В статье представлены результаты трехлетних исследований по влиянию традиционных способов хранения на сохранность и качество клубней топинамбура. Полезные свойства топинамбура известны человеку на протяжении многих лет. В силу биологических особенностей использование клубней на протяжении всего календарного года довольно проблематичная задача они подвергаются грибковым заболеваниям, быстро усыхают. Поэтому целью данного исследования является определение оптимального, из традиционных способов, хранения в условиях овощехранилища. В большинстве лет исследований лёжкость топинамбура не зависит от способа хранения и изменяется от 31 до 95. Внешние наблюдения показали, что во второй год исследований наилучшую лёжкость обеспечил способ хранения клубней в мешке. В первый и третий год исследований во всех способах наблюдались загнившие клубни. Независимо от применяемого способа, клубни в процессе хранения подвергаются усушке. В большинстве лет исследований она выше при хранении насыпью на 1,7-8,2. При хранении клубней топинамбура в ящиках наблюдается наименьшее снижение содержания клетчатки 0,2-2,5, в то время как при хранении в мешке 1,1-4,3, при хранении насыпью 0,9-2,4. Хранение в ящике обеспечивало наименьшее снижение содержания водорастворимых сахаров 1,4-4,8. Наиболее оптимальным из традиционных способов является хранение в ящиках.The article presents the results of three years of research on the impact of traditional storage methods on the safety and quality of Jerusalem artichoke tubers. The beneficial properties of Jerusalem artichoke have been known for many years. Due to biological characteristics, the use of tubers throughout the calendar year is a rather problematic task - they undergo fungal diseases and quickly dry out. Therefore, the purpose of this study was to determine the optimal method of storage in a vegetable store. In most years of the research, the storability of Jerusalem artichoke did not depend on the storage method and varied from 31 to 95. External observations showed that in the second year of the research the best keeping quality was ensured by the method of storing tubers in bags. In the first and third years of the research, rotted tubers were observed under all methods of storage. Regardless of the method used, tubers were dried during storage. In most years of the research, moisture loss was higher when stored in bulk - by 1.7-8.2. When storing Jerusalem artichoke tubers in boxes, the lowest reduction in fiber content was observed - 0.2-2.5, while when stored in bags - 1.1-4.3, when stored in bulk - 0.9-2.4. Storage in boxes provided the smallest reduction in the content of water-soluble sugars - 1.4-4.8. The most optimal of the traditional methods of storage is the storage in boxes.

В условиях низкого уровня использования минеральных удобрений в земледелии в связи с высокой их стоимостью и почти полного отсутствия органических удобрений разработка и внедрение в земледельческую практику технологических приемов использования альтернативных источников органического вещества и элементов питания является актуальным направлением современного земледелия. Задача исследований заключалась в изучении последействия мелиоративных норм осадков сточных вод г. Пенза и их сочетаний с цеолитсодержащей породой на урожайность и качество растениеводческой продукции. Исследования проводились в первом агропочвенном районе Пензенской области в зернопаропропашном севообороте в период с 2014 по 2019 гг. Установлено, что наиболее существенное влияние на урожайность зерна овса и гороха оказали повышенные нормы осадков городских сточных вод с цеолитсодержащей породой. Урожайность овса на их фоне возрастала на 43,5-44,2, урожайность гороха на 48,9-49,8. Сбор переваримого протеина в посевах овса на их фоне составлял 487,9-490,3 кг/га, содержание белка в зерне гороха увеличивалось на 2,3-2,7. Осадки городских сточных вод в чистом виде и в комплексе с цеолитсодержащей породой повышали концентрацию тяжелых металлов в зерне овса и гороха. Однако, концентрация тяжелых металлов была существенно ниже ПДК. Цеолитсодержащая порода снижала поступление тяжелых металлов в товарную часть растениеводческой продукции.In conditions of a low level of use of mineral fertilizers in agriculture due to their high cost and the almost complete absence of organic fertilizers, the development and implementation of technological methods for using alternative sources of organic matter and nutrients in agricultural practice is an important area of modern farming.The objective of the research was to study the aftereffect of reclamation norms of sewage sludge in the city of Penza and their combinations with zeolite-containing rocks on the yield and quality of crop products. The studies were conducted in the first agricultural-soil region of the Penza region in grain-crop rotation in the period from 2014 to 2019. It was established that the most significant effect on the grain yield of oats and peas was exerted by increased sediments rates of urban wastewater with zeolite-containing rock. The yield of oats against their background increased by 43.5-44.2, the productivity of peas - by 48.9-49.8. The collection of digestible protein in oat crops against their background was 487.9-490.3 kg/ha, the protein content in pea grain increased by 2.3-2.7. Sediments of urban wastewater in its pure form and in combination with zeolite-containing rock increased the concentration of heavy metals in the grain of oats and peas. However, the concentration of heavy metals was significantly lower than the maximum permissible concentration. The zeolite-containing rock reduced the influx of heavy metals into the marketable part of crop production.

