Abstract
Two factors of different levels of pruning intensities, i.e. 40cm, 60cm and 80cm from ground level, with foliar feeding of NAA concentrations, i.e. 100ppm, 150ppm and 200ppm, were tried to investigate their effects on growth, yield and quality attributes of phalsa (Grewia asiatica L.)cv. Sharbati, conducted at Horticulture Garden, Department of Fruit Science, C.S.A.U.A.T., Kanpur, (U.P). The results showed significant effects on the maximum number of shoots per plant(5.62), shoot length(140.69 cm), number of fruits/node (10.90), length of fruit (2.27 cm), 100 fruitweight (60.55g), yield per plant(3.65kg), juice content(54.51%), T.S.S. (16.660B), reducing sugars (9.20%), non-reducing sugars (4.25%), total sugars (13.45%), titratable acidity(1.84%) and ascorbic acid (35.51 mg) per100 g fruit pulp were observed on spray of NAA @ 200 ppm with 40 cm pruning intensity from ground level. Hence concluded from the results in phalsa plants cv. Sharbati,spray of 200 ppm NAA with pruning at 40 cm from ground level was most effective for improving growth, yield and quality attributes.
