Productivity and quality of winter wheat grain in crop rotations with different types of fallow and at different levels of fertilization

The purpose of the current work was to study effect various winter wheat forecrops (weedfree fallow, green sown fallow) and fertilization levels (control without fertilizers, NPK–60 kg.a.i./ha, NPK–80 NPK–100 kg.a.i./ha) on productivity quality grain. carried out at Federal State Budgetary Scientific Institution “Kursk FARC” in 2018–2020. There has been established that large-sized grain grown a crop rotation with fallow. an increase mineral fertilizers’ doses, differences between rotations raised. In evenness also higher, by 0.3 0.5 % more than manure weedfree found regardless rotation, dose increased. determined trait ‘1000-grain weight’ highest when it fallow 48.4 g which due improvement nutrient regime soil introduction manure. growing variant crude gluten flour 2.3 2.5 This pattern preserved fertilized backgrounds. indicator percentage increased growth fertilizer. best terms elasticity. Winter kg.a.i./ha higher unfertilized control kg.a.i. / ha noted there is significant productivity, for example, from 4.39 6.19 t/ha fertilizer application rates.
