This study assesses the efficacy of Super Seeder technology, a tractor-operated machine that allows for simultaneous residue integration and seed sowing, under various paddy straw height circumstances in Nepal's Terai region. Crop residue management is critical for sustained intensification of rice-wheat systems. Despite its negative environmental consequences, residue burning before wheat sowing continues to be common in Nepal. We conducted a field experiment at the on-station of the Directorate of Agricultural Research, Koshi Province. The study applied four straw height treatments 0-5 cm, 10-15 cm, 25-30 cm, and 35-40 cm with five replications per treatment. The results demonstrated that, in comparison to both greater residue levels and residue-free plots, moderate straw heights (10–15 cm) produced better wheat emergence and a significantly better grain yield (4.03 t/ha). While early emergence rates were not significantly impacted by straw height (p>0.05), there were significant differences in biological and grain yields between treatments. According to economic analysis, under subsidized conditions(if farmer gets 75% subsidy on initial purchase of super seeder), the Super Seeder achieved a payback period of 0.64 years and cut input costs by 25%. Due to its cost-effectiveness and operational efficiency, farmers at the NARC Technology Village in Sunsari district expressed a high preference for the Super Seeder in a large plot demonstration that contrasted it with zero tillage and traditional methods. This study focuses on the potential of Super Seeder technology to improve residue management, minimize labor and fuel consumption, and promote climate-smart wheat production in Nepal.
