Characteristics of Work Accident to Tobacco Farmers in Indonesia

Tobacco farmers are individuals who are members of farming groups engaged in the cultivation of the agricultural sector in the form of tobacco. When carrying out tobacco cultivation activities, farmers are vulnerable to work accidents. The purpose of this research was to describe the characteristics of work accidents on tobacco farmers in Kalisat District, Jember Regency. The research design used descriptive quantitative. This research employed a purposive sampling technique, with a total of 97 tobacco farmers as respondents. The research data were collected through a demographic questionnaire and a work accident accident questionnaire. In the type indicator, it was found that 43.3% farmers often experienced incidents of being hit by immovable objects. In the object indicator, 36.1% farmers often experience accidents due to work equipment. In the indicator of the nature of the wound 26.8% farmers often experienced minor injuries and 9.3% stated that they always experienced these incidents. In the indicator of the location of the wound, farmers often experienced injuries on the hands, namely 36.1%. In the cause indicator, 66.0% farmers stated that they rarely use Personal Protective Equipment (PPE).

Colonzation of Tobacco Plants by Fungal Entomopathogens and the Effect on Consumption over Diabrotica speciosa (Coleoptera: Chrysomelidae)

Entomopathogenic fungi are naturally occurring microorganisms that attack insect pests, making them exceptional allies when developing biocontrol strategies. A particular aspect of the ecology of these fungi is that they interact not only with insects but also with plants, being able to colonize them endophytically without causing symptoms of disease. The objectives of this study were to determine the endophytic capacity of different species of entomopathogenic fungi in tobacco plants by means of foliar spraying, to evaluate the persistence in planta of the entomopathogens and the effect of endophytes on consumption by coleopteran pests. A total of 24 strains were analyzed to test endophytic capacity at 7, 14, 21 and 28 days post inoculation. A significant effect of the strains was found. On days 7, 14 and 21, the strain that showed the highest colonization percentages was B. bassiana LPSc 1215, and at day 28 B. bassiana strains LPSc 1215 and LPSc 1212 exhibited the best endophytic capacity, maintaining elevated colonization percentages. Choice test results indicated that D. speciosa fed indiscriminately on colonized and non-colonized leaves. The results indicate that B. bassiana LPSc 1215 constitutes a strain that would merit further investigation for the purpose of pest management in tobacco cultivation.

Performance and Control of Tobacco in Chinese Film and Television Dramas

Objectives: China is the world's largest country in tobacco cultivation, production, consumption and smokers. The number of smokers accounts for nearly 30% of the total number of smokers in the world. 740 million people are endangered by "second hand smoke", most of them women and children. To ac hieve the goal of healthy China, tobacco control is a very important link. Reducing the number of smokers is an important problem to be solved, and the mass media plays an important role in this problem. Once tobacco is shaped as a positive symbol in mass communication, smoking will become an unhealthy social atmosphere. Then, what kind of image tobacco generally appears in the mass media and what impact it will bring to the society, this paper attempts to explore the tobacco symbols in Chinese film and tel evision dramas as the research object.

Changes in the genetic composition of Myzus persicae nicotianae populations in Chile and frequency of insecticide resistance mutations

Myzus persicae is a cosmopolitan aphid that is highly polyphagous and an important agricultural pest. The subspecies M. persicae nicotianae has been described for highly specialized phenotypes adapted to tobacco (Nicotiana tabacum). In Chile, the population of M. persicae nicotianae was originally composed of a single red genotype that did not possess insecticide resistance mutations. However, in the last decade, variation in the colour of tobacco aphids has been observed in the field. To determine whether this variation stems from the presence of new genotypes, sampling was carried out across the entire distribution of tobacco cultivation regions in Chile. The aphids collected were genotyped, and the frequency of kdr (L1014F), super-kdr (M918T), modification of acetylcholinesterase (MACE) and nicotinic acetylcholine receptor β subunit (nAChRβ) mutations associated with insecticide resistance was determined. A total of 16 new genotypes of M. persicae nicotianae were detected in Chile: four of them possessed the MACE mutation, and none of them possessed the kdr, super-kdr or nAChRβ mutation. The previously described red genotype was not detected in any of the sampled fields over two seasons. These results raise questions about the mechanisms underlying changes in the genetic structure of M. persicae nicotianae populations in Chile. Future research aimed at addressing these questions could provide new insight into aphid evolution and agricultural practices.

