Cause of Low Productivity in Agriculture
 Various factors responsibile for low productivity of Indian agriculture are —
 (i) Because of the excessively increasing population our land resources have been used extensively thereby leading to loss of fertility of the soil.
 (ii) Reckless deforestation has led to declining flora so that less humus is being added to the soil through normal process. Human deficiency is resulting in the increasing soil temperature; and hence making the pre-monsoon cropping more and more difficult. Human deficiency is resulting in the increasing soil temperature; and hence making the pre-monsoon cropping more and more difficult. Human deficiency also causes reduction in the capacity of soil to hold moisture.
 (iii) Increased construction of roads, railways and canals, have disturbed the natural drainage system or normal flow of rain water thus bringing heavy floods. This results in large scale damage to kharif crops and considerable late sowing of rabi crops.
 (iv) Marginal and sub-marginal lands, which are generally inferior and yield less, are being cultivated due to increasing population pressures.
 (v) As a consequence of recent land reforms, land is passing (by purchase, lease or allotment) to classes which have no agricultural traditions and in most of the cases lack the necessary technical knowledge and, therefore, are inefficient farmers.
 (vi) Due to soil erosion, growing salinity, aridity, alkalinity and semi-desert conditions, cultivable land is turning into barren waste.
 (vii) Subsistence type of farming results into deficit agricultural economy as agriculture remains low income occupation which follows low savings, low investment and low agricultural incomes.
 (viii) Uncertain and erratic rainfall, unfavourable weather conditions and pest and diseases of crops reduce crop yields.
 (ix) Small, uneconomic and fragmented holdings make the use of modern methods of cultivation difficult.
 (x) Traditional equipments, inadequacy and obsolete nature of tools are also a contributory factor.
 (xi) Lack of organisation and leadership in Indian agriculture causes heavy erosion of resourceful talent from agriculture which considerably reduces the capacity of farming community to compete and progress.
 (xii) Inadequacy of irrigation facilities, lack of and high prices of manures and fertilisers.
 (xiii) Concentration of land in a few hands, below which are a large number of small and medium cultivators, result into non-utilisaiton of land to its fullest extent
 (xiv) Restricted storage facilities depresses the price in market; and bad communication and imperfect marketing facilities prevent realisation of a fair price for the produce.
 (xv) Inadequacy of non-farm services like provision of cheap credit and the resultant indebtedness and poverty of the peasant as well as lack of marketing facilities restrict improvement in techniques of production.

Reorganisation of Indian Agriculture
 In India the agrarian system needs reorganisation according to the present day needs and conditions on improved lines. Increased agricultural productivity is essential for the following three reasons —
 (i) to supply an economic surplus that can be consumed or used for further production in agriculture or transferred out of agriculture to provide capital for industrial growth and to meet the expanding consumption needs of the urban population;
 (ii) to make possible the release of labour and other resources for use in non-agricultural sectors; and
 (iii) to increase the purchasing power of rural people, expand markets for industrial goods and help to bring about needed changes in the national income organisation.

 

The basic conditions for improving productivity in agriculture, according to FAO are —
 (i) reasonably more control to be applied on increasing population; 
 (ii) stable prices for agricultural products at a remunerative level;
 (iii) adequate marketing facilities;
 (iv) satisfactory system of land tenure;
 (v) provision of credit on reasonable terms especially to small farmers, for improved methods of production;
 (vi) provision of production requisites (fertilisers, pesticides, improved seeds, etc.) at reasonable prices;
 (vii) provision of education, research and extension of agro-economic services to spread the knowledge of improved methods of farming;
 (viii) the development of sources, by the State, which are beyond the powers of individual farmers, such as large-scale irrigation, land reclamation or resettlement problems; 
 (ix) extension of land use and intensification and utilisation of land already in use through improved and scientific methods of cultivation; and 
 (x) diversification of farm production i.e., besides cultivation of crops, dairy, poultry and fishing industries should be developed.
  The above factors will not only help in maintaining but also in developing soil productivity to the highest practicable level thereby stabilising our agrarian economy and improving the plight of rural India.
 The physical resources of soil, water and climate are sufficient to yield at least double, perhaps more than double the current production with full use of machines, chemicals, sufficient water supply and a combination of other good management practices.

