia Province Egypt, during the two successive winter seasons of 2008/2009 and 2009/2010 to study the effect of two preceding summer crops ( rice and maize) and five irrigation systems i,e. full irrigation every 30 days (control), irrigation every 40 days and skipping of 1st, 3rd and 4th irrigation at 30, 90 and 120 days on growth and yield of faba bean (sakha 1) planting at 60, 120 and 180 cm ridges width. Preceding summer crops, irrigation systems and ridge width had significant effect on all studied characters in both seasons. Seed yield of faba bean grown after maize attained an increase of 15.9 % (average of two seasons) compared after rice. Irrigation of faba bean every 30 day recorded the highest values in all studied characters in both seasons. Seed yield under full irrigation increased by 4.5, 28.5, 43.9 and 19.2 % (average of two seasons) compared to every 40 days and skipping of 1st, 3rd and 4th irrigation, respectively. Planting faba bean on ridge at 120 cm width gave the highest values in all studied characters in both seasons except straw yield, at which seed yield recorded up 5.0 and 14.5 % increment compared with 60 and 180 Cm width, respectively. Faba bean planting after maize on ridge 60 cm width with full irrigation gave the highest seed yield (14.5 ardab/fad). On the other hand faba bean planting after rice on ridge of 120 cm width with irrigation every 40 days attained the highest seed yield (13.8 ardab/fad) as average of two seasons. The simple correlation co-efficient cleared significant positive correlation between seed yield ardab/fad and each of individual studied characters, also cleared that there were significant positive correlations among all studied characters and each other. Multiple regression analysis indicated that the relative contribution for all characters were 89.81 % from the total variation for yield. Analysis of stepwise regression revealed that five out of seven variables contributed by 89.81 % in the total variation for yield. These variables were seed yield/plant, 100-seed weight, plant duration, plant height and no. of pods/plant. The present investigation recommended cultivation of faba bean after maize at 60 Cm ridge width with full irrigation ( 4 irrigations, 30 days interval) or after rice at 120 Cm ridge width with (3 irrigations, 40 days interval) were the effective treatments for improving faba bean productivity under El-Dakhlia region condition. | ||
