An increasing interest has been observed of beetroot leaf as a salad component due to recent studies focusing on their nutritional value. The randomized field experiment was carried out on lowland chernozem soil with 6 varieties, 3 replications and 2 sowing dates. Sampling was performed on 23 of August 2018 at the stage of 30 and 50 days of vegetation, where leaf (30 and 50 days) and root (50 days) were collected. Total dry matter, folic acid and nitrate content were evaluated. The results of this investigation show that higher total dry matter content was measured in the root (8.47–10.30%) compared to the leaf in both developmental stages (6.47–9.20%). Nevertheless, higher folic acid content was found in the young leaves of 30 and 50 days of development (58.77–113.86 µg 100g-1). Among the examined varieties, Bonel has presented great amount of folic acid not only in the leaves (99.35–113.61 µg 100g-1), but also in the root (89.99 µg 100g-1). Finally, lower nitrate content was found in Libero (316.16 mg kg-1) at 30 days and in Akela (340.41 mg kg-1) at 50 days of development. Thereby, fresh consumption of beetroot leaves are highly recommended.

The purpose of the work is to study the effectiveness of using horny hoofed crumbs from the waste of the meat processing industry as an organic fertilizer, in comparison with mineral nitrogen fertilizers and zeolite-containing trepel in the Chuvash Republic. The direct effect was determined on potatoes and fodder beets, the aftereffect was determined on spring barley. The soil of the experimental plot is light gray forest with a low (2.5 ... 2.6 %) humus content. The application of horn-hoof crumbs to potatoes and fodder beets at a rate of 430 kg/ha, equivalent to N60, together with phosphorus-potassium mineral fertilizers (P60K60), in terms of influence on crop yields, was not inferior to the effect of a complete mineral fertilizer at a rate of N60P60K60. In the variants with the introduction of horn-hoofed crumbs and phosphorus-potassium fertilizers, both independently and with the addition of zeolite-containing trepel at a rate of 2 t/ha, compared with the use of complete mineral fertilization, on average for 2012–2016. an increase in the biological activity of the soil was noted by 7.1 ... 11.0 %; in potato plantings, the leaf surface area increased by 7.0 ... 15.1 thousand m2/ha, the dry matter content in tubers - by 1.4 ... 2.5 %, their marketability - by 0.4 ... 0.7 %, the nitrate content decreased by 1.14 ... 1.45 %. In the crops of fodder beets, the leaf surface area of plants increased by 3.3 ... 5.0 thousand m2/ha, the dry matter content - by 0.8 ... 2.8 %, the concentration of nitrates - decreased by 43.9 ... 40.3 %. The coefficient of energy efficiency of the combined use of horn-hoofed crumb and trepel for row crops was at the level of 1.0. The aftereffect from their introduction was noted the next year when growing barley, the coefficient of bioenergy efficiency was 2.0 ... 2.2

Growing Period

A pot and a field experiment were conducted to evaluate the effects of different nitrogen and chloride fertilizer levels on the nitrate content of beetroot. The yield and dry matter content were also determined. Sulphate fertilization was used as a control to chloride fertilization. There was a considerable decrease in the nitrate content of beetroots during the growing season. High nitrogen fertilization caused nitrate accumulation in both experiments. Chloride had a significant decreasing effect on the nitrate accumulation towards the middle of the growing period in the pot experiment. In the field experiment, chloride also decreased nitrate accumulation towards the middle of the growing period, soon after additional application of ammonium nitrate limestone (13.8 % NH4-N; 13.7 % NO3-N). Chloride tends to decrease nitrate accumulation only at an early stage of root development when nitrate is not the only source of nitrogen in the soil. The yield was higher on high nitrogen supply, in the pot experiment also on chloride application. Nitrogen decreased the dry matter content, but chloride had this effect only in the field experiment.

