Abstract:

The present investigation entitled “Effect of varieties, dates of sowing, growth regulators on growth and yield of Dolichos Bean (Lablab purpureus L.) during offseason under coastal Andhra Pradesh conditions was carried out during summer 2014-15 and 2015-16 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 15th, January1st and January15th with foliar spray of growth regulators viz., NAA 25 ppm, Triacontanol 2 ppm and control. The data were recorded on various growth, and yield parameters and the data were statistically analyzed based on ANOVA. Arka Sowmya (V4) recorded significantly highest leaf area (1113.8 cm2) number of buds per node (5.07), pod weight (4.54 g) and highest pod yield per ha (197.36 q) in open field. Arka Jay took least number of days for 50 per cent flowering (41.62 days). January 1st sown crop recorded significantly the highest plant height (67.77cm), leaf area (1113.8 cm2) number of buds per node (4.81) and highest pod yield per ha (204.43q) and also took less number of days for 50 per cent flowering (41.02) in open field . Triacontanol @2 pm foliar spray recorded significantly the highest plant height (68.4 cm), leaf area (1077.0 cm2), number of buds per node (4.87) and pod yield(190.1q/ha) and took least number of days to 50% flowering (41.64 days). Arka Sowmya recorded the highest pod yield per hectare (262.12q) when sown on January 1st and sprayed with Triacontanol 2 ppm foliar spray (V4S2G2).
