Response of snap bean (Phaseolus vulgaris l.) to soil moisture content and nitrogen fertilization under sandy soil conditions [electronic resource].

Includes references.

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./fed). on vegetative growth measurements, number and weight of podsl plant and yieldl fed. Photosynthetic pigments and chemical contents of snap bean (Phaseolus 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 Ifed. Similar results were obtained for relative growth rate (RGR) and net assimilation rate (NAR)
