Summary
The common bean ( Phaseolus vulgaris L.) is a vital legume crop for advancing global food security, climate‐resilient agriculture, and soil fertility. However, the yields of Western Himalayan common bean remain low due to nutrient‐deficient soils, traditional farming practices, and a lack of improved inputs. This study evaluated the effect of Pseudomonas jesenii MP1 and Pseudomonas palleroniana N26 for enhancing common bean yield and nutrition under farmer‐managed conditions in Uttarakhand. Both bioinoculants significantly increased crop yield across the years and locations, with improvements ranging from 4.84% to 25.05% compared to the control (untreated). An increase of 22.70% in crop yield was recorded with the N26 treatment, while the highest improvement (25.05%) was recorde
Regional applicability
This study was conducted in Uttarakhand, India, and addresses low-input, high-altitude legume production in the Western Himalayas—conditions not directly applicable to United Kingdom temperate arable or horticultural systems. However, the general approach of using native Pseudomonas strains to improve bean yield and nutrition in marginal soils may offer insights for organic or low-input UK horticulture, particularly if adapted Pseudomonas strains could be validated under British climatic and soil conditions.
Key measures
Crop yield (%), seed physical traits (weight, length, width, thickness), total carbohydrate content, protein content, antioxidant activity (DPPH assay), methionine content, linear mixed model analysis of treatment effects, principal component analysis, Pearson's correlation coefficients
Outcomes reported
The study measured common bean yield, seed physical traits (weight, length, width, thickness), and nutritional composition including total carbohydrates, protein, antioxidant activity, and methionine content under farmer-managed conditions in Uttarakhand. Both Pseudomonas bioinoculants significantly increased crop yield and enhanced various nutritional parameters compared to untreated controls.
