Description
Summary:The results of experimental research performed in 2011–2018 with clary sage on the lands of Private Enterprise “Dodola” of Beryslavskyi District in Kherson Region are presented. The soil of the experimental plot is dark chestnut, slightly solonetzic, medium loamy. The content of humus in the arable layer of the soil (0–25 cm) is 2.27%, total nitrogen 0.185%, phosphorus – 0.099%, metabolic potassium – 343 mg/kg. The research scheme included factors and their variants. In particular, the background of nutrition – without fertilizers, N60P30, N60P60, N60P90; depth of the tillage primary (base) – plowing to a depth of 20–22 cm and 28–30 cm; sowing times – the first decade of December, the second and third decades of March, the first decade of April; row spacing – 45 and 70 cm. Establishing of field experiment was performed by method of splitting plots. The level of yielding capacity of clary sage was stable for three years against the background of nutrition N60P90. On average, in the first year it was – 9.51, in the second year – 9.38, in the third year – 9.69 t/ha. The share of factors influencing the formation of productivity of clary sage inflorescences of the third year of use was 30.4% against the background of nutrition, for sowing – 43.9, row width – 5.3 and depth of tillage primary – 2.1% of the total yield. In the fourth year of sowing usage, the yielding capacity of inflorescences decreased sharply: to 0.82–2.16 t/ha on the background of plowing to a depth of 20–22 cm and 0.80–2.16 t/ha on the background of plowing to a depth of 28–30 cm. One of the main reasons can be declared the aging of the assimilation apparatus of plants and the disappearance of plants in the sown area. According to the obtained calculations, the highest indices of conditional net profit(500.0 thousand UAH/ha) and the level of profitability (322.5%) were registered on the variants of the experiment, where plowing was performed to a depth of 20–22 cm, mineral fertilizers N60P90 and clary sage sowing was performed in the first time with a row spacing of 45 cm. The most profitable was the second year of usage of clary sage. During this period, the conditional net profit ranged from 132.0 to 508.3 thousand UAH/ha. To maximize the natural and material potential of farms of various forms of ownership in the southern part of Ukraine it is advisable to grow clary sage, capable of drip irrigation, application of mineral fertilizers N60P90, sowing with a row spacing of 45 cm for 3 years of use to form yielding capacity of inflorescence at level 9.5–15.0 t/ha.
