Identification and in silico comparison of transposable elements of Solanum tuberosum subsp. andigena from two localities of Peru

The potato is one of the main crops in Peru, being one of the pillars in the country's economy. It also has a cultural importance, being a basic element of Peruvian gastronomy and an emblematic crop of the Peruvian highlands, where small farmers over time have been able to conserve and cultivate 6048 native varieties. In Peru, around 300,000 hectares of potatoes are planted annually, and in 2019 Peru remained the main potato producer in Latin America, registering an annual production of 5.3 million tons. Therefore, it is necessary to study and characterize the genome of this very important tuber for the country. Although there are many potato genomic studies in the world and in Peru; These have been based on the search for genes of importance, genetic diversity, etc. and little has been deeply studied about the transposable elements (ETs) that are part of its genome. It is known that in many eukaryotes, transposable elements are powerful drivers of genome evolution, and they occupy a considerable part in plant genomes, so with these studies, more could be understood about how these ETs have intervened in the evolution of the potato in Peru; thus, how these mechanisms would help in the future to the survival of the species in scenarios of climate change, among others. This study proposes the identification and comparison of the transposable elements of the only 2 complete genomes of potatoes grown in Peru, found in the NCBI database, one from the department of Puno and the other from Cuzco. There are various approaches to search for ETs in genomes, but for a complete and reliable annotation, it has been shown that the best strategy is the adoption of combined approaches, in this study, we will use 2 approaches, one based on homology, with the program RepeatMasker, and the other de novo, with the RepeatModeler2 program.

Strategic Planning for Green Logistics Implementation in Potato Agro-Industry

Indonesia is the largest potato producer in Southeast Asia. Annual production averaged 1.09 million tons. However, productivity is still low, ranging from 16.4 - 18.22 tons/ha. The objective of this study was to propose a strategic planning of the Green Logistic Distribution Center (GLDC) in the potato agro-industry using Interpretative Structure Modeling (ISM). A contribution of this research was that we used ISM to analyze the sustainability policy of the green logistics program which includes social, economic, and environmental issues. The result showed that the objectives such as availability of raw materials (1), supplier of potato (3), market place (5), traffic transportation (7), economic factor (8), and environmental issue (9) include variable linkages from the system. Every action on these objectives will result in a successful GLDC program, while the lack of attention to these objectives will lead to program failure. In this case, the driver power is large but has little dependence on the program. While the other sub-elements of purpose are categorized as dependent, this is interpreted more as a result of other objective actions. With two forms of information, ISM and DP-D matrix diagrams, the deepening of the GLDC program is made possible to support strategic planning.

AN ECONOMIC ANALYSIS OF PRODUCTION, MARKETING AND VALUE CHAIN OF POTATO IN BAMYAN PROVINCE

The present study on “An economic analysis of production, marketing and value chain of potato in Bamyan province” undertaken for studying the trend in production, productivity, marketing, value chain, cost of cultivation and problems faced by the farmers in production and marketing of potato. In Bamuan, potato is an important cash crop and source of income of agriculture production. Potato is emerged as an important vegetable crop for Yakowlang district of Bamyan province, with better productivity. Therefore, a study of economics of cultivation, marketing, value chain in Yakowlang district was undertaken. For this study, Yakowlang district and Bamyan center selected because of high level of production. In this study 126 farmers were selected from six villages, three for each district (Bamyan and Yakowlang). Relevant information was collected from the potato producer to know the economics of potato cultivation and analyzed according to various cost concept used in farm management studies. Cost of cultivation of potato calculated from the primary data collected from purposively selected grower of potato of Bamyan province. According to study, using gross margin analysis, net margin of farmers as average is around 134243 AFN per Hectare and according to production and yield of different potato varieties in Bamyan, Kabul and Panjsher provinces. Loura variety give highest yield in Bamyan province i.e. 65.37 Ton per Hectare and similarly in Kabul Amany Variety give highest yield that is 45.71 Ton per Hectare and finally Panjsher province is a major producer of potato in Afghanistan also Amany gives highest yield that is 51.67 Ton per Hectare. Similarly, marketable surplus of three different category of farmers, small farmers are around 88.4 percent, medium farmers were 92.68 percent and large farmers were around 90 percent had marketable surplus. Also major constraints with the farmers in potato production, and marketing ranked first was price instability, followed by high storage charges, uncertainty of water, inadequate marketing facility and spoilage of potato.

Farmers’ knowledge of sustainable potato cultivation techniques in Poland

The research was aimed at determining the farmers’ knowledge about sustainable agricultural techniques in potato cultivation by identifying their personal, social, economic and communication characteristics. In addition, the intention of research was to find a connection between the farmer's knowledge of potato cultivation in sustainable agricultural techniques and independent variables that characterize the farmers. These studies were based on primary data collected in the years 2014–2016 on a representative sample of 152 potato producers in the Mazovian province. A standardized structure questionnaire was used to collect the field data through personal interviews. The questionnaire consisted of two parts: the first part contained independent variables (age, level of education, marital status, occupation, sex, source of income), while the second one consisted of an assessment test of potato producer knowledge on sustainable agricultural techniques. The results showed that knowledge about potato cultivation for sustainable agricultural techniques is medium with a low tendency. Among the socio-economic variables, the level of education and occupation were the most important factors influencing the knowledge of a farmer-producer of potato with sustainable agricultural techniques in the studied area. The significant differences occurred between knowledge about potato cultivation for sustainable agricultural techniques according to variables in categories (age, level of education and profession). Only three independent variables had a significant link to the adoption of innovation in agriculture: source of income, level of education and occupation.

LESSONS FROM A COSTS ANALYSIS IN POTATO PRODUCTION

The potato is one of the most widely cultivated horticultural crops in the world. Brazil ranks 21st among the world's largest potato producers, and the United States (US) is the fifth largest producer in the world. This study analyzes and compares the economic, financial aspects of potato production in the Vargem Grande do Sul region, SP (Brazil), and southwestern Idaho (US), seeking to identify which aspects of American production can serve as reference for technical and financial improvement of the Brazilian production. Data from official sources were analyzed using principal components analysis (PCA). Potato producer in Vargem Grande do Sul need learning how to reduce the factors of production costs to have better financial results in your potato production.

Production of Bioethanol from Waste Potato

Using primary energy sources in World as fossil fuels, causes air pollution and climate change. Because of these reasons, people looking for renewable energy suppliers which has less carbondioxide and less pollution. Carbon in biofuels is producing from photosynthesis. For this, burning biofuels don’t increase carbondioxide in atmosphere. Scientists predict that plants with high carbonhydrate and protein contents are 21. centuries biofuels. Potatoes are producing over 280 million in whole world and Turkey is 6th potato producer. Turkey produces 5250000 tonne of potatoes. Approximately 20% of potatoes are waste in Niğde. Our study aimed to produce bioethanol from Solanum tuberosum by using the yeast Saccharomyces cerevisiae. As a result renewable energy sources can be produced from natural wastes.
