Effect of irrigation level and nitrogen fertilizer on water consumption and faba bean growth

Abstract

Abstract A field experiment was conducted in Babil governorate to find out the effect of water tightening with different irrigation levels and fertilization with different urea levels on water consumption of pests and some of its characteristics. Agricultural land was selected and prepared for cultivation and the field was divided. It was treated with three levels of irrigation, which are (30, 50, 70) % of the ready water, and three levels of urea, which are (0, 50, 100) kg urea. After the end of the experiment, the actual water consumption, the reference water consumption and the yield factor were calculated. The water consumption was (562, 482, 382) mm for each of the levels of irrigation (30, 50, 70)% of the prepared water, respectively. As for the characteristics of the plant, it was found that the best treatment that achieved good productive and vegetative characteristics is the treatment of depletion of 30% and the level of urea 100 kg, as the values reached (75.3, 83.2, 20, 5284) for each of the plant height, dry weight, number of branches and seed yield respectively.. The water stress reduces plant productivity due to water stress, as well as the high level of urea, which helped improve plant properties.
