Abstract

Plant growth regulators and micronutrients at various combinations [GA3 50ppm + Cycocel 1000ppm + KNO30.2% + Zn 0.3% + Boron 0.1%; GA3 50ppm + Cycocel 2000ppm + KNO3 0.2% + Zn 0.3% + Boron 0.1%; GA3 50ppm + Paclobutrazol 2.5g a.i./tree (soil application) + KNO3 0.2% + Zn 0.3% Boron 0.1%; GA350ppm + Paclobutrazol 3.5g a.i./tree (soil application) + KNO3 0.2% + Zn 0.3% + Boron 0.1%; GA3 50ppm + Paclobutrazol 1000ppm (foliar application) + KNO3 0.2% + Zn 0.3% + Boron 0.1%; and, GA3 50ppm + Paclobutrazol 2000ppm + KNO3 0.2% + Zn 0.3% + Boron 0.1%] were sprayed before flower emergence in acid lime. Minimum days taken to emergence of flower bud (39.57), duration of flowering (24.07), days to 50% fruit set (6.54) and days taken to fruit maturity (145.90) were observed with application of GA3 50ppm + Paclobutrazol 3.5g a.i./tree (soil application) + KNO3 0.2% + Zn 0.3% + Boron 0.1% (T5), whereas, fruit drop (5.92%) was minimum with GA3 50ppm + Cycocel 2000ppm + KNO3 0.2% + Zn 0.3% + Boron 0.1% (T3). Treatment T3 also increased the number of flowers per meter length of shoot (49.65) as well as fruit yield (8.90).
