By-catch fish is caught unintentionally during the fishing and is currently thrown back in water bodies to cause the water pollution. Currently fishermen does not have a motivation to bring the by-catch fish to the shore, as it needs to be sorted by fish species, causing fishermen extra work without additional income. Estonian Ministry of Rural Affairs decided to give funding to present study with purpose to find solution to this matter. One possible solution for by-catch fish utilization is to produce high value nutrient rich fertilizer in order to close nutrient cycle and return valuable nutrients into soil. The adaptive study of outdoor windrow composting was conducted with consecutive treatments, rather than simultaneously, in order to make adaptive improvements to the set-up of each consecutive treatment. The consecutive treatments showed that fish waste composting is manageable from a technical perspective, feasible in a temperate climate, and that this type of compost holds high potential as an organic fertiliser or soil improver. Composting process started rapidly and, as required by the EU Commission regulation EU 142/2011, temperatures exceeded 70 h in all windrows. While initial treatments suffered from odours, as well as events inhibitive to the composting process, these disadvantages were successfully avoided in later treatments by adding a biofilter and inoculant from previous composting windrows, as well as lake sediments. Rather than disposing of low-value fish, these can be recycled into stable and nutrient-rich compost on-site, near fishing harbours.

Increasing chicken meat production needs an alternative and easily available protein source as a potentional substitute for soybean meal or fishmeal. The insect meals seem to be the most appropriate alternative. Of all insect species, Tenebrio molitor, Hermetia illucens and Musca domestica are the most suitable species for commercial exploitation in poultry feed. On the basis of numerous studies, insect meals contain sufficient nutrients (high quality protein and fat) for broiler production. Potential of insect meals used for feed of chickens is discussed based on published data. Many reviews summarizing the latest insights about the insect meals as an alternative protein source in poultry have been written. However, the present work describes not only the insect production, nutritional value and digestibility of the insect meals, but mainly the effect on performance, carcass characteristics and meat quality of chickens fed insect meals, which has not been in any review summarized yet. The study describes also the risks and safety of the insect meals. Based on numerous studies, insect meals can have a positive influence on growth without negative impact on carcass and meat quality characteristics.

Large-scale cultivation of contamination free plants requires a good standardization protocol and production methods. Basil is widely used for cosmetics, food and pharmaceutical industries as it is rich in many bioactive compounds. This present study aimed to evaluate the growth and in vitro anatomical aspects of apical buds of basil grown under different concentrations rowth regulators like: NAA (Naphthalenoacetic Acid), BAP (6-benzylaminopurine), and KIN (Kinetin). The in vitro establishment was evaluated every 20 days to calculate the, the percentage of plants with calluses, appearance of the roots, any abnormal seedlings, any oxidized seedlings, and the number of sprouts per plant. Growth, physiological, and morpho-anatomical evaluations were performed at 80 days. Basal callogenesis was observed when cytokinin’s and auxins are used in combination. Auxin treatments caused hyperhydricity in the stems and leaves. Medium A2 (0.05 mg L of NAA and 0.1 mg L of BAP), and A3 (0.05 mg L of NAA and 0.1 mg L of KIN) resulted in the best development of basil plants, cultivar ‘Alfavaca Green’. The A2 produced plants with greater numbers of leaves, an average bud length of 59.81 mm, and the best root properties. A2 and A1 have a higher percentage of hyperhydricity (83 and 67%). The A3 resulted in an acceptable number of leaves (range: 21–39), and this treatment produced the best shoot properties as well as fewer plants with hyperhydricity. In addition, the A3 treatment produced plants with a shoot length, high shoot fresh and dry mass (2.82 and 0.23 g), high chlorophyll index and leaf anatomy that was similar to the control. Excluding the control, the other treatments presented more than 90% of the explants with calluses in their bases.
无公害植物的大规模种植需要良好的标准化方案和生产方法。罗勒富含多种生物活性化合物，被广泛用于化妆品、食品和制药行业。本研究旨在研究罗勒在NAA(萘乙酸)、BAP(6-苄基氨基嘌呤)和KIN (Kinetin)等不同浓度生长调节剂条件下根尖芽的生长和体外解剖学特征。每隔20天进行一次离体培养，计算愈伤组织百分率、根系外观、异常苗、氧化苗及单株芽数。在第80天进行生长、生理和形态解剖评估。当细胞分裂素和生长素联合使用时，观察到基部的胼胝质形成。生长素处理导致茎叶过度缺水。培养基A2 (0.05 mg L NAA和0.1 mg L BAP)和培养基A3 (0.05 mg L NAA和0.1 mg L KIN)处理的罗勒植株发育最佳，品种为Alfavaca Green。A2品种叶片数量最多，平均芽长59.81 mm，根系性状最好。A2和A1的高水饱和度更高(分别为83%和67%)。A3处理产生了可接受的叶片数量(范围:21-39)，并且该处理产生了最好的茎部特性，并且产生了较少的高水分植株。此外，A3处理植株的茎长、鲜干质量(2.82 g和0.23 g)、叶绿素指数和叶片解剖结构与对照相似。除对照外，其余处理均有90%以上的外植体基部有愈伤组织。

