Relevance. Pumpkin is a food, medicinal and fodder crop of the Cucurbitaceae family. It is valued for its high content of vitamins, minerals, organic acids. At present, thanks to the huge variety of species and modern selection, it is possible to select pumpkin varieties for cultivation in almost any region, including areas with short and not too hot summers. Udmurtia belongs to the zone of risky farming, the end of spring frosts is observed on average in the first ten days of June, and autumn frosts on the soil are possible at the end of August. Due to the short frost-free period, it is necessary to choose earlier maturing varieties, grow the crop through seedlings and use temporary shelters. The pumpkin fruit is usually large in size, is a thick layer of pulp, covered with a dense peel. When cutting such a fruit, the pumpkin is not stored in the future, it requires urgent processing. In this connection, in recent years, portioned varieties of pumpkin, the size of the fruit of which does not exceed 1.5–3.0 kg, have become increasingly in demand.Materials and Methods. The purpose of the research: a comparative assessment of varietal characteristics of growth and productivity of pumpkin species. In 2020–2021 in the conditions of the Udmurt Republic, experiments were carried out to study the characteristics of growth and productivity of pumpkin varieties. We studied varieties of pumpkin: Pearl, Crumb, Honey Tale, Marble, Rossiyanka, Smile, Candied fruit.Results and its discussion. Within two years, pumpkin varieties of large-fruited and nutmeg were studied. On average, for two years, the pumpkin Medovaya skazka distinguished itself with the highest yield. In 2021, the yield for the Medovaya Skazka variety was 64.7 t/ha. The yield increase was obtained due to an increase in fruit weight, which in 2020 amounted to 2.9 kg, in 2021 - 6.5 kg. The studied varieties of pumpkin differed in quality indicators of fruits. On average, over two years, the varieties Rossiyanka and Mramornaya showed an increase in the content of water-soluble sugars in fruits. The fruits of the pumpkin Candied fruit and Kroshka were distinguished by a high content of dry matter.

Abstract. The productivity of wild strawberries is significantly determined not only by the biological characteristics of the variety and soil and climatic conditions, but also by agrotechnical techniques and the use of organomineral fertilizers. The effectiveness of the use of mineral fertilizers on strawberries has been proven by numerous studies [5, p. 48; 6, p. 99; 14, p. 233; 15, p. 513; 16, p.101; 17, p. 513]. The purpose is a comparative assessment of the effect of various types of complex fertilizers for strawberries. The task was to study the effect of complex fertilizers on the yield of strawberry and its structure. In 2015–2018, studies were conducted on the introduction of complex fertilizers for wild strawberries, which are used during the growing season to improve their nutrition during periods of maximum consumption of nutrients. Methods. The studies were conducted according to generally accepted methods [4], [7]. The influence of “Azophoska”, “Perm-yagodnoye” and “Fasko-yagodnoye” fertilizers on the yield and elements of its structure in strawberry was studied in the conducted studies. Results. The best results for all the years of research were obtained when using the pre-planting application of the fertilizer “Fasko-yagodnoye”. In this variant, there was a significant increase in the number of berries by 1.8 pcs., their weight by 0.68 g and yield by 0.13 kg/m2. Scientific novelty. For the first time in the conditions of the Udmurt Republic, the effect of the pre-planting application of complex fertilizers “Perm-yagodnoye” and “Fasko-yagodnoye” was studied on strawberry garden. Practical significance. The obtained research results are of great practical value, since it is proved that the productivity of wild strawberries in the Udmurt Republic increases with the use of complex fertilizers.

Особенности формирования урожайности томата в защищенном грунте Удмуртской Республики РЕЗЮМЕ Актуальность. Большим резервом в увеличении производства томатов для разных периодов выращивания и целей использования являются новые высокопродуктивные сорта и гетерозисные гибриды. В связи с этим одним из важных условий является максимальное соответствие вновь создаваемых сортов и гибридов современным технологиям, позволяющим получать конкурентоспособную продукцию. В дополнение к основным показателям (высокая урожайность, скороспелость), важны такие сортовые особенности, как транспортабельность плодов, высокие вкусовые качества (особенно гибриды салатного типа), внешний вид, устойчивость к основным болезням и технологичность. В последние годы в культуре томата и других овощных культур выращиваются в основном гибриды первого поколения F1 и линии (результат целевого отбора), реже популяции. Уже более десяти лет в промышленном тепличном овощеводстве выращиваются только гибридные сорта. Материал и методы. В статье представлены результаты 7-летних исследований по изучению урожайности, ее структуры и качества плодов индетерминантных гибридов томата. Исследования по изучению урожайности и качеству плодов индетерминантных гибридов томата проводили в 2011-2017 годах в АО «Тепличный комбинат «Завьяловский» Удмуртской Республики. Результаты. Высокой урожайностью отличились гибриды томата F1 Измаил, F1Макарена, F1 Булава, F1 Жеронимо и F1 Старбак. Этот показатель составил соответственно: 34,5 кг/м 2 ; 33,1 кг/м 2 ; 32,3 кг/м 2 ; 32,0 кг/м 2 и 31,2 кг/м 2. Томаты F1 Якиманка, F1 Форонти, F1 Старбак, F1 Таганка и F1 Булава выделились по крупноплодности. В плодах F1 Измаил F1 Очаков, F1 Мариачи, F1 Кохава витамина С содержалось более 30 мг/100 г. Содержание нитратов в плодах томата за годы исследований было невысоким, находилось в пределах ПДК. Ключевые слова: томат, гибрид, защищенный грунт, урожайность, качество плодов, Удмуртская Республика.

In agriculture, the use of microbiological fertilizers is becoming more and more widespread. The presence of microorganisms in them allows improving soil fertility, increasing the productivity of crops, while ensuring the cultivation of environmentally friendly products. There is a wide variety of microbiological fertilizers, so determining the type of preparation for garden strawberries when grown in the conditions of the Udmurt Republic is relevant. The purpose of the research: a comparative assessment of the effect of various types of microbiological fertilizers on the productivity of garden strawberries. Materials and Methods. Studies on the effect of microbiological fertilizers on the yield and its structure of garden strawberries were carried out on the territory of Vostochny LLC, Zavyalovsky District, Udmurt Republic. In 2016, 2018 studies were carried out on the feeding of garden strawberries of the Darenka variety of the first and third years of fruiting with microbiological fertilizers on soddy-medium-podzolic medium-loamy soil. The scheme of the experiment included the following options: Water (control), Baikal EM 1, Emix, Humat EM. The total area of the plot is 2,9 m 2 . The accounting area of the plot is 1,8 m 2 . Placement of variants by a systematic method, in six-fold repetition. Results. Harvesting was carried out in five terms. Studies have proven the positive effect of the studied microbiological fertilizers on plant productivity. The highest yield of berries was 833,6 g/m 2 , which was obtained using Baikal EM 1. The largest berry was obtained in 2016, also when treated with Baikal EM 1, and amounted to 145 g. lo to increase the number of berries from the bush. So, in 2016 their number was 45,2; in 2018 -42,0 pieces.
