Fruits of ‘Balanagar’, the most commonly grown cultivar of sugar apple (Annona squamosa) in India,
come to harvest during the rainy months of September-October. Advancing its fruiting to early summer
would be advantageous for better fruit quality. Since flowering in sugar apple occurs on current season
growth arising naturally after leaf fall during late winter, attempt was made to advance the fruiting season
by defoliating the trees using chemicals, well before the natural leaf fall during December - January. The
chemical defoliants urea (5%, 10% & 15%) and ethrel (2000ppm, 3000ppm & 4000ppm) and bud sprout
promoter KNO3 (5%, 10% and 15%) were sprayed during first week of October for two consecutive
years (2016-17 and 2017-18). Maximum defoliation (97%, 96.5%) was recorded for ethrel @ 4000ppm
during both the years. Early sprouting (26 days, 16.1days) and flower initiation (35 days, 23.03 days)
were recorded in trees sprayed with urea @ 15% for both the years, respectively. Earliest harvest was
from trees treated with urea @ 15% (290 days) and ethrel @ 4000ppm (285 days). Fruit yield per tree
was not affected by any of the treatments. Defoliation with different chemicals significantly influenced
vegetative and reproductive growth of sugar apple cv. Balanagar leading to early fruit harvest by 5-6
weeks