Soil compaction has detrimental effects on the physical, mechanical and hydraulic properties of soils, and affects important soil processes and function, and crop productivity. This work was conducted to investigate soil compaction impacts in integrated arable croppinglivestock systems managed under conventional tillage (CT) and no-tillage (NT). The work examined the combined effects of cattle trampling and farm machinery traffic on: soil strength, soil deformation, and water infiltration into soil. The following treatments were applied to soil (Entic Haplustoll, 60% sand) managed under CT and NT: three traffic intensities (1, 5, 7 passes) performed with light (2WD, 53 kN) and heavy (4WD, 100.4 kN) tractors, and two stocking densities (400 and 700 kg ha), respectively. Controls were also used to represent the condition of the soil without any effect of livestock or field traffic. In both tillage systems, soil penetration resistance (strength) increased and water infiltration into soil decreased as traffic intensities or stocking rates applied increased.

Despite these results, stubble grazing during fallow should not be discouraged as this practice offers mixed farming systems several agronomic and financial benefits. If stubble was to be grazed, the system would need to be carefully managed: (1) avoid ‘random’ traffic using permanent or semipermanent traffic paths to minimise the field wheeled area, (2) vacate livestock from the field, or confine it to a sacrificial area, when the soil water content exceeds a critical level above which
土壤压实对土壤的物理、机械和水力特性产生不利影响，影响重要的土壤过程和功能，影响作物生产力。本研究旨在探讨传统耕作(CT)和免耕(NT)对农牧结合系统土壤压实的影响。研究了牛践踏和农机交通对土壤强度、土壤变形和水分入渗的综合影响。对CT和NT管理下的土壤(纯Haplustoll, 60%砂)进行以下处理:分别使用轻型(2WD, 53 kN)和重型(4WD, 100.4 kN)拖拉机和两种放养密度(400和700 kg ha)进行三种交通强度(1、5和7次)。对照也被用来表示没有牲畜或田野交通影响的土壤状况。在两种耕作制度下，随着交通强度或载畜率的增加，土壤渗透阻力(强度)增加，土壤水分入渗减少。交通强度与载畜率之间存在显著的交互作用，这种交互作用影响了深层土壤压实的深度和程度。尽管有这些结果，休耕期间的留茬放牧不应受到阻碍，因为这种做法为混合耕作系统提供了几种农艺和经济效益。如果要放牧残茬，则需要仔细管理该系统:(1)避免使用永久性或半永久性交通路径的“随机”交通，以最大限度地减少田间轮式面积;(2)当土壤含水量超过临界水平时，将牲畜从田间腾出，或将其限制在牺牲区域

