Agriculture in Nepal
Pradeep Wagle
Background Information: Nepal
Nepal
Land locked country in South
East Asia.
Home for eight of the world's
ten tallest mountains, including
the highest point on Earth, Mount
Everest (8848 masl or 29029 ft).
Land area:
Nepal: 56,827 sq. miles
Oklahoma: 68,667 sq. miles
Population:
Nepal: App. 30 million
Oklahoma: 3.75 million
Climate:
• Elevation ranges from 70 m (230 ft) to 8848 m (29,029 ft)
above sea level.
• Tremendous variation in climate (tropical to temperate) as
a result of variation in altitude.
• Three distinct regions: Southern plain Terai (23%), Mid hills
(42%) and Mountains (35%).
• Nepal’s weather is generally predictable and pleasant.
There are four main climatic seasons:
(a) Spring : March-May
(b) Summer : June-August
(c) Autumn : September-November
(d) Winter : December-February
• June to September – rainy season (80% of annual rainfall)
Statistics
•
•
•
•
•
•
Cultivable land – 4 million ha (30% of total land)
Irrigated land – 1 million ha
Forest – 4 million ha (30 % of total land)
About 39% of Country’s GDP from Agriculture.
65% people derive livelihood from Agriculture.
Agriculture is largely based on low-value cereals and
subsistence production, with a mere 13 percent of
output traded in markets (The World Bank report).
Reasons for subsistence farming:
• Continuous land fragmentation (av. family holding acreage
less than 1 ha)
• Unavailability of other employments in rural areas
• Low investment capacity
• Lack of infrastructure and market opportunities
Major crops in Nepal
• Cereals: Rice, maize, wheat, millet and barley.
Rice is followed by maize and wheat.
• Vegetables: Potato, cabbage, cauliflower, radish,
tomato, beans, brinjal, chilli etc.
• Fruits: Mango, apple, peach, pear, litchi, orange,
banana etc.
• Cash crops: Oil seed crops, potato, tobacco,
sugarcane, jute, ginger, cardamom, tea etc.
• Increasing trends of growing vegetables and cash
crops in areas with road and market facilities.

Milk production: 1.5 million MT (1 million MT from buffaloes and 0.5 million
MT from cows)
Meat production: 0.25 million MT (Buffalo – 0.15 m MT, Goat – 0.05 m MT,
chicken and others – 0.05 m MT)

Rice
• Rice is grown in a diverse environments
ranging from tropical plains to foot of the
mountain at highest elevation (10,000 ft).
• Nepal’s average productivity (3 MT/ha)
whereas world average (4 MT/ha).
• Nepal has released fifty five (55) rice varieties
with full package of growing practices in the
last 40 years. New aromatic rice variety
released in 2008.
Reasons behind low production:
• Use of older generation seeds (most farmers
use their own seed for decades)
• Low doses of fertilizers
• Little use of improved cultivation practices
Corn
• The second most important cereal in Nepal.
• Grown from sub tropical to cool temperate climates (upto
8000 ft).
• Grown under rainfed condition.
• Over 25 vars. developed in Nepal for diff. regions
• Area under improved maize ~ 86%. However production
has not increased much (steadily increasing trend).
• Recommended spacing: 25 cm P-P, and 75 cm R-R
• Weeding at 5-8 leaf stage
• Apply urea (2-3 g) to each plant and earthing up at knee
height stage
Reasons behind low corn production
• Farmers use higher seed rates (>100%) but final
population 38% lower (after thinning) (Carlos U. Urrea,
CIMMYT – Nepal)
• Farmers use 2-3 g urea per plant (44 kg N/ha for 38000
plants) (National recom. for corn 100:80:60 NPK/ha)
• Poor adoption of new varieties
Lack of awareness of new varieties
Inaccessibility of seed of new variety (lack of active
seed providers at local level)
No/low cash economy
Prone to stored grain pests
Sources of farm power:
No. of tractors > 30,000 (2003)
(Manandhar, G. B.) *(Adhikary, S. K.)
Mechanization status
• In hills and mountains: Traditional tools and
implements existing (depended upon human
and animal power)
• Limitations for mechanization:
– Narrow terraces
– Lack of road networks and electricity
• Options:
– Improve hand tools and animal drawn implements
Mechanization (Cont.)
• In plain Terai: The use of mechanically
powered machines (tractors and power-tillers)
are gradually increasing for tillage, transport,
and threshing.
• Transplanting, weeding, and harvesting are
still done manually.

Obstacles to commercialization of
agriculture
• Mountainous terrain (restrict mechanization)
• Poorly developed road network (restrict access to
markets)
• Inadequate technical support
• Inefficient exploitation of water resources (< 40%
cultivable land irrigated)
• High land fragmentation, absentee landlordism/ unequal
land distribution
• Subsidies in India ’s agricultural sector mean that Nepal ’s
Terai region faces competition with Indian cereal
production
Possibilities:
• Increase yields through:
•
– Implementation of innovation techniques
– Use of genetically improved crop var. (GMOs)
– Fertilizer applications (soil and nutrition mgmt.)
– Shift from a subsistence to a commercial economy
Improve farmers’ economy:
– Commercial and industrial crops in Terai (Plain area).
– High value horticulture and cereal production in the
Mountains and Hills.
– Exports of off-season horticulture, niche products,
and non-timber forest products like medicinal plants.
– Organic production is practiced by default in Nepal.
Those produce needs to be certified.
