Abstract
Two field experiments were conducted during the two summer seasons of 2017 and 2018 a special farm ,in El Mansoura , Dakahlia Governorate on the first week of May in a complete randomized block design to evaluate effect of Gaucho(G) systematic insecticides as seed coating before sowing against sucking pests which attack cowpea (Kaha -1 cultivar) during seedling period ( from emergence until 60 days old ) as compared with untreated seed (control) also, Gaucho spraying (Gs), K.Z.oil and integrated nutrients management (I.N.) Fe + Zn + Mn + Cu rate of 0.3,0.3,0.3 ,0.15 gm L-1, respectively as EDTA chelated form with potassium sulphate soaked rate of 10 gm L-1 , three times through growth stages on vegetative growth characters , Photosynthetic Pigments ,Yield , Yield components and Chemical constituents ,quality and suckinginsect pests .It can be observed from the results that all parameters for both seasons were increased significantly compared with non-treated (control) of vegetative growth as indicated by plant height (cm), no. of branches/plant, no. of leaves/plant. These effects were more obvious especially at the treatment of seed coating before sowing by Gaucho insecticide with Integrated nutrients management (G+I.N.) . Data revealed that addition of integrated nutrients with seed coating by Gaucho significantly increased chlorophyll a, b , a + b and carotene contents in cowpea leaves ,as well as, No. of pods plant-1, No. of seed pod-1, 100 seed weight (g) , Crude protein, total carbohydrate and , green pod ,seed and straw yields (ton/fed) . Also, N, P and K contents (kg fed-1)in both green pods, seeds and straw increased significantly with these treatments . The results indicated also that , Aphids represented the most insect pest attacking cowpea with a ratio around 44 % followed by thrips (24%),While whitefly and leaf miner (15%) each . Leafhopper represented the lower pest attack (2%). From the present study, it can be concluded that Imidacloprid (Gaucho 70 WS at 7 g/kg seed) can be coating seed before sowing and using Integrated nutrients management are safe ,cheep ,improve yield quality , protection plant form sucking pests and environmentally-friendly of cowpea . also, This information might be helpful to the vegetables growers.
