Abstract
Two field experiments were carried out at the Experimental Farm of the Faculty of Agriculture, Suez Canal University, Ismailia, Egypt during the two spring successive seasons of 2003 and 2004 to investigate the effect of available soil moisture content (ASMC) of 40 %, 60% and 80% of the available water and nitrogen levels (0, 40 and 80 kg N.lfed). on vegetative growth measurements, number and weight of pods/ plant and yield/ fed. Photosynthetic pigments and chemical contents of snap bean (Phaseo/us vulgaris L.) under sandy soil conditions. Vegetative growth parameters (plant height, number of branches, shoot fresh and dry weights and leaves area, per plant) were significantly increased as available moisture or nitrogen rates increased. The interaction effect of the two factors showed that the highest values of all parameters were obtained from 80 % ASMC and 80 kg N /fed. Similar results were obtained for relative growth rate (RGR) and net assimilation rate (NAR) Yield and its components (number of pods, fresh weight of pods / plant and yield of green pods/ fed.) were increased with increasing of the available soil moisture or nitrogen application. The interaction revealed positive significant effect and the best yield was obtained from plants subjected to 80 available water % and.80 kg N/ fed. The leaves contents of chlorophylls a, b, total chlorophyll and carotenoids were increased with decreasing available soil moisture or increasing nitrogen level. On the other hand NPK and carbohydrate contents were significantly increased with increasing both available soil moisture content and nitrogen levels.
