Amla (Indian gooseberry or Nelli) is a hardy,
drought tolerant crop, and it lends itself to high density
planting even in marginal and wastelands. “Through
systematic pruning techniques, the grafted trees of high
yielding varieties can be retained as bushes of profuse bearing
and such bushes are ideally suited for high density planting,” says
Mr. R. Kolandaisamy, an engineer turned –farmer at
Marungulam village near Thanjhar.
“High yielding amla varieties such as NA 7, Krishna
and Chakia are particularly suited for closer planting with
a spacing of 3 m by 3 m.
By adopting this spacing and following hexagonal or triangular
method of planting as many as 1200plants can be accommodated
in a hectare.
Some shade-tolerant medicinal plants such as Phyllanthus
sp (Keelanelli) and gulmeg can be grown as intercrop until
the amla trees reaches economic bearing age,” explained
this innovative and enterprising engineer.
Water Management
In this 25-hectare organic farm integrated with high-tech
nursery, he has laid a demonstration plot of 0.4 hectare
with more than 400 grafts of high yielding varieties of amla. “Water
management and special pruning techniques are crucial for
its success. I have laid drip system for the efficient discharge
of water right at the root zone, and adopt the unique pruning
to encourage lateral shoots for year-round profuse bearing
and easy harvesting,” points out Mr. Kolandaisamy.
Good quality and healthy grafts of the high yielding varieties
were planted in well-prepared fields. Small pits of 30 cm
by 30 cm were filled up with good organic manure, mulched
with coir pitch compost, neem cake and vermin compost to
increase the water holding capacity of the soil.
Biofertilizers such as Azotobacter, phosphobacterium and
Vesicular Arbuscular Mycorrhiza (Vam) were applied regularly
to boost the plant growth.
Initially, for the first three months, the drip-system was
set to deliver 25 litres per plant per day (depending on
the soil moisture regimen). When the plants were established,
the same quantum of water was used for irrigation on alternate
days.
After the first year of growth, when the grafts have put
down penetrating and extensive root systems, each plant would
need only 25 litres once a week, that too in peak summer.
The plants are systematically pruned, and fruiting can be
noticed even in young plants.
However, economically viable and bigger fruits can be got
from third year of planting. Each plant will yield about
25 kg of fruits a year. When the trees are five years old,
the yield per tree will gradually rise to 50 kg a year.
Cost per hectare
From the 8th year onwards, the average output per tree will
be about 100 kg a year, according to Mr. Kolandaisamy. The
cost of raising an amla plantation works out to Rs 1.25 lakh
per hectare.
The returns from the third year of planting, at an average
price of Rs 10 a kg of fruits, will be about Rs.2.5lakhs.
Cultivation of medicinal plants as intercrops would provide
returns till the amla comes to bearing and fetch assured
returns. “With sound management of natural resources
and good varieties, we can make every square centimeter of
our own farm yield rich dividends,” points out Mr.
Kolandaisamy.
