- Abstract
Studies have been performed on the sod-podzolic medium loamy soil of the Middle Cis-Urals for determining the mineral nutrition factors to ensure obtaining the yield of the Accord rape seeds of at least 1. 50 t/ha. In 2018 - 2019, the introduction of calculated doses of nitrogen (N60-80) fractionally (½ before sowing and ½ as top dressing) in the phase of three to four leaves, followed by subsequent foliar fertilization with the ZnSO4 micronutrient fertilizer (162 g/ha) in the budding phase, helped to obtain the planned yield by increasing the rape plant stand density by 8 plants/m² and the rape plant productivity by 0. 45 g. Improvement of mineral nutrition has increased the area of plant leaves of the crops in the budding phase to 27, 000 m²/ha. With the seed yield of 1. 53 t/ha, rape has ensured the gross fat yield of 687 kg/ha and the protein yield of 320 kg/ha; it has also showed the efficiency of cultivation -- the energy efficiency coefficient of 1. 64 with the cost of 10, 413 rubles per ton of seeds.
