Purpose. To study the features of the productivity formation of broccoli hybrids depending on the methods of application of “5 element” nanofertilizer in the conditions of the Western Forest-Steppe of Ukraine.Methods. Field, laboratory, statistical.Results. With the introduction of “5 element” nanofertilizer, the head diameter of the ‘Batavia F1’ hybrid increased from 16.6 (var. 2) to 18.3 cm (var. 8), while in the control this indicator was 15.9 cm. The biggest head diameter in the hybrid ‘Orantes F1’ 18.9 and 18.7 cm was noted with foliar feeding with “5 element” nanofertilizer in the phase of 4–6 leaves + beginning of head formation + 10–12 days after the beginning of head formation and in the phase of the beginning of head formation + 10–12 days after the beginning of head formation. Accordingly, in the aforementioned variants, the head mass was 901 and 863 g, which is higher than the control (without treatment) by 166 and 128 g, or 22.3 and 17.4%.The highest yield of the ‘Batavia F1’ hybrid was obtained in 8 and 7 variants of the experiment – 33.5 and 31.9 t/ha, respectively, the yield increase was 5.2 and 3.6 t/ha, or 18.4 and 12.7%. In the hybrid ‘Orantes F1’ the highest yield (37.1 t/ha) was recorded when applying the “5 element” nanofertilizer in the 8th variant of the experiment, which is 6.6 t/ha higher than the control, or 21.6%. Compared to the ‘Batavia F1’ hybrid, the yield in this variant of the ‘Orantes F1’ hybrid was 3.6 t/ha, or 9.7%. The diameter and weight of the head, as well as the yield of the hybrid ‘Orantes F1’ were larger compared to the hybrid ‘Batavia F1’, due to its biological characteristics. A strong correlation (r = 0.97 and 0.96) was revealed between the yield and the diameter of the broccoli head in the ‘Batavia F1’ and ‘Orantes F1’ hybrids. The quality indicators of broccoli (dry matter, sum of sugars and vitamin C) in the ‘Orantes F1’ hybrid were higher compared to the ‘Batavia F1’ hybrid. A tendency towards a decrease in the concentration of nitrates in the heads of broccoli with an increase in the number of treatments with nanofertilizer “5 element” was revealed. The concentration of nitrates in the ‘Orantes F1’ hybrid was lower in all variants of the experiment in comparison with the ‘Batavia F1’ hybrid. The concentration of nitrates in the heads of broccoli in all variants of the experiment did not exceed TLV (400 mg/kg wet weight).Conclusions. With an increase in the number of foliar treatments with “5 element” nanofertilizer, the yield increased and the quality of broccoli hybrids improved. It was revealed that the yield of the ‘Orantes F1’ hybrid in all variants of the experiment was higher in comparison with the ‘Batavia F1’ hybrid. When applying nanofertilizer “5 element” in three stages – foliar feeding in the phase of 4–6 leaves + beginning of head formation + 10–12 days after the beginning of head formation – we got the highest yield of broccoli in the hybrid ‘Orantes F1’ – 37.1 t/ha, an increase over the control variant (without fertilizers) was 6.6 t/ha, or 21.6%. The ‘Batavia F1’ hybrid had a yield of 33.5 t/ha, an increase over the control variant – 5.2 t/ha, or 18.4%. | Мета. Вивчити особливості формування продуктивності гібридів капусти броколі залежно від способів застосування нанодобрива «5 еlement» в умовах Західного Лісостепу України.Методи. Польовий, лабораторний, статистичний.