Japan’s Rare Earth Strategy and Price Volatility on Tobacco Cultivation: How Demand Management Worked?

The two major light rare earth elements (REES) involved in Japan’s rare earth strategy: Cerium Oxide and Praseodymium Oxide, whether the price is affected by the demand management capability of the Japanese tobacco cultivation industry is the problems to be solved in this paper. For this aim, the monthly data from April 2008 to June 2017 was used to construct a model which takes into account the financial factors and demand factors for the two product by nonlinear methods, and use MSVAR model with regime-switching characteristic. The results are as follows. In general, different products have different price volatility characteristics. Even if the number of the regime is the same, the volatility connotation is different. Firstly, Cerium Oxide in the violent fluctuation regime has financial properties, and the financial properties of Praseodymium Oxide are reflected in three regime stages. Secondly, Japan’s industry factors have a significant change in the relationship between Cerium Oxide and Praseodymium Oxide to a certain extent. Among them, Information technology and tobacco cultivation Industrials as direct influencing factors have a counter-regulatory effect on the two product at certain price fluctuations, which reflects the direct demand management capabilities of Japanese companies, and Utilities and Telecommunication have a counter-regulation effect on Cerium Oxide and Praseodymium Oxide at certain price fluctuations, which reflects the indirect demand management ability of Japanese companies.

Behavior of Smallholder to Improve Individual Breeding Environment and Tobacco Growing Environment-A Case Study of 184 Waterfowl Farmers and Tobacco Farmers in Jiangxi Province

Under the background of the structural reform on the agricultural supply side and the tightening of environmental protection policies, China’s agricultural industry is facing prominent problems such as low scale, poor mechanization level and serious ecological environment pollution, especially the scattered breeding behavior of small farmers in waterfowl breeding industry and in tobacco growing industry, which has a serious impact on the surrounding ecological environment. In this paper, based on the survey data of 184 waterfowl farmers and tobacco farmers in Jiangxi province and from the perspective of small farmers of waterfowl breeding and tobacco growing, the factors influencing small farmers’ behavior of improving their individual breeding environment and carrying out green ecological behavior are analyzed by using binary logistic regression model. It is concluded that the gender and age of farmers have a negative impact, while farmers’ education level, farmers’ concurrent employment, breeding technology training and government support have a significant positive impact on small farmers’ behavior of improving their individual breeding and planting environment. Finally, some suggestions are put forward, such as optimizing the production layout of waterfowl industry, improve green tobacco cultivation, constructing green ecological development system of waterfowl industry, popularizing green ecological breeding mode and strengthening policy support and supervision, with a view to improve the present situation of poor breeding environment and serious pollution of small farmers in China, promote the development and transformation of waterfowl industry and tobacco industry in China, and promote the sustainable development of ecological environment and ecological economy of waterfowl industry and tobacco industry in China.

