Evaluation of Bush Type French Bean Varieties through Organic Farming in South Chhotanagpur Plateau of Eastern India

Abstract

Background: French bean (Phaseolus vulgaris L.) is an important protein-rich winter vegetable of our country but extensively grown in south Chhotanagpur plateau of Jharkhand during both kharif and rabi seasons. However, indiscriminate uses of agrochemicals lead to production of poor quality pods of the crop due to residual toxicity. Hence, the current study was aimed to evaluate of the crop varieties based on their yield and quality traits expression under organic growing condition.Methods: The present investigation was carried out by adopting five bush type varieties of French bean (V1: Arka Komal, V2: Swarna Priya, V3: HAFB-2, V4: HAFB-4 and V5: Falcon). They were grown independently under two growing conditions viz. organic farming (Oi) where FYM, vermicompost and Shasyagavya were used as organic inputs and absolute control (O0) where no organic input was applied. These varieties were grown with their four replications in each of the experimental situate following RCBD experimental design. Different yield and its attributes and proximate quality traits were studied under both growing conditions for their evaluation.Result: Findings revealed that most of the studied traits were influenced by organic growing condition with significant differences among varieties to pod length, pods per plant, pod weight, green pod yield, ascorbic acid, TSS and protein content. Consequently, the maximum green pod yield (17.55 t ha-1) was estimated in HAFB-4 under organic growing condition as against 7.57 t ha-1 under the absolute control condition. Different proximate quality traits were also expressed independently under different varietal situates but responded better under organic growing condition than its respective absolute control counterpart.
