The experiment was conducted in intensive apple tree plantations of knip-baum type in 2009-2011 (Braeburn variety on the dwarf rootstock M.9). The control and management of water regime of root layer on the irrigated plots were performed using tensiometry method, consisting in the creation and maintenance of an optimum range of tensiometric pressure during the vegetation period. Experimental design: 1) natural moisture content (control variant); 2) pre-irrigation soil moisture 70 % of the minimum water capacity (MWC) throughout the vegetation period; 3) pre-irrigationsoil moisture 70-80-70 % MWC 4) pre-irrigation soil moisture 80 % MWC throughout the vegetation period. Economically justified and warranted results were obtained with the differentiated assignment of irrigation dates: 70 % MWC at the beginning of the vegetation period and during the fruit ripening stage and 80 % MWC in the stage of intensive plant growth and fruit formation. In the third year of fruiting the yield was 52.6 t/ha, which is much more than with natural moisture content. The average net profit was 5 times higher than in the control variant and the level of profitability was 3.5 times higher.; Исследованы режимы капельного орошения яблоневых насаждений в условиях гумидной зоны Закарпатья. Опыт проводили в 2009-2011 годах в интенсивных яблоневых насаждениях типа книп- баум (сорт Брейберн на карликовом подвое М.9). Оперативный контроль и управление водным режимом корнеобитаемого слоя почвы на орошаемых участках проводили применяя тензиометрический метод, суть которого сводится к созданию и поддержанию в течение вегетационного периода в почве оптимального диапазона тензиометрического давления. Схема опыта: 1) естественное увлажнение (контроль); 2) предполивная влажность почвы 70 % наименьшей влагоемкости (НВ) в течение всего периода вегетации; 3) предполивная влажность почвы 70-80-70% НВ; 4) предполивная влажность почвы 80 % (НВ) в течение всего периода вегетации. Экономически обоснованные и экономически оправданные результаты получены при дифференцированном назначении сроков полива: 70 НВ в начале вегетации и во время созревания плодов и 80 % НВ в период интенсивного роста растений и налива плодов. При этом урожайность на третий год плодоношения составила 52,6 т/га, что значительно выше чем при природном увлажнении. Чистая прибыль в среднем была больше контроля в 5 раз, а уровень рентабельности производства – в 3, 5 раза. 2013-01-01T00:00:00Z https://repository.utm.md/handle/5014/24534 Foarfecele preţurilor – factor de influenţare a rezultatelor financiare ale întreprinderii agricole ZAHARCO, Silvia This paper presents the study on the financial results modification of the agricultural enterprises depending on the agricultural production price and other important factors as: sales volume, sales structure, merchandise assortment and sales cost. In order to determine the influence of these factors on the gross profit deviation it was necessary to recalculate the actual sales volume according to the trading price and unit cost during the previous period. Trading prices (or prices for agricultural products accepted by farmers) together with the prices paid by farmers for industrial products necessary for agriculture development form price scissors. The existence and maintenance of price disparity has a detrimental economic consequence, i. e. the price mechanism has a more reduced role in market regulation than it is expected. Amore reduced profit share in the agricultural prices limits the possibility to differentiate prices by their quality, i. e. it restricts the acceptance of superior quality parameters.; Lucrarea de faţă prezintă un studiu al modificării rezultatelor financiare ale întreprinderii agricole în dependenţă de preţurile de comercializare a producţiei agricole, precum şi a altor factori importanţi, cum sunt: volumul vânzărilor, structura şi sortimentul vânzărilor, costul vânzărilor. Pentru a calcula influenţa acestor factori la devierea profitului brut a fost necesar de a recalcula volumul efectiv al vânzărilor după preţul de comercializare şi costul unitar din perioada precedentă. Preţurile de comercializare (sau preţurile primite de agricultori pentru produsele agricole) în raport cu preţurile plătite de agricultori pentru produsele industriale necesare agriculturii formează foarfecele preţurilor. Existenţa şi menţinerea disparităţii preţurilor are o consecinţă economică defavorabilă, şi anume că mecanismul preţurilor are un rol mai redus în reglementarea pieţei decât cel dorit. Ponderea mai redusă a profiturilor în preţurile agricole limitează posibilitatea diferenţierii preţurilor după calitate, deci limitează acceptarea parametrilor calitativi superiori. 