Isolation of adaptive varieties of tomato and innovative technologies for their cultivation on slightly saline soils of the Bukhara region

The article presents the results of assessing collection tomato hybrid varieties in terms early maturity, adaptability, formation leaf surface, tops, root system and productivity, as a result, high-yielding, adaptive improvement elements agricultural technology for their cultivation, such irrigation regimes, fertilizer rates, planting patterns standing density slightly saline soils. It was revealed that were distinguished - Seraj F1, Tomck Bobcat Lojain which formed tall plants (71.2-80.2 cm) with surface area (0.672-0.747 m 2 ), weight 124-144 g, tops 473-574 fruit yield per bush 1716-2305 g. These provided highest (75.5-101.4 t/ha). In selected varieties, optimal soil moisture regime not lower than 75-85-85% PSMC application fertilizers at rate 20 t/ha manure + N200P160K100 kg/ha. At same time, (45.7-78.6 t/ha), 1 3 water (5.7-9.8 kg), consumption centner crop 2-17.5 ) content nitrates fruits did exceed recommended norm (44.7-67.8 mg/kg). scheme 90x25 cm, 44.4 thousand ha, where it high (27.7-82.1 tons).
