Reserves of soil productive humidity are the key to high yield of sunflower MATSKOVA, Svetlana; GUMANYUK, Alexei Currently, there is a warming climate. An increase in air temperature leads to an increase in the physical evaporation of water from the soil and the transpiration of plants. As a result, the study of the question of whether the reserves of natural soil moisture supply will be able to reveal the potential of sunflower in conditions of extreme farming is very relevant. In addition to the natural moisture supply of the soil, the yield of sunflower is also influenced by such factors as precipitation, hybrids (varieties), mineral nutrition, irrigation, etc. The paper analyses the data of average annual air temperatures and spring moisture reserves for the period 2006 – 2024 and found that on average for the analysed 15 years, the climatic conditions of our region can provide a sunflower yield of no more than 2 t/ha. Spring soil moisture reserves showed a weak correlation with sunflower yield (r = 0.145), which means that this factor has only a minor influence on yield formation. The correlation strengthens (r = 0.298) if not only spring moisture reserves but also precipitation for April-May are taken into account. However, even in this case, the influence of moisture availability remains average. The average level of correlation (r = 0.505) is reached when April-July precipitation is added to spring moisture reserves. This confirms that moisture supplied during critical phases of sunflower development (June-July) plays a more important role in yield formation than spring moisture reserves alone. Knowing the spring reserves of productive moisture in the soil and the amount of precipitation for the months of April to July, it is possible to predict the yield of sunflower.

Влияние метеоусловий на урожайность подсолнечника ГУМАНЮК, Алексей; МАЦКОВА, Светлана Целью нашей работы было изучение корреляции основных климатических условий Приднестровского региона с урожайностью подсолнечника. В среднем за анализируемые 15 лет климатические условия нашего региона могут обеспечить урожайность подсолнечника не выше 20 ц/га. Зная весенние запасы влаги в почве и количество осадков за апрель-июль месяцы по уравнению регрессии можно спрогнозировать урожайность подсолнечника.

Quality of grapes of Feteasca neagra wine variety depending of grow region from the Republic of Moldova NICOLAESCU, Gheorghe; MOGÎLDEA, Olga; GODOROJA, Mariana; VOINESCO, Cornelia; PROCOPENCO, Valeria; KIMAKOVSKI, Andrei; DOSCA, Ion; MAȚCU, Gheorghe In Moldova wine production is very important for the economic development, because is traditional for local people. The Moldovan Government have a one of the main purpose in their development strategy - to develop and promotion local traditions in the word, inclusive moldavian wines produced from local varieties. In the period from 2017 to 2021, we studied the influence of ecological conditions and grow technology on the quality of grapes of Feteasca Neagra wine variety (local moldavian variety) cultivated in different regions of the Republic of Moldova – South part (Alexandru Ioan Cuza, Cahul district / Bugeac, Comrat district / Leova, Leova District); South-east part (Purcari, Stefan Voda district); Central part (Speia, Anenii Noi district / Nisporeni, Nisporeni district / Mircesti, Ungheni district). Feteasca Neagra synonymous: Coada Rîndunicii, Coada Rândunicii, Mädchentraube Schwarz, Schwarze Mädchentraube, Pasareasca neagra, Fekete Leányka. Feteasca Neagra is a local Moldavian and Romanian wine grape variety of the middle ripening period. The period from the beginning of bud break to the full maturity of berries in the conditions of the south part of Moldova is 125-140 days with a sum of active temperatures of 2700°-2800°C. The leaves are medium, cuneate-round, five-lobed, medium or deeply dissected with the edges of the lobes bent down, glabrous below with sparse bristles along the veins. The petiolate notch is open, vaulted or lyre-shaped with a pointed bottom. The flower is bisexual. Clusters are medium, cylindrical or cylindrical, medium dense. The berries are medium, rounded, purple-black. The skin is strong. The pulp is juicy. Shoot maturation is good. Productivity is 7.0-9.5 t/ha. Feteasca Neagra is moderately affected by mildew, and weakly by other diseases and pests. The grapes are used to prepare a well-colored table wine. In our research results we concluded that the quality and quantity of grapes and wine depend directly by the ecological grow conditions. In the south part we obtained early grapes by higher sugar and titratable acidity content in comparison with grapes obtained in the central or north part of Moldova. The distance between south and north experimental vineyards are about 200 km, but the conditions are very different.
