The effect of fertilizers application by the method of fertigation with drip irrigation during seabuckthorn growing in the nursery was estimated. The research has been carried out in the nursery field, in the forest-steppe zone of Altai Krai in 2019-2020. The soil on the experimental plot is gray-forest, reaction of the medium pH 5.8-5.9. The content of nitrate nitrogen was in the range of 7.8-9.8 mg/kg in the control variant; after fertilization, these values rose to 87.9 mg/kg. Nitrate nitrogen was determined by the ion-selective method. The soil at a high level is provided with mobile phosphorus 342-453 mg/kg and potassium 181-355 mg/kg - determined according to Chirikov. The research object – is one-year-old seabuckthorn trees of Altaiskaya cultivar. Urea was applied as nitrogen fertilizer in three rates of the active ingredient (40, 60, and 80 kg/ha). Double superphosphate (30 kg/ha) and potassium chloride (30 kg/ha) were used as the background. The soil moisture level was maintained at 70-80% of the LWC. The effectiveness of fertilizers was assessed by the marketable yield of two-year-old seedlings and their quality indicators. The measurements were carried out in the fall, after excavation. According to the values of the parameters of the aboveground part, the dose of nitrogen fertilizer of 60 kg/ha turned out to be the best option. At the same time, the seedlings had a height of 89.5 cm, the number of branches was 4.4 pcs., The diameter of the trunk was 8.4 cm, which is 15.4 cm, 0.5 pcs. and 1.3 mm above the control. The yield of seedlings of the first commercial grade in the experiment averaged 164 pieces. (82.8%), the maximum is marked on the N60P30K30 variant 190 pcs. (93.8%). Control without the use of fertilizers in all respects is significantly inferior to options with fertilizers. Thus, the use of nitrogen fertilizers has a positive effect on the quality of the seabuckthorn planting material. As a result, the utilization of nitrogen fertilizers has a positive effect on the quality of the seabuckthorn plant material, while higher concentrations become unprofitable compared to low ones due to high costs and insignificant differences in the quality of trees

Abstract The aim of the research is to study the effect of different backgrounds of mineral nutrition on the yield and quality of oilseeds of winter false flax in different regions of cultivation. The research was conducted in two contrasting regions: the forest-steppe of the Middle Volga region (Penza Research Institute of Agriculture) and the Central steppe zone of Crimea (Crimean Research Institute of Agriculture) in 2018-2020. The object of the research was the winter false flax varietal Baron. In the experiment, the effect of nitrogen fertilizer fertilization on the productivity of winter false flax at a dose of 0 to 60 kg of active substance per hectare with a step of 15 kg has been studied. Ammonium nitrate was used as nitrogen fertilizer. In the experiments of Penza Research Institute of Agriculture, the yield increase with nitrogen fertilizer was 0.07-0.19 t/ha. The highest yield of winter false flax was obtained in the variant with the introduction of nitrogen at a dose of N30, which was 1.61 t/ha, which significantly (0.19 t/ha) exceeded the variant without fertilizers. In the conditions of the Crimea, the yield of winter false flax in the average three years was not high and ranged from 0.95-1.16 t/ha. Fertilizing false flax with nitrogen at a dose of N30 led to an increase in yield by 0.21 t/ha, the productivity of the crop was 1.16 t/ha. Nitrogen fertilizer fertilization led to a slight decrease in the oil content of the seeds. In both regions, the fat content was greatest in the variant without fertilizer and was 39.9 and 40.9 %.

The productivity of agricultural crops is the most variable and integral indicator of their vital activity, which accumulates their genetic potential, soil fertility, weather conditions and components of agricultural technology. Soybean under optimal growing conditions (the reaction of the soil is close to neutral, sufficient phosphorus and potassium nutrition, the use of nitraginization) assimilates from the air about 70 % of the total nitrogen requirement. Therefore, it is believed that it is enough to apply only a starting dose of nitrogen fertilizers (20–40 kg/ha a. s.), to get a high yield with good indicators of grain quality. The results of studies of the influence of long-term (8 years) application of different doses and ratios of fertilizers in field crop rotation on podzolized chernozem in the conditions of the Right -Bank Forest-Steppe of Ukraine on the yield and quality of soybean seeds preceded by spring barley were presented. It was found that crop yields could be increased by 18–77 % owing to different doses, ratios and types of fertilizers. The highest indicators of seed yields for three years of the research (3,02 t/ha) were obtained under the application of mineral fertilizers at a dose of N110P60K80 per 1 ha of crop rotation area, including under soybean – N60P60K60. Exclusion of the nitrogen component from the complete fertilizer (N60P60K60) reduced its yield by 26 %, phosphorus – by 17, and potassium by 11 %. There was no significant decrease in soybean yield in the variant of the experiment with a decrease in the proportion of potassium in the composition of complete mineral fertilizer (N60P60K30) for three years of study. The largest mass of 1000 soybean seeds was formed at doses of N60К60 fertilizers, and their protein content — under the application of complete mineral fertilizer in doses of N60P60K60 and N60P60K30.

