NABARD Grade-A Exam : Notes on Agriculture & Rural Development | Agro Climatic Zones

No comments
The upcoming important exams are NABARD grade A and grade B, in which there is a section Agriculture & Rural Development (with a focus on Rural India) having high weightage of 40 marks. So, for the same, it becomes really important to have an in-depth knowledge of the various terminologies and practices involved in agriculture. Further its imperative to be aware of the present scenario of Indian Agriculture and the state of Rural Development in India. To help you with this, today, we are providing you with all necessary information related to the mentioned field which will help you to fetch some good marks.


An “Agro-climatic zone” is a land unit in terms of major climates, suitable for a certain range of crops and cultivars. The planning aims at scientific management of regional resources to meet the food, fiber, fodder, and fuelwood without adversely affecting the status of natural resources and environment.
Agro-climatic conditions mainly refer to soil types, rainfall, temperature and water availability which influence the type of vegetations. An agro-ecological zone is the land unit carved out of agro-climatic zone superimposed on landform which acts as a modifier to climate and length of growing period.
The main objectives of agro-climatic regions are:
(i)To optimise agricultural production
(ii)To increase farm income
(iii)To generate more rural employment
(iv)To make a judicious use of the available irrigation water
(v)To reduce the regional inequalities in the development of agriculture.
The Planning Commission has categorised 15 agro-climatic zones in India, taking into account the physical attributes and socio-economic conditions prevailing in the regions.


Names & States
Major Crops; Soil
Western Himalayan Region: Jammu and Kashmir,
Uttar Pradesh
Rice, maize, barley, oats and wheat. Apple orchards and other temperate fruits such as peaches, apricot, pears, cherry,almond, litchis, walnut, etc. Saffron is grown in this region.
Research in better seeds and extension service for agricultural development are required.
Eastern Himalayan Region: Assam, Sikkim, West
Bengal and all North-Eastern states
The main crops are rice, maize, potato, tea.There are orchards of pineapple, litchi, oranges and lime.
Jhuming(shifting cultivation) prevails in the hilly areas.
Infrastructural facilities in the region need to be improved and shifting cultivation controlled by developing terrace
Lower Gangetic Plains Region:West Bengal
Rice is the main crop which at times yields three successive crops (Aman, Aus and Boro) in a year. Jute, maize, potato, and pulses are other important crops.
Region has adequate storage of groundwater with high water table.
Improvement in rice farming, horticulture(banana, mango and citrus-fruits), pisciculture,poultry, livestock, forage production and seed supply.
Middle Gangetic Plains Region:
Uttar Pradesh, Bihar
Rice, maize, millets in kharif, wheat, gram,barley, peas, mustard and potato in rabi are important crops.
Fertile alluvial plain drained by the Ganga and its tributaries.
Alternative farming systems, and utilising chaur lands to boost agricultural production.
Reclamation of user lands, wastelands, and fallow lands for agriculture and allied activities (agro-forestry, silviculture,
floriculture etc.)
Upper Gangetic Plains Region: Uttar Pradesh
Wheat, rice, sugarcane, millets, maize, gram,barley, oilseeds, pulses and cotton are the main crops.
Soil is sandy loam. Canal, tube-well and wells are the main source of irrigation.
Modernising traditional agriculture, dairy development, and horticulture.Developing multiple mixed cropping patterns.
Trans-Gangetic Plains Region: Punjab, Haryana,
Delhi and Rajasthan
Important crops include wheat, sugarcane, cotton,rice, gram, maize, millets, pulses and oilseeds
The soil is alluvial which is highly productive.
Canals and tube-wells and pumping sets have been installed by the cultivators
and the governments
Development of genotypes of rice, maize and wheat with inbuilt resistance to pests and diseases.
Promotion of horticulture; supply of quality seeds of vegetables and planting material for horticulture crops
Eastern Plateau and Hills Region:
Maharashtra, Uttar Pradesh, Orissa and West
Rainfed agriculture is practiced growing crops like rice, millets, maize, oilseeds, ragi, gram and potato.
Soils are red and yellow with occasional patches of laterites and alluviums. The region is deficient in water resources due to plateau structure and non-perennial streams.
Cultivation of high value crops of pulses like tur, groundnut and soyabean; improvement of indigenous breeds of cattle and
buffaloes, extension of fruit plantations, renovation including desilting of existing tanks and excavation of new tanks
adopting integrated watershed development approach to conserve soil and rain water
Central Plateau and Hills Region:
MP, Rajasthan, Uttar Pradesh
Crops grown are millets, wheat, gram, oilseeds,cotton and sunflower
Soils are mixed red, yellow and black.
scarcity of water
Water conservation through water saving devices like sprinklers and drip system; dairy development, crop diversification,
groundwater development, reclamation of ravine lands
Western Plateau and Hills Region:
Maharashtra, Madhya Pradesh and Rajasthan
Wheat, gram, millets, cotton,
pulses, groundnut, and oilseeds are the main crops in the rain-fed areas,
while in the irrigated areas, sugarcane, rice, and wheat, are cultivated. Also grown are oranges, grapes and bananas.
Increasing water efficiency by popularizing water
saving devices like sprinklers and drip system; lower value crops of jowar, bajra and rainfed wheat should give way to high-value oilseeds
Southern Plateau and Hills Region:
Andhra Pradesh, Karnataka, Tamil Nadu
Millets, oilseeds, pulses, coffee, tea, cardamom and spices are major plantations.
Encouraging horticulture, dairy development and poultry farming
East Coast Plains and Hills Region:
Orissa, Andhra Pradesh, Tamil Nadu and
Main crops include rice, jute, tobacco,
sugarcane, maize, millets, groundnut and oilseeds
Soils are alluvial, loam and clay and are
troubled by the problem of alkalinity
Increasing cropping intensity using water-efficient crops on residual moisture, discouraging growing of rice on
marginal lands and bringing such lands under alternate crops like oilseeds
and pulses
West Coast Plains and Ghat Region:
Tamil Nadu, Kerala, Goa, Karnataka, Maharashtra
Rice, coconut, oilseeds, sugarcane, millets,
pulses, cotton, plantation crops and spices are the main crops.
Soils are laterite and coastal alluvial
Focus attention on raising of high value crops infra-structural facilities and promotion to prawn culture
Gujarat Plains and Hills Region:
Groundnut, cotton, rice, millets, oilseeds, wheat and tobacco are the main crops. Soils are regur and alluvium
Canal and groundwater management, rain water
harvesting and management, dry land farming, agro-forestry development,
wasteland development
Western Dry Region: Rajasthan
Bajra, jowar, and moth are main crops of kharif and wheat and gram in rabi
Rainwater harvesting, increasing yield level of horticultural crops, adopting high-quality germ- plasm in cattle to improve
their breed;
The Islands Region:
Andaman and Nicobar, Lakshadweep
Main crops are coconut, rice, maize, millets, pulses, arecanut, turmeric and cassava
Crop improvement, water management; multi-purpose
fishing vessels, suitable infrastructure for storage and processing of fish
