Button Mushrooms

The study was conducted to analyze the comparative economics of oyster (Pleurotus ostreatus P.) and button mushrooms (Agaricus bisporus J.) in Kathmandu district of Nepal during the year 2012 with the objective to compare their resource productivity. Primary data were collected from semi-structured pretested questionnaire from purposively selected 45 growers from each category. The examination of resource use efficiency showed that most of the resources were not used efficiently and there is further scope of commercialization. It is imperative to banks for investment in mushroom. Study revealed materials are to be decreased in case of oyster mushroom and labor use is to be increased in button mushroom. It is suggested to cultivate button mushroom instead of oyster as button mushroom has increasing return to scale. It was concluded that the mushroom farming was highly profitable and suggested to cultivate button mushroom in long run and oyster mushroom in short run.

Mushroom Species

Mushroom cultivation in South Korea is increasing fast last decades. Mushroom cultivation of South Korea is 173577 tones and South Korea gains 800 million dollars income annually. Different kind of mushroom species are cultivated and 31% enoki mushroom (Flammulina velutipes), 26% king oyster (Pleurotus eryngii), 26% oyster mushroom (Pleurotus ostreatus), 13% white buton mushroom (Agaricus bisporus) and 4% rest of the total mushroom Lentinula edodes, Ganoderma lucidum, Phellinus vb. are produced in Korea. 764 ha mushroom growing area was used for mushroom cultivation. 31% of total growing area is oyster mushroom (Pleurotus ostreatus) and 14% king oyster (Pleurotus eryngii), 6% winter mushroom (Flummulina velutipes), 16% white button mushroom (Agaricus bisporus), 3% Phellinus, 3% reishii (Ganoderma lucidum) and 27% other mushrooms. Mushroom is consumed frequently in Korea and mushroom consumption per person is 4.2 kg. Growing on log culture (oak mushroom, reishi and Phellinus), growing on shelves (Agaricus bisporus and Pleurotus ostreatus) and bottle culture (Flummulina velutipes, Pleurotus ostreatus, Pleurotus eryngii) are commonly used growing systems.

Abstract Button mushroom (Agaricus bisporus) is sold well for its unique flavour and nutritional benefits. However, the mushroom flavour deteriorates quickly during storage because of its delicate structure and high moisture. In this study, the effects of nitric oxide (NO) application on flavour compounds and antioxidant enzyme activities of stored button mushrooms were investigated. The button mushrooms were immersed in the NO donor sodium nitroprusside (15 μmol/L) for 3 min and then stored under the condition of 4 °C, 90% relative humidity for 12 days. Results showed that the treated mushrooms have reduced weight loss rate, uniform white colour, and higher firmness during storage. Compared to the control, the ketones, alcohols, esters, and aldehydes in the NO-treated button mushroom increased sharply at 3 days of storage and then showed a continuing decline trend, except ester compounds which reached the peak value at 6 days of storage. In addition, NO treatment increased the total phenolics and catalase activity and inhibited the polyphenol oxidase activity in the stored button mushroom. These results indicated that NO treatment is an alternative storage technology to enhance antioxidant capacity and maintain flavour and consumer acceptance of stored button mushroom.

Descriptive Approach

This study aims to determine the factors of production that affect oyster mushroom farming and analyze the level of efficiency of the use of production factors on oyster mushroom farming in UPT Agriculture Area Sukaraja. The method used in this research is survey with explorative descriptive approach. The data used are primary data secondary data obtained through interviews, questionnaires and literature study. The results analsis show a total coefficient value of 2.143. This value indicates the scale of oyster mushroom production is in phase I or increasing return to scale (IRS). The value of the coefficient of determination (R2) is 92.3 percent means that 92.3 percent of oyster mushroom production can be explained by variable use of production factors, while the remaining 7.7 percent is influenced by other variables besides the use of production factors not included in the model. The use of production factors that significantly influence the variation of oyster mushroom production are land and sawdust. While seeds, bran labor polybag, lime, paralon ring, rubbe and paper have no significant effect.

Tribal Areas

Economic and social inequality is consistently persisting in tribal region of Pakistan. People in the tribal region of Pakistan are living in deprived state whereby they lack even basic necessities in their lives. As described by Gul, the tribal areas are different than the rural areas because tribal areas are located in far flung mountainous terrain where accessibility to basic amenities is much lower than the rural areas [Gul (2013)]. In recent times, the Government of Pakistan initiated many efforts for provision of basic amenities in tribal areas as an essential component of development in the context of Millennium Development Goals (MDGs). However, according to John the desired state is yet to be achieved in tribal areas [John (2009)]. Tribal life is characterised by hardship and great insecurity especially for poor labour. Given the income vulnerabilities, the long run welfare is forgone for short run securities. Interruption, reduction or loss of earnings from the contingencies such as unemployment, underemployment, low wages, low prices and failure to find the market for the produce, old age, ill-health, sickness, disability etc. are the situations which call for social security and protection. As concluded by Talbot, this constant state of deprivation has generated deep rooted inequalities in the tribal society [Talbot (1998)]. People take rescue measures such as sending their earners to urban areas and if possible to foreign countries. Those who have lands and doing agriculture are the blessed one, although, the earning pattern is distorted due to law and order situation. To have an assessment of the overall economic inequality in the tribal region, author conducted a study in a small village Naryab which is located in the tribal region. Primary data was collected from the households physically and it was thoroughly analysed to conclude the pattern of inequality. This inequality was then mapped using latest mapping software “SURFER”.

The One

Agriculture has one of the highest shares of foreign-born and unauthorized workers among US industries; over three-fourths of hired farm workers were born abroad, usually in Mexico, and over half of all farm workers are unauthorized. Farm employers are among the few to openly acknowledge their dependence on migrant and unauthorized workers, and they oppose efforts to reduce unauthorized migration unless the government legalizes currently illegal farm workers or provides easy access to legal guest workers. The effects of migrants on agricultural competitiveness are mixed. On the one hand, wages held down by migrants keep labour-intensive commodities competitive in the short run, but the fact that most labour-intensive commodities are shipped long distances means that long-run US competitiveness may be eroded as US farmers have fewer incentives to develop labour-saving and productivity-improving methods of farming and production in lower-wage countries expands.
