Object of researches : lettuce a stem, ромэн, charts, termsof sowing, methods of cleaning up, terms,norms, types of regulators of height and plant hormones. Aim of work - to work out the elements of technology ofgrowing of in current use зеленных not cultures (lettuce ofstem and romen) on seminal aims. Methods of researches : the field, statistical, calculation. Influence of charts of розмещения plants of lettuce ofvarieties of stem and ромэна is set on seminal aims.Optimal is a chart of a 70х15 cm, at density ofstanding 95,2 thousand шт./of ha. The increase of seed forlettuce of ofstem makes 19 of varieties romen - to the 23. Productivity on 13,4 and 26 at thedecline of density of standing of plants to 41 000/ha at achart 70х35 sm. The optimal term of sowing of seed of lettuce of stem andромэна is on April, 25. Productivity of seed of lettuce stemmade 0,28 т/ha, and lettuce of romen of 0,44 т/ha. At theearly terms of sowing(on April, 15) the productivity of lettucewent down on 24,3-27,5. The optimal term of cleaning up of lettuce isa period of opening of 75% on plants during realizationof cleaning up of direct . Productivity of seed of lettuce stem rose to 0,36 т/ha, romen of 0,43 т/ha (an increase to control was 7,5-20 Treatment of plants of lettuce stem in the period of 3-5 leaves and at the beginning of stooling in concentrationsprovided 25,50 mgs/of ha increase of the productivity of seedon 14-17. Lettuce of romen most increase of seed 27 itis got at control variants, the plants of that treatpreparations of ДГК- 6, ДСК- 7 and preparation of ДСК- 10 ina concentration 9 that 18 mgs/of ha.
