Mushroom Farming: The Fungal Goldmine

By Muhammad Zeeshan Farid & Dr Amjad Farooq

A global trend in agriculture has been a shift away from simple systems that rely on traditional crops, to those that increasingly seek new varieties of plants that cater to advanced dietary needs. To this end, scientists and growers have recommended several new crops that can augment the spectrum of agricultural produce.

Mushrooms, known locally as “khumbi”, are among this emerging cropping system. Mushrooms are essentially fungi, a group of organisms distinct from plants, animals and bacteria. They convert inedible plant waste into palatable food, which is savoured due to its biting texture and flavour. They form a complete diet as mushrooms contain essential vitamins and minerals, and are the best substitute for protein. They also contain traces of carbohydrates and fat.

Dr Amjad Farooq works as an assistant professor at the Department of Horticulture of the PMAS-Arid Agriculture University, Rawalpindi. He explains that, according to estimates, there are more than 1,500 types of mushrooms found on planet earth – some of them are edible, but others are poisonous. The four most popular types are the button or European mushroom, the Japanese mushroom, the Chinese mushroom and the oyster mushroom. The best quality mushrooms available in Pakistan are the oyster mushroom, the white mushroom, the golden oyster mushroom, the phoenix (grey) oyster mushroom and the pink oyster mushroom. These strains grow all over the country, and are available usually after the monsoon season.

Mushrooms can be cultivated between October and March. Cultivation does not require land and can be grown in small houses and huts as a part-time activity. Mushroom cultivation does not require full time-labour, and all family members can look after different operations easily. There are two modes of propagation for a mushroom crop: open-air field cultivation and controlled cultivation.

After seven days of cultivation, small pin-like heads emerge from the mushroom, which turn into more mushrooms after three to five days. Branches which grow five to seven inches long, called flushes, are removed from the plants and dried. These can be used in cooking, or can be sold in the market. Flushes keep regenerating from the plant after every ten days of the removal of old ones: the cycle is very short, and as a result, highly productive.

“A single flush or branch of mushroom can yield more than half a kilogramme (kg) of edible food after each week for three months,” says Dr Muhammad Nadeem, from the Institute of Horticultural Sciences, University of Agriculture Faisalabad (UAF).

Thus, 100 beds of mushroom can yield more than 120kg of mushrooms a week. At the rate of Rs150 per kg, they can generate a lump sum profit of Rs18,000 a week, or Rs72,000 in a month. Dr Nadeem says the “production of mushrooms touches approximately 1.5 million tons in the world, while about 90 tons of mushrooms are exported to Europe from Pakistan every year.”

Oyster mushrooms currently sell for around $6 a pound in the US. A growing area of around 200 square feet can produce 800 pounds per crop; or 5,000 pounds of mushrooms per year. This is worth almost $30,000 at current prices. It’s clear that growing oyster mushrooms for profit is a great way to make some extra cash.

However, it should be kept in mind that, given the large variety of poisonous strains of mushrooms, spawn should be developed only under the supervision of experts. It is available at the UAF, the National Institute of Biotechnology and Genetic Engineering, the Ayub Agricultural Research Institute and other government research stations.

Farmers who wish to cultivate mushrooms should book spawn well before the cultivation season, because it may not be readily available during the peak demand period. The UAF laboratory has developed some thermo-tolerant strains of the most widely grown button mushroom (Agaricus bisporus) and the oyster mushroom (Pleurotus cystidiosus).

As basic training is required for profitable mushroom cultivation, the Continuing Education Department of the UAF offers a short course suited for farmers. Furthermore, the UAF’s Mushroom Lab can be contacted for guidance and information, and it can give proper suggestions and recommendations to those willing to invest in this lucrative business.

Flowers: Adding Rainbow Colors To Landscape

By Adnan Younis, Dr. Atif Riaz and Dr. Muhammad Nadeem, Institute of Horticultural Sciences, University of Agriculture Faisalabad Pakistan

Annual flowers are non-woody plants that complete their life cycle in one season, ending with seed production. Annual flowering plants can be propagated through seeds, unlike many biennials and perennials. They are thus best suited to environments that have a short growing season. Annual flowers can play an imperative role in a well-designed landscape and are an excellent way to draw attention to building and home entrances, walkways and outdoor living spaces and to provide homeowners and visitors with pleasing welcome.

Selection of flowers for garden needs a careful attention and should be carried out on the basis of plant height, color of flowers, nature of growth, and type of environment they need. Typically, a flower border has the tallest plants in the back, medium height plants in the middle and short plants in the front. The style of the annual bed should be compatible with the overall style of your landscape design. Plantation can be done either in a formal or informal design, depending on the arrangement of the planting. In formal designs are made up of geometric lines and symmetry, with strong focal points that attract the eye. In contrast, informal designs have curved, flowing lines and natural forms, follow natural terrain and create an asymmetrical balance within the planting.

Before planting flowers, the physical characteristics of the site must be evaluated. Check the site's soil type, fertility status, drainage and its exposure to sun and wind. Compare site characteristics with specific plant requirements. An annual plant adapted to site conditions grows and flowers more vigorously and has fewer pest problems. Some plants intolerant of heat and sun may perform adequately when planted in part shade. Annual flowers offer flexibility in landscape design and planting can be changed each growing season, creating an entirely new design. As a part of their quick change potential, annuals are called “Temporary Visitors” of Garden.

Designing a garden with plants exhibiting many different colors requires some coordination and color schemes. Consider the color of the house and any other fixed structures such as fences or utility buildings. Pink flowers can be used against a brick walls with orange tones would not produce a pleasant combination. Mostly it is more recommended to use masses of a single color instead of mixing colors in flowering beds because a mass planting of a single color or planting in bands of colors will produce a stronger impact.

It is important to look location and how the flowers will be viewed from different angles. Bright colors stand out, while dark colors fade into the background. Bright colors catch attention to an area, so do not use red and yellow flowers near an eyesore or unattractive area. Bright colors seem closer, while dark colors make the area appear further away. White is the last color to fade from sight as darkness falls and thus is good for areas used at night.
