MICRONUTRIENT-IMPROVED LIQUID NPK FERTILIZER EFFECT ON GROWTH OF OUR LOCAL CROPS

This study investigates the effects of liquid NPK fertilizer and micronutrient-improved NPK with specific gravity and pH of the stock solution that decreases with dilution was found to be 1.44 and 5.6 (NPK), and 1.65 and 5.4 (micronutrient-improved NPK) respectively on yield and quality of tomato, curry plant, black beans, and fluted pumpkin. The fertilizers were applied at varying concentrations (0-1.0%) twice a week for two months. The study found that Liquid NPK fertilizer increased crop yields by 49.55-52.80% while Micronutrient-improved NPK liquid fertilizer boosted yields by 55.56-69.47% (dried weight). At optimal concentration (0.5%), micronutrient-improved NPK outperformed liquid NPK by 5.63-16.65%. These findings suggest that applying liquid NPK and micronutrient-improved NPK fertilizers can significantly enhance crop yields, quality, and improving national food security when used effectively