Результати. За внесення нанодобрива «5 еlement» збільшувався діаметр головки в гібрида ‘Batavia F1’ від 16,6 (вар. 2) до 18,3 см (вар. 8), тоді як на контролі цей показник становив 15,9 см. Найбільший діаметр головки в гібрида ‘Orantes F1’ 18,9 та 18,7 см відзначено за позакореневого підживлення нанодобривом «5 еlement» у фазі 4–6 листків + початок формування головки + через 10–12 діб після початку формування головок та у фазі початок формування головок + через 10–12 діб після початку формування головок. Відповідно у вищезгаданих варіантах маса головок становила 901 та 863 г, що вище за контроль (без обробки) на 166 та 128 г, або 22,3 та 17,4%. Найвищу врожайність капусти броколі гібрида ‘Batavia F1’ одержано у 8 та 7 варіантах досліду – 33,5 та 31,9 т/га відповідно, приріст урожаю становив відповідно 5,2 та 3,6 т/га, або 18,4 та 12,7%. У гібрида ‘Orantes F1’ найбільшу врожайність (37,1 т/га) відзначено за внесення нанодобрива «5 еlement» у 8 варіанті досліду, що вище за контроль на 6,6 т/га, або 21,6%. Порівняно з гібридом ‘Batavia F1’ урожайність на цьому варіанті у гібрида ‘Orantes F1’ була більшою на 3,6 т/га, або 9,7%. Діаметр та маса головки, а також урожайність у гібрида ‘Orantes F1’ були більшими, порівняно з гібридом ‘Batavia F1’, що зумовлено його біологічними особливостями. Виявлено сильний кореляційний зв’язок (r = 0,97 та 0,96) між урожайністю та діаметром головки капусти броколі в гібридів ‘Batavia F1’ та ‘Orantes F1’. Якісні показники капусти броколі (суха речовина, сума цукрів та вітамін С) у гібрида ‘Orantes F1’ були вищими порівняно з гібридом ‘Batavia F1’. Виявлено тенденцію до зменшення концентрації нітратів у головках капусти броколі зі збільшенням кількості обробок нанодобривом «5 еlement». Концентрація нітратів у гібрида ‘Orantes F1’ була меншою в усіх варіантах досліду, порівняно з гібридом ‘Batavia F1’. Уміст нітратного азоту в головках капусти броколі в усіх варіантах досліду не перевищував ГДК (400 мг/кг сирої маси).Висновки. Зі збільшенням кількості позакореневих обробок нанодобривом «5 еlement» підвищувалась урожайність та поліпшувалася якість продукції гібридів капусти броколі. Виявлено, що врожайність гібрида ‘Orantes F1’ у всіх варіантах досліду була  більша, порівняно з гібридом ‘Batavia F1’. За внесення нанодобрива «5 еlement» у три етапи – позакореневе підживлення у фазі 4–6 листків + початок формування головки + через 10–12 діб після початку формування головок –  одержали найбільшу врожайність капусти броколі в гібрида ‘Orantes F1’ – 37,1 т/га, приріст до контролю (без добрив) становив 6,6 т/га, або 21,6%. У гібрида ‘Batavia F1’ урожайність становила 33,5 т/га, приріст до контролю – 5,2 т/га, або 18,4%.

Purpose. To determine the efficiency of growing soybean varieties ‘Ustia’, ‘Cordoba’, ‘Estafeta’ depending on the influence of microfertilizers and growth regulators.Methods. Field, laboratory.Results. The article presents the results of studying the efficiency of growing different varieties of soybeans. It was found that in the cultivar ‘Ustia’ the best values of assimilation of photosynthetically active radiation were obtained for the applications of Yara Vita Mono Molitrak in the budding phase (0.25 l/ha) with growth regulator Radostym, and Yara Vita Mono Molitrak in the budding phase (0.25 l/ha) + in the flowering phase (0.25 l/ha) with two studied growth regulators. Similar patterns of the utilization rate of photosynthetic radiation were obtained for the ‘Cordoba’ and ‘Estafeta’ varieties. According to the indicators of the energy balance, the complex use of