<p>The aim of a two-year study was to characterise selected <em>Allium cepa </em>L. genotypes with regard to their ability to accumulate nitrates in bulbs as well as to search for a possible relation between NO<sub>3</sub><sup>-</sup> concentration and dry matter content. Fifteen cultivars of edible onion, mostly of long-day genotype with different growing periods, bulb size and skin colour, were taken for the experiment. Seeds of particular cultivars were obtained from the following seed companies: Spójnia Nochowo (‘Labrador’, ‘Takstar F<sub>1</sub>’,‘Tęcza’, ‘Warna’, ‘Zorza’), Polan (‘Polanowska’, ‘Topolska’), PlantiCo Gołębiew (‘Alibaba’, ‘Efekt’, ‘Kristine’, ‘Niagara F<sub>1</sub>’),and PlantiCo Zielonki (‘Bila’, ‘Irka’, ‘Wenta’, ‘Zeta’). Plants produced from seedlings were grown in the experimental field of the University of Agriculture in Kraków. After crop harvesting and additional drying, nitrate and dry matter content in bulbs of all cultivars were measured.</p><p>The following cultivars: ‘Efekt’, ‘Labrador’ and red-skinned ‘Wenta’, were characterized by the lowest ability to accumulate NO<sub>3</sub><sup>-</sup> in bulbs. The highest nitrate content was noted in bulbs of ‘Takstar F<sub>1</sub>’ (a very early-season cultivar), followed by ‘Bila’ and ‘Tęcza’. A weak, yet statistically significant negative correlation between nitrate and dry matter content was observed. The highest dry matter content was determined in bulbs of white-skinned ‘Alibaba’, while the lowest – in brown-skinned ‘Labrador’.</p>

Yield And Quality

The effects of nitrogen fertilization on the yield and quality of early potato (Solanum tuberosum L.) were studied at MTT Agrifood Research Finland during 1996–1997. Cultivars were harvested at three times. The experimental layout was a split-split-plot with harvest times as main plots and nitrogen fertilization and potato cultivars as the subplots. The fertilizer treatments were 60 and 120 kg N ha-1 and the cultivars tested were Timo, Gloria and Van Gogh. The harvest times were 57–62, 70–75 and 85–90 days after planting. Application of 120 kg N ha-1 intensifi ed canopy development and increased leaf area of the stands. At early harvest the tuber yield of all cultivars receiving the higher nitrogen application increased by 0.5–2.5 t ha-1. The highest yielding cultivar was Timo. At last harvest, the higher nitrogen treatment increased yield by 3.0–6.2 t ha-1. The highest yielding cultivars were Timo and Van Gogh. The dry matter content of tubers was very low, 13.8–17.2%, at the fi rst harvest and the higher nitrogen application reduced dry matter content by 0.3–1.0%. The highest fertilizer application rate resulted in the largest tuber size. Nitrogen application, however, affected the quality of potatoes by decreasing the dry matter content. The nitrate content in tubers increased signifi cantly with the increasing level of nitrogen. The range of nitrate content in tubers fl uctuated between 13 and 189 mg kg-1 fresh weight showing good controlling of nitrate values. Harvest time affected sucrose content and the reducing sugar content in tubers, but nitrogen fertilizer did not change the sugar content of tubers. As tuber yield and quality during a short growing season are affected mainly by intercepted radiation, methods to increase tuber yield should focus on reducing the time to emergence, improving haulm growth after emergence and increasing the harvest index.;

Fertilizer System

In the conditions of the Komi Republic, the effectiveness of various doses of organic and mineral fertilizers, as well as their combined use in short-term feed crop rotation, was studied in a field stationary experiment on sod-podzolic soil. As a result of scientific research (more than 40 years), it was found that the organo-mineral fertilizer system was the most effective. As a result of long-term research, it was found that the most significant yields of forage crops (on average for 3 rotations) were obtained using 80 t/ha of TNK and NPK: annual grasses – 4.4, perennial grasses – 6.2 and potatoes – 7.1 t/ha of high-quality dry matter. The dry matter content in potato tubers in the variants with NPK was 18.0–18.8%, on an organic background – 18.4–18.9, and with the complex application of fertilizers – 17.1–17.7, in the control – 19.6%. The amount of starch in potatoes slightly differed in the variants of the experiment and was equal to 12.6–13.1%. The nitrate content did not exceed the MPC (250 mg/kg of raw mass). The amount of dry matter of annual and perennial grasses changed slightly and amounted to 19.0–19.8 and 25.0–26.8%, respectively. It was found that fertilizers contributed to the increase in crude protein in annual and perennial grasses to 13.1–15.0 (in the control – 11.2%) and 8.8–10.6% (in the control – 8.1%).

