Influence of Biozyme on growth and yield performance of rice in rice-rice cropping sequence

Field experiments were conducted to study the effect of Biozyme on growth, total chlorophyll content and the grain yield of rice in rice-rice cropping sequence. Experimental results revealed that the different growth attributes and total leaf chlorophyll content of rice increased with the application of biozyme in combination with chemical fertilizers. When ¼ of the recommended dose of chemical fertilizer was substituted by 20 kg Biozyme ha⁻¹, dry matter yield outweighed the treatment of recommended dose of chemical fertilizer alone. The highest grain yield was obtained from the treatment receiving 60 kg ha⁻¹ of biozyme in two equal splits at 5–7 days after transplanting and at active tillering stage along with the recommended dose of chemical fertilizer. Sole application of biozyme without chemical fertilizer did not bring about better performance.