The aim of the work is to study the effectiveness of the use of trace elements on potato varieties of different ripeness groups in the northern forest-steppe Ob in the Novosibirsk region. Experimental data were obtained on leached black soil of Novosibirsk region in 2017–2019. The generally accepted technology of potato cultivation was used for the experiments. Since autumn, fertilizers at a dose of P90K90 were applied as a general background for potatoes. Nitrogen fertilizers (60 kg / ha) were applied in the spring for pre-sowing cultivation. Foliar dressing with microelements (Cu, B, Zn) was used at the beginning of the budding phase of potato plants: copper – 20, boron – 45, zinc – 50 g of active ingredient per 1 ha with a working fluid consumption of 300 l/ha. Trace elements increased the growth and development rates of potato varieties of three groups of ripeness. In varieties Liubava (early), Svitanok Kievsky (mid-early), Tuleevsky (mid-season), the use of trace elements contributed to an increase in the development indicators of the photosynthetic apparatus (maximum and average leaf area and plant productivity) by an average of 21%, especially against the background of boron and zinc. Foliar dressing of potatoes increased the yield parameters by an average of 24 % relative to the control (water). The increase in the marketability of tubers reached 12 %. A greater effect was achieved against the background of boron use: a significant increase in yield, dry matter, starch, vitamin C. In variants with microelements, the susceptibility of potatoes by rhizoctonysis decreased.

In China, the quantity of nitrogen fertilizer applied is large, but as a consequence of a high level of loss, its utilization rate is low. Compared to common rice, the new giant rice has interesting characteristics, namely high biological yield and good efficient use of fertilizer. However, it becomes urgent to further consider the appropriate rate of nitrogen fertilizer to be applied. The giant rice varieties Feng5 and Feng6 were set up in a pot experiment and a field experiment under five doses of nitrogen fertilizers, namely, 0 kg·ha−1 (CK), 75 kg·ha−1 (T1), 150 kg·ha−1 (T2), 225 kg·ha−1 (T3) and 300 kg·ha−1 (T4). Parameters such as leaf area index (LAI), lodging index (LI), nitrogen utilization rate, photosynthesis rate and grain yield were measured. The results showed that with the increase of nitrogen dose in a certain range, LAI, plant height, the number of tillers, net photosynthetic rate (NPn), the transpiration rate (Tr), and the grain yield increased while the lodging index (LI), the nitrogen agronomic utilization rate (AE) and nitrogen partial productivity (PFPN) decreased. Additionally, with the increase of nitrogen application, the grain yield index (HI) and nitrogen contribution rate (FCRN) of rice presented a parabolic trend.

Abstract The purpose of the research is to study the effect of the fungicide Lamador and the humic preparation Rostok on the quality of spring wheat and spring barley in the conditions of the northern forest-steppe of the Tyumen region. According to the yield, we found that pre-sowing seeds treatment with Lamador protectant and joint treatment with Rostock contributed to an increase in yield by 0.70 t/ha of spring wheat and 0.15 t/ha of spring barley, in the option with the pre-sowing seeds treatment with Lamador protectant and Rostock preparation by 0.90 t/ha and 0.10 t/ha. The highest yield of spring wheat was noted in the third option – 4.10 t/ha, of spring barley in the second option – 3.52 t/ha. An increase in the thousand kernel weight was noted in the crops under study. The highest thousand kernel weight was observed for spring wheat and spring barley in the third option – 30.2 g and 54.3 g, respectively. The maximum protein content in the spring wheat grain was noted in the third option –13.3%, which is higher than the control option by 1.3%, for spring barley we also noted protein increase by 0.4-0.5%. Thus, the experimental application of the fungicide Lamador together with the preparation Rostok for wheat seeds treatment demonstrated a positive effect of the protectants on plants in the agro-climatic conditions of the forest-steppe zone of the Tyumen region and contributed to an increase in crop yield by 28% for spring wheat and 4% for spring barley, which proved the need for their use in the plant protection system, to increase the productivity and quality of the grain obtained.

Abstract. The purpose of the research is to study the influence of the timing and depth of planting potatoes on the photosynthetic productivity, yield and quality of tubers of varieties of different ripening in the forest-steppe zone of the Chelyabinsk region. Research methods. The setting of field experience, analysis and generalization of research results are performed in accordance with classical methods. Results. The optimal time and depth of potato planting in the Chelyabinsk region was established – planting May 12–15 to a depth of 5–6 cm. This combination of agricultural methods provides the greatest photosynthetic potential (Rozara – 3.49 million m2/day, Kuzovok – 4.66 million m2/day), effective assimilation of photosynthetically active radiation (FAR assimilation coefficient: Rozara variety – 3.4 %, body weight – 3.6 %), high yield (Rozara – 35.4 t/ha, body weight – 38.3 t/ha) and the quality of potato tubers (starchiness of Rozara tubers – 16.8 %, Kuzovok – 15.84 %, starch collection per unit area 6.10 and 6.28 t/ha respectively). The late planting period (June 5–12) reduced the photosynthetic potential (Rozara varieties – by 18.7 %, Kuzovok – by 23.6 %) and the FAR coefficient (Rozara – to 2.5–2.6 %, Kuzovok – to 3.0 %). As a result, there was a decrease in the yield of the Rozara variety by 5.1–8.1 t/ha, Kuzovok – by 7.1–7.2 t/ha depending on the depth of planting and a deterioration in the quality of tubers. The dry matter content in late-planted tubers of the Rozara variety decreased by an average of 2.7 %, starch – by 2.29 %, and in the Kuzovok variety – by 2.9 and 1.83 % compared with planting in the second decade of May (accumulation nitrates in tubers increased 2.06 and 2.48 times, respectively). Planting to a depth of 5–6 cm provided an advantage in the second decade of May, and to a depth of 10–12 cm – when planting potatoes in the third decade of May and early June. Scientific novelty. In the conditions of the forest-steppe zone of the Chelyabinsk region, the dependence of the planting depth on the potato planting period is revealed. When planting at the optimum time (May 12–15), the best results are provided by a planting depth of 5–6 cm, while in the third decade of May and early June, the potato planting depth should be increased to 10–12 cm.
