INDIAN agriculture has challenge of providing national as well as household food and nutritional security to its teeming millions in a scenario of plateauing genetic potential in all major crops. declining productivity in vast tracts of rainfed/ dryland areas constituting approximately 44.2% of net cultivated area. Wide-spread occurrence of ill-effects of green revolutiontechnologies in all intensively cultivated areas is threatening thesustainability of the important agricultural production systems andnational food security..
The human population of India has increased to 1210.2million at a growth rate of 1.76 per cent in 2011 and isestimated to increase further to 1530 million by 2030.On the other hand our national food grain production for past3-4 years is hovering around 234 million tonnes.There are projections that demand for food grains wouldincrease from 234 million tonnes to 345 million tonnes in2030.The average size of the landholding has declined to 1.21 haduring 2009-10 from 2.30 ha in 1970-71.
Declining size of landholdings without any alternativeincome augmenting opportunity is resulting in fall offarm income and causing agrarian distress.To meet the multiple objectives of poverty reduction,food security, competitiveness and sustainability,several researchers have recommended the farmingsystems approach to research and development.
Farming systemFarming system is the scientificintegration of different interdependentand interacting farm enterprises for theefficient use of land, labour and otherresources of a farm family whichprovide year round income to thefarmers specially located in thehandicapped zone.
What is itFarming system approach envisages theintegration of agroforestry, horticulture, dairy,sheep and goat rearing, fishery, poultry, pigeon,biogas, mushroom, sericulture and by-productutilization of crops with the main goal ofincreasing the income and standard of living ofsmall and marginal farmers.
Role of Farming System Food security Provide balanced food Quality food basketHigh productivity and enhanced farm income Effective recycling of resources Minimizing environmental pollution Employment generation
Role of Farming System Food security: Food security is defined as the balanced food supply and effective demand for food. Ensuring food security to the individual wards off the gender- based intra-household discrimination. Thus food security needs to be redefined as “livelihood security for the household and all members within, which ensures both physical and economic asses to balanced diet, safe drinking water, environmental sanitation, primary education and basic health care.

Economic and ecological access to food could be onlyensured by adopting farming system approach consisting of: Change from commodity-based to resource- based planning. Integrated use and management of land, water and human resources to maximize income and employment.
Provides Balanced FoodThere is need of farming system which has severalcomponents like dairy, poultry, goatry, fisheries etc. alongwith crop production.In this way, farming system would not meet the food for butalso cater the need of protein, fat, vitamins and mineralsrequired for good health.Conjunction of horticulture and agroforestry with croppingwould ensure the seasonal access to fruits, fuel, fodderand fibre.
Quality food basket As the living status is improved the requirement of cereals will be decreased and supplemented by other items viz. milk, egg, meat, fruit etc. Integration of allied enterprises with cropping increase the nutritive value of the products. Cropping with pigeon+fish+mushroom founds to have the highest protein of 1963 kg. Integration of cropping with fish + mushroom and pigeon/poultry could result in 31 to 52 % higher protein yield than cropping alone.
Higher productivity and enhanced farm income• Integration of fish in rice system decreasing the rice grain yield due to presence of fish trenches occupying 10% of the rice area, however, additional income increased.• The profit can be increased more when fish, vegetable system and livestock include in rice – rice farming system.

Effective recycling of resourcesThe effective recycling of farm resources is possible byadoption of farming system research.Crop by-product is utilized as fodder for animals, andanimal by-product i.e. milk, and dung may be utilized forincreasing income and soil fertility, respectively.

Minimize environmental pollution • In Punjab, Haryana and western Utter Pradesh, burning of rice residue is common practice, which increased the concentration of green house gases in atmosphere, in addition to huge amount of nutrient loss. • Such situation could be avoided by introduction of some more enterprises like animal husbandry on the farm. • Rice straw may be used as animal feed.
Employment generation• Since crop based agriculture is highly season specific and time bond, the intensity of labour requirement increases during sowing and harvesting time of crops.• For rest of the time farmers sitting idle if they do not have off-farm activities. This leisure time could be utilized effectively by adoption of farming system, which keeps the whole family busy throughout the year.

Farming System ResearchFarming System Concept was developed in 1970.It is designed to understand farmer priorities, strategies and resourceallocation decisions.Used in conjunction with on-farm research to identify and adopttechnologies useful to location specific problems of farmers.Farming systems research and development approach associated withsmall farmers and focuses on their conditions and aspirations.Its goal to develop sustainable land use system which will optimizeresource use and increase income and employment for farm families.
Farming System Research For Different Agro Climatic Zones In India • Pastures with forestry, goats,High altitude cold rabbits, and settled agricultural deserts crops like millets, wheat, barley, and fodders. • Animal husbandry with the camels, Arid and desert sheep and goats, and growing with region fodder and field crops. • Horticultural crops as a major Western and component and agriculture mainlycentral Himalayas on the hill terraces and slopes with maize, rice, wheat, pulses and fodder crops.
• Primitive crop husbandry with rice, Eastern millets, pulses etc. Agro forestry Himalayas system are also common. Piggery and poultry are the chief livestock activity. • Intensive crop husbandry like rice-Indo-Gangetic wheat-maize/mustard/pulses and Plains livestock, dairy, cattle and buffaloes. Central And • Cotton-sorghum-millets/pulses with Southern dairy cattle, sheep and goats and Highlands poultry are the secondary livestock and animal husbandry enterprises.
• Major activity on plantation crops, cultivating rice and pulses are the secondary agricultural activity. Cattle, Western Ghats sheep and goats are the livestock components which in most parts, are maintained as large herds. • Rice cultivation with other enterprisesDelta And Coastal like fishery, poultry and piggery, etc., Plains capture fisheries of marine ecosystem is a specialized enterprise.

Future research thrust Need to study the sustainability of the identified systems under different topographical situations in the long run including high value crops. Need to study the nutrient dynamics of soil with continuous cropping and recycling of manurial resources with different systems over time. Modeling of the identified farming system options to suit a given agro-climatic and socio-economic situation. Need to identify the constraints in adoption of identified farming systems by the farmers for further refinement.
ConclusionEfficient utilization of scarce and costly resources is the need of the hour tomake crop production a viable proposition in the present day competitivescenario.Following the concept of Integrated farming systems through supplementationof allied agro-enterprises by recycling the waste of one enterprise in another isa right step in this direction.It provides alternate and sustainable avocation to marginal and sub-marginalfarmers. Fruit, mushroom, apiary, animal production and poultry have beenmore viable with them.
The crop residues and biomass available in plenty in the cropproduction system need to be properly managed to harness fullbenefits.Improving the integrated approach not only enhances farmincome but also overcomes environmental pollution.A better planning and utilization of the available resources willusher in bright prospects for the farm economy as a whole.
