Subsidy for Spirulina Cultivation

Introduction to Spirulina Cultivation

Spirulina is a blue-green algae that has been used as a dietary supplement for its high nutritional value and health benefits. Spirulina is rich in content such as protein, vitamins, minerals, antioxidants, and essential fatty acids. Spirulina can help improve immunity, reduce inflammation, lower cholesterol, and prevent anemia. Spirulina can used as a natural food colorant and animal feed.

Spirulina cultivation is a profitable and sustainable business opportunity for farmers in India. It can be grown in any type of water, such as salty water, rainwater, fresh drinking water, etc. Spirulina requires a high pH level of 9-11, which prevents the growth of competitors or pathogens in the culture medium. It can be harvested every 10-15 days throughout the year, with a yield of about 10-15 kg per 1000 liters of water.

Indian Government Schemes Encouraging Spirulina Farmers

The Indian government has launched several programs to encourage the development of spirulina because it understands its importance. Farmers interested in spirulina cultivation may access training programs, incentives, and technical support from various agricultural departments and research institutes.

The National Horticulture Mission (NHM) provides a 50% subsidy for setting up spirulina production units, including tanks, pumps, filters, agitators, etc.
The Rashtriya Krishi Vikas Yojana (RKVY) provides a 75% subsidy for spirulina cultivation under the micro-nutrient security component.

How to Start a Spirulina Farm

Choose a Suitable Location: You need to have a land area of at least 0.1 hectares with an assured water supply and electricity connection. The land should have a flat surface and good exposure to sunlight. The water source should be free from contamination and have a pH of 8.5 to 11.

Construct a Container: You need to construct a container for spirulina cultivation, such as a concrete tank, a plastic tank, or a pond. The container should have a depth of 15 to 25 cm and a surface area of 100 to 200 square meters. The container should be lined with a black polythene sheet to prevent algae growth on the walls and bottom.

Prepare the Culture Medium: You need to prepare the culture medium for spirulina growth, which consists of water and nutrients. The water should be filtered and sterilized before adding the nutrients, which can be either chemical or natural minerals, such as urea, sodium bicarbonate, potassium nitrate, etc. The culture medium should have a salinity of 10 to 30 ppt and a pH of 9 to 10.

Inoculate the Spirulina: You need to inoculate the spirulina into the container, which means adding a small amount of spirulina culture to start the growth process. You can obtain the spirulina culture from a reliable source, such as an agricultural department, a research institution, or an existing farmer. The inoculation rate should be 10% of the container volume.
