EFFECT OF COW DUNG ON LEAFE LENGTH AND STEM HEIGHT OF SOYA BEANS (GLYCINE MAX)
Abstract
The study investigated the effect of varying levels of cow dung on the growth parameters of soybean (Glycine max), focusing on leaf length and stem height. The experiment was conducted using four treatments: T₀ (0 g cow dung), T₁ (2 g), T₂ (4 g), and T₃ (6 g), applied to separate plots under controlled environmental conditions. Measurements of leaf length and stem height were taken weekly over a four-week growth period. Results indicated a significant increase in both parameters with increasing cow dung application, with T₃ producing the highest mean leaf length and stem height, followed by T₂ and T₁, while T₀ recorded the lowest values. The enhancement in growth attributes was attributed to improved soil fertility and nutrient availability provided by cow dung, particularly nitrogen, phosphorus, and potassium, which are essential for vegetative growth. The findings suggest that moderate to high rates of cow dung can be an effective organic amendment for optimizing soybean growth. It is recommended that 6 g of cow dung per plant be applied for optimal performance in similar agro-ecological zones.
