Limitation of water resources and its great impact on agricultural and natural resources play a crucial role in the efficiency of water use. Applying super absorbent polymer to the soil may be one of the methods to minimize the stress of weather dryness in arid and semi-arid regions. In order to evaluate the effects of hydrophilic polymer application on yield and water use efficiency of rapeseed plants, an experiment was conducted under field condition in 2012 at the Research Farm of the Faculty of Agriculture, University of Maragheh. Treatments’ factors were: (i) 3 super absorbent polymers (SAP) (Taravat A200) levels of 0 (without application), 75 and 150 kg ha-1 A200 application, (ii) three irrigation levels of 80, 120 and 180 mm evaporation from class A basin in main plots, (iii) two cultivars ʻHyola 401ʼ and ʻRVSʼ in sub plots as factorial split plot combination based on completely randomized block design with three replications. The results showed that in all of the measured traits within the experiment there were significant differences between SAP levels. Furthermore, increasing irrigation interval led to an increase in a thousand seeds’ weight, but decreased seed yield. Increasing water stress raised seed oil percent and infertile silique and subsequently resulted in reduced oil yield. ʻHyola 401ʼ was more susceptible to embryo abortion compared with ʻRVSʼ. As a conclusion of the research, SAP (A200) application in quantities smaller than 75 kg ha-1 may be recommended for rapeseed production under field condition.

Rapeseed pests will result in a rapeseed production reduction. The accurate identification of rapeseed pests is the foundation for the optimal opportunity for treatment and the use of pesticide pertinently. Manual recognition is labour-intensive and strong subjective. This paper propsed a image recognition method of rapeseed pests based on the color characteristics. The GrabCut algorithm is adopted to segment the foreground from the image of the pets. The noise with small area is filtered out. The benchmark images is obtained from the minimum enclosing rectangle of the rapeseed pests. Two types of color feature description of pests is adopt, one is the three order color moments of the normalized H/S channel; the other is the cross matching index calculated by the reverse projection of the color histogram. A multi-dimensional vector, which is used to train the random forest classifier, is extracted from the color feature of the benchmark image. The recognition results can be obtained by inputing the color features of the image to be detected to the random forest classifier and training.The experiment showed that the proposed method may identify five kinds of rapeseed accurately such as erythema, cabbage caterpillar, colaphellus bowringii baly, flea beetle and aphid with the recognition rate of 96%.

Abstract Biofuels production has risen rapidly in the past decade. Growing tendency can be expected in the future if national governments will continue in achievement of higher share of ‘green energy’. Diversification and self-sufficiency in energy and environmental aspects should underpin national and international policy. Consumption of biofuels in the transport sector has been significantly increasing since 2000. Biofuels produced in the EU are mostly first-generation biofuels, mainly produced from agricultural raw materials. The aim of the article is utilization assessment of the main agriculture crop used in biofuels production in the EU, which is rapeseed. For achievement of the research objective have been used analysis methods, basic statistical indices, the share of rapeseed production used in industrial purposes estimation and self - sufficiency index. The results of the research confirm authors’ expectations concerning shifting of agricultural production primarily intended for food and feed production to industrial purposes due to continually growing demand for biofuels.

The sulphur fertilizing experiment was introduced in the cropping year of 2001/2002, with winter rapeseed. The experiment was performed on a farm in Magyarhomorog, Hajdú-Bihar County. By selecting the location for the experiment, we had to consider the effect of the hard winter that was very unfavourable for rapeseed production, as there was serious frost damage on the sown area previously used for the experiment. In the arable land experiment, results of three different doses of treatment were compared in two replicates, on meadow soil. FitoHorm 32 S solution was used as a sulphur fertilizer, in doses of 3, 6 and 10 l/ha. Evaluating the results, we tried to find a correlation between the amount of fertilizer and the amount of seed-crop or the oil content of the seed. The nitrogen and sulphur contents of the samples were determined using classical methods and an Elementar VarioMax analyser. By this way, it was possible to examine not only the role of Sulphur in rapeseed production, but also to compare and evaluate results obtained by Kjeldahl and the modern, environmentally-friendly combustion method.

Structure Of Production

Introduction. Oilseeds in the world occupy significant areas of production, their consumption is growing every year. The share of domestic oilseeds in total oilseeds production is significant, and domestic demand is stable with a tendency to increase. Therefore, the analysis of trends and vectors of development of the oilseeds market is a priority area of research of the modern agricultural market. Methods. Theoretical and methodological basis for the analysis of the oilseeds market, determining changes in the structure of production and export of oilseeds, factors influencing the further development of this market were scientific works of domestic and foreign scientists on the dynamics and development of the world market of oilseeds. In the course of research the following methods were used: system generalization, abstract-logical, analysis and synthesis, observation, comparison, graphic. Information base for analysis – production and economic indicators of gross production, exports, prices of sunflower, rapeseed, soybeans for 2014-2019. Results. The tendencies and changes of world and domestic production and export of sunflower, soybean, rape in the conditions of development of the agricultural markets during 2014-2019 are investigated. Changes of structure of production of oilseeds in the world and in Ukraine are revealed. Thus, there is a redistribution of the structure of world sunflower production between the leading countries, and world rapeseed production is declining. It is established that the share of Ukraine in the total structure of world production of oilseeds has increased: for sunflower from 26 to 28%, for rapeseed – from 3 to 4,8%, for soybeans – from 1,2 to 1,3%. Discussion. The analysis of the main trends that have formed in the world and domestic market of oilseeds, as well as the dynamics of changes in the structural ratios of production indicators of oilseeds provides an opportunity to assess and predict market conditions. Keywords: agricultural market, oilseeds, sunflower, soybean, rapeseed, gross harvest, export.