Soil and Water Conservation
 Launched from the very First Plan, soil and water conservation programmes are one of the essential inputs for increasing agricultural output in the country. These programmes emphasise on development of technology for problem identification, enactment of appropriate legislation and constitution of policy coordination bodies. Main objectives of the scheme in operation are —
 (i) to slow the process of land erosion and degradation;
 (ii) to restore degraded lands to ensure regeneration;
 (iii) to improve and ensure availability of water and soil moisture;
 (iv) to create micro level irrigation through water harvesting;
 (v) to enhance internal fertility of soil through organic recycle.
 (vi) to enlarge effective productive exploitation zone to the deeper soil profile by adopting mixed and companion farming system;
 (vii) to increase aggregate bio-mass production;
 (viii) to generate employment through continuous adjustments in optimum land use planning and to ensure collective security against recurring droughts and floods.
 Programmes sponsored by Soil and Water Conservation Division at the national level are checking problems like water and wind erosion, degradation through water logging, salinity, ravines, torrents, shifting cultivation, coastal sands in addition to declining man-land ratio, increasing and competing demands for land, diversion of arable land and loss of productivity.
 The major central/centrally sponsored schemes have been directed towards : checking premature siltation of the multipurpose reservoirs; mitigating the flood hazard in the productive plains; resettling of shifting cultivators; and restoring degraded lands.
 The following measures undertaken for soil and water conservation may be noted.
 1. A scheme for soil conservation in the catchments of river valley projects was launched in the Third Five Year Plan to prevent premature siltation of multipurpose reservoirs.
 2. A centrally sponsored scheme for reclamation of alkali (usar) soils, launched during Seventh Plan, continues in Haryana, Punjab and Uttar Pradesh. The components of the scheme include assured irrigation water, on farm development works like land levelling, deep ploughing, community drainage systems, application of soils amendment, organic manure etc. An area of 3.36 lakh hectare of land has been reclaimed upto 1993-94.
 3. A scheme for control of shifting cultivation was implemented with cent percent central assistance in all the seven north-eastern states, Andhra Pradesh and Orissa till 1990-91. From 1991-92 the scheme was transferred to the state sector. The scheme has been revived for the north-eastern states only from 1994-95.
 4. A scheme of Integrated Watershed Management in the catchments of flood-prone rivers was launched during the Sixth Plan in eight flood prone rivers of the Gangetic basin covering seven States and Union Territories. The scheme aims at enhancng the ability of the catchment areas to absorb larger quantity of rain water, thus reducing erosion, silting and the consequent fury of floods.
 5. All India Soil and Land use Survey Organisation (AISLUSO) with its seven regional/sub-regional centres does catchment delineation and fixing of priorities for watershed development.
 6. The National Land Use and Conservation Board (NLCB) is concerned primarily with national land use policy. It coordinates the work of State Land Use Board (SLUB) in preventing indiscriminate diversion of good agriculture, scientific management of land use and conservation.

Crop Season
 Crop  seasons in India are broadly divided into two — 
 (i) Kharif or the summer/rainy season, in which crops requiring more water are grown; 
 (ii) Rabi or winter season in which crops requiring less water are grown. The periodicity of the season usually allows two and in few cases three harvests in a year.
 Kharif Crops — These crops, which require much water and a long hot weather for their growth, are sown (in June or early July) with the commencement of southwest monsoon and are harvested by the end of monsoon or autumn (September/October). The main kharif crops include rice, jowar, maize, cotton, groundnut, jute, hemp, tobacco, bajra, sugarcane, pulses, forage grasses, green vegetables, chillies, groundnuts, lady's finger etc.
 Rabi Crops — These crops, grown in winter, require relatively cool climate during growth and warm climate during germination of their seeds and maturation. Therefore sowing is done in November and crops are harvested in April-May. The major rabi crops are wheat, gram and oilseeds like mustard and rape seed.
 Zaid Crops — Besides these two dominant crops, a brief cropping season has been lately introduced in India mainly in irrigated areas where early-maturing crops, called zaid crops, are grown between March and June. The chief zaid crops are urad, moong, melons, water melons, cucumber, tuber vegetables etc.

Cropping Pattern
 'Cropping Pattern' is the relative proportion of cropped area under various crops in different parts of the country at a particular period of time. The choice of growing particular crop in a particular region depends on the following factors —
 (i) general agricultural conditions such as soil, climate, water supply, sub-soil water table, etc;
 (ii) aim of agricultural production, scale of production, size of holdings, techniques of agriculture, change in market prices, availability of transport and distance from market;
 (iii) personal factors like requirements for home and family consumption, meeting cash requirements of family, meeting feed and fodder needs of the year, for maintaining soil fertility or for green manuring, seed purposes etc.

 

Some of the characteristic features of cropping pattern in India are —
 (i) Amazing variety of crops — In Eastern India, east  of 800 east longitude and in the coastal lowlands, specially the western cost, south of Goa, rice is the predominant crop. Tea and jute are the major crops of East India. West of 800 east longitude and north of Surat (where rainfall is below 100 cm) jowar, bajra, pulses, cotton and groundnut are the chief crops in the plateau; and wheat including pulses, gram, cotton, oilseeds, jowar, bajra and in irrigated areas sugarcane are all grown in the alluvial plains of Uttar Pradesh,
 Punjab and Haryana.
 (ii) Preponderance of food over non-food crops — About three-fourths  of the total cropped area is under food crops. Among the food crops the chief crops grown are rice, wheat and millets with some maize and barley, occupying about 70 percent of net sown area. Pulses come next in area followed by oilseeds. Substantial area also lies under tobacco, potatoes, fruits and vegetables, tea, coffee, rubber and coconut but their share in total cropped area is relatively small.
 The stone fruits, apricots, peaches, grapes, melons are found in the north in mountain and uplands.

Intensity of Cropping
 One of the methods to increase the total food production is to increase the net cropped area. However, after a certain limit it is impossible to increase the net cropped area. Therefore the only way left to increase the total food production is to increase the intensity of cropping and crop yields.
 Intensity of cropping means growing a number of crops on a field in one agricultural year. Suppose a farmer has 5 hectares of cultivable land on which he grows a crop during the kharif season. After harvesting the kharif crop he again grows a crop during rabi season on the same land but on 2 hectares area only. This means the farmer obtained the crops from a total of 7 hectares area (from 5 hectares are during kharif  and from 2 hectares area during rabi season) though in fact he had only 5 hectares of land. Had he sown only one crop during kharif season on the 5 hectare land then the index of cropping would have been 100 percent but in the aforementioned example index of cropping will be 140 percent. Infact intensity of cropping reflects the efficiency of land use. The index of cropping is 126 percent for India as a whole but varies considerably with the states and districts. The index of cropping reached a maximum of 160 percent during 1983-84 in Punjab. It is minimum in the dry areas such as Maharashtra, Karnataka, Rajasthan and Gujarat varying between 115, 118, 116 and 109 percent respectively.
 The main factor that affect the intensity of cropping include irrigation, fertilisers, variety of