Effect of Different Levels of Uptake Stimulants on the Yield of Dolichos Bean (Lablab purpureus)

Abstract

This case study investigates the impact of different levels of uptake stimulants on the growth and yield of a leguminous vegetable crop Dolichos bean (Lablab purpureus). The field experiment was conducted during the Rabi season of 2024 at agricultural land of ASPEE Foundation based in Palghar, Maharashtra. The study utilized a Randomized Block Design (RBD) with three replications and seven treatments. Each treatment received drenched well-formulated nutrients in different concentration. The highest pod yield was recorded 2.187 ton/ha with the application of 2 ml P star used per liter of water(T2). For the considered Bauni variety of Dolichos bean, the soil parameters of experimental field are as follows: pH 7.28, Organic Carbon (OC) 0.17%, Electrical Conductivity (EC) 0.84 dS/m, Nitrogen (N) 85.29 kg/ha, Phosphorus (P) 92.19 kg/ha, and Potassium (K) 394.17 kg/ha. This indicates that the application of appropriate treatments using appropriate crop protection equipment with integrated nutrient management (INM) significantly enhanced both growth and yield parameters of Dolichos bean such as number of pods per cluster, pod weight, number of seeds per pod, pod yield per plant and pod Yield (kg/ha).
