“…al., 2020) it is proved that in modern economic conditions it is advisable to increase the volume of use of liquid mineral fertilizers, the effectiveness of which depends to a lesser extent on the level of soil moisture. The most effective method of introducing trace elements is foliar nutrition during the growing season by spraying plants in critical phases of development (Patil et al, 2018;Panfilova et. al., 2021).…”

The purpose of the research is to determine the duration of the interphase period, total water consumption, plant height, yield and quality of sunflower seeds, depending on the characteristics of hybrids and foliar top dressing with microfertilizers. Methods. Experimental studies were conducted during 2020-2021 in the experimental field of Mykolaiv National Agrarian University (Ukraine). Results. It was determined that all the studied microfertilizers extended the duration of interfacial periods of sunflower plants. The largest total water consumption of sunflower plants (2259 m 3 /ha) was formed in the hybrid NK Kamen in the variant with foliar top dressing with microfertilizer Quantum, which was 0.9-6.5% more than in the same variant with hybrids Darius and Tutti. The highest height of sunflower plants among the hybrids submitted for study was formed by Darius -165.7-170.9 cm, which was 5.0-5.7% higher than the height of plants of the NK Kamen hybrid and 7.2-8.0% more than the height of Tutti hybrid. It was found that the highest yield of sunflower seeds (2.55 t/ha) on average over the years of research was formed in the hybrid NK Kamen in the variant with foliar top dressing with microfertilizer Quantum, which exceeded its level in the non-fertilized control by 18.6% and the average yield for all variants of the experiment by 12.3%. The highest yield of sunflower seeds (2.56 t/ha) among the hybrids submitted for study was provided by NK Kamen in 2021, which was 12.3% more than in the Darius hybrid and 6.6% more than in the Tutti hybrid. Foliar top dressing with microfertilizers significantly affected the quality indicators of seeds of the studied sunflower hybrids. The maximum fat content values (from 50.1 up to 52.7%, depending on the hybrid) were achieved by applying Quantum microfertilizer in the 5-6-leaf phase. The conditional yield of oil from seeds in this variant of nutrition is also determined to be the maximum -from 1.13 up to 1.34 t/ha, depending on the hybrid. Less effective for the growth and development of plants and the formation of their productivity was the preparation Rostok, with the introduction of which the duration of the growing season increased by 1-2 days; total water consumption increased by 29-35 m 3 /ha; the height increased by 1.1-4.6 cm; seed yield increased by 0.80-0.28 t/ ha; the content fat in seeds increased by 0.02-0.03%; oil seed yield increased by 0.12-0.15 t/ha.

“…Wheat production in Europe countries is particularly dependent on synthetic fertilizers because the use of animal manure is very limited, many of the soils are naturally low in levels of soil organic matter and there are only a few legumes present in main crop rotations that could supply symbiotically fixe nitrogen (Biel et al, 2016). Research of many foreign and domestic scientists (Ying, 2019;Hashem et al, 2019;Gamayunova and Panfilova, 2020;Panfilova et al, 2020;Müller and Behrendt, 2021;Nemea et al, 2021;Holtappels et al, 2021;Panfilova, 2021;Panfilova et al, 2021) the most effect of biologics and growth-regulating drugs on the yield and quality of agricultural crops has been proven.…”

The aim of the research was to determine the influence of varietal characteristics, pre-sowing seed treatment and irrigation on the yield of winter wheat (Triticum aestivum L.). Experimental studies were carried out in the conditions of Mykolayiv National Agrarian University (Ukraine) during 2019-2022 yrs. It was found that among the studied variety of winter wheat, the highest grain yield was distinguished by the variety ‘Ozerna’ and ‘Duma Odes’ka’. On average, for pre – sowing seed treatment and irrigation options, these variety formed yields at the level of 6.78 and 6.95 tha–1, which was higher than the grain yield of ‘Anatoliya’ variety by 4.1 up to 6.5%, and then the yield of ‘Ovidii’ variety by 3.9 up to 6.3%. It was proved that preparations for pre-sowing seed treatment contributed to the formation of more productive stems and grain mass from one ear in winter wheat plants. So, on average, over the years of research, variety and irrigation options, for the use of Azotofit-R, the number of productive stems increased by 34-74 PCs./ m2 compared to other seed treatment options. At the same time, the yield of winter wheat grain was also slightly higher with the use of Azotofit-R biologics. It was found that the use of irrigation provided an increase in grain yield by 1.66-2.19 tha–1 or 23.1-27.2%, depending on the studied winter wheat variety. At the same time, the ‘Duma Odes’ka’ variety had a higher grain yield under irrigation (8.06 tha–1), while in conditions without irrigation, a slightly higher grain yield was formed by plants of the ‘Ozerna’ variety (5.87 tha–1). On average, over the years of research, the highest yield of winter wheat grain was provided by the cultivation of the ‘Duma Odes’ka’ variety for pre-sowing seed treatment with Azotofit - R biologics and irrigation–8.38 tha–1.

“…In particular, the increase in grain yield of winter plants and economic efficiency are significantly influenced by the background of mineral nutrition, the predecessor, features of the variety, methods of soil cultivation, sowing dates, etc. [9][10][11][12][13][14]. The higher their yield, the more favorable the economic indicators will be [15][16][17][18][19][20][21].…”

Мета. Визначити основні показники економічної ефективності вирощування ячменю озимого, встановити вплив на її складові сортових особливостей та ресурсоощадного живлення з використанням сучасних біопрепаратів для позакореневих підживлень посіву рослин у основні періоди вегетації. Методи. Дослідження з чотирма сортами ячменю озимого проводили в навчально науково практичному центрі Миколаївського національного аграрного університеті на чорноземі південному. Дослід двофакторний, фактор А-сорт: 1. Достойний (стандарт); 2. Валькірія; 3.Оскар; 4. Ясон. Фактор В – позакореневі підживлення: 1. Контроль (обробка водою); 2. Азотофіт; 3. Мікофренд; 4. Меланоріз; 5. Органік баланс. Агротехніка вирощування ячменю озимого була загальноприйнятою, окрім факторів, що взято на вивчення. Усі елементи технології та визначення проводили відповідно методичних зональних рекомендацій та ДСТУ. Результати. Проаналізовано вплив добору сорту й проведення позакореневих підживлень взятими на дослідження біопрепаратами на складові чинники економічної ефективності. Встановлено, що вартість вирощеного зерна ячменю озимого істотно змінювалася і коливалась залежно від сорту, біопрепарату, фази його використання та кількості підживлень. Аналогічно за впливу зазначених заходів змінювалися й показники умовно чистого прибутку, рівня рентабельності та собівартості. Проте із залученням для підживлення біопрепаратів перші два чинники економічної ефективності збільшувалися, а собівартість вирощування одиниці продукції, навпаки, знижувалася. Найсприятливіші економічні показники забезпечувало вирощування сортів Валькірія та Оскар, а із біопрепаратів – використання Органік балансу і Азотофіту. Висновки. Встановлено, що ресурсоощадна оптимізація живлення ячменю озимого позитивно позначалась на всіх чинниках, які характеризують економічну ефективність і рентабельність вирощування цієї культури. Вони залежали і змінювалися за впливу сорту, дібраного для позакореневої обробки біопрепарату та кількості підживлень.
