В статье представлены результаты исследований влияния некорневой обработки посевов растворами комплексных удобрений с микроэлементами в хелатной форме Азосол 36 Экстра и Акварин 5 на биохимический состав и кормовую ценность биомассы раннеспелого и среднераннего гибридов кукурузы на различных уровнях корневого питания. Установлено, что на содержание сырого протеина большее влияние оказали минеральные удобрения: содержание сырого протеина в фитомассе раннеспелого гибрида кукурузы увеличилось в среднем на 1,65 %, а среднераннего – на 1,76 %. Положительное влияние на накопление сырого протеина оказала обработка посевов удобрениями с микроэлементами в фазу пяти листьев кукурузы и бинарное применение. При обработке посевов удобрением Акварин 5 отмечается уменьшение сырой клетчатки в фитомассе, а более эффективным было двукратное опрыскивание посевов. Фолиарная обработка комплексными удобрениями с микроэлементами способствовала увеличению содержания сырого жира на 0,10-0,34 %. Какой-либо определенной закономерности в зависимости от вида микроудобрений по влиянию на зольность биомассы и содержание БЭВ не выявлено. На фоне естественного почвенного плодородия больший сбор переваримого протеина получен при двукратном применении микроэлементных удобрений, а на улучшенном агрофоне – при обработке посевов в фазу пяти листьев кукурузы. На обоих фонах минерального питания некорневая обработка Азосол 36 Экстра способствовала получению зеленой массы, лучше обеспеченной переваримым протеином, и выявлено преимущество обработки комплексными удобрениями в фазу пяти листьев и двукратного применения. При обработке посевов Азосол 36 Экстра прибавка кормовых единиц составила 8,1-10,1 %. AGRICULTURAL TECHNIQUES AND BIOCHEMICAL COMPOSITION OF CORN The article presents the research results of the influence of foliar treatment with solutions of complex fertilizers with microelements in chelated form (Azosol 36 Extra and Aquarin 5) on the biochemical composition and feeding value of biomass in early-season and middle-early corn hybrids at different levels of root nutrition. It was found that the content of crude protein was more influenced by mineral fertilizers: the content of crude protein in the phytomass of early-season hybrid corn increased by an average of 1.65 %, and the middle-early – by 1.76 %. A positive effect on the crude protein accumulation was provided by the treatment of crops with fertilizers with microelements in the five-leaf phase of corn and binary application. When treating crops with Aquarin 5 fertilizer, there was a decrease of crude fibre in the phytomass; the double crop spraying was more effective. Foliar treatment with the complex fertilizers with microelements contributed to an increase in the crude fat content by 0.10-0.34 %. No specific pattern was found, depending on the type of microfertilizers, on the effect on the biomass ash-content and the nitrogen-free extractive substances (NFE) content. Against the background of natural soil fertility, a greater collection of digestible protein was obtained with a double application of microelement fertilizers, and against the improved agricultural background – with the treatment of crop in the five-leaf phase of corn. Against both backgrounds of mineral nutrition, foliar treatment with Azosol 36 Extra contributed to obtaining a green mass better provided with digestible protein; and the advantage of treatment with complex fertilizers in the five-leaf phase and the double application was revealed. When treating crops with Azosol 36 Extra, the increase in feed units was 8.1-10.1 %.

The expediency of fusarium resistant lupines usage in organic farming for improving soil fertility and producing high protein feed for livestock is justified in this article. Organic production excludes the use of mineral fertilizers and pesticides. In these circumstances, increases the value of cultures that positively affect the fertility of soils and their phytosanitary status. These crops include annual fodder lupine (yellow, white and angustifolia), especially varieties that are resistant to disease. Having the highest nitrogen-fixing ability among annual legume crops, lupins, depending on the type and conditions of cultivation, can accumulate from 80 to 300 kg/ha of environmentally pure symbiotic nitrogen in biomass. Plowing the green mass (30-45 t/ha) is equivalent to the corresponding amount of manure or introduction of 5-7 t/ha of ammonium nitrate. 30 kg/ha of phosphorus and 50 kg/ha of potassium are entering the soil with plant remains. Therefore, lupine provides itself with nutrients and still leaves up to 150 kg/ha of nitrogen in the soil after harvesting for subsequent crops in crop rotation. In organic production, fusariosis resistant varieties of lupines are also interesting as a source of high protein feeds for livestock. They are building up to 60 t/ha of biomass, which contains more than one ton of digestible protein. In grain of the fodder varieties contains 40-52% of crude protein, 5.5-6.0% of fat, 10-12% of sugar. The characteristic of fusarium resistant varieties of lupins (yellow, white and angustifolia), created in the NSC "Institute of Agriculture NAAS" and included in the Register of Plant Varieties of Ukraine is presented in this article. These varieties are practically not affected by fusariosis under the production conditions and do not require the use of fungicides during the growing season. They can be grown in crop rotation with a return period of 2-3 years, whereas for unstable it took 6-7 years. Because of the inability to use in organic farming fungicide to prevent crop losses from anthracnose, it is necessary to use predominantly angustifolia lupine varieties, which are now more tolerant to this disease, prevent sowing of infected seeds and adhere to crop rotation. Fusarium-resistant varieties of lupins are suitable for cultivation in poucous and sown crops, and in mixtures with other crops.