Results of the research were based on a field experiment carried out in 2007–2009 at the Experimental Plant of the IHAR-PIB in Jadwisin, on podzolic soil with a granulometric composition of loamy sand. The experiment was established by means of a random sub-block method in a dependent split-plot pattern, in triplicate. The first order factor were the potato cultivars: ‘Irga’ and ‘Fianna’, the second order factor were the methods of weeds regulation: 1) control − without chemical protection; 2) extensive mechanical treatments (every 2 weeks) from planting to closing the rows; 3) Sencor 70 WG – 1 kg ha before potato emergence; 4) Sencor 70 WG – 1 kg ha + Titus 25 WG – 40 g ha + Trend 90 EC – 0.1% before potato emergence; 5) Sencor 70 WG – 0.5 kg ha after potato emergence; 6) Sencor 70 WG – 0.3 kg ha + Titus 25 WG – 30 g ha + Trend 90 EC – 0.1% after potato emergence; 7) Sencor 70 WG – 0.3 kg ha + Fusilade Forte 150 EC – 2 dm ha after potato emergence; 8) Sencor 70 WG – 0.3 kg ha + Apyros 75 WG 26.5 g ha + Atpolan 80 SC – 1 dm ha after potato emergence. The number, floristic compositions, fresh weight and dry matter of weeds were determined. A high, yield-protective effect of herbicides was obtained as a result of limited competition of weeds. Mechanical care contributed to the increase in the total potato yield by 36.2%, and the marketable yield by 45.7%, as compared to the control object.

The present research was carried out with the aim to determine the correlation between ploidy level, steroid glycoalkaloids (SGAs) content and resistance against Late blight (Phytophthora infestans (Mont.) de Bary), and Colorado potato beetle (Leptinotarsa decemlineata (Say)) in cultivated and wild Solanum species preserved in the Potato Gene Bank of Czech Republic. In this study 27 species were included which consist of five cultivated and 22 wild species, with a total of 31 genotypes (four species represented by two accessions). In this study 70.97% of genotypes were evaluated as diploid, 3.23% were triploid, 19.35% tetraploid and 6.45% hexaploid as depicted from counting of chromosomes. The highest concentration, of foliage α-solanine (5,450 mg kg) and α-chaconine (9,420 mg kg) of dry matter was found in the specie S. yungasense 00070, whereas lowest 1.1 mg kg and 2.3 mg kg in S. pinnatisectum 00051, respectively, Tukey’s test of one way anova was performed for getting significance from the data obtained and found significant variation among species of steroid glycoalkaloids (SGA) content in dry weight at level of P ≤ 0.01. Leaf damages by Leptinotarsa decemlineata under field experiment circumstances were also recorded. In vitro study, S. bulbocastanum PIS 06-17 and S. bulbocastanum 00240 shown resistant to P. infestans upon inoculation of aggressive isolates and strong resistance was observed in S. stoloniferum 00295, S. sucrense 0062 and S. yungasense 0070. Nevertheless, there was no correlation of ploidy level, SGA contents and resistance to the CPB (r = 0.00) and late blight (r = 0.076) found in the investigated Solanum species.

This article describes using renewable energy for bioethanol production. Kostanay Region is a developed agricultural region. Most part of its area is under grain crops and corn, oil crops and vegetables. In the course of production, transportation, storage and processing of agricultural crops, a large part of them becomes unsuitable for use; in future they cannot be used for the intended purpose. Substandard product often stays in the fields to rot or is thrown away. Information considered in this article demonstrates that agricultural waste can be used to produce rather inexpensive bioethanol. Most part of the population in this region is rural. Settlements are far apart from each. It would be reasonable to use bioethanol as a source of electric and thermal energy to meet the needs of rural residents and infrastructure. Wastes from bioethanol production can be used for feeding animal stock what is also important for rural areas and reduces environmental burden. In the course of human life, solid waste is formed that is suitable for producing bioethanol, and consequently, for generating thermal and electric energy. Presented calculations show the feasibility of processing municipal solid waste into bioethanol. EU countries successfully use researches performed by their scientists for developing technologies for the production of bioethanol and synthetic fuels. Kazakhstan, with its experience in cultivation of oilseeds and required planted area, can successfully develop bioethanol industry. No researches in this respect have been conducted to this day in Kazakhstan. Using bioethanol provides consumers with their own energy sources that meet quality standards, thereby increasing energy security of region, reducing the amount of harmful emissions into the atmosphere, and creating small-scale energy enterprises where rural residents can work.
