METHOD OF SAFFLOWER CULTIVATION Russian patent published in 2009 - IPC A01B79/02 

FIELD: agriculture.

SUBSTANCE: invention refers to agriculture. The method consists in deep main cultivation of soil, in pre-sowing surface treatment of soil, in sowing, in early spring pre-emergence harrowing, in after-emergence inter-row cultivation and in harvesting grain part of plant for seeds. In late autumn period there are formed two-slope topless ridges at the distance of 0.70±0.02 m one from another. In early spring period there is performed correction of ridges; when temperature in ridges surpasses +5°C, achenes are sowed into compacted tops of ridges at the depth of 0.04-0.06 m. When 2-4 true leaves emerge, flexible watering pipelines of a drip irrigation system are mechanically laid along rows of plants onto compacted tops of ridges. At drip irrigation the following fertilising elements: nitrogen, phosphorus and potassium - are introduced together with water during the period of vegetation separately at the following calculated amount of fertilisers for planned yield of safflower achenes: 1.75; 2.00; 2.25 t/hectar during the phase of "branching": nitrogen 30-40%, phosphorus 20-25% and potassium 5-10%; during the phase of "head forming": nitrogen 25-45%, phosphorus 15-20%, and potassium 15-25%; during the phase of "flowering": nitrogen 20-25%, phosphorus 25-35%, and potassium 30-40%; and during the phase of achenes ripening: nitrogen 5-10%, phosphorus 20-40%, and potassium 25-50%. Calculated dozes of mineral fertilisers are introduced in form of solutions of orthophoshoric acid H₃PO₄, carbamide (NH₂)₂CO and potassium chloride KCl.

EFFECT: method facilitates raised yield of safflower achenes and their oil content.
