Effect of Phosphorus and Boron on Growth Yield and Quality of French bean Phaseolus vulgaris L va Azad Rajmah 1

Abstract

French bean (Phaseolus vulgaris L.) is a globally significant leguminous vegetable with a short growth duration, known by various synonyms such as kidney bean, common bean, snap bean, and more. It originated in Middle America and has two primary Center of origin, Mexico and Central America. French beans are rich in nutrients, including protein, carbohydrates, fat, calcium, phosphorus, iron, and vitamins. This study was conducted during the rabi seasons of 2021-22 and 2022-23 at vegetable farm CSAUandT Kanpur Uttar Pradesh, India, to investigate the impact of phosphorus and boron fertilization on French bean growth and yield. The experiment laid in Factorial RBD included 12 treatments involving 4 combinations of phosphorus and 3 combinations of boron. The results revealed significant effects of phosphorus and boron treatments on various growth parameters of French bean. Phosphorus treatments, particularly P3 (35 kg/ha), consistently produced taller plants with more branches and pods. Similarly, boron treatments, especially B2 (1.5 kg/ha), led to improved plant height and pod production. The combination of P3B2 consistently resulted in the best performance in terms of plant height, branches, and pod count. In addition to growth parameters, the study also assessed yield parameters. Phosphorus and boron treatments influenced pod length, width, seeds per pod, test weight, average fresh pod weight, and average seed weight. P3 and B2 treatments consistently yielded longer pods, wider pods, more seeds per pod, higher test weights, and heavier pods and quality related parameters, including, protein content, and amino acid composition (methionine, leucine, isoleucine, histidine, and tryptophan), were significantly influenced by the treatments. P3 and B2 consistently resulted in higher values newlinefor these parameters, with the interaction of P3B2 producing the most favourable outcomes. Overall, the study highlights the importance of phosphorus and boron fertilization in enhancing the growth and yield of French bean. The combin
