EFFECT OF DIFFERENT RATE OF ORGANIC FERTILIZER APPLICATION ON EARLY GROWTH OF TAMARINDUS INDICA L.
Abstract
This study examines the effects of varying rates of organic fertilizer application on the early growth of Tamarindus indica L. seedlings, focusing on key morphological traits such as survival, height, girth, and leaf production. Organic manure, specifically poultry droppings, was applied at doses of 2 g, 4 g, and 6 g to evaluate their impact on seedling development over an 8-week period. The results revealed no negative effects on seedling survival across all treatments. Height growth was not significantly different after 2 weeks but showed a positive trend with the 6 g application after 8 weeks, with a mean height of 14.70±3.68 cm. Girth growth did not exhibit significant differences among treatments, but the 6g poultry manure dose had a notable effect on diameter increment. The number of leaves showed significant differences (p < 0.01), with the highest mean leaf count of 12.70±3.68 observed at the 6g dose after 8 weeks, while the control group showed the lowest leaf production. These findings suggest that poultry manure, particularly at the 6 g rate, enhances the early growth of Tamarindus indica L., supporting improved height, leaf number, and overall diameter
