Performance of dolichos bean (Lablab purpureus L.) varieties as influenced by growth stimulants on quality and economics under southern Telangana conditions

Abstract

An experimental study entitled “Studies on performance of dolichos bean (Lablab purpureus L.) varieties as influenced by growth stimulants under Southern Telangana conditions’’ was carried out during the late rabi season of January to April 2024 at PG research block, College of Horticulture, Rajendranagar, Sri Konda Laxman Telangana Horticultural University. The research aimed to assess the pod quality of dolichos bean with different varieties and growth stimulants. The experiment followed a Factorial Randomized Block Design (FRBD) with two factors: varieties and growth stimulants. Significant difference was observed for all the parameters under study. Results revealed that highest protein content (24.90%) was recorded in the treatment combination of V4G2- CO (GB) 14 + Humic acid @ 1000 ppm and V3G2- Arka Sambhram + Humic acid @ 1000 ppm and highest crude fiber content (12.00%) was recorded in the treatment combination of V4G1- CO (GB) 14 + Triacontanol @ 2 ppm and highest benefit cost ratio (2.75:1) was recorded under treatment combination of V4G2- CO (GB) 14 + Humic acid @ 1000 ppm. These findings suggest that CO (GB) 14 with humic acid @ 1000 ppm is highly effective in improving quality and economics of dolichos bean under Southern Telangana conditions.
