METHOD FOR CULTIVATION OF LEGUMINOUS-BLUEGRASS MIXTURES Russian patent published in 2005 - IPC

FIELD: feed production in irrigated agriculture.

SUBSTANCE: method involves providing, before ameliorative soil cultivation, technological irrigation, stubble shelling, mellowing, moldboard plowing by means of skim colters, early spring harrowing, presowing cultivation to predetermined depth, covering before and after sowing. Leguminous and bluegrass mixtures are sown by coverless sowing method in parallel alternating rows with 0.12-0.15 m spacings. Optimal ratio of leguminous grass and bluegrass crops is 60% and 55%, respectively, relative to predetermined sowing norms of single-type crops and depending on sowing depth. Mineral feeding mode is kept by applying into plow layer of phosphate-potassium fertilizers at design doses providing three-year usage of herbage, and nitrogenous fertilizer at fractional differentiated doses depending on mowing state. Irrigation mode is supported by irrigation at the end of September and at the beginning of October at irrigation norm of 600-700 m³/hectare. Plant care on sown grass mixtures is provided by harrowing after each mowing procedure and by slitting to 0.4-05 m depth in autumn each year. Green mass is harvested during heading phase of bluegrass and during budding-flowering phase of leguminous grasses.

EFFECT: stabilized yield of high-quality feed produced from leguminous-bluegrass mixtures and reduced cost of product.
