Lac Farming Business | Kerria Lacca Farming | Shellac Production | লাক্ষা চাষ

Shellac is a resin secreted by the female lac bug, on trees in the forests of India and Thailand. It is processed and sold as dry flakes, which are dissolved in ethyl alcohol to make liquid shellac, which is used as a brush-on colorant, food glaze and wood finish. Shellac functions as a tough natural primer, sanding sealant, tannin-blocker, odour-blocker, stain, and high-gloss varnish. Shellac was once used in electrical applications as it possesses good insulation qualities and it seals out moisture. Phonograph (gramophone) records were also made of it during the 78-rpm recording era which ended in the west during the 1950s.

From the time it replaced oil and wax finishes in the 19th century, Shellac was one of the dominant wood finishes in the western world until it was largely replaced by nitrocellulose lacquer in the 1920s and 1930s.

Introduction:

Shellac, an important resin of commerce is secreted by tiny gregarious lac insects, Kerria lacca (kerr), (Homoptera: Techardidae) thrining on various host plants. In India, two strains of this species kusmi and rangeeni are mainly grown on three tree host species viz., Kusum(Schleichera oleosa), palas(Butea monosperma) and ber(Ziziphus mauritiana) found scattered in forest and farmers’ holdings in Jharkhand, Madhya Pradesh, Chhattisgarh, West Bengal, Orissa and parts of other states. Presently, plant population of above lac hosts is decreasing due to deforestation and unawareness of economic exploitation. Raising of new plantation of these species is time consuming because of their slow growing habit besides certain other limitations with regards to crop management, lac culture operations and protection. A bushy host plant species, Flemingia semialata Roxb. (Leguminosea: Papilionacae), has been identified and field tested as a potential fast growing host for intensive lac cultivation during winter season lac crop of Kusmi strain (aghani) fro increasing lac production to match pace with the growing global demand of lac.
Shellac is a natural resin produced by the scale insect Laccifer lacca, which is a parasite of certain host trees. Used mainly to make lacquer and glossing material, lac is a commodity that has been traded in the international markets since the early 20th century. Lac is also used today in electronics, printing, textile, clothing, cosmetics, and food. The United States and Japan are major importers of lac resin, while India and Thailand are the leading exporters

Flemingia Semialata is Host Plant of Shellac:

Flemingia Semialata

Flemingia semialata is a perennial, erect, quick growing and iput responsive lac host, grows up to height of about 3.0 m depending upon plant management. It has well developed root system which comprises tap roots and nodulation on the root hairs. Leaves are digitately trifoliate and leaflet elliptic acuminate. Flowering takes place during October-November and seeds ripen during the months January-February. The pods are oblong green, tomentose, swollen, sac like structure bearing two seeds. Seeds are round, black with sporadic white spots on the outer skin. One kg. seed contains approximately 27-30 thousand seeds. It has capacity to fix atmospheric nitrogen, there by enriching soil fertility. In view of being responsive to high coppicing, manageable stature, this plant species is gaining popularity for production of superior quality winter season kusmi lac under rainfed condition.

This host is highly suitable for production of good quality Kusumi Lac crop during winter season (Agahani). However, Kusumi lac crop can also be cultivated on this host during summer season (Jethwi), but the productivity is a bit less.

As this plant attains very short height, it can be used for the purpose of intercropping with different crops and can provide extra benefit to the farmers. Moreover, it can be grown in soil having medium fertility, partial sloppy land with degraded soil of low fertility and slightly acidic condition.

The yield of Kusami lac earns Rs. 4 to 5 lakh per hectare Flemingia semialata and generates 620 days of employment in a year. The crop cycle of lac cultivation is of four months duration and since Flemingia is ideal in lac cultivation.

Easy Tips and Ideas to Start Business

Although anyone can start a business, many people fail because of a bad product or improper research. If you want to start your own business, you can improve your chances for success before you even begin. In order to make your business successful, start strong and make sure that your idea will hold out for the long haul.

Have a Good Product

Ensure that you plan to sell something useful. Although you may think that your product is important or special, that doesn't mean the general public will agree. Ask friends, family and strangers what they think of your product. If they don't seem that interested, ask them why. With their suggestions, you can either improve the product or scrap the idea completely. According to Brad Sugars of Entrepreneur magazine, most small businesses fail because they sold a product that didn't have an adequate market. This also applies to small businesses that provide a service. A lawn-care business might be useful for part of the year in a northern state, but it is in-demand year-round in the south. Consider whether people will actually want to use your service and get constructive advice from those not afraid to give their opinion.

Research Local Businesses

Research local companies before starting up your own business. This will not only give you an idea of the amount of competition you will have, but it will also help you price your product or service. If you're looking to start a wedding photography business, you may find during your research that the market is over-saturated in your area. If not over-saturated, you should contact each business and ask them for a price list. Alter your prices so you can stay competitive with the competition in town. Researching similar local businesses will also help you decide where to locate your business location. Try not to start up a store or office close to another business of your type. If your small business is located away from similar business types, this will cause locals to choose you over businesses that are farther away from where they live.

Get Professional Advice

You may know someone who has started their own successful business. Ask him for advice and listen to his stories of how he started his company. You may gain useful advice on the good and bad ways to start a business. Local entrepreneurs can also introduce you to local product providers or advertisers that you may not have met without their help. Accept any advice with open arms, especially if the advice is coming from someone successful in the area.

How to Calculate Business Start Up Costs

Starting a business in no easy endeavor. It takes a great deal of research, perseverance and hard work. While sweat equity will make your small business more successful, you will most likely need real capital to get the business started. Before you start raising capital and/or investing your own funds, the first thing you need to do is determine the total start-up costs.

Step 1

Determine your costs of sales. For most small businesses this means inventory, the cost of raw materials, manufacturing equipment, shipping, packaging, and warehousing. However, not all businesses sell products. In this case, the cost of sales is primarily the direct labor involved in making the sale. For example, to open a small shoe business entails purchasing enough inventory ($10,000) to stock the store.

Step 2

Determine professional fees. Planning your business structure, i.e., limited liability corporation or general partnership, means hiring an attorney. There may also be the need to pay an attorney for help with establishing trademarks, copyrights, and patents. In this scenario, that puts total professional fees at an estimated $20,000.

Step 3

Determine technology costs. Technology can greatly reduce the cost of labor for small business if used effectively. Most small businesses require computers, printers, cell phones, website development, Internet access, software applications, information security, data storage, and outsourced information technology (IT) consulting. If the cost of technology is $10,000 to start, add an additional $5,000 a year for maintenance (hint: maintenance is not included in start-up costs).

Step 4

Determine administrative costs. This varies with business types and may include items such as business insurance, office supplies, product packaging, parking, rent, express shipping, desks, chairs, fax machines, phones, or anything else necessary to operate the business daily. A good estimate for start-up administrative costs would be $5,000 for the first six months.

Step 5

Determine initial sales and marketing costs. Now that you have your product, you need to let folks know about it. Sales and marketing costs generally include marketing materials for presentations, printing stationery, business cards, advertising, trade show events, and public relations. These initial sales and marketing costs can add up to $3,000.

Step 6

Determine the wages and benefits needed to secure a staff. This includes employee salaries, benefits, workers compensation, and payroll taxes. Let's put the cost of wages and benefits estimated at $20,000 for the first three months of business.

Step 7

Add all costs associated with starting the business for a total. Be sure to only include business start-up costs that will be incurred in the first three to six months of operations. For this example, the calculation is: $10,000 + $20,000 + $10,000 + $5,000 + $3,000 + $20,000 = $68,000.
