In the short-term field trials in the Perm Krai in 2015-2017 were aimed to research the influence of mineral fertilizers and straw on the yield capacity and some parameters of spring wheat. The trial design included: Factor A – fallow type: A1 – green-manure fallow; A2 – naked fallow; Factor B - method of fertilizer dose calculation; B1 – without fertilizers; B2 – currently applied dose of fertilizers in agriculture of Perm Krai (N30P30K30 kg/ha); B3 – average recommended doses (N60P60K60 kg/ha); B4 – dose for planning yield capacity (3 t/ha – N105P36K105 t/ha); B5 – dose for additional yield (2 t/ha N70P24K70); Factor C – straw application; C1 – with straw; C2 – without straw. It was established that seeding the spring wheat with naked fallow significantly increased the performance of this crop, on average, the additional yield over the three years was 0.12 t/ha when NCP = 0.12 t/ha. On average over the three years, application of fertilizers ensured the yield capacity of spring wheat grain equal to 2.50-2.76 t/ha. The maximum additional yield was achieved when fertilizers were applied in average recommended doses (НСР05 = 0.11 t/ha). High doses of fertilizers (N105 kg/ha) led to lodging and harvesting loss in the variants for planning yield. Application of straw of winter crops as an organic fertilizer had a significant impacted on the yield capacity of spring wheat. On average over the three years, the additional yield gained by this method was equal to
0.16 t/ha (НСР05 = 0.08 t/ha).
