Abstract:

Field experiment was conducted to evaluate the performance of weed management and biofertilizer on productivity of transplanted rice variety ‘MTU-7029 (Swarna)’. Experiment was laid out in factorial randomized block design with 24 treatments, comprising of twelve weed management practices and two nutrient management practices viz. No biofertilizer and biofertilizer (Azotobacter + PSB), replicated thrice. All the herbicidal treatment resulted in significant reduction in total weed dry weight and weed population than weedy check. The higher grain and straw yield was recorded in the plot where pendimethalin 0.75 kg/ha fb bispyribac-sodium 50 g/ha was applied. In case of grain yield, it was statistically at par with application of pendimethalin 0.75 kg/ha fb bispyribac-sodium 25 g/ha and weed free check during both the years. The highest net returns and benefit-cost ratio was realized under the application of pendimethalin 0.75 kg/ha fb bispyribac-sodium 25 g/ha and also in biofertilizer applied plot.
