Yield and quality enhancement of French bean (Phaseolus vulgaris) genotypes by using bio-priming agents

A vast variability in French bean’s genotypes is available in the Uttarakhand which is very crucial as far as concern of farmer’s income. The eco-friendly bio-priming techniques have a potential to enhance the yield and quality of these genotypes. In the present study eight genotypes were collected from different regions of Uttarakhand and used to study the effect of different bio priming on their growth, yield and seed quality parameters. Two bio-priming treatment includes Pseudomonas fluorescence with Trichoderma viride (T1) and Aconitum heterophyllum (T2) along with a control (T0). The findings show that the growth, yield and quality parameters significantly influenced by the treatments applied. The treatment T1 shows significantly higher growth and yield characters than T2 and T0. The minimum days to 50 % field emergence and flowering were recorded with genotype Harshil rajma (V2). The Chakrata rajma (V7) perform best for number of pods per plant, seed yield per plant and seed yield per plot among all other genotypes. Among the seed quality parameter, the highest value of germination per cent (95.16), seedling length (21.81 cm), seedling dry weight (0.80 g), vigour index-I (2075.44) and vigour index-II (76.12) were recorded with treatment T1 and minimum with treatment T0. Among the genotypes, the Chakrata rajma gives the maximum germination per cent (91.55), seedling length (22.01 cm), seedling dry weight (0.83 g), vigour index-I (2015.01) and vigour index-II (75.98) than all other genotypes. Overall, in the present study, it can be concluded that the eco-friendly seed priming treatment of genotype Chakrata rajma with Pseudomonas fluorescence with Trichoderma viride is best to receive sustainable higher economic output in Dehradun region.
