Abstract

On the subject of the economic sustainability of rice (Oryza sativa L) types to various levels of nitrogen under wetland rice agriculture, a field experiment was carried out in Champhai in 2019 and 2020. With 'CO-52' at 80 kg N/ha, plant height and dry matter output were at their maximum. Panicles/m2, full grains/panicle, production of grain and straw (4.50 tons/ha), as well as the uptake of nitrogen by grain and straw, were all noticeably greater with "CO-52". Rising nitrogen levels increased the number of panicles/m2, the number of filled grains per panicle, the yield of grains and straw, and the amount of nitrogen taken up by grains and straw only up to 80 kg N/ha. The maximum grain production and economics were observed with "CO-52" at 80 kg N/ha, and it was discovered to be the ideal combination for wetland rice agriculture. Varieties and nitrogen levels interacted considerably.

Conclusion

The study's conclusions showed that the variety "CO-52" with a 75 kg N/ha treatment was ideal for rice grown in wetland conditions since it promoted wetland rice development, increased productivity, and boosted profitability. Among the three different varieties CO-52, CAU-R1 and "Gomati"—with the three different nitrogen concentrations, namely 25, 50, 75, and 100 kg/ha.
