Tillage and nitrogen managements increased wheat yield through promoting vigor growth and production of tillers

Adopting suitable tillage and fertilization technologies for wheat (Triticum aestivum L.) can address poor soil conditions high residual nitrogen following rice (Oryza sativa harvest to improve the sustainability of rice–wheat rotation systems. A field experiment was conducted in 2016–2018 investigate influence methods rates on seedling growth (at beginning over-wintering stage), tillering characteristics, grain yield. The included no-tillage (NT), rotary twice (RR), plow followed by (PR). were 270 (N270), 240 (N240), 210 kg ha?1 (N210). In 2016–2017 (higher moisture during tillage), NT improved early (i.e., leaf area biomass per stem), single spike yield, yield compared with PR RR. 2017–2018 (lower RR resulted stronger seedlings (greater tiller number more fertile tillers, higher than NT. both years, under between that With reduced application, growth, number, showed a declining tendency. We found tillers at stage (the five-leaf years) could boost this time greater stem correlated This study demonstrates fertilizer applications facilitate formation through vigor early-produced tillers.
