METHOD FOR CULTIVATION OF SPIKED CEREAL GRAIN CROPS ON SALINE RICE CHECKS Russian patent published in 2007 - IPC A01B79/02 

FIELD: agriculture, in particular, cultivation of rice and other irrigated agriculture crops.

SUBSTANCE: method involves preliminarily growing rice and irrigating by mole drainage pattern; applying mineral fertilizers in the following doses: N - 40-50 kg/hectare, P - 60-80 kg/hectare, K - 45-60 kg/hectare of active substance; sowing treated rice seeds; flooding rice checks; discharging water from checks at the rate of 1.5-2.0 cm per day to achieve complete drainage of checks after "beginning-of-wax-ripeness" stage of vegetative phase; mowing rice into windrows and simultaneously providing double-triple threshing of windrows, with rice straw being left on check surface; before the beginning of stable-state frosts, plowing soil in checks with turning of top layer and embedding of stubble remains to 0.30-0.35 m depth; during early spring period, providing surface application of fertilizers; cultivating soil top layer by means of disk devices; sowing cereals at designed time to 0.06-0.08 m depth; providing post-sowing covering and moistening of sub-seeding soil layer by feeding water into mole drainage system; harvesting spiked cereal crops by direct combining while leaving non-grain part in the form of cuts on check surface; eliminating perennial and late-ripening weeds by means of disk devices.

EFFECT: increased yield of spiked cereal crops cultivated on saline rice checks and increased efficiency in controlling of weed plants hazardous for cultured crops.
