Plum fruits have harmonious taste qualities and valuable biochemical composition. Plum is characterized by a low content of vitamin C, but in combination with high concentrations of phenolic compounds, is of great value as a source of antioxidants. The problem of improving the quality and ensuring the safety of food products is not only relevant, but is also one of the most important economic problems at the present stage. The aim of the research was to study the quality and safety of fresh plums sold in retail trade. It has been established that in the stores of the retail trade network «Dixi» (Chelyabinsk city) fresh plums are being realized, not only satisfying the requirements of the quality of the current regulatory documents, but also products belonging to a category such as «waste». Excellent organoleptic indicators (attractive appearance, bright color scale) of the studied products were not always consistent with high nutritional value. Thus, benign fractions of the Hungarian and Renclaw plums had the most acceptable taste characteristics and high nutrient content, but due to the content of rotten fruits in the overall product sample, they should not be in free implementation. The highest commodity grade of plum mirabel established during the quality assessment did not guarantee its high nutritional value. The content in the Renclod plums and the mirabel of toxic elements (lead and cadmium) was significantly lower than the level found in the fruits of Chinese plum and Hungarian. The need for additional pre-sales preparation and sorting of the fruits of the Hungarian and Rencloid plums is identified, which will allow to increase not only the quality and safety of products, the culture of customer service, but also to extend the shelf life of commodity lots of fresh plums in general.

ABSTRACT Diet, energy density (ED) and relative condition factor (Kn ) were used to investigate the energetic assimilation of the invasive fish Hemiodus orthonops under different environmental condition of the upper rio Paraná floodplain. Samples were taken in June and September 2013 and 2014. Nutrient content was determined for sediment. The diet was combined in the Food Index (IAi%), ED was expressed in Kcal/g of dry weight and Kn was calculated by: Kn = Wt/We, where Wt is the total weight and We the expected weight. Detritus/sediment prevailed in the stomachs of specimens from Ivinhema and Baia, while Algae was the main item in Paraná, reflecting the resource availability. ED and Kn from Ivinhema specimens were the greatest, consequence of the quality of food and lower spent on searching and handling food. The Paraná specimens showed lower ED values, but higher Kn values, due to algae consumption, a nutrient-rich resource. Baia presented high aluminum concentration on the sediment and the lower pH values, which contribute to reduce the nutritional value of the detritus and the ED and Kn values of their specimens. In conclusion, H.orthonops is capable to take advantage of the resources availability in the different environments, ensuring their establishment.

Shellfish, called as kerang in Indonesia, contains animal protein that’s popular, making it as and important fisheries and marine commodity. Supported by the good taste and high nutrient content in it. Paphia undulata or Kerang  Batik, Peryglipta reticulata or Kerang Kemiri, Meretrix meretrix or Kerang Tahu, and Codakia tigerina or Kerang Madu, are consumption shells from northern coast of Java. To improve the quality of shellfish, Chlorella added as shellfish food preferences. It supported by the high nutrient content in Chlorella sp. Shellfish kept for 15 days in a basket with a sand substrate and drainage from sea. Therefore, the water quality had been controlled for the changed of salinity and water temperature. Parameters used to see the improvement shellfish quality is the color changes on visceral mass and the changes of proximate content (moisture, protein, fat, carbohydrate and ash). This study proves the color changes on visceral mass and proximate content. The color change occurs on the visceral mass and the gills. The changes of viscerall mass occurs on kerang batik from white greyish to yellow while the more clearly gills occurs on kerang madu and kemiri. Meanwhile, the change of proximate shown by the increasing of protein and moisture on all the spesies while on the otherside the decreasing of carbohydrate and ash, but the increasing of fat only occurs on kerang batik and kerang madu. The higher proximate changes occur on kerang madu, where the ammount of moisture at 71,43 ± 0,03 %, the protein at 16,55 ± 0,02 %, the fat at 1,35 ± 0,04 %, the carbohydrate at 2,9 ± 0,03 %, and the ash at 8,09 ± 0,04 %. The conclusion of this research are kerang madu has the higher positive influences by addition of Chlorella, shown by the increasing of proximate contents and the clearly of gills. Keywords : addision of Chlorella sp., changes of visceral mass, proximate, shellfish

The Impact

The chemical composition and nutritional value of alfalfa hay are influenced by: climatic conditions, soils, phase of development in the period of mowing mass, variety, technology of cultivation and harvesting, etc. Hay harvesting is associated with high nutrient losses due to leaf loss and inflorescence or significant energy consumption for artificial drying. Mechanical losses often exceed 40% or more, with more than half of them occurring in the field operations: mowing, flattening, stirring, raking and weight gain. The question of the impact of the multiplicity of technological operations on the processing of the roll by elastic working bodies when harvesting hay from alfalfa on the chemical composition has not been sufficiently studied, which was the purpose of the research.Field technological experiments were carried out on pure crops of alfalfa of the blue Vinnychanka variety in different weather conditions. The results obtained by us in the field technological experiments show that the multiplicity of cultivation of the roll in the process of harvesting alfalfa for hay and weather conditions to some extent affect its quality and nutrient content in it. Thus, the protein content in the initial mass (first experiment) was 15.61, in the hay prepared without the use of roll processing - 13.43, using a single treatment - 14.81, twice - 13.69 and three times 13.65% in dry matter.According to the results of the research, it was found that the hay harvested using single roll processing had the highest carotene content in natural mass - 32.4 mg / kg in the first and 30.4 mg / kg in the second experiments.No significant difference in the variants of experiments was observed in the content of ash and minerals, calcium and phosphorus. By all indicators of nutrient content, the technology of hay harvesting with the use of one-time processing of the roll per day was the best.

