Effect of rate of biofertilizers on growth and development of spinach (Spinacia Oleracea L.)
Abstract
This research delves into the utilization of biofertilizers as a sustainable substitute for conventional chemical fertilizers, offering multifaceted advantages for soil fertility, plant vitality, and ecological equilibrium. The study investigates the effects of different application rates of biofertilizers on various growth parameters, nutrient assimilation efficiency, yield components, and physiological responses in spinach cultivation. A series of experimental trials were conducted to evaluate the impacts of biofertilizer treatments, comprising vermicompost, Azotobacter, and phosphate-solubilizing bacteria (PSB), on spinach plants. The results indicate that combined application of biofertilizers significantly enhances key parameters including plant height, leaf area, shoot biomass, root biomass, nutrient assimilation efficiency, yield components, and physiological responses compared to conventional fertilizer practices and control groups. Correlation and regression analyses reveal strong positive relationships between levels of biofertilizer application and various growth metrics, nutrient assimilation efficiency, yield components, and physiological responses. Furthermore, ANOVA results confirm the statistical significance of differences among treatment groups, highlighting the efficacy of biofertilizers in promoting spinach growth and productivity. Economic evaluations suggest that despite higher initial costs, the use of biofertilizers results in increased spinach yields, making it a financially viable and environmentally sustainable alternative to traditional fertilization methods.
