SUPPRESSION OF HARMFUL EFFECT OF WATER DEFICIT STRESS ON Vicia faba L. AND SIMULTANEOUSLY MANAGEMENT OF SOME INSECT PESTS

In Egypt, the irrigation water deficit is one crops production troubles, and thereby saving irrigation water is the main target for our country. So, a field trial was executed aiming to assess the impact of irrigation water requirements such as 100, 80 and 60% of irrigation requirements (IR), compost as soil addition [with compost or without] and foliar application of pesticides [control (without), chemical pesticide and bio pesticide] on the performance of faba bean during two different stages. Through irrigation rates, may be controlled insects movement and their presence. However cannot prevent the insect from damaging the crops, in this experiment, reading the behavior of Insects was done then monitoring according to their behavior. The results indicated that faba bean plants irrigated with 60 % of IR had a low growth performance as well as yield traits compared to faba bean plants irrigated with 80% of IR , which came in the second-order, then the faba bean plants irrigated with 100% of IR which realized the highest growth performance as well as yield traits. Soil treated with compost caused improvement in the growth performance as well as yield traits compared to the corresponding soil without compost. The highest infestation was observed in 100% irrigated with 65.55 and 74.53 aphids/ ten leaves in the two seasons, respectively, however, the lowest aphid number was recorded in 80% irrigated with 33.87 and 30.28 aphids/ ten leaves in the two seasons, respectively, followed insignificantly by 60% irrigated in the second season. The foliar application with two pesticides (Chemical and Bio) reduced aphid infestation by about 50% and 30%, respectively, compared with control in both seasons. It is clear that the two pesticides did not differ significantly in both seasons and the control recorded 58.22 aphids/ ten leaves, respectively, in the first season, and 55.65 aphids/ ten leaves, respectively, in the second season.
