 ABSTRACT

An investigation was conducted to study the effect of different growth regulators viz., NAA and Ethrel along with different bio stimulants viz., Panchakavya, Humic acid, Vermiwash on sex modification, growth and yield of snake gourd (Trichosanthes anguina) at Department of Horticulture,  RVS Padmavathy College of Horticulture, Sempatti. The experiment was laid out in Randomized Block Design with nine treatments with three replications. Treatments (9) consisted of (T₁) - Control, (T₂) – Panchakavya (3%), (T₃) – Humic acid (0.3%), (T₄) – Vermiwash (3%), (T₅)  – NAA (100 ppm),  (T₆)  – NAA (200 ppm), (T₇) – Ethrel (50 ppm), (T₈) – Ethrel (100 ppm) and (T₉) – Ethrel (250 ppm). Based on the observation recorded on the various growths, yield parameters of snake gourd crop; it was found that the growth regulators treatments were significantly superior over the control. The plant growth regulators treatment with 250 ppm ethrel (T₉) registered the highest values of growth characters like vine length and inter nodal distance at different phases of crop growth. The yield parameters viz., fruit length, average fruit weight, number of fruits per vine, yield per vine, number of seeds per fruit were maximum with the application of 250 ppm ethrel (T₉). The application of bio stimulants with 3 % panchakavya (T₂) were significantly increased stem length, fruit length, fruit girth and average fruit weight of snake gourd.

Keywords: Growth regulators, Bio stimulants, Growth, Yield and Chilli.
