FIELD: agriculture.SUBSTANCE: method comprises application of macrofertilisers, plowing with soil overturning, early spring harrowing, preplant cultivation, equiplanation, sowing seedlings in soil layer, vegetation irrigation, inter-row treatments, additional fertilising, protection of plants and fruits from agricultural pests and diseases, and harvesting. Sweet pepper is grown on flood embedded sandy loam soils. The macrofertilisers NPKare applied once before plowing. Sowing seedlings in soil layer with temperature of 15-18°C is carried out, with the planting density of 71 thousand units per hectare, the arrangement diagram of 90+30×25 cm. The macrofertilisers NPKare applied in fractional manner with the irrigation water: in the stage of the third and fourth true leaf 18-22% N, 10-14% P, 14-18% K, in the budding stage 30-38% N, 28-38% P, 30-32% K, in the flowering stage 12-20% N, 16-22% P, 36-48% K, in the fruiting stage 20-40% N, 26-46% P, 6-16% K, while maintaining in the soil layer of 0-0.8 m of 80% moisture content of field moisture capacity during the whole growing period. In total 16 irrigations are carried out with the total flow rate of 260 m/ha, while the nitrate content in biologically ripe fruit up is no greater than 16 mg/kg.EFFECT: obtaining of yield of sweet pepper with low nitrate content on flood embedded sandy loam soils using the drip irrigation system.2 tbl, 1 ex |
