| Abstract | ||||
| SAVING IRRIGATION water and thereby increasing crop water- ……use efficiency are especially important in water-scarce regions. For that, a greenhouse experiments were carried out during the winter season of 2012 and 2013 at the Army Farm, El Amria region, Alexandria, Egypt in order to study the effect of line depth placement of drip lines and different levels of molybdenum on two common bean varieties .Irrigation systems,( surface drip irrigation (SDI) , subsurface drip irrigation at 15cm and 30 cm. were arranged as main plots . Two green beans varieties 'Bronco' and 'Paulista' were arranged within each irrigation system (greenhouse) and were considered as sub-plot. Ammonium molybdate concentrations (0, 0.25, 0.50 and 1 g/ L. water) were arranged within each variety and considered as sub-sub plot. The obtained results could be summarized as follows ; generally the subsurface drip irrigation at 15 cm was the best irrigation treatment for foliage fresh weight, number of nodules per plant , early yield / plant , number of pods /plant and total yield of green pods / plant and per plot. However, application of ammonium molybdate levels 0.25 or 0.5 gm./L. had significant effect on leaf area/ plant , root length and number of nodules /plant . No significant difference between Bronco and Paulista on total yield. The Highest significant total yield of green pods plant-1 and yield of green pods plot-1 (654.17 g/plant and 15.70kg /plot) were obtained when "Bronco" cultivar plants grown under subsurface drip irrigation system at 15 cm depth (SSDI-15) and sprayed with 0.50g ammonium molybdate. | ||||
