Abstract

During the kharif season of 2020, a field experiment was conducted at the farm of College of Agriculture, Kaul (Kaithal) of CCS Haryana Agricultural University, Hisar. The main objective of the experiment was to examine how a short-duration non-scented rice variety named HKR-48 responded to nitrogen fertilization under two different crop establishment methods. The experiment utilized a randomized block design (RBD) factorial design, with the two establishment methods (direct seeding and transplanting) as the main plot treatments, and six levels of nitrogen (0, 30, 60, 90, 120, and 150 kg/ha) as the sub-plot treatments, with three replications. The results showed that the transplanted crop exhibited significantly higher grain yield and straw yield compared to the direct-seeded crop, with rise of 11.9% and 5% respectively. Although the cost of the transplanted crop was 21.6% higher, the 11% increase in gross returns compensated for it, resulting in equal net returns between the two establishment methods. Increasing the nitrogen dose from the control to 150 kg N/ha significantly improved grain and straw yield, but there were no significant differences between the doses of 120 and 150 kg N/ha. With each additional nitrogen application over the control, there was a gradual increase in gross returns, net returns, and benefit-cost ratio.

Conclusion

The rice variety HKR-48 demonstrated superior performance when transplanted instead of directly seeded. Transplanted crop exhibited a notable increase in grain yield (11.9%) and straw yield (5%) compared to directly seeded crop. Despite the higher cultivation cost associated with transplanting (21.6% higher), the 11% higher gross return offset the difference, resulting in equivalent net returns for both establishment methods. The application of increasing nitrogen doses from the control to 150 kg N/ha had a significant positive impact on grain and straw yield. However, there were no significant differences between the yields obtained with 120 kg N/ha and 150 kg N/ha.
