Abstract

An experiment was conducted during 2021 to 2023 at Horticultural Research Centre of Sardar Vallabhbhai Patel University of Agriculture and Technology, Meerut, U.P., to investigate the impact of biofertilizers on the vegetative characteristics of five pear varieties: Babugosha, Punjab Beauty, Punjab Gold, Punjab Nectar, and Gola. These varieties were subjected to varying doses of bio fertilizers, including different combinations of Azotobacter, Trichoderma, PSB, and Vermicompost. Eight distinct treatments were formulated by combining these biofertilizer components. Plants are associated with rhizospheric microbes, which have the ability to promote crop growth and stress tolerance, enhance plant nutrition, and improve vegetation propagation. Thus, the formulation and application of biofertilizers containing these beneficial microbes is a promising approach to improve horticultural crops. Out of the 8 treatments applied, the findings of the study revealed that among the different biofertilizer applications, Treatment 8 (T8), consisting of N-100% + P-100% + Azotobacter (100g) + PSB (100g) + Trichoderma (50g) + vermicompost at 3kg, exhibited favourable interactions with variety 5 (V5), known as the Gola variety. This treatment resulted in the highest plant height (6.42 and 6.50 cm), maximum number of lateral branches (25.69 and 26.03) per plant, greatest stem girth (31.59 and 31.98 mm), and largest canopy spread (3.66 and 3.69 m) over both years of the experiment. These combination of N-100% + P-100% + Azotobacter (100g) + PSB (100g) + Trichoderma (50g) + vermicompost at 3kg proved to be the most effective in promoting the vegetative growth of the trees, specifically enhancing parameters such as plant height, number of lateral branches, plant canopy size, and stem girth in the case of the Gola variety.

Conclusion

In conclusion, the combination of T8 treatment (N-100%+P-100%+Azotobacter 100g + PSB 100g + Trichoderma 50g + vermicompost at 3kg) demonstrates remarkable performance across various aspects of vegetative growth. Specifically, the V5 Gola variety exhibits a strong compatibility with the integrated use of this biofertilizer composition comprising N-100%+P-100%+Azotobacter 100g + PSB 100g + Trichoderma 50g + vermicompost at 3kg, particularly within the context of the western Uttar Pradesh region. It is noteworthy that the Gola variety, in conjunction with the aforementioned biofertilizer blend, showcases exceptional potential. Therefore, the application of N-100%+P-100%+Azotobacter 100g + PSB 100g + Trichoderma 50g + vermicompost at 3kg is recommended for optimal outcomes in the cultivation of the Gola variety, emphasizing its superior performance when utilized in tandem with this biofertilizer combination.
