Intercomparision of Drone and Conventional Spraying Nutrients on Crop Growth and Yield in Black Gram

An experiment was conducted to reveal the effect of drone spraying of foliar nutrients on the crop growth and yield in black gram at Agricultural Research station, Bhavanisagar in Random block design with 12 treatments with 3 replications. The biometric parameters viz., plant height, leaf area, dry matter production and yield parameters viz., number of pods plant-1, haulm yield and grain yield were influenced more by drone spaying treatments than conventional method of knapsack spraying. The results revealed that Fuel operated drone spray of 2% pulse wonder with spray fluid of 75 L ha-1 using atomizer nozzle recorded the highest growth and yield attributes values. The treatment which registered the highest grain and haulm yield of 784 and 1525 kg ha-1 and it was performed better than as compared to foliar spraying of all 19 solution with fuel operated drone the and the lowest yield was noticed in control. From this study it is concluded that fuel operated drone spray of 2% pulse wonder using the atomizer nozzle with spray fluid of 75 L ha-1 is adopted to enhance the growth and grain yield of black gram.
