First, it significantly increases the number of productive panicles per unit area, with the high\u2212yield cultivar Lijiang 419 exhibiting a greater response (average yield increasing of 5.5%). Second, WNM markedly reduces mechanical harvest loss by decreasing panicle dropping. The wider row spacing of WNM (36\u00a0cm vs. 30\u00a0cm in FM) provides larger corridors for the combine header, minimizing incidental contact with adjacent plants and thereby reducing dropped panicles. Additionally, WNM improves panicle neck height uniformity by 4.7\u20135.0%, ensuring that more panicles are positioned above the cutting height and further mitigating losses.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>Consequently, the integration of optimized agronomic practices (WNM) with suitable machinery effectively boosts both yield and harvest efficiency, making WNM a promising planting pattern for mechanized rice production areas seeking high yield and low loss.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.3389\/fpls.2026.1796989","type":"journal-article","created":{"date-parts":[[2026,4,17]],"date-time":"2026-04-17T11:11:47Z","timestamp":1776424307000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":0,"title":["Wide-narrow row spacing reduces mechanical harvest losses in rice by optimizing panicle distribution: evidence from five-year field trials integrating density and cultivar variables"],"prefix":"10.3389","volume":"17","author":[{"given":"Yuedong","family":"Li","sequence":"first","affiliation":[{"name":"Liaonning Rice Research Institute, Liaoning Academy of Agricultural Sciences","place":["Shenyang, China"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Maoxing","family":"Song","sequence":"additional","affiliation":[{"name":"Tangshan Academy of Agricultural Sciences","place":["Tangshan, Hebei, China"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yue","family":"Zhang","sequence":"additional","affiliation":[{"name":"Liaonning Rice Research Institute, Liaoning Academy of Agricultural Sciences","place":["Shenyang, China"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Nan","family":"Xiao","sequence":"additional","affiliation":[{"name":"Jilin Academy of Agricultural Sciences (Jilin Agricultural Products Quality Supervision and Inspection Center)","place":["Jilin, China"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Tiexin","family":"Yang","sequence":"additional","affiliation":[{"name":"Liaonning Rice Research Institute, Liaoning Academy of Agricultural Sciences","place":["Shenyang, China"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Liang","family":"Ma","sequence":"additional","affiliation":[{"name":"Liaonning Rice Research Institute, Liaoning Academy of Agricultural Sciences","place":["Shenyang, China"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Liqiang","family":"Dong","sequence":"additional","affiliation":[{"name":"Liaonning Rice Research Institute, Liaoning Academy of Agricultural Sciences","place":["Shenyang, China"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Shuang","family":"Wang","sequence":"additional","affiliation":[{"name":"Dengta Agricultural and Rural Affairs Service Center","place":["Liaoyang, Liaoning, China"]}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1965","published-online":{"date-parts":[[2026,4,17]]},"reference":[{"key":"B1","first-page":"894","article-title":"Evaluating rice losses in various harvesting practices","volume":"4","author":"Alizadeh","year":"2013","journal-title":"Int.
