Introduction
In order to uplift the poor socio-economic conditions of the
farm women by raising the level of farm productivity, income
and employment with application of agricultural technologies
generated at research institutes, trainings are being conducted
at ICAR-Krishi Vigyan Kendra (KVK), Kattupakkam. Women are
employed for various farm activities like seed sowing, transplanting,
harvesting and maintenance of livestock and poultry. During these
operations, women face lot of problems related to health and also
time consumed for farm work is more than their normal activities.
Livestock management forms an integrated system for livelihood
for women in agriculture. Dairy farming is one of the important
activities where women spend lot of time for managing the animal,
feeding and milking. Amount spent for feeding the animal at present
cost nearly Rs. 50-60/animal/day yielding 3-4 liters of milk/day
along with green fodder feed @ 15kg/day.
In order to reduce the cost on feed and also to improve the
economic condition of the farm women and generate income Azolla
cultivation training was given. The present paper brings out the
importance of Azolla cultivation and income generated by the farm
women through its cultivation. Azolla is water fern, having symbiotic
relationship with bacteria Anabena Azollae. Azolla has very fast
growing character. It doubles its biomass in 3-5 days. Extensively
used as biofertilizer and green manuring for rice cultivation. The
ideal condition for growth is at Temperature 20 °C-28 °C with Light
50% full sunlight, Relative Humidity 65-80%, Water (in standing
condition) 5-12cm and pH 4-7.5. Azolla is very rich in proteins,
essential amino acids, vitamins (vitamin A, vitamin B12, Beta
Carotene), growth promoter intermediaries and minerals including
calcium, phosphorous, potassium, ferrous, copper, magnesium. On
a dry weight basis, Azolla has 25-35% protein content, 10-15%
mineral content, and 7-10% comprising a combination of amino
acids, bio-active substances and biopolymers [1].
Methods and Materials
Azolla cultivation training was given at ICAR-Krishi Vigyan
Kendra (KVK), Kattupakkam where in women engaged in
agricultural works under went training programmers. Method
demonstration of different ways of cultivation such as pit method,
silpauline sheet method, and cultivation in tubs, were demonstrated.
Based on the available land area, the trained women cultivated
Azolla in their farm for the purpose of feeding their dairy cattle.
The soil in the selected area was cleared of weeds and leveled.
Bricks were lined horizontally in a rectangular fashion. Silpauline
sheet of 2mX2m size was uniformly spread over the bricks in such a
way as to cover the margin of the rectangle made by the bricks. Ten
to fifteen kg of sieved soil was uniformly spread over the silpauline

Abstract
During the last few decades rural women are engaged in agricultural activities like seed sowing, intercultural operations, harvesting, storage of
grains and care and management of livestock and poultry. Women encounter drudgery in various works and spend more time in farm work than on
household activities. In order to generate income for farm women and to reduce the amount spent on livestock feed and also to improve their livelihood,
training on Azolla cultivation was conducted at Krishi Vigyan Kendra, Kattupakkam, Kancheepuram district of Tamil Nadu, India. Azolla is an aquatic
fern having symbiotic relationship with bacteria Anabena Azollae, which fixes the atmospheric nitrogen. Method demonstrations were conducted on
various ways of production. Based on the facilities available in their place, the trained women cultivated Azolla (viz., Pit size of 7X3ft and 7’’ depth) and
used it as feed for their livestock. Nearly about 2-3kg of Azolla was harvested from each pit. Azolla as a source of livestock feed reduced the feeding cost
which was spent for purchasing the feeding materials for poultry, goat and dairy cattle. By feeding of Azolla to dairy cattle, milk quality and yield has
increased (100-150ml per day per animal) considerably. The Azolla produced in excess was sold at the rate of Rs. 10/kg to the other farmers as Azolla
culture as well as feed for other cattles.
