The aim of this work was to study the basic directions of scientific support introduction of organic farming in Ukraine. The study used methods of comparison, synthesis, analysis, induction and deduction. The article indicated on the main areas that need special attention from researchers and suggests one possible mechanism to remove the remaining obstacles to organizational issue introduction of scientific developments in the production of organic and training areas. This can speed up the creation of new and manage existing land ownership and land use organic farming with the introduction of advanced production technology of organic crop production.

AbstractClimate change and population increase are two challenges for crop production in the world. Hazelnut (Corylus avellana L.) is considered an important nut regarding its nutritional and economic values. As a fact, the application of supporting materials as foliage sprays on plants will decrease biotic and abiotic stresses. In this study, the effects of salicylic acid (0, 1 mM and 2.5 mM) and kaolin (0, 3% and 6%) sprays were investigated on morphological, physiological, pomological, and biochemical characteristics of hazelnut. The results showed that 1 mM salicylic acid and 6% kaolin had the best effects on nut and kernel weight compared to control. Biochemical parameters such as chlorophyll a, b, a + b, and carotenoid contents showed that salicylic acid and kaolin improved pigment concentration. Proline and antioxidant contents such as phenolic acids, SOD, APX, and CAT enzyme activities increased by these applications. On the other hand, lipid peroxidation, protein content, and H2O2 content were decreased. Based on the tolerance index result, Merveille de Bollwiller cultivar showed the highest tolerance while 'Fertile de Coutard' had the lowest value. Therefore, hazelnut performance may be improved through exogenous application of the signaling (salicylic acid) and particle film (Kaolin) compounds in warmer climates.

Abstract Weed-free irrigated trials were conducted in 2004 and 2005 to quantify phytotoxic effects of herbicides with the potential to be used in organic peanut production. Clove oil and citric plus acetic acid were each applied at vegetative emergence of peanut (VE), two weeks after VE (2 wk), four weeks after VE (4 wk), sequentially VE/2 wk, sequentially VE/4 wk, sequentially VE/2 wk/4 wk, and a nontreated control. Clove oil was more injurious (maximum of 28% visual injury) than citric plus acetic acid (maximum of 4% visual injury), with significant injury occurring with clove oil applied at 4-wk or sequentially. Citric plus acetic acid caused minimal peanut injury. There were no consistent effects of clove oil on peanut yield, although sequential applications of clove oil tended to reduce peanut yield. Peanut yield was not affected by citric plus acetic acid.

In this short article the author indicates the present stages of development of variety evaluation, testing, certification, production and marketing of quality seed—of cereals, industrial crops, pasture plants and vegetables—in major geographical regions of the world and draws attention to some of the underlying problems which must be faced in the future if further progress is to be made.

The aim of study was to investigate the influence of naturally occurring zeolite and diatomaceous earth, as inert dusts approved for insect pest control in certified organic crop production, on trading and breadmaking quality of treated wheat. The treatments significantly reduced the trading quality of wheat which was reflected through lowering of test weight. This effect was more marked in the case of low-vitreous wheat rather than in high-vitreous one. Investigation of rheological properties of flours made from the treated wheat demonstrated that treatments with natural zeolite and diatomaceous earth at all applied doses significantly increased the water absorption, which consequently increased the bread yield. However, these changes in the flour properties were not high enough to modify the quality attributes of bread as was shown by instrumentally measuring crumb hardness and springiness as well as sensory evaluation.

Проведено екотоксикологічну оцінку безпечностібіодобрива – продукту переробки гною у біогазовійустановці – за впливом на мікро- і мезофауну ґрунтута сільськогосподарські рослини. На основі отрима-них результатів було обґрунтовано екологобезпечнінорми застосування біодобрива в органічному вироб-ництві продукції рослинництва. Встановлено, щозастосування досліджуваного біодобрива позитивновпливає на урожайність сільськогосподарських куль-тур, а за умов дотримання екологобезпечних нормвнесення відсутній негативний вплив на агроеко-систему. An Eco toxicological assessment of the safety of biofertilizer was conducted – the influence of the product of the processing manure in biogas plant on the soil micro- and mesofauna and agricultural plants. Based on the results we have grounded the ecological safety rules of biofertilizers application in organic crop production. It was established that the use of studied biofertilizers affects positively the productivity of crops and if to subject to ecological safety standards of biofertilizers introduction there is no negative impact on agro-ecosystem.

From considerations of solar energy conversion data it is suggested that the total area required for feeding the entire human population of the world according to present agricultural practices and nutritional standards is relatively small, being about 2000 x 2000 km. This area includes roads etc. and that needed for crop production would be only 25% of this figure. The author proposes that agricultural production may benefit from the setting up, in various parts of the world, of 3000 units each about 30 x 40 km in area and devoted to a limited number of crops and served by its own research station. Some consequences of this suggestion are discussed.-F.A.S. (Abstract retrieved from CAB Abstracts by CABI’s permission)

AbstractIn much of the developing world, the high cost of purchased feeds makes meat and milk too expensive to be consumed by the producers' own families. A fish pond integrated with livestock or crop production provides an important source of animal protein for home consumption or sale. This protein involves almost no cash costs, since the needed nutrients and energy are supplied by crop residues, green manure, livestock manure and sunlight. Conversion of manure into animal flesh is possible because the anoxic sediments support a microbial flora similar to that of the rumen. Although integrated fish farming has been practiced for thousands of years in China, it has not yet been successfully adapted to all regions for which it potentially is applicable. A program in Wuxi, China brings together students and scientists from all over the world who are working towards that goal.

The article examines intensive and organic technologies for growing agricultural crops, their impact on the environment, human health, indicates what are the advantages and disadvantages of organic agriculture. It is noted that with intensive technologies for growing agricultural crops, their yield increases, but if the doses of chemicals are not observed, soil fertility is disturbed, the environment is polluted. Devoid of the disadvantages inherent in intensive technologies, organic farming is significantly inferior in productivity to it, due to which it is not able to reach the same production volumes, to ensure a comparable level of domestic consumption, which is demonstrated by traditional farming. The article compares the effectiveness of traditional and organic agronomic farming systems. It is shown that in the case of comparability of yield indicators, traditional technologies at lower selling prices are more effective in terms of profit and profitability indicators. The reasons for the slow development of the organic segment in the agricultural production of Russia are revealed. In this regard, the topic of support for foreign and Russian agricultural producers, including organic products, as well as the underdevelopment of its domestic market is touched upon. It is noted that, in contrast to developed countries, Russia’s share in the world market for organic products is insignificant. Therefore, it is too early to talk about the prospects for the development of organic agriculture in Russia. In the world, organic farming is stimulated, it occupies its own niche, but in all respects it lags far behind the traditional method of growing agricultural products. Its share in the world food market ranges from 2.6 to 3%.