В статье представлены результаты исследований по влиянию внекорневой обработки посевов растворами комплексных удобрений с микроэлементами в хелатной форме Азосол 36 Экстра и Акварин 5 на элементы структуры и урожайность зерна раннеспелого и среднераннего гибридов кукурузы на различных уровнях корневого питания. В вариантах без минеральных туков при применении комплексных удобрений в фазу 5 листьев количество зерен в початке возросло на 7,0-9,0, а при двукратной обработке на 8,0-9,9 и большой разницы по гибридам не отмечено. На удобренном агрофоне обработка посевов в фазу пяти листьев кукурузы микроудобрениями позволила увеличить озерненность початка раннеспелого гибрида Ладожский 191 МВ на 7,2-7,5, а двукратное применение повышало озерненность початка на 7,8-8,1. При обработке посевов среднераннего гибрида Азосол 36 Экстра прирост полноценных зерен составил 3,0-3,9, причем большее количество зерен сформировалось при применении микроудобрения в фазу пяти листьев кукурузы. Акварин 5 способствовал увеличению количества зерен в початке на 4,5-5,6, а лучшие результаты получены при двукратном его применении. При внекорневой обработке посевов раннеспелого гибрида комплексными микроэлементными удобрениями в вариантах без минеральных туков масса зерна початка увеличилась на 6,4-11,1 при небольшом преимуществе использования Акварин 5 . Применение Азосол 36 Экстра на посевах гибрида Роналдинио на естественном агрофоне позволило увеличить массу зерна с початка на 8,3-9,7, обработка Акварин 5 на 11,1-13,2, причем большие прибавки получены при двукратном применении хелатированного удобрения. Бинарное применение Азосол 36 Экстра на посевах раннеспелого гибрида Ладожский 191 МВ в условиях улучшенного корневого питания способствовало получению с початка дополнительно 8,2 зерна. Обработка в фазу пяти листьев и двукратное применение Акварин 5 увеличивало массу зерна одного початка на 8,6-8,7. На посевах среднераннего гибрида преимущество было также за микроудобрением Акварин 5 . Применение его в фазу пяти листьев увеличивало массу зерна початка на 9,1, а двукратное использование на 10,1. Азосол 36 Экстра обеспечил меньшие прибавки зерна 5,2-6, 2, причем разница по срокам обработки незначительная. Перспективным для повышения урожайности зерна кукурузы является использование комплексного удобрения с микроэлементами в хелатной форме Акварин 5 в фазу пяти листьев и двойная внекорневая обработка, способствующая увеличению сбора зерна с единицы площади на неудобренном агрофоне на 9,6-12,4, а при улучшении условий корневого питания на 7,7-8,8.The article presents the results of studies on the effect of foliage treatment of crops with solutions of complex fertilizers Azosol 36 Extra and Aquarin 5 with micro-elements in chelate form on the structural elements and grain productuvity of early ripening and medium early maize hybrids at various levels of root nutrition. In the variants without mineral fertilizers, after applying complex fertilizers in the 5-leaf phase, the number of grains in the cob increased by 7.09.0, and after double treatment - by 8.09.9, and there is no big difference in hybrids notably. On the fertilized soil, the treatment of crops in the 5-leaf phase of corn with micronutrient fertilizers allowed to increase the number of grains on the cob of the early ripening hybrid Ladoga 191 MB by 7.2-7.5, and a double application increased the number of grains on cob by 7.8-8.1 When treating the crops of the mid-early hybrid Azosol 36 Extra, the growth of full-fledged grains amounted to 3.0-3.9, and a greater number of grains were formed when microfertilizers were applied in the 5-leaf phase. Aquarin 5 contributed to an increase in the number of grains on the cob by 4.5-5.6, and the best results were obtained with its double use. After foliar treatment of early ripening hybrid crops with complex microelement fertilizers in the variants without solid mineral fertilizer, the weight of corn cobs increased by 6.4-11.1 with a slight advantage of using Aquarin 5.The use of Azosol 36 Extra on the crops of the Ronaldinio hybrid in a natural soil made it possible to increase the weight of grain from the cobs by 8.3-9.7, treatment with Aquarin 5 - by 11.1-13.2, with large increases obtained after the double use of chelated fertilizer. The binary use of Azosol 36 Extra on the crops of the early ripening Ladoga hybrid 191 MV under conditions of improved root nutrition contributed to an additional 8.2 of grain from a cob. Treatment in the 5-leaf phase and the double use of Aquarin 5 increased the weight of the grain of one cob by 8.6-8.7. In the crops of the mid-early hybrid, the advantage was also for the Aquarin 5 microfertilizer. Its use in the 5-leaf phase increased the weight of the cob grain by 9.1, and its double use by 10.1. Azosol 36 Extra provided smaller grain increments - 5.2-6.2, moreover, the difference in treatment time was not significant. A promising way to increase the productivity of corn grain is to use complex fertilizer with microelements in the chelate form Aquarin 5 in the 5-leaf phase and double foliar treatment, which contributes to an increase in grain harvest from a unit area on an unapproved agricultural background by 9.6-12.4, and with the improvement of root nutrition conditions - by 7.7-8.8.

