EFFECT OF ORGANIC AMENDMENTS ON AGRONOMIC PERFORMANCE OF GREEN PEA (PISUM SATIVUM)

Abstract

A field experiment was conducted to evaluate the effects of various organic amendments, including farm manure (FM), agro-waste compost (AC) , sewage sludge (SS) and poultry manure (PM), as well as synthetic fertilizer, on the agronomic performance of green pea (Pisum sativum). The study assessed plant growth, yield attributes and pod yield under different nutrient management treatments. The results demonstrated that all organic amendments significantly improved plant height, pod number, pod length and grain count per pod compared to the control. PM (5 t/ha) recorded the highest plant height (82.4 cm) and pod yield (8.32 t/ha), significantly outperforming the control (3.42 t/ha) and synthetic fertilizer (7.21 t/ha). SS (5 t/ha) showed highest pod yield (8.10 t/ha), followed by FM (7.45 t/ha) and agro-waste compost (7.22 t/ha). Statistical test revealed that PM and SS were superior (p < 0.05) to synthetic fertilizer in terms of yield and other agronomic attributes. These outcomes highlight the potential of organic alterations in enhancing green pea production.
