Abstract:
The present investigation was carried out under Allahabad agro-climatic conditions at the experimental field of the department of Horticulture, Naini Agricultural Institute, Sam Higginbottom University of Agriculture Technology & Sciences, Allahabad (U.P.) entitled “Effect of different pruning levels and foliar application of PGRs on quality fruit production of Phalsa (Grewia asiatica L.). The pruning (3 °Cm, 6 °Cm and 9 °Cm) was done from old shoots of phalsa plant with the help of looper by manual labour and PGRs namely NAA (150 and 200 ppm) and GA₃ (100 and 200 ppm) were applied as foliar spray after new shoots growth. The results revealed that treatment T₆ (90 cm + GA₃ @ 200 ppm + NAA @ 200 ppm) was recorded significantly the maximum number of sprouted shoots per canes (30.30) at 120 DAP, total number of flowers per plant (2927.41) at 75 days after pruning, Number of fruiting nodes per shoots (27.72) at 120 days, fresh weight of 10 fruits (9.57 g), dry weight of 10 fruits (2.40g), fruit yield per bush (4.78 kg), fruit yield per hectare (6.94t/ha), total soluble solids (22.82°Brix), total sugar (12.33%), and titratable acidity (2.78%) and minimum days taken to first flower (61.24). The minimum number of sprouted shoots per canes (14.11) at 120 DAP, total number of flowering per plant (1633.34), number of fruiting nodes per shoots (14.52), fresh weight of 10 fruits (6.63), dry weight of 10 fruits (1.27), yield per bush (1.45 kg), fruit yield (2.06 t/ha), total sugar (8.36%), TSS ^°brix (15.37) and the maximum number of days taken to first flowering (75.37) were recorded with treatment T₀.
