Chickpea is a highly nutritious crop, but soil acidification poses major challenge to its yield in weathered tropical soils. This study evaluated the impact of liming on chickpea growth, yield, nutrient concentration, and use efficiency acidic Oxisols. The experiment was conducted greenhouse using completely randomized design with four lime application rates (0.0, 4.0, 8.0, 12.0 Mg ha−1) achieve different pH base saturation levels, replicates per treatment. Lime had significant quadratic response grain (R2 = 0.92), increasing 125.7%, 308.8%, 252.8% compared control. highest observed at pHCaCl₂ approximately 5.5 (8.0 ha− 1 application). improved components, translocation seeds, efficiency, exchangeable Ca2 + Mg2 +, other key acidity indices. Additionally, it reduced Al3 Al H, saturation. immediate visible effect and/or H toxicity reduction root limiting plant access water nutrients leading low photosynthetic activity flower pod abortion. estimated optimal conditions for maximum were 5.6 70%. Liming found be an effective strategy alleviate enhance growth yield.
