Abstract
Abstract Field studies were conducted over two years to determine changes in soil biochemical properties and rain-fed upland rice yield as influenced by biochar amendment. Treatments consisted of incorporation of rice husk biochar at different rates (B1 = 0, B2 = 3 t ha−1, B3 = 6 t ha−1, and B4 = 12 t ha−1). Soil enzymes viz invertase, alkaline phosphatase, urease, and catalase, were significantly (P ˂ 0.05) higher under the highest application rate of biochar (12 t ha−1). Higher rates of enzyme activities were recorded within the top soil layer (0–0.1 m). Soil organic carbon, available nitrogen, Bray 1 phosphorus, total nitrogen and soil moisture content were significantly (P ˂ 0.05) increased upon the application of biochar at a rate of 12 t ha−1 in the top 0–0.1 m layer. Similarly, application of biochar at 12 t ha−1 significantly (P
