Effect of organic and inorganic fertilizers on germination and leaf yield of basil (Ocimum basilicum)

Abstract

A study was conducted to determine the effects of organic and inorganic fertilizers on the growth and yield traits of basil (Ocimum basilicum L.). The investigation was conducted in the early summer of 2025 and involved 11 treatments that contained both inorganic fertilizers and organic manures, either in combination or alone, in a completely randomized design with three replicates. The results of this study demonstrated that both organic manures and inorganic fertilizers had a major effect on the germination, growth, and yield metrics of basil. The treatment that included 75% RDF and 25% vermicompost resulted in increased seed germination (16.96%), 50% seed germination (22.73%), germination% (91.83), survival% (89.55%), plant height (65.10 cm), number of branches (110.57), number of leaves (356.53), fresh herbage yield (282.06), and dry herbage yield (51.44), followed by 75% RDF and 25% poultry manure.