AbstractThe aim of this work was to study the effect of the contemporary administration, in separate troughs, of two diets differing in digestible energy (DE) and crude fibre (CF) content, on the performance of lactating rabbit does. At the first mating (130 days of age and 3·8 kg), 54 nulliparous rabbit does (New Zealand) were assigned to the control group offered a conventional lactation diet (diet C: 188 g crude protein (CP) per kg dry matter (DM) and 11·43 MJ DE per kg DM); whilst another 54 rabbit does were offered at the same time, in separate troughs, diet E (203 g CP per kg DM and 12·66 MJ DE per kg DM) and diet F (178 g CP per kg DM and 10·73 MJ DE per kg DM). The contemporary administration of two diets did not significantly affect food intake. However, the rabbit does in group F + E, due to the greater consumption of diet E (approx. 0·76 of the total), consumed more digestible protein (DP) both during the first (14·40 v. 13·44 g/day per kg M0·75 and 80·1 v. 73·5 g/day per kg M0·75, respectively for days 1 to 21 and days 22 to 35) and subsequent lactations (15·37 v. 14·35 g/day per kg M0·75 and 82·6 v. 76·5 g/day per kg M0·75 respectively for days 1 to 21 and days 22 to 35). Also the DE intake was higher for the rabbit does of group F + E during the 22- to 35-day period (6708 v. 6361 kJ/day and 6918 v. 6620 kJ/day respectively for primiparous and multiparous). The improved performance of rabbit does given two different diets does not justify the extra time involved in such a technique, as the intake of diet E was constant during the experimental period and was not influenced by the different energy requirements during lactation.

Nutritious value of great (Cucurbita maxima) and musky (Cucurbita moschata) pumpkin pulp has been widely investigated, but chemical and qualitative analysis of pulp of oil pumpkin fruits has been superficial so far. The aim of two years research – to investigate the influence of compost/organic mulch to the quality of organically grown oil seed pumpkin (Cucurbita pepo) fruit quality. In 2013–2014, in Kaunas district farm, oil seed pumpkins cultivars 'Heracles', 'Hamlet', 'Danaja' were grown for research. The aim of two years research – to investigate the influence of compost/organic mulch to the quality of organically grown oil seed pumpkin fruit. Pumpkin seedlings were mulched with 5 and 10 cm thick layer of compost mulch. Standard methods were applied to identify the following: dry matter, soluble dry matter, crude protein, crude fibre and amounts of MADF, NDF, ADF fibre and crude in the pumpkin flesh. The results have determined that 5 and 10 cm compost mulch layer had a significant effect on the amount of dry matter in the pumpkin flesh. Basically, mulching has increased the amount of soluble dry matter in the pumpkin flesh. Crude protein accumulation in the fruit flesh was essentially affected by 5 cm thick layer of compost. Mulching with 5 and 10 cm compost layer has significantly increased the amount of crude fibre in 'Hamlet' and 'Heracles' cultivars. 5 and 10 cm compost mulch had a significant effect on the amount of crude ash. According to the researched indicators set parameters in ecologic system of the researched oil-seed pumpkins, the best cultivator to be grown with organic mulching is 'Hamlet'.

