METHOD OF GROWING SWEET PEPPER IN DRIP IRRIGATION SYSTEM ON FLOOD EMBEDDED SANDY LOAM SOILS Russian patent published in 2014 - IPC A01B79/02 A01G1/00 A01G25/00 

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 N₁₂₀P₈₀K₁₂₀ are 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 N₁₂₀P₈₀K₁₂₀ are 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 m³/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.
