Abstract:
The present investigation entitled “Effect of plant growth regulators and chemicals on flower regulation during hasta bahar in acid lime cv. Balaji” was carried out in Horticultural Research Station, Anantharajupeta, Annamayya district during September, 2022 - May, 2023. The experiment was laid out in a randomized block design with three replications and nine treatments. Among the treatments maximum number of flowers per shoot (16.64) was reported in T₂ (Cycocel @ 1000 ppm in September + Thiourea @ 1% in October). Application of Cycocel @ 1000 ppm in September + Potassium Nitrate @ 1% in October + GA₃ @ 50 ppm in December resulted in maximum initial fruit set (64.69%), fruit retention at harvest per shoot (51.81%), number of fruits per tree (356.95) and fruit yield per tree (18.33 kg/tree) while minimum number of days for flower initiation (41.45) and days for fruit maturity from flower initiation (152.67). However application of Cycocel @ 1000 ppm in September + 2,4-D @ 10 ppm in December resulted in minimum fruit drop percentage (48.19%).
