Performance of Promising French Bean (Phaseolus vulgaris L.) Varieties for Growth and Yield Performance under different Agro-Climatic Conditions of Assam

AbstractA field experiment was conducted to assess the yield performance of four French bean (Phaseolus vulgaris L.) varieties, namely Arka Komal, Arka Sharath, Arka Arjun, and Syngenta Serengeti, at Jorhat district under the supervision of Krishi Vigyan Kendra, Jorhat, during the 2023-2024 and 2024-2025 growing seasons. The experiment was laid out in randomized block design with three replications across five locations. Significant differences were observed among the varieties for growth and yield traits. Arka Sharath recorded the highest fresh pod yield per plant (234.25 g) and maximum yield (163.97 q/ha), followed by Arka Arjun (145.36 q/ha) and Arka Komal (140.91 q/ha), surpassing the control (140.36 q/ha). Arka Sharath also produced the longest pods (15.23 cm) and highest pod weight (9.70 g). Although Syngenta Serengeti produced the maximum pods per plant (44.56), Arka Sharath compensated with heavier pods, resulting in higher yield and profitability. Economic analysis revealed that Arka Sharath gave the maximum net return (?2,11,940 ha-1) with a benefit-cost ratio of 2.82, followed by Arka Arjun (2.50) and Arka Komal (2.42), all higher than the control (2.28). The study concluded that Arka Sharath was the most suitable variety for commercial cultivation in Jorhat district to enhance productivity and profitability.
