Azzola as a novel bio-fertilizer and inorganic nitrogen on Marketable yield and quality response of tomato fruits

Résumé

Abstract Many people are concerned about the environment and believe that organic products are healthier than conventional ones, so there is a growing demand for organic vegetable products. According to studies, organically grown tomato fruits contain higher levels of carotenoids, polyphenols, and antioxidants than conventionally grown tomatoes. Enhancing tomato marketable yield and quality through the application of optimal organic and inorganic fertilizers is a crucial agronomic practice. The purpose of this study was to compare the effects of organic and inorganic fertilization on the marketable yield and quality characteristics of tomato fruits. A pot experiment with three replications and two fertilization treatments with four levels each (nitrogen as an inorganic fertilizer and Azzola as an organic fertilizer) was set up in a completely randomized design. The findings revealed that nitrogen and Azzola biofertilizer had a significant effect on fruit diameter and all quality parameters. The interaction effects of Azzola and nitrogen on cluster number per plant, flower number per cluster, fruit set percentage, and fruit number per cluster, and marketability were significant. Consequently, tomato growers are advised to apply 1.5 g of nitrogen and 75 g of Azzola.
