Abstract

The Bundelkhand region of India falls under a semi-arid climate and is not typical for rice cultivation. Rice cultivation has been expanding in heavy-textured soils with limited water irrigation. The experiment was carried out with a split-plot design with main factor transplanting methods (line and random transplanting) and subfactor six nitrogenmanagement options (omissionN (ON), farmers’fertilizer practice (FFP), state fertilizer recommendation (SFR), IRRI Leaf Color Chart (LCC), Panjab Agriculture University (PAU-LCC) and Rice Crop Manager (RCM) replicated thrice on heavy-textured soil at the student’s research farm, Banda University of Agriculture & Technology, Banda during the wet season of 2020 and 2021. IRRI LCC and PAU LCC also had significantly higher growth parameters and yield attributes for augmenting better farm livelihoods. The two-year average significant increases in grain yield of puddled transplanted rice by IRRI LLC (24.8% and 9.1%), PAU LCC (26.8% and 10.8%) and RCM (20.0% and 4.9%) over FFP and SFR, respectively. The two-year mean agronomic efficiency was found to be significantly better with IRRI LCC (57.5% and 39.6%), PAU LCC (52.1% and 34.8%) and RCM (57.6% and 39.7%) compared to FFP and SFR, respectively. Similarly, Kg N uptake Kg N applied −1 was significantly better with both the LCC and RCM-guided nitrogen application than FFP and SFR. Moreover, it was discovered that N management using SSNM choices reduced total GHG generation. According to our research, the farmers were applying nearly identical amounts of nitrogen, and SSNM tools allow for the efficient management of nitrogen in semi-arid regions by adjusting the timing of application and splitting.
