Abstract:
An experiment was conducted in summer squash to study the effect of four growth regulators viz., Naphthalene acetic acid (NAA), Gibberellic acid (GA₃), ethrel and Malic hydrazide (MH) for yield characters and quality traits in summers squash. Foliage application of NAA @ 100 ppm was found beneficial for yield per plant (Kg) and fruit yield per hectare (t/ha). With respect to quality parameters, NAA @ 100 ppm significantly recorded highest values for moisture content, total soluble solids of summer squash. Whereas, MH @ 200 ppm lowered the titrable acidity, increased ascorbic acid content, increased total sugars and reducing sugars. Significant differences were observed with the use of growth regulators on yield and quality traits of summer squash.
