The article presents the results of studies in 2011-2019. to study the effect of various fertilizer norms, weather conditions on the yield and quality of potato products, soil water regime, photosynthetic activity, payment of 1 kg a.v. fertilizers with a crop increase in the conditions of the Tver region. The experiment is based on sod-podzolic light loamy drained soil with closed drainage. Potatoes were grown in 3 variants: without fertilizers, average norms and high norms. Weather conditions during the years of research (according to G.T. Selyaninov) are divided into groups: excessively humid, moist and arid. The moisture content of the arable layer of the soil under planting of potatoes, according to the gradations of these years, the average vegetation period was 73, 60, 39% of the lowest moisture capacity. A more favorable state of the water-air regime of the soil during the cultivation of potatoes according to the ridge technology during the growing season was formed in excessively wet years, in the wet years the plants experienced a lack of moisture in certain phases, especially during the period from tuberization  to ripening. In dry years, plants experienced a large lack of moisture throughout the growing season. On average, according to the experimental variants, a higher potato crop was formed in excessively wet years compared to wet years by 21%, and with dry ones by 68%. The use of fertilizers had a positive effect on the formation of potato crops and depended on weather conditions. A greater effect from the use of fertilizers was noted in excessively wet years, with average rates the yield increased by 32.2 t / ha, at high - by 41.5, in wet - by 10.3 and 14.9, respectively, in dry - by 11.0 and 16.8. The share of weather conditions in crop variability was 23%, fertilizers - 61%.

Relevance. A priority in the selection of watermelon is the creation of new competitive varieties that combine resistance to adverse stressors, high yield and excellent fruit quality. The purpose of this study is to show the influence of weather conditions on the growing season, yield and quality of watermelon fruits and the influence of growing conditions on the growth and development of watermelon plants.Materials and methods. The study used 5 varieties of watermelon included in the State Register and 2 new varieties, ready for transfer to the State Variety Test. During the research, all observations and counts were carried out in accordance with the State Variety Testing Methodology and the Field Experience Methodology.Results. In the process of research, it was found that the length of the growing season largely depends on the amount of precipitation and the sum of active temperatures, as well as on their distribution in interphase periods. It was noted that in the year with the highest rainfall, the growing season was the longest. Productivity for the analyzed period varies from 14.2 t / ha to 20.7 t / ha in the early group, from 19.4 t / ha to 24.9 t / ha in the average. The highest yields were recorded in 2017 with the least rainfall. Growing conditions had a significant impact on the quality of watermelon fruit: the solids content ranged from 9.4% to 12.8%, total sugar - from 7.70% to 11.35%.

Data of long-term researches (2015–2018) in southern forest-steppe zone of the Republic of Bashkortostan, is justified theoretically and experimentally the mode of irrigation of potatoes on leached chernozems of unsatisfactory, satisfactory and good ameliorative condition of irrigated lands. For the growing periods of potatoes with different heat and moisture supply, the number of watering, the timing of their implementation, irrigation and irrigation norms are established. On lands with unsatisfactory meliorative state the number of irrigation depending on weather conditions of potato vegetation period varied from 0 to 3 (1.5 on average) with average irrigation norm – 990 m3/ha. With satisfactory meliorative state of lands the number of irrigation on average increased from 0 to 4 (2.3 on average) with irrigation norm – 1305 m3/ha. On lands with good meliorative state the number of irrigation was the highest – from 1 to 5 (3 on average) with average irrigation irrigation norm is 1653 m3/ha. It was noted that in the dry periods of potato vegetation the greatest number of watering was carried out (3–5 watering), and in the wet periods (2017) watering was not carried out except for the area with a good reclamation state, where only one irrigation was carried out by the norm of 550 m3/ha. Water consumption of potato was studied in dynamics as a whole during the growing season and the months of the growing season depending on weather conditions of vegetation period and land reclamation condition of irrigated lands, as well as in the control (without irrigation). The lowest total water consumption was in the area without irrigation and averaged 226.8 mm. In irrigated areas, its values increased to 319-353.4 mm. The average daily water consumption varied from 2.12 to 3.3 mm. The highest rates of potato water consumption were observed in June and July, and the lowest – in May and August. In the total water consumption of potatoes on the site without irrigation, the largest share was occupied by atmospheric precipitation and in addition to them the arrival of moisture from the soil. Irrigation water was used in irrigated areas along with precipitation, the share of which was 30.2–46.1 %.

No significant studies have yet been reported in Central Europe on the yield and quality of winter harvest pastures. The aim of the research was to collect information about the effect of pre-utilisation (June, July and August) and winter harvest date (November, December, January) on the quantity and quality of fodder from Festuca arundinacea stands. The dry matter, energy, ADF, ADL and ergosterol contents of the yield were examined and it was found that: 1. A shorter regeneration period between harvests resulted in lower dry matter levels, but also in a higher energy concentration and lower ergosterol concentration. 2. The yield and energy concentrations decreased, whereas the ADF, ADL and ergosterol concentrations increased as the winter progressed. 3. Fodder harvested in November produced the best results in terms of yield quantity and quality. The highest yield and energy values were thus achieved by harvesting in November, regardless of pre-utilisation. Despite the cold and the long period of snow cover, the energy values of samples harvested in December and January showed no significant decrease. The weather conditions were more important for fodder quantity and quality than the frequency or date of harvesting. Thus, under the continental climatic conditions in Hungary, extensive utilisation, until late November or early December, is recommended.

Potato early blight caused by Alternaria solani generates significant economic losses in crops worldwide. Forecasting the risk of infection on crops is indispensable for the management of the fungal disease, ensuring maximum economic benefit but with minimal environmental impact. This work aimed to calculate the interrupted wet periods (IWP) according to the climate conditions of A Limia (Northwest of Spain) to optimize the prediction against early blight in potatoes. The study was performed during nine crop cycles. The relative hourly humidity and Alternaria concentration in the crop environment were taken into account. Alternaria levels were monitored by aerobiological techniques using a LANZONI VPPS-2000 volumetric trap. The relationships between weather conditions and airborne Alternaria concentration were statistically analyzed using Spearman correlations. To establish the effectiveness of wetness periods, the first important Alternaria peak was taken into account in each crop cycle (with a concentration greater than 70 spores/m3). Considering the six interrupted wet periods of the system, it was possible to predict the first peak of Alternaria several days in advance (between 6 and 38 days), except in 2007 and 2018. Automated systems to predict the initiation of early blight in potato crop, such as interrupted wet periods, could be an effective basis for developing decision support systems. The incorporation of aerobiological data for the calculation of interrupted wet periods improved the results of this system.

ABSTRACT The results of two years (2010-2011) of field studies using two types of nonwoven mulches (one biodegradable, polylactic acid PLA 54 g m-2, and traditional polypropylene PP 50 g m-2) on the yield and quality of tomato are presented. Seeds of tomato (‘Mundi’ F1) were sown in a greenhouse, in containers filled with perlite and sand, and then the plants at the cotyledon stage were replanted in multipot trays filled with substrate for vegetable plants. In the last week of May, seedlings were planted on mulches in the field at a spacing of 50 × 100 cm. The mulch was maintained throughout the growing season. A plot that remained unmulched served as the control. Tomatoes were harvested once a week. The fruits were evaluated for L-ascorbic acid, dry matter, soluble sugars and nitrate content. In 2011, the analysis of the plant material showed that the concentration of L-ascorbic acid was about 23% higher in the tomato fruits harvested from plants grown on biodegradable PLA 61 g m-2 mulch in comparison to the control. A similar effect was demonstrated for the soluble sugar concentration in 2011 for both types of nonwovens.
