Productivity of Rice-toria-greengram Cropping Sequence as Influenced by Integrated Nutrient Management Practices and Rice Establishment Techniques B Baro K Pathak BK Medhi K Choudhury M Saikia R Das<p><strong>Aim:</strong> To study the effect of integrated nutrient management practices on performance and productivity of crops in rice-toria - greengram cropping sequence under different rice establishment techniques.</p><p><strong>Methodology:</strong> Two years field experiment was conducted with two different establishment techniques of rice viz., Transplanted rice (M1) and Direct seeded rice (M2) in main plot and five different nutrient management practices viz., Control(N1), 100% RDF (N2), 50% RDN as inorganic + 50% RDN as vermi-compost + bio-fertilizer (N3), 75% RDN as inorganic + 25% RDN as vermi-compost + bio-fertilizer (N4) and 100% N as vermi-compost + bio-fertilizer (N5) in sub-plots. Data were collected and analysed following the standard procedures. The growth and yield attributing parameters in rice-toria-greengram cropping sequence were studied.</p><p><strong>Results:</strong> Transplanted rice significantly affected the plant height, grain and straw yield of rice in rice-toria-greengram cropping sequence. Significantly, higher plant height (112.94 cm and 113.97cm), grain yield (45.18q/ha and 45.91 q/ha) and straw yield (64.35 q/ha and 65.17q/ha) was recorded in transplanted rice during both the years, respectively. In terms of nutrient management, the treatment 50% RDN as inorganic + 50% RDN as vermi-compost + bio-fertilizer significantly affected the growth and yield of rice and greengram. In rice, the highest grain yield (50.25q/ha and 51.41 q/ha), and seed yield (9.49 q/ha and 10.06 q/ha) in greengram was recorded under 50% RDN as inorganic + 50% RDN as vermi-compost + bio-fertilizer during both the years. In toria, nutrient management with 75% RDN as inorganic + 25% RDN as vermi-compost + bio-fertilizer recorded the highest seed yield (6.49q/ha and 6.82q/ha) and stover yield(17.14 q/ha and17.74 q/ha)in both the years.</p><p><strong>Interpretation:</strong> Based on the findings of the two years study, it was found that the integrated nutrient management package through application of 50% RDN as inorganic + 50% RDN as vermi-compost + bio-fertilizer and 75 % RDN as inorganic + 25% RDN as vermi-compost + bio-fertilizer registered the best performance in terms of growth and yield in rice, greengram and in toria. Thus, integrated nutrient management package through application of 50% RDN as inorganic + 50% RDN as vermi-compost + bio-fertilizer with transplanted technique of rice establishment under rice-toria-greengram cropping sequence can be suggested for enhancing productivity of rice, toria and greengram.</p> Open Journal of Environmental Biology - Peertechz Publications 2025-08-08 Research Article https://doi.org/10.17352/ojeb.000051 en Copyright © B Baro et al.
