An experiment was conducted during 2010-11 to find out the “Response of foliar feeding of Gluconate and EDTA chelated plant nutrients on growth, yield and absorption of nutrients by leaves in Bt-cotton under rainfed condition” at Department of Soil Science and Agril Chemistry, VNMKV, Parbhani. The experiment includes seventeen treatment includes viz., T1-Zn Gluconate, T2-Mn Gluconate, T3-Cu gluconate, T4- Fe Gluconate,T5- Ca Gluconate, T6- Mg Gluconate, T7- combination of all Gluconate , T8- Zn-EDTA,T9- Mn EDTA, T10- Cu EDTA, T11-Fe EDTA , T12 – Ca EDTA, T13- Mg EDTA, T14- combination of all EDTA, T15- Govt. grade II, T16- Water spray and T17- Control replicated twice. The treatments were fertilized with 120:60:60 N, P2O5 and K2O Kg ha-1. Foliar spray of gluconate and EDTA chelated nutrients were given at 75 DAS. Biometric observations such as height of plant, number of leaves, leaf area and yield attributes such as number of bolls per plant, weight of boll and yield were taken at 80,100 and 120 DAS. Immediately after 3, 6, 12, 24, 36 and 48 hours of sprays nutrient concentration was determined by adopting suitable method. Five leaves from each treated plants were collected to find out the absorption time of plant nutrients. The result revealed that foliar feeding of Zn gluconate showed maximum growth and yield. The foliar feeding of Zn through Zn Gluconate had maximum absorption and it was between 3-6 hours. Iron concentration was more after 6 hours due to application of Fe Gluconate, followed by Fe EDTA as compaired to control. While the application of manganese Gluconate showed maximum absorption of manganese by Bt. Cotton plant. Further application of Cu Gluconate recorded more absorption of Cu after 6 hours of spray over control, water spray and Government grade II.
