Comparative Analysis of Temperature on Yield of Different Varieties of Oyster Mushroom Production

Oyster mushrooms are economical and most easily grown of all cultivated edible mushrooms. The crop has a range of varieties, differing in form, colour, texture and odor, which can be cultivated throughout the year under a diverse agro-climatic conditions. Three different oyster mushroom species viz., Hypsizygus ulmarius (var. CO2), Pleurotus eous (var. APK1) and Pleurotus florida (var. PF) along with three cropping rooms of varied temperatures was used for the study. Among the different cropping rooms, thatched shed with a temperature of 23o C recorded a highest yield of 748g, 712 and 673 g per 500 g of substrate by PF, CO 2 and APK 1 respectively than AC room and Concrete room. The temperature of the cropping room is inversely proportional to the yield of oyster mushroom. Hence, the thatched shed was best suited for oyster mushroom cultivation, which was both economic and easy to use.

CONSTRAINTS EXPERIENCED BY MUSHROOM GROWERS IN ADOPTING IMPROVED MUSHROOM PRODUCTION PRACTICES IN PUSA, BIHAR

Mushrooms (vegetarian meat/vegetable beef stick) is becoming fast popular because of its short time period between cultivation and harvesting; less initial investment and can be grown with locally available resources. Though more technology is available for boosting mushroom production, the yield so far achieved is not high. Hence, an attempt is made to find out the constraints faced by mushroom growers in adoption of improved mushroom production practices. Samastipur district of Bihar was purposively selected for the study because, Dr. Rajendra Prasad Central Agricultural University, a pioneer in mushroom production technology is located in the study area. 120 respondents from six villages of Pusa, Samastipur, Bihar forms the respondents of the present study. Primary data was collected from the mushroom growers and the responses were subjected to statistical analysis. The results indicated that unavailability of quality spawn, unavailability of skilled labor, absence of technical guidance, high transport cost, unavailability of storage facilities, high cost of spawn and long distance market were the most problematic constraints faced by the mushroom growers. Thus, it can be concluded that adequate extension service should be made available to make mushroom cultivation popular, market and marketing of the products.

A Study to Evaluate Growers Response in Vocational Training Programmes on Mushroom Cultivation Organized by Krishi Vigyan Kendra, Moga

Background: Mushroom production can play a vital role to alleviate poverty by generating employment prospects for jobless educated youth along with additional income in rural and semi-urban areas. The present study was conducted to find out the growers’ response to vocational trainings on mushroom production at Krishi Vigyan Kendra, Moga. Methods: The respondents consisted of 212 trainees who had undergone vocational training on mushroom production techniques from KVK, Moga between the years 2015-16 to 2019-20. Result: It was observed that pre-training knowledge score was not much satisfactory for all the aspects of training programme. However, the knowledge score gained by respondents after training was more satisfactory in all the aspects. The study revealed that exposure to training had increased the knowledge of participants regarding techniques of mushroom production by 80.75 per cent. The reason behind the satisfactory change in perception level might be due to well educational background, keen interest of participants and methods followed for technology transfer to the trainees. Some trainees even adopted mushroom cultivation as self-employment and set up their own units. The study revealed that the mushroom production training has created a favourable attitude among the trainees and also enhanced the economic level of beneficiaries who adopted it as a source of livelihood.

Development of a simple HPLC procedure for the determination of prochloraz residues in mushrooms

A simple HPLC-UV procedure is described in our paper which is suitable for the rapid and cost-efficient determination of prochloraz in mushrooms. Prochloraz is the only fungicide in EU which use is allowed in mushroom production. The aim of our work was the development of a simple method that is suitable for the control of this pesticide in everyday analyses during mushroom production. The procedure involves a simple sample preparation method based on solid-liquid extraction (modified QuEChERS extraction method EN 15662) followed by an HPLC-UV determination (recovery: 97–99%; limit of detection LOD: 0.01 mg/kg; limit of quantification LOQ: 0.05 mg/kg).

EVALUATION OF COST-BENEFITS OF OYSTER MUSHROOM PRODUCTION USING INNOVATIVE WATER HYACINTH SUBSTRATE FOR SUSTAINABLE DEVELOPMENT OF SME, KENYA

Purpose: The study did an evaluation of cost-benefits of oyster mushroom production using innovative water hyacinth substrate for sustainable development of Sme, Kenya. Methodology: The study employed the Benefit-Cost Analysis (BCA) technique for the evaluation Findings: Oyster mushroom is edible and belongs to fungi Kingdom and can play a key role in economic development of a country. It can also contribute immensely to human wellness through enhancement of body immune system when consumed regularly. Unique contribution to theory, practice and policy There is need to evaluate the Cost-Benefits of Oyster Mushroom Production Using Innovative Water Hyacinth Substrate for Sustainable Development of SMEs in Kenya. Objectives include determination of economic Net present Value (ENPV) and determination of Economic Benefit-Cost Ratio (EBCR). The significance of this study include control of Corona Virus (COVID-19) pandemic disease, poverty reduction, reduction of unemployment crisis and enhancement of sustainable business opportunity for SME.

Diversity in Mushrooms

This review paper present literature about the types and diversity of mushrooms which belong to a class of basidiomycetes of fungi. Mushrooms are spongy, fleshy, umbrella like structures which grow above the ground in dark and damp environment. The global production of mushrooms is 34 million tons out of which larger share is of china while in India Utter Pradesh is leading in mushroom production. Mushrooms had a history of being used as medicine and due to this, it is in high pharmaceutical demand now a days. Apart from edible and medicinal mushrooms which have high nutrient value there are mushrooms which are toxic in nature and are not safe for consumption.