2013-01-01T00:00:00Z https://repository.utm.md/handle/5014/24532 Efectul acidifiantului Agrocid Super asupra unor indici clinici şi biochimici la puii de carne VOINIȚCHI, Eugen The purpose of our researches consists in evaluating the effect of the acidulant Agrocid super on the main productive indices of meat chickens. The investigations were conducted on 2 groups of chickens (a control group and an experimental group, each of 28,560 Ros-308 broiler chickens, during a period of 50 days). The preparation Agrocid super, containing organic acids (acetic, lactic, propionic and formic acids) was administered in drinking water at a concentration of 0.5 g/l in the first days of life, at the age of 10–15; 26-31 days and in the last week before slaughtering (45-50 days). The analysis of the obtained results showed the following findings: reduced morbidity of chickens from the experimental group - 8 % compared to 10.7 % (control group). The lethality rate constituted 4.94 % (experimental group) and 5.2 % (control group). At the age of 42 days the chickens which received acidulant reached a body weight by 80 g higher compared to control group. Also, some hematological and biochemical indices tended to increase because of the intensification of metabolic processes.; Scopul cercetărilor de faţă constă în evaluarea efectului preparatului Agrocid Super asupra principalilor indici de producţie la creşterea puilor de carne. Experienţele s-au efectuat pe 2 loturi (martor şi experimental a câte 28 560 de pui brolier Ros-308, pe parcursul a 50 de zile. Preparatul Agrocid Super, ce conţine acizi organici (acetic, lactic, propionic şi formic) s-a administrat cu apa de băut în cantitate de 0,5 g/l înprimele zile de viaţă ale puilor; la vârsta de 10-15 zile; 26-31 zile şi în ultima săptămînă înainte de sacrificare. În urma analizei rezultatelor obţinute s-a constatat o reducere a morbidităţii la puii din lotul experimental la nivel de 8 % faţă de10,7 % la cel martor, procentul letalităţii a constituit 4,94 % (lot experimental) şi 5, 2 % (lot martor). La vârsta de 42 de zile puii, care au primita cidifiant, au atins o greutate corporală cu 80 g mai mare faţă de puii lotului martor. S-a înregistrat o tendinţă de creştere a indicilor biochimici şi hematologici ca urmare a intensificării proceselor metabolice. 2013-01-01T00:00:00Z https://repository.utm.md/handle/5014/24530 Изучение влияния биологически активных добавок разнонаправленного действия на динамику живой массы и сохранность поросят за период выращивания ВЕРЖАК, В.; КАЛАШНИКОВ, В.; ШАПОВАЛОВ, С.; ДОЛГАЯ, М. The effect of the probiotic preparation Primix-Bionorm K, prebiotic preparation Ekomin and the sorbent Primix Alfasorb on the dynamics of body weight as well as on absolute and relative weight gain were investigated. It was found that the combined use of the above mentioned preparations had a positive effect and led to the increase of body weight by 21,95 %, absolute weight gain – by 29.1 % and relative weight gain- by 17,79 % as compared with the control group.; В статье приведены результаты изучения влияния различных схем применения пробиотического препарата «Праймикс-Бионорм-К», пребиотического препарата «Экомин» и сорбента «Праймикс Альфасорб» на динамику живой массы свиней, абсолютный и относительный прирорст. Установлено, что комплексное применение вышеуказанных препаратов было наилучшим и способствовало увеличению живой массы на 21,95 %, абсолютного прироста на 29,1 % и относительного прироста на 17,79 % относительно контрольной группы. 2013-01-01T00:00:00Z
