The effect of correlation between a spring wheat variety with soil tillage technologies and doses of nitrogen fertilizers on the interannual yield stability

There was studied the possibility of reducing effect weather conditions on spring wheat productivity in Non-Blackearth zone due to improving tillage technologies. has been established that soddy-podzolic light loamy soil, fields Ivanovsky Research Institute Agriculture period 2013–2019, difference number productive stems per m2 when using plowing or minimal not significant HTC changed from 0.73 2.65, except year 2017 (HTC = 2.19), there increased soil moisture throughout vegetation period. The advantage under these 30 %. According kernels ear, identified a (more than 20 % 2.65; 0.99)) over minimum (by 13–14 %) during years with booting stage. When applying experimental tillage, have formed areas variable density lower part arable layer, each which is favorable for plant development certain moisture. transition 1–6 Number ear significantly exceeded this indicator 5–18 entire range Compared plowing, according 0–27 74.8 %, and 32.4 mineral fertilizers parameters yield structure 1.8 26.2 respectively.
