Abstract

Mango, known as the "King of Fruits," is the most important fruit crop in India. However, residual toxicity from agro-chemicals presents a significant challenge for capturing international markets. By adopting organic farming we can go for the production of safe and high-quality mangoes. To explore this approach, a study was undertaken to evaluate the response of mango trees to a combination of bio-fertilizers and green manure-based organic treatments. The study, titled "Effect of Green Manures and Bio-Fertilizers on Quality and Yield of Mango (Mangifera indica L.) cv. Amrapali," was carried out during the years 2018-19 and 2019-20 at the Horticultural Research Farm and P.G. Laboratory of the Department of Horticulture at B.A. College of Agriculture, Anand Agricultural University, Anand (Gujarat). The results showed that the treatment of double green manuring of sunhemp and 10ml of Bio NPK consortium per tree produced the best quality mangoes. This treatment resulted in the highest levels of total soluble solids (23.05 oBrix), reducing sugar (8.01%), total sugar (19.98%), ascorbic acid content (43.73 mg/100g pulp) and lower titrable acidity (0.175%). Additionally, this treatment led to the maximum fruit yield with the greatest number of fruits per tree (268.98), highest fruit weight (192.39 g), maximum fruit yield (52.86 kg/tree or 14.64 t/ha) and graded fruit yield A, B, and C kg per tree. Overall, the study demonstrates the efficacy of green manuring and bio-fertilizers as an organic approach to enhance mango quality and yield.

Conclusion

The findings of the present investigation suggest that the application of double green manuring of sunhemp in the canopy area along with the use of 10 ml Bio NPK consortium per tree can significantly improve quality parameters such as TSS, acidity, total sugar, reducing sugar, and ascorbic acid. Moreover, it can enhance yield contributing parameters such as the number of fruits per tree, average fruit weight, fruit yield in kg per tree, and estimated fruit yield in tonnes per hectare in mango cv. Amrapali. These results provide useful information for farmers and researchers who are interested in adopting organic farming practices to achieve better quality and yield in fruit crops.
