Abstract:
The present investigation entitled “Effect of varieties, dates of sowing, growth regulators and their interaction on yield and quality of Dolichos Bean (Lablab purpureus L.) during offseason under coastal Andhra Pradesh conditions” was carried out during summer at Horticultural Research Station, Ambajipeta, East Godavari District of Andhra Pradesh. The experiment was laid out with 36 different treatment combinations in a Factorial Randomized Block Design (FRBD) each replicated thrice in open field. The experiment was carried out with four varieties viz., Arka Jay, Arka Amog, Arka Sambhram and Arka Sowmya with three different dates of sowing viz., December 15^th, January1^st and January15^th with foliar spray of growth regulators viz., NAA 25 ppm, Triacontanol 2 ppm and control. The data were recorded on yield and quality parameters and the data were statistically analyzed based on ANOVA. Arka Sowmya recorded significantly highest pod yield per plant (237.72 g) and Arka Jay recorded highest shelling percentage of fresh pod (35.63%). January 1^st sown crop recorded significantly the highest pod yield (232.68 g) and highest shelling percentage of fresh pod (35.18%). Triacontanol @ 2 pm foliar spray recorded significantly the highest pod yield (226.30 g) and highest shelling percentage of fresh pod (36.44%). However highest protein and fibre content was observed with NAA @ 25 ppm spray 15.35% and 33.69% respectively. Arka Sowmya sown on January 1^st in combination with Triacontanol 2 ppmspray (V₄S₂G₂) recorded the highest pod yield of 293.90 g. Arka Jay sown on January 1^st without spray (V₁S₂G₃) recorded the lowest green pod yield per plant (143.74 g).