micronutrient fertilizers and growth regulators in any case pays off with an increase in the yield, which means it is energetically expedient. The maximum coefficients of energy efficiency in the ‘Ustia’, ‘Cordoba’ and ‘Estafeta’ varieties were obtained with the introduction of micronutrient fertilizers Yara Vita Mono Molitrak in the budding phase (0.25 l/ha) + in the flowering phase (0.25 l/ha) and growth regulators Biosyl and Radostym. However, the use of growth regulators separately does not always provide an economic return on investment. In particular, in the variant without Yara Vita Mono Molitrak microfertilizer, the ‘Cordoba’ variety received 28 873 UAH/ha of net profit, while the introduction of growth regulators did not pay off, since there was no significant increase in the yield, and with the use of growth regulators Biosyl and Radostym net profit was within 28824–29179 UAH/ha. In general, the use of micronutrient fertilizer Yara Vita Mono Molitrak with growth regulators Radostim and Biosyl ensu­red guaranteed yield increase.Conclusions. When gro­wing ‘Ustia’, ‘Cordoba’ and ‘Estafeta’ varieties from an energy point of view, it is better to use Yara Vita Mono Molitrak microfertilizer in the budding phase (0.25 l/ha) with the growth regulator Radostym. Under these conditions, the obtained energy efficiency ratio was 3.24; 3.41 and 3.45, and the profit was 31503, 34072 and 34649 UAH/ha, respectively | Мета. Визначити ефективність вирощування сортів сої ‘Устя’, ‘Кордоба’, ‘Естафета’ залежно від впливу мікродобрив та регуляторів росту. Методи. Польові, лабораторні.Результати. У статті наведено результати вивчення ефективності вирощування різних сортів сої. Установлено, що в сорту ‘Устя’ кращі значення засвоєння фотосинтетично активної радіації отримано для варіантів застосування Yara Vita Моно Молітрак у фазі бутонізації (0,25 л/га) з регулятором росту Радостим, та Yara Vita Моно Молітрак у фазі бутонізації (0,25 л/га) + у фазі цвітіння (0,25 л/га) з обома досліджуваними регуляторами росту. Аналогічні закономірності коефіцієнту використання фотосинтетичної радіації були отримані й для сортів ‘Кордоба’ та ‘Естафета’. Згідно з показниками енергетичного балансу, комплексне застосування мікродобрив та регуляторів росту в будь-якому разі окупається приростом урожаю, а отже є енергетично доцільним. Максимальні коефіцієнти енергетичної ефективності в сортів ‘Устя’, ‘Кордоба’ та ‘Естафета’ отримано за внесення мікродобрива Yara Vita Моно Молітрак у фазі бутонізації (0,25 л/га) + у фазі цвітіння (0,25 л/га) та регуляторів росту: Біосил та Радостим. А от застосування регуляторів росту окремо не завжди дає змогу отримати економічну окупність. Зокрема, у варіанті без мікродобрива Yara Vita Моно Молітрак у сорту ‘Кордоба’ отримано 28873 грн/га чистого прибутку, тоді як внесення регуляторів росту не окупилось, оскільки не було значного приросту врожаю, а за застосування регуляторів росту Біосил та Радостим чистий прибуток був у межах 28824–29179 грн/га. Загалом застосування мікродобрива Yara Vita Моно Молітрак з регуляторами росту Радостим та Біосил забезпечувало гарантованого приросту врожаю.Висновки. За вирощування сої ‘Устя’, ‘Кордоба’ та ‘Естафета’ з енергетичного пог­ляду ліпше застосовувати мікродобриво Yara Vita Моно Молітрак у фазі бутонізації (0,25 л/га) з регулятором росту Радостим. За таких умов отримано коефіцієнт енергетичної ефективності становив 3,24; 3,41 і 3,45, а прибуток 31503, 34072 і 34649 грн/га відповідно.