Background: Utilization of wild legumes has received prime importance in the recent past to compensate the scarcity of protein-rich foods as well as to tackle the protein energy malnutrition. Ripened split beans of Canavalia maritima devoid of seed coat and testa serve as traditional nutraceutical source for the coastal dwellers of Southwest India. Objective: The present study projects proximal and functional attributes of uncooked and cooked ripened split beans of C. maritima to be used in the preparation of functional foods. Methods: Proximal properties (moisture, crude protein, total lipids, crude fibre, carbohydrates and calorific value) and functional properties (protein solubility, gelation capacity, water-absorption, oilabsorption, emulsion qualities and foam qualities) of split beans were evaluated by standard methods. Results: Cooking did not significantly changed the crude protein, total lipids, ash, carbohydrates and calorific value, while it significantly increased the crude fibre. The protein solubility, water-absorption capacity, foam capacity and foam stability were significantly higher in uncooked than cooked beans. The cooked beans were superior to uncooked beans in least gelation concentration, low oil-absorption capacity, emulsion activity and emulsion stability. Conclusion: The functional properties of split bean flours were influenced by the proximal components like crude protein, total lipids and crude fibre. The energy-rich ripened split beans of C. maritima can serve as a new potential source for production of value added functional foods owing to their rich protein, rich carbohydrates, low-lipid and potential bioactive attributes.

Smoke-drying Clarias gariepinus (catfish) provides animal protein and a source of livelihood in Lagos, Nigeria. Changes occurring to seasonal and mineral compositions of smoke-dried catfish using local Traditional Drum Kiln (TDK) and a newly constructed Eco-Friendly Kiln (EFK) fitted with a flame, drying and electronic components was carried out in this study. The smoke-drying process was carried out in both wet and dry seasons and smoke-dried catfish samples stored at ambient and adjusted refrigerated temperatures of 28 and 4 0C. The smoke-drying procedure was  standardized at 60 - 80 0C and kiln lasted 24 ± 3 hours. Moisture content results showed a significant difference when the catfish samples were smoke-dried using TDK and EFK and stored in ambient and controlled temperatures in both wet and dry seasons while crude protein, lipid, ash and crude fibre values were significantly different when stored only in dry season. Mineral elements phosphorus, sodium, copper, magnesium and iron showed a significant difference when stored at both temperatures and seasons using both kilns. Mineral elements were found to be most stable in smoke-dried catfish samples when stored at controlled temperatures. This work proved that standardizing smoke-drying process using both kilns resulted in good quality smoke-dried catfish but showed that higher biochemical values were obtained when EFK is used. Key words: Nigeria, Smoke-drying Kilns, Seasons, Ambient, Controlled Temperatures

Rice bean, a lesser known pulse, has excellent nutritive value. The seed yield of the crop is higher as compared to other pulses of the Vigna family. In the present study thirty diverse rice bean genotypes were evaluated for nutritional and morpho-physiological characteristics for selecting overall superior genotypes. Variations were observed for crude protein (16.1–19.12%), carbohydrates (59.28–76.89%), ascorbic acid (0.19–0.80 mg/100 g), crude fibre (4.23-6.0%), limiting amino acids, namely tryptophan (0.85–2.42 g/16 g N) and methionine (0.52–0.67 g/16 g N), and ether extract (0.57–2.13%). Anti-nutritional factors, such as total phenolics, total tannins, condensed tannins, hydrolysable tannins and α-amylase inhibitor, also varied to a considerable extent. The cumulative grading of the genotypes based upon nutritional and morpho-physiological attributes revealed that the genotypes JCR-76, IC-137200, IC-140796 and IC-137189 were nutritionally superior genotypes for consumption.
