The study of growth regulators efficiency in the cultivation of early-maturing potato of Red Scarlett variety was conducted on gray forest soil of Kama of the Republic of Tatarstan. The reaction of the new early maturing potato of Red Scarlett variety was examined, when assessing ways to use drugs Silk and Albit (soaking seed tubers, foliage cultivation, combined processing (tuber + foliage twice). It was found, that the use of growth regulators of Silk for the treatment of tubers before planting, depending on the nutrition background, increased the productivity tubers to 2.33 – 3.32 tons per hectare, Albit drug application increased the harvest to 1.55-1.70 tons per hectare. Foliar treatment by Silk twice during the growing season has increased the yield by 3.31-4.05 tons per hectare, by Albit by 2.30-3.16 tons per hectare. When complete machining (tubers + tops) respectively by 5.18-7.16 and 4.16-5.20 tons per hectare. The most efficient option was at the processing of tubers + twice vegetative plant with growth regulator Silk in the background of calculated dozes applicant, rated on the tuber yield of 30 tons per hectare, when yield increase was 7.16 tons per hectare.

The reaction of the early ripening potato of Vineta variety to different methods of using growth regulators against the calculated background of mineral nutrition on the gray forest-steppe soil of middle Volga was studied. The effectiveness of processing planting tubers and foliar treatment of plants during their vegetation has been established. The experiments were carried out on the control without the introduction of NPK and on a fertilized background, designed to obtain a tuber crop of 40 tons per hectare. The studies were conducted on gray forest medium loam granulometric composition soil of “Zemlyaki” farm in Nizhnekamsk district of the Republic of Tatarstan. Field experiments were carried out in 2019 by employees of Plant Growing and Horticulture Department of Kazan State Agrarian University. The humus content in the arable layer of soil according to Tyurin is 3.35%, pH is 5.7, easily hydrolyzable nitrogen is 112 mg/kg of soil, mobile phosphorus is 156 mg/kg, exchange potassium is 136 mg/kg of soil, molybdenum is 0.07, copper is 0.52, boron - 0.7, zinc - 4.82 mg/kg. The effectiveness of the integrated use of growth regulators (treatment of planting tubers and foliar application of the drug during the growing season) has been established. The yield increase to control against the background without applying basic fertilizers amounted to 4.82 tons per hectare, and against the background of their application - 4.80 tons per hectare.

ABSTRACT The results of two-year observations of the growth and development of four sunflower varieties: Master, Flagman, Lakomka, Rodnik against the background of the use of three plant growth regulators: Zircon, Epin and Regoplant on the soil in the forest-steppe zone of the Republic of Ingushetia are presented. Studies have shown that the effect of growth regulators begins to manifest itself even during the period of seed germination. The length of seedlings and roots was most influenced by Zircon, less by Regoplant and Epin. Sunflower seeds treated with these growth regulators had roots 2.0-2.5 cm longer than the roots of untreated seeds (control), and the length of seedlings exceeded the control by 2.7-3.5 cm, while the Flagman variety had a small length of seedlings and roots. advantage. During the study period, the Flagman cultivar was distinguished by the highest yield, the Lakomka cultivar was somewhat less productive, and the Rodnik and Master cultivars were the least productive. On average, over two years of research, the varieties Flagman and Lakomka against the background of the use of Regoplant provided 2.5 t / ha of oilseeds, which is significantly more than other options.

An important source for increasing the sunflower yield and getting high economic efficiency consists of improving agricultural techniques for cultivation, in particular, soil and climatic conditions. Using growth regulators is one such technique. This research studies the effectiveness of the complex use of growth regulators when the treatment of seeds before planting is combined with the sprinkling of actual plants. During the whole period of the 4-year study, the maximum yield of seeds (3.233 tons/hectare), the highest oil content (52.95 %), and the gross oil production level (1713.8 kg/hectare) were obtained under the use of Zirkon growth regulator.

In South Africa the modern outlook towards time may be said to have started in 1948. Both the two major observatories, The Royal Observatory in Cape Town and the Union Observatory (now known as the Republic Observatory) in Johannesburg had, of course, been involved in the astronomical determination of time almost from their inception, and the Johannesburg Observatory has been responsible for the official time of South Africa since 1908. However the pendulum clocks then in use could not be relied on to provide an accuracy better than about 1/10 second, which was of the same order as that of the astronomical observations. It is doubtful if much use was made of even this limited accuracy outside the two observatories, and although there may – occasionally have been a demand for more accurate time, it was certainly not voiced.