Эффективность выращивания сахарной свеклы зависит от многих факторов, таких как погодные условия, соблюдение технологии, наличие современной техники, своевременное внесение удобрений и качество используемых семян. В настоящее время до 95 семян сахарной свеклы импортируются из-за границы. Модернизация производства, разработка необходимой семеноводческой сельскохозяйственной техники приобретает актуальное значение. Задача обеспечения полностью автоматизированной технологической цепочки от выборки маточников сахарной свеклы из бункера до их посадки в современных посадочных машинах на данный момент полностью не решена. В статье рассмотрены теоретические исследования геометрических и кинематических параметров вальцов, имеющих винтовую навивку с переменным шагом при транспортировании маточников сахарной свеклы к высаживающему аппарату. Полученные результаты проведенных исследований позволяют обосновывать геометрические и кинематические параметры вальцового транспортирующего устройства при заданной норме посадки маточников сахарной свеклы и, тем самым, полностью механизировать процесс посадки маточников сахарной свеклы.The effectiveness of growing sugar beet depends on many factors, such as weather conditions, technology compliance, the availability of modern machinery, timely fertilization and the quality of the seeds used. Currently, up to 95 of sugar beet seeds are imported from abroad. The modernization of production, the development of the necessary seed-growing agricultural machinery is becoming of current importance. The task of providing a fully automated technological chain from the selection of sugar beet mother root crops from the hopper to their planting in modern planting machines has not yet been completely solved. The article considers theoretical studies of the geometric and kinematic parameters of rollers having screw winding with variable pitch during transportation of sugar beet mother root crops to the planting unit. The obtained results allow to justify the geometric and kinematic parameters of the roller transporting device for a given planting rate of sugar beet mother root crops and, thereby, fully mechanize the process of their planting.

Root (wilt) disease is a very serious disease of coconut in eight southern districts of Kerala, India. A comprehensive breeding programme – the only practical solution for the management of the disease – was started at Central Plantation Crops Research Institute (CPCRI), Kayangulam during 1987. Coconut seedlings, belonging to five cross combinations with WCT viz. WCT (Inter se), West Coast Tall (WCT) (Self), WCT (Mixed Pollen), Chowghat Green Dwarf (CGD) x WCT and WCT (Open Pollinated) were studied for their incidence of root (wilt) disease. All the seedlings were planted during 1992 except CGD x WCT which was planted during 1991. In the absence of a mass screening technique under artificial conditions, assessment of resistance was based on natural infection. The progenies belonging to various cross combinations of WCT x WCT showed significant variability for incidence of root (wilt) disease. Observations, recorded during September 2002, revealed that the incidence of root (wilt) varied from 53.4 to 55.2 % in WCT x WCT crosses whereas CGD x WCT had 64.5 %. Open pollinated seedlings from healthy mother palms contracted 70 % incidence of the disease. The studies showed superiority of artificially pollinated seedlings (full sibs) over the open pollinated seedlings (half sibs) with regard to their susceptibility to the disease.

A field experiment on drip irrigation for Chowghat Orange Dwarf X West Coast Tall (COD X WCT) coconut hybrid was conducted in laterite soil at Central Plantation Crops Research Institute, Kasaragod (Kerala, India) to study the drip irrigation requirement and its influence on growth and yield. The treatments included were three levels of drip irrigation (at 33, 66 and 100% E0 daily), basin irrigation (100% E0) and rainfed control. The experimental results revealed that annual leaf production and leaf nutrient status of coconut palm was significantly higher in the irrigated treatments compared to the rainfed control. The female flower production and nut yield with 66 per cent of Eo was on par with 100 per cent of Eo through drip and 100 per cent of Eo through basin irrigation and significantly superior compared to drip irrigation at 33 per cent of E0 and rainfed control. Drip irrigation equal to 66 per cent of open pan evaporation (Eo) proved to be the economically efficient method of irrigation with water saving of 34 per cent compared to 100 per cent of Eo through basin and drip method.

