Abstract:

A field experiment was conducted to study the effect of plant growth regulators and chemical on growth, flowering and yield of hasta bahar acid lime (Citrus aurantifolia Swingle). The experiment was laid out in split plot design with two main plot treatments and nine sub-plot treatments and three replications. The study revealed that, the application of GA3 @ 50 ppm in June + Cycocel @ 1000 ppm in September + KNO3 @ 2 % in October showed superior performance in regard to number of flowers per shoot (8.18), number of fruits per tree (382.50), initial fruit set (54.74) and fruit retention (39.73), yield (4.13) and percentage increase in yield over control (52.43). GA3 @ 50 ppm in June recorded highest increase in plant height, canopy spreads, canopy volume, shoot length and also resulted in highest days taken to flowering. However, KNO3 @ 2 % in October induced earliest flowering in acid lime.
