Abstract

A field experiment was conducted during kharif 2020 at Central Crop Research Farm, Department of Agronomy, SHUATS, Prayagraj (U.P.). The effect of biofertilizers and organic manures on growth and yield of organic rice, the soil of experimental plot was sandy loam in texture, nearly neutral in soil reaction (PH 7.1), low in organic carbon (0.28%), available N (225 kg/ha), available p (19.50 kg/ha), The treatment consists of Azotobacter (25 g/kg), Azospirillum (25 g/kg), Azotobacter + Azospirillum (12.5 + 12.5 g/kg) as seed inoculants and Farm Yard Manure (12 t/ha), Poultry Manure (4 t/ha) and Vermicompost (4 t/ha), whose effect was observed in Rice. The experiment was laid out in Randomized Block Design (RBD) there are 10 treatments which are replicated thrice. The result showed that the growth parameters viz. plant height (75.83 cm) at 100 DAT, number of tillers per hill (12.07) at 100 DAT and dry weight (25.03 g) at 100 DAT was recorded superior with the application of Azotobacter (12

Keywords

Conclusion

The treatment with Azotobacter + Azospirillum +12 t/ha of FYM was shown to be more productive (4.77t/ha) and economically (77518 INR/ha) feasible after one season of testing. The conclusion drawn based on the one season data only which require further conformation for recommendation.
