This study investigated the effect of organic fertilization levels on the growth and productivity of chickpea (Cicer arietinum L.) in the Al-Bayda region, Al-Jabal Al-Akhdar, Libya, during the 2025 growing season. The experiment was conducted using a randomized complete block design (RCBD) with four replications. The treatments consisted of three levels of organic fertilizer: a control (0), 15 tons/hectare, and 25 tons/hectare. The study aimed to determine the optimal fertilization rate to enhance crop growth and yield. Results showed significant differences (P<0.05) between treatments. The 25 tons/hectare treatment consistently outperformed others, recording the highest plant height (37.80 cm), seed count per plant (45.11), seed weight per plant (33.11 g), biological yield (3225.44 kg/hectare), grain yield (1276.44 kg/hectare), and harvest index (39.57%). Conversely, the 15 tons/hectare treatment produced the highest straw yield (2006.10 kg/hectare). It is concluded that the 25 tons/hectare application is the most effective level for maximizing key agronomic traits and overall productivity under the specified environmental conditions.
