Abstract

An experiment was conducted at Hajee Mohammad Danesh Science and Technology University, Dinajpur, Bangladesh to investigate the “Effects of N, P, K and S by using biochar for the growth and yield of rice (BRRIdhan 29)”. The experiment was consisted with five treatments i.e., T₁ (Control) Full dosses of N, P, K and S, T₂ (Biochar 10 t ha^-1), T₃ (Biochar 10 t ha^-1+ ½ N, P, K and S), T₄ (Biochar 7.5 t ha^-1+ ½ N, P, K and S) and T₅ (Biochar 5 t ha^-1+ ½ N, P, K and S) with three replications. The highest plant height was observed in T1 control treatment (103.0cm) which was statistically similar to the treatment T₃ (99.93cm). The highest Number of tillers hill^-1was observed in T₁ control treatment (26.10) which was statistically similar to the treatment T₃ (25.17). The highest panicle length (24.89cm) was found in the treatment T₃ which was statistically similar to the treatment T1 (24.75cm). The highest Number of Spikelet hill-1(14.30) was found in the treatment T₃ which was statistically similar to the treatment T₁ (13.87). The highest number of grains panicle-1 (195.4) was found in the treatment T₃ which was statistically similar to the treatment T₁ (192.5). The highest number of filled grains panicle-1 (191.1) was found in the treatment T₃ which was statistically similar to the treatment T₁ (183.3). The highest 1000-grain weight (25.53g) was found in the treatment T₃ which was statistically similar to the treatment T₁ (24.17g).The treatment T₁ recorded the highest grain yield (7.463 t ha^-1) which was statistically similar to the treatments T₃ (7.420 t ha^-1).The treatment T₁ recorded the highest straw yield (9.923 t ha^-1) which was statistically similar to the treatments T₃ (9.867 t ha^-1). The highest biological yield (12.87 t ha^-1) was measured in the treatment T₃ which was similar to the treatment T₁ (Control).
