Cultivation of winter rape for innovative technologies (No-Till)
Winter rape is one of the most popular and promising economically cultures. In recent years, the economy getting high yields of good quality oilseeds.
Requirements for the soil. Winter rape sown on the cultivated sod-podzolic light- and medium loamy soils, characterized by a neutral reaction of the soil solution (pH 6.0-6.5). At slightly acidic soils dolomitic lime flour was performed at a dose of 4-5 t / ha.
Predecessor. Winter rape sown after the couple. The farm observed time interval accommodation for rape rapeseed 4-5 years. Fertilizers under winter rape was used according to the agrochemical analysis of the soil and the planned harvest. Before sowing randomly under cultivation have made complex fertilizers ARVI NPK "Universal" brand 8-20-30 at 200 kg nat. weight / ha. Early spring The first feeding is carried out with ammonium nitrate at a dose of 200 kg FW / ha (or N to 70 kg ai / ha). According to a second plant diagnosis of stem in feeding phase was added ammonium sulfate at a dose of 250 FV kg / ha (or N 52 kg ai / ha). Additionally applied microfertilizer Nutrivant oilseed at a dose of 5 kg / ha, which was added in conjunction with herbicides and fungicides.
Preparation and treatment of soil for planting. In the first decade of July in all fields of applied herbicides continuous action Glyphosate 2 l / ha + Agritoks 1 l / ha. Further soil treated subsoiler to a depth of 40-45 cm, and then carried out one after the other 2 cultivation Kockerling Vario cultivator to a depth of 20 cm. Before the second cultivation cultivator attached to a precision seeder APV PS300M1.
Sowing. Winter rape sat at the optimum time from 5 to 25 August closed drills, with the obligatory leaving tramline. Sowing seeds is carried out, already encrusted insecticides and fungicides (Kruyzer Rape). Seeding rate of 2.2 kg / ha or 0.5 million units per 1 ha. Seeding depth of 1.5-2.0 cm. When sown at the optimum time in winter oilseed rape plants by the end of autumn vegetation formed 6-7 developed leaves, root collar thickness reaches 7-8 mm, which contributes to the good overwintering plants.