EVALUATING ENERGY CONSUMPTION EFFICIENCY IN TOBACCO PRODUCTION: APPLYING DATA ENVELOPMENT ANALYSIS

Tobacco is considered as one of the most important industrial cash crop and source of livelihood to many families in Pakistan. Considering the contraction of land under tobacco cultivation, the present study is intended to evaluate the production efficiency of tobacco growers in southern Punjab, Pakistan. The Data Envelopment Analysis model was used to investigate energy usage efficiency of tobacco farmers based on seven energy inputs; human labour, farm machinery, irrigation, diesel, fertilizers, chemicals, seeds, and a single output. Moreover, the current study also used DEA – super efficiency to identify and rank efficient and inefficient tobacco producers; and to suggest optimum energy requirements and energy savings potentials. The primary data from 210 tobacco growers were collected in-person interviews by random sampling technique. The findings of the study revealed that average energy consumed in the form of inputs and yield obtained in tobacco production was 52,703.58 MJ/ha-1 and 3,096.98 MJ/ha-1, respectively. Average technical, pure technical, and scale efficiency score was calculated to be 0.902, 0.961, and 0.938, respectively. Likewise, the energy-saving ratio in tobacco production was estimated to be 13.83%, which implies that by adopting the proposed recommendations about 7,121.66 MJ/ha-1 energy could be saved without compromising the output. Also, fertilizers, chemicals, irrigation, and diesel had the highest share in the consumption of energy inputs. The findings of the study provides pinpoint options to the agricultural polices makers to launch the technical training programs for the tobacco farmers to adopt better management practices to optimize the application of energy inputs to reduce the cost of tobacco production. The agricultural extension department should also visit the tobacco fields to assist the farmers about timely application of inputs and with extension services.

RNA-Seq, physiological, and biochemical analysis of burley tobacco response to nitrogen deficiency

To explore the effects of nitrogen deficiency in burley tobacco, two varieties were cultivated and subjected to conditions of sufficient and deficient nitrogen. The natural characteristics of varieties TN90 and TN86 during tobacco cultivation were similar for nitrogen metabolism. Both carbon and nitrogen metabolism were significantly affected by reducing amounts of applied nitrogen. Under nitrogen-deficient conditions, average leaf biomass, root weight, photosynthetic rate (Pn), pigment levels, total nitrogen, and nitrate content of TN86 and TN90 were significantly decreased by 52.88%, 69.19%, 22.65%, 46.80%, 37.42%, and 79.15%, respectively (p < 0.01). Nicotine and soluble reducing sugar contents were significantly decreased by 96.67% and 95.12%, respectively, in TN86 roots (p < 0.01), which was consistent with the reductions in root surf area, average diameter, and root volume. Nitrogen deficiency induced 6318 differentially expressed genes in both TN90 and TN86, which were highly expressed. In total, 428 upregulated genes were analysed and found to be mainly enriched in the MAPK signalling pathway, sesquiterpenoid and triterpenoid biosynthesis, and arginine and proline metabolism. Meanwhile, 213 downregulated genes were analysed and found to be mainly enriched in photosynthesis, nitrogen metabolism, and amino acid biosynthesis. Reduced pigment content and Pn may result in low carbohydrate formation and decreased leaf biomass in burley tobacco under nitrogen-deficient conditions.

Environmental Degradation due to Tobacco Cultivation in Northern Bangladesh

A field study was conducted in Northern Bangladesh, Rangpur district to observe the impact of tobacco cultivation on the environment as well as to characterize contributing factors motivating tobacco cultivation. Information was collected from the tobacco cultivators by a questionnaire survey that was conducted in four mostly tobacco cultivated upazilas, namely Badargonj, Taragonj, Rangpur Sadar, Gangachara of Rangpur district. Information from non-tobacco cultivators was also collected from Mithapukur Upazila. Survey findings revealed that 62.16% of respondents believed that soil productivity is decreasing in the tobacco field and 70.27% of tobacco farmers were using more chemical fertilizer per year than the previous years. More than half (54.05%) of respondents reported that tobacco is replacing native food crops. Moreover, 51.30% of tobacco farmers were facing various health hazards due to tobacco cultivation. The present study also investigated that 97.14% of farmers got a high benefit along with 89.19% of respondent’s availed organizational support from tobacco marketing companies. The overall satisfaction rate with the price was 80.56%, which was the main contributory factor for tobacco cultivation in the study area. The survey results also identified that farmers from Mithapukur Upazila gave up tobacco cultivation due to health hazards and unnecessarily underestimating the grade of tobacco leaf by the buyer company.
