Abstract:
A field experiment was carried out at Anbil Dharmalingam Agricultural College and Research Institute, Tamil Nadu Agricultural University, Tiruchirappalli to study the effect of foliar application of nutrients using agricultural drone on growth, yield and quality of green gram. The experiment was laid out on randomized block design with seven treatments and three replications. The treatments consisted two levels of TNAU pulse wonder (1% and 2%), two levels of drone spray fluid requirement (30 and 50 liters ha^-1) along with manual spray (1% and 2% of TNAU pulse wonder with 500 liters ha^-1 spray fluid) and control. Results revealed that application of 2% TNAU pulse wonder with spray fluid of 50 litres ha^-1 significantly recorded taller plants (49.1 cm), higher dry matter production (2311 kg ha^-1), more number of flowers plant^-1 (54.6), number of pods plant^-1 (39.2), higher grain yield (747 kg ha^-1), haulm yield (1684 kg ha^-1), grain protein (23.5%) and grain carbohydrate (57.9%) compared to manual spray and control. Hence, it is concluded that drone spray of 2% TNAU pulse wonder with spray fluid of 50 litres ha^-1 at peak flowering stage could be recommended to improve the yield and quality of green gram.