In recent past the concept on the use of coconut oil (CNO) by the householders in Sri Lanka has been changing due to various reasons. The reasons were studied using the generalized linear models for the survey conducted during May/June 2001 for 366 householders representing three different population sectors (urban, rural and estate) and different income groups. The significant factors influencing the use of CNO are the type of oil used in past, monthly income, quality of CNO, misconception about CNO and the population sectors. The percentage of non-CNO users is considerably higher in the urban sector, whereas CNO still is the major edible oil in the rural and estate population sectors of Sri Lanka. The percentage of householders using CNO in the sample was 91.2. In 75% of the sample, the quantity of CNO consumption per person has reduced over the last five years. The main reason for dissatisfaction for CNO is adulteration. The proportion of CNO use was significantly higher in lower income groups than the higher income groups. The proportion of the CNO use decreased sharply when the income increases above Rs. 40,000 per month. The high-income earners have shifted their preferences towards other edible oil consumption. The findings of this study suggest that the growth of the per capita incomes and the rapid urbanization in the country further reduces the consumer demand for coconut oil, unless there are effective marketing strategies implemented to promote the CNO consumption in the long run. Both the proportion and rate of CNO use can be increased through an effective campaign via media. Improving the quality and dispelling the misconception among the householders would give better prospects to the coconut oil industry in Sri Lanka.

Root (wilt) disease is a serious malady in coconut causing a loss of approximately 968 million nuts a year in India. Integrated management practices are the only suggested methods to reduce its effect to some extent, while the development of resistant varieties will offer a permanent solution for which concrete breeding efforts are required. Considering the long life cycle of coconut, selection of resistant varieties through conventional methods will be time consuming and laborious. Molecular markers offer numerous advantages over markers traditionally used in plant mapping and selective breeding. Here, we present the optimization of PCR conditions for DNA amplification fingerprinting (DAF) of coconut using arbitrary oligonucleotide primers. Three of the primers could detect variations between root (wilt) resistant and susceptible coconut palms. This study constitutes the basis for future efforts to tag the root (wilt) resistant gene(s) in coconut.

In Sri Lanka, coconut is cultivated under diverse soil conditions of varying fertility status available in different agro-climatic zones. Although chemical and physical characteristics in some of these soils are known, their biological properties are yet to be studied. Hence the aim of this study was to determine the microbiological parameters in root zone of coconut grown in different soil series. For this study, 20 different soil series in coconut growing area were analyzed for number of total bacterial and fungal colonies, identification of bacteria and fungi, biomass C and N; CO2 evolution and nitrogen mineralization.

The microbiological parameters varied with the soil series. The bacterial population densities were significantly (p=0.001) high in Ambakelle, Kalpitiya, Rathupasa and Madampe soil series while the fungal colonies were significantly (p=0.001) high in Thambarawa, Pallama, Wilatawa and Ambakelle soil series.

Only Kalpitiya, Kuliyapitiya, Gambura soil series contained biomass C more than 200 mg/100 g of soils. Biomass N was the highest in Boralu soil series followed by Kalpitiya, Rathupasa and Gambura. Carbon diozide evolution was high in Kalpitiya, Katunayaka, Wariyapola soil series while N mineralization rate was high in Ambakelle, Weliketiya and Rathupasa soil series. Bacillus spp. were the dominant bacteria in all studied soil series. In addition, Micrococcus, Staphylococcus, Enterobacter, Serratia, Corynebacterium, Pseudomonas and Actinomycetes were also identified. Fungi such as Penicillium, Aspergillus and Curvularia were common in most of the soil series than other species.

Abstract
We present a catalog of high-precision proper motions in the Orion Nebula Cluster (ONC), based on Treasury Program observations with the Hubble Space Telescope’s (HST) ACS/WFC camera. Our catalog contains 2454 objects in the magnitude range of 14.2 < m
F775W < 24.7, thus probing the stellar masses of the ONC from ∼0.4 M
☉ down to ∼0.02 M
☉ over an area of ∼550 arcmin2. We provide a number of internal velocity dispersion estimates for the ONC that indicate a weak dependence on stellar location and mass. There is good agreement with the published velocity dispersion estimates, although nearly all of them (including ours at

and

mas yr−1) might be biased by the overlapping young stellar populations of Orion A. We identified four new ONC candidate runaways based on HST and the Gaia DR 2 data, all with masses less than ∼1 M
☉. The total census of known candidate runaway sources is 10—one of the largest samples ever found in any Milky Way open star cluster. Surprisingly, none of them have tangential velocities exceeding 20 km s−1. If most of them indeed originated in the ONC, it may compel the re-examination of dynamical processes in very young star clusters. It appears that the mass function of the ONC is not significantly affected by the lost runaways.
