“…Several rice regions around the world use a prescribing approach based on common models that ignores site-specific crop yields when proposing Nitrogenous fertiliser to comply with the N requirements. (Vennela et al, 2023;Noor, 2017). Effective use of Nitrogenous chemical fertilizers by culture and agriculture can be achieved.…”

In order to investigate how nitrogen and zinc affect the growth and yields of hybrid rice field trial was carried out during the kharif of 2022 at the CRF, Naini Agricultural Institute, SHUATS, Prayagraj (UP). A randomized block design (RBD) was used to set up the experiment, which consisted of three replications and nine different nitrogen and zinc treatment combinations. The results of the experiment showed that the hybrid rice’s growth characteristics were significantly increased by the application of nitrogen (175 kg ha-1) and Zinc (25 kg ha-1), as compared to other nitrogen and zinc combination treatments. Similarly, the above quoted treatment yielded higher gross return (1,24,828 Rs ha-1), higher net return (78,890.18 Rs ha-1) and higher B:C ratio (1.72).