Research staff All-Russian Scientific Research Institute of Vegetable Growing – Branch of the Federal State Budgetary Scientific Institution Federal Scientific Vegetable Center in collaboration with Russian state agrarian University – Moscow Timiryazev agricultural Academy conducted research (2014-2016) on the effect of fertilizers and plant growth regulators on changes in the quality of onions of the Pervenets F1, Bennito F1 hybrids and Poisk 012 F1 during storage. As a result of research, the greatest effect was obtained from the complex application of N90P90K90 in combination with trace elements (tenso-cocktail) and a growth regulator Zircon. This system allowed to obtain high biochemical parameters of onions. At the end of the 7 months of storage (October-may), the highest dry matter and sugar content and the minimum nitrate content was observed in Pervenets F1 onions, as well as in hybrid Bennito F1. In the latematuring hybrid onions Poisk 012 F1 at the end of storage, the dry matter content decreased to 6,8-7,3%, sugars to 3,6-4,1%, vitamin "C" to 3,2-4,9 mg%, and nitrates increased to 92,1 mg/kg, which led to a decrease in product quality and large losses of onions from diseases and natural losses (up to 48-59%). The main reason for these losses was the lack of maturity of bulbs,low solids and sugars during harvest. It is obvious that for long-term storage it is necessary to use bulbs with a dry matter content of at least 10%. It was found out that feeding of onions during the beginning of the formation of food organizations with potassium nitrate, treatment with a growth regulator of Zircon and a complex of microelements of tenso-cocktail contributes to better preservation of the quality of onions.

Spinach Leaves

Abstract The aim of the present study was to investigate the influence of spraying with Aminoplant on the yield of two spinach cultivars in the spring and autumn cultivations. The experiment was carried out in 2008 and 2009 in the experimental station of the University of Agriculture in Krakow, Poland. Three factors were taken into consideration: (1) cultivar: ‘Rembrandt F1’ and ‘Spiros F1’; (2) time of cultivation: spring and autumn; (3) dose of Aminoplant: control (without Aminoplant), 1.5 dm3 ha-1 and 3.0 dm3 ha-1. The spinach yield was dependent on the time of production and cultivar type, and ranged between 18.6-44.8 t ha-1. Both cultivars yielded better in autumn cultivation. Spraying with Aminoplant had no effect on spinach yield. Dry matter content in spinach leaves was between 6.3-11.2 g 100 g-1. Spinach grown in the autumn had a greater content of dry matter in comparison to the spring cultivation. In 2009, ‘Rembrant F1’ was characterized by greater dry matter content than ‘Spiros F1’. Aminoplant in a dose of 3.0 dm3 ha-1 lowered dry matter content in spinach leaves as compared to the control. The nitrate content in spinach was differentiated (558-3506 mg NO3 kg-1 f.m.) and depended on the time of cultivation, the cultivar, and the Aminoplant dose.

Vegetative Organs

The dry matter and moisture contents of the aboveground vegetative organs and kernels of four maize hybrids were studied in Martonvásár at five harvest dates, with four replications per hybrid. The dry matter yield per hectare of the kernels and other plant organs were investigated in order to obtain data on the optimum date of harvest for the purposes of biogas and silage production.It was found that the dry mass of the aboveground vegetative organs, both individually and in total, did not increase after silking. During the last third of the ripening period, however, a significant reduction in the dry matter content was sometimes observed as a function of the length of the vegetation period. The data suggest that, with the exception of extreme weather conditions or an extremely long vegetation period, the maximum dry matter yield could be expected to range from 22–42%, depending on the vegetation period of the variety. The harvest date should be chosen to give a kernel moisture content of above 35% for biogas production and below 35% for silage production. In this phenophase most varieties mature when the stalks are still green, so it is unlikely that transport costs can be reduced by waiting for the vegetative mass to dry.