Animal manures can be used as organic fertilizer because the high nutrient content such as nitrogen (N), phosphorus (P), and potassium (K). The nutrients are needed by plants and soil for fertility. One of the animal manuresthat can be used for organic fertilizer is goat manure. Goat manure is used as organic fertilizer it contains relatively more balanced nutrients than other natural fertilizer. In addition, the goat manure is mixed with the goat urine that alsocontains high nutrients. Coconut coir dust contains high potassium so that the addition of coconut coir dust in organic fertilizer will increase the potassium content (K) in organic fertilizer. The purpose of this research was to find out theinfluence of effective Orgadec and PROMI bioactivators on the optimal time of composting and the quality of the organic fertilizer. The organic fertilizer was analyzed to determine the content of N, P, K, organic-C, C/N ratio, watercontent, and pH. The result of analysis is compared with SNI 19-7030-2004. Organic fertilizer analysis was conducted on day 0, 10, 20, 30, 40, and 50. The result of the organic fertilizer analysis with Orgadec bio-activator more effectiveand faster on the decomposition organic matter in the compost compared PROMI (<20 days). The quality of organic fertilizer with Orgadec bioactivator on day 10 and 20, while organic fertilizer with PROMI on day 20, 30, 40, and 50days was in accordance with the quality stated in SNI 19-7030-2004 (C/N ratio, levels of N, P, K, water, and organic-C).

В статье представлены результаты полевых исследований влияния видов кормовых культур и их норм высева в смешанных посевах на кормовое достоинство травостоя. Целью данного исследования являлось изучение просяно-бобовых смесей в неблагоприятных климатических условиях Предбайкалья. Исследования проводились в 20172019 годах на опытном поле Иркутского НИИСХ. Представлены результаты анализа продуктивности и питательной ценности одновидового посева проса и его смесей с пелюшкой и викой. Установлена целесообразность возделывания на зелёную массу кормовых культур в двухкомпонентных агроценозах. Изучение просяно-пелюшковых смесей показало, что соотношение компонентов 70:50 имело превосходство от 0,2 до 31,2 по всем показателям продуктивности над посевом проса в чистом виде. Совсем иная картина имела место при изучении просяно-виковых посевов, так как все ценозы по всем показателям кормового достоинства дали прибавку. Наиболее высокую прибавку обеспечил вариант просо 70 вика 50, превысивший посев проса с пелюшкой в таком же соотношение компонентов на 8,422,9, а одновидовый посев проса на 9,753,1. Самую высокую обеспеченность переваримым протеином 123,6 г в 1 корм. ед., по данным химического анализа, показала смесь проса с пелюшкой в соотношение культур 70:60, которая превзошла посев проса в чистом виде на 17,7, или в 1,3 раза. Изучение химического состава фитоценозов позволило получить данные, определяющие питательность кормов. Установлено, что содержание сырого протеина и сырой клетчатки в смешанных посевах выше, чем в одновидовом посеве проса соответственно в 1,81,9 и 2,52,6 раза. Сахарами были богаче просяно-пелюшковые смеси, а сырой золой и кальцием просяно-виковые. Выявлено, что агроценозы богаче протеином и более сбалансированы по содержанию элементов питания. The paper reports on the effect of crop species and their seeding rate on forage quality of such mixtures. The investigation was conducted at the Irkutsk Agricultural Research Institute in 20172019 and tested millet-legume mixtures under unfavorable conditions of Cisbaikalia. The analyses dealt with productivity and nutritional value of pure millet ecosystems and its mixtures with Australian winter pea and vetch. Two-component ecosystems were efficient for green mass production. Millet-Australian winter pea stands (70:50) exceeded pure millet by 0.231.2 in productivity. Millet-vetch mixtures showed increases in all the forage traits. Millet-vetch swards (70:50) exceeded millet-Australian winter pea stands (70:50) by 8.422.9 in productivity, pure millet by 9.753.1. Combination of millet with Australian winter pea (70:60) showed the highest yield of digestible protein 123.6 g per 1 feed unit, exceeding millet monoculture by 17.7, or 1.3 times. Mixtures exceeded pure stands in crude protein and fiber by 1.81.9 and 2.52.6 times, respectively. Mixtures of millet with Australian winter pea had higher content of sugars while millet-vetch swards crude ash and calcium. The ecosystems were richer in protein and more balanced in nutrient content.

Biochar produced from biomass with high nutrient content is essential for improving the quality of agricultural soils. An abundance of biomass is converted into biochar with high nutrient content, but studies on the conversion of pineapple and sago waste into biochar are still limited. This research aimed to produce biochar from pineapple leaf (PLB), sago bark (SBB), and sago pith (SPB) through the carbonization process with low temperature. The samples were carbonized using a laboratory electric oven at a low temperature of 350°C. The raw biomass and biochar produced were then subjected to elemental analysis and characterization. The mineral contents of carbonized biochar such as K, N, S, Mg, and Ca increased from those of the feedstock concentrations. For PLP, K element increased 24-fold from 2.44 ± 0.73% to 48.32 ± 9.92%, while N element increased from 6.13 ± 2.39% to 8.33 ± 5.34%. However, for both SBB and SPB, N and K nutrients increased by 2-fold. The study reveals that pineapple leaf biochar has the potentials to be used as an alternative soil amendment to elevate soil nutrient and quality.
