Effect of Crop Establishment Methods and Organic Weed Management on Nutrient Uptake, Soil Fertility, and Yield of Aromatic Rice (Oryza sativa L)

A field experiment was carried out during Kharif, 2019 in an organic block of Instructional-cum-Research farm Assam Agricultural University, Jorhat, Assam, India to evaluate the effects systems rice establishment and weed management practices on yield, nutrient uptake, soil fertility aromatic variety Kola joha. The laid a split-plot design with main plot subplot. transplanting method resulted significantly higher grain yield 18.17 quintal/hectare (q ha-1) uptake over direct seeded method. Among practices, highest (21.95 q were recorded hand weeding at 20 40 DAT/DAS which followed by intercropping dhaincha incorporation DAT/ DAS (16.90 ha-1). available N content (260.86 Kg post-harvest DAT whereas P2O5 K2O contents DAT/DAS.
