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.","PeriodicalId":7924,"journal":{"name":"Agronomy research","volume":"18 1","pages":"2465-2477"},"PeriodicalIF":0.0,"publicationDate":"2020-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"66971184","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

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.","PeriodicalId":7924,"journal":{"name":"Agronomy research","volume":"18 1","pages":"603-618"},"PeriodicalIF":0.0,"publicationDate":"2020-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"66968719","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

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. There was a significant traffic intensity × stocking rate interaction, which influenced the depth and extent of soil compaction at depth. 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","PeriodicalId":7924,"journal":{"name":"Agronomy research","volume":"18 1","pages":"1163-1176"},"PeriodicalIF":0.0,"publicationDate":"2020-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"66969325","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

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.

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.","PeriodicalId":7924,"journal":{"name":"Agronomy research","volume":"18 1","pages":"404-409"},"PeriodicalIF":0.0,"publicationDate":"2020-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"66971446","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
