The total area of ​​the plots in small-scale experiments is from 50 to 100 m2, in the production – 1,7 hectares. Repetition in small-scale experiments – 4-fold, in production – is not provided. Seed treatment was carried out by the method of semi-dry dressing immediately before sowing with a working solution consumption at the rate of 10 l / t, spraying of plants – using a mounted tractor sprayer ON-400 or a hand sprayer with a working solution flow rate of 200-300 l / ha. Spraying of plants was carried out in the morning, afternoon or evening hours at a wind speed of not more than 4 m / s and air temperature up to 22 ° C.

The precursors for spring soft wheat and barley are soybean, for soy and buckwheat – spring wheat. Technologies for cultivating crops are generally accepted for the forest-steppe zone of the Altai Ob area. Wheat sowing was carried out on May 18, barley and soybeans on May 25, buckwheat on June 2, 2016. The norm of sowing wheat and barley is 4.0, soybean is 0.6, buckwheat is 1.75 million germinated grains per 1 hectare.

The harvesting of all crops in small-scale experiments was carried out manually by a shear method, buckwheat in the production experiment – two-phase: mowing in rolls – September 13, threshing of rolls – September 21, 2016. Harvest grain resulted in 14% moisture and 100% purity.

The soil in the experiments is chernozem leached medium-heavy low-humus medium loamy, typical for the Altai Ob area, with humus content in the arable layer 3.8-4.5%, medium supply with mobile nitrogen (12-14 mg / kg N-NO3 in soil layer 0-40 Cm), very high mobile phosphorus (according to Chirikov, 205-230 mg / kg in the 0-20 cm layer), and medium or elevated-mobile potassium (75-85 mg / kg in the 0-20 cm layer).

During the May-August period, precipitation fell about normal (Table 1) – 221 mm, or 107%, but their distribution was uneven: in May – 31 mm (78%), in June – 46 mm (84%), August – 28 mm (64%) and only in July – 116 mm (171%). During the period from May 13 to May 28 and from June 1 to June 18, precipitation was absent, which adversely affected the growth and development of cultivated plants, but had a beneficial effect on the growth and development of weed vegetation. The average air temperature during the vegetative period was also close to normal – 17.3 and 17.0 ° C, but in May it was 1.2 ° C lower, in June and July – higher by 1.9 and 0.8 ° C, and in August – equal to the average multi-year.

The use of Stimulin for the treatment of vegetative buckwheat plants in increasing from 0.2 and 0.5 to 1.0, 2.0 and 3.0 l / ha doses provided, on a background without seed treatment, an increase in crop yield of the crop from 2.72 to 2 , 78, 2.80, 2.84, 2.98 and 3.14 t / ha. The increment in the yield was, respectively, 0.06, 0.08, 0.12, 0.26 and 0.42 t / ha, or 2.2, 2.9, 4.4, 9.6 and 15.4% With respect to the background without plant treatment. A significant increase in the yield of buckwheat with increasing doses of Stimulin was established at doses of 2 and 3 l / ha.

Similar results were obtained with Stimulin on vegetative plants against the background of previous treatment of buckwheat seeds with this preparation. At doses of 0.2, 0.5, 1.0, 2.0 and 3.0 l / ha, the yield increased from 2.82 to 2.87, 2.91, 2.95, 3.04 and 3 , 20 t / ha. The yield increment was, respectively, 0.05, 0.09, 0.13, 0.22 and 0.38 t / ha, or 1.8, 3.2, 4.6, 7.8 and 13.5% . As against the background of untreated seeds, a significant increase in the yield of buckwheat with increasing doses of Stimulin was established at doses of 2 and 3 l / ha.

On the average for the factor B (processing of vegetating plants), the increment in the yield of buckwheat at Stimulina doses of 0.2, 0.5 1.0, 2.0 and 3.0 was 0.05, 0.09, 0.13, 0.19 And 0.40 t / ha (1.8, 3.2, 4.7, 6.9 and 14.4%). At the same time, a reliable increase in the yield of buckwheat was achieved already with a dose of Stimulina 1 l / t.

Conclusion

The use of Stimulin for the treatment of seeds before sowing at a dose of 1 l / t provides an increase in the yield of grain of spring soft wheat 0.10 t / ha (7.6%), barley 0.22 t / ha (12.6%), Soybean – 0.19 t / ha (7.1%), buckwheat – 0,09-0,16 t / ha (3,1-5,9%).

The use of Stimulin for treatment of vegetative plants at a dose of 1-3 l / ha in pure form provides an increase in the yield of grain of spring soft wheat by 0.14 t / ha (10.7%), barley by 0.20 t / ha (11 , 5%), soybean – by 0.24-0.34 t / ha (15.0-21.2%), buckwheat – by 0.12-0.42 t / ha (4.4-15.4 %).

The combination of seed treatments and vegetative plants with Stimulin at the indicated doses ensures a further increase in the yield increment of wheat grain to 0.21 t / ha (16.0%), barley – up to 0.32 t / ha (18.4%), On soybeans – up to 0.43-0.56 t / ha (26.9-35.0%), on buckwheat – up to 0.23-0.48 t / ha (8.5-17.6%).

The use of Stimulin in agricultural production of the forest-steppe zone of the Altai Territory is advisable when growing spring soft wheat, barley, soybean and buckwheat in doses up to 1 l / t when processing seeds before sowing, and in doses from 1 to 3 l / ha when processing vegetative plants.