Purpose. Morphological and organoleptic evaluation of oyster mushroom strains for selection of highly productive cultivars assortment with valuable consumer properties for winter and summer cultivation and suitability for sale in fresh or processed form were investigated.Methods. The scheme of the experiment included six strains of oyster mushrooms belonging to two species: Pleurotus ostreatus (5 strains: 2301, Z, 2316, 2456, 431) and P. pulmonarius (2314). Laboratory, laboratory-industrial and statistical methods are used.Results. The dynamics of agrochemical parameters of substrates obtained by the method of aerobic fermentation in the high layer proved their optimality according to the main criteria and compliance to regulatory documentation. The biological efficiency of the strains was in the range of 40–78.9%. The highest weight of clusters was found in the “summer” strain 431 (430.7 g). The highest weight of the fruiting body was determined for the strain 2301 (15.2 g), the lowest – for the 2456 (3.3 g).Conclusions. The values of biological efficiency of strains was determined. The highest average values for the first flush of fruiting had strains 2316 (78.9%) from the “winter” group (A) and 431 (78.4%) from the “summer” group  (B). According to the results of statistical analysis, significant differences were revealed between the studied strains in the main morphological indicators of clusters. It was found that the mass of clusters of «winter» cultivars is much less dependent on the strain type (220.8–273.4 g) than that of «summer» cultivars (83.4–430.7 g). The index of the asymmetry coefficient of the cluster, which can be useful for calculating the required container sizes was proposed. It was determined that the morphological features of fruiting bodies had significant differences in all studied parameters.  In particular, the A group strains differed in size and weight. It was proposed the index of weight loss of the crop coefficient, which shows the ratio between the cap and stipe of the fruiting body and make it possible to predict the amount of mushroom raw material that will be sold in the form of caps, and the amount of raw material that can be processed into minced mushroom, powder and others. The best coefficient was obtained for the fruiting bodies of strain 2314 (0.87), and the worst – for 2456 (0.59), which, accordingly, is not recommended for sale by individual fruiting bodies. It was found that the fruiting bodies of high-yielding strains 2316 and 431 had a number of organoleptic defects. | Мета. Провести морфологічну та органолептичну оцінку штамів гливи для добору асортименту високопродуктивних і цінних за споживчими властивостями культиварів для зимового й літнього культивування та придатності до реалізації у свіжому або переробленому вигляді.Методи. Схема досліду включає 6 штамів гливи, що належать до двох видів: Pleurotus ostreatus (5 штамів: 2301, Z, 2316, 2456, 431) і Pleurotus pulmonarius (2314). Використано лабораторний, лабораторно-виробничий та статистичний методи досліджень.Результати. Динаміка агрохімічних показників субстратів, отриманих методом аеробної ферментації у високому шарі, засвідчила їхню оптимальність за основними критеріями та відповідність нормативній документації. Біологічна ефективність штамів знаходилася в інтервалі 40–78,9%. Найбільшу масу зростків установлено в «літнього» штаму 431 (430,7 г). Найбільшу масу плодового тіла визначено для штаму 2301 (15,2 г), найменшу – для 2456 (3,3 г).Висновки. Визначено показники біологічної ефективності штамів. Найвищі середні значення за першою хвилею плодоношення мали штами 2316 (78,9%) із групи «зимових» (А) і 431 (78,4%) із групи «літніх» (В). За результатами статистичного аналізу встановлено суттєві відмінності між досліджуваними штамами за основними морфологічними показниками зростків. Виявлено, що маса зростків «зимових» культиварів значно менше залежить від штамової приналежності (220,8–273,4 г), ніж «літніх» (83,4–430,7 г). Запропоновано показник коефіцієнт асиметрії зростка, який може бути корисним для розрахунку необхідних розмірів тари. Виявлено, що морфологічні ознаки плодових тіл мали суттєві відмінності за всіма дослідженими параметрами. Зокрема, штами групи А відрізнялися більшими розмірами й масою. Запропоновано показник – коефіцієнт утрати маси врожаю, який показує співвідношення між шапинкою й ніжкою плодового тіла та дає змогу спрогнозувати кількість грибної сировини, яку буде реалізовано у вигляді шапинок, та кількість сировини, яку можна переробити у грибний фарш, порошок та ін. Найкращий коефіцієнт отримано для плодових тіл штаму 2314 (0,87), а найгірший – 2456 (0,59), який, відповідно, не рекомендуємо до реалізації окремими плодовими тілами. Установлено, що плодові тіла високопродуктивних штамів 2316 і 431 мали низку органолептичних недоліків.
