METHOD OF CULTIVATING SAFFLOWER IN CONDITIONS OF SHARP CONTINENTAL CLIMATE Russian patent published in 2009 - IPC A01B79/02 

FIELD: agriculture.

SUBSTANCE: method involves primary and secondary tillage, early winter sowing, pre-emergence treatment of seeds, disease and pest control. Fertiliser elements nitrogen, phosphorous and potassium are applied fractionally: 20-30% of calculated amount of fertiliser. Phosphorous and potassium are added at primary tillage at depth 0.18-0.27 m on planned yield of achene of 0.75; 1.25; 1.75 t/ha. Nitrogen is applied on the surface during pre-emergence treatment of seeds. The remaining amount of macroelements N, P, K is applied in parts in form of topdressing in the "complete germinating seedling-branching" period - nitrogen - 0.10-0.15 of the remaining mass, phosphorous - 0.27-0.43 parts of the remaining mass, potassium - 0.06-0.08 parts, in the "branching-head formation" period - nitrogen 0.30-0.45 parts, phosphorous - 0.12-0.18 parts, potassium - 0.13-0.26 parts, in the "head formation-flowering" period - nitrogen - 0.25-0.30 parts, phosphorous - 0.30-0.35 parts, potassium - 0.52-0.55 parts, in the "flowering-achene ripening" period - nitrogen 0.10-0.35 of the remaining part, phosphorous - 0.15-0.20 of the remaining mass, potassium - 0.11-0.29 of the remaining mass.

EFFECT: guaranteed obtaining of the planned yield of safflower and increase in their oil content due to uniform ripening and efficient use by each plant of fertiliser macroelements by vegetative parts and root mass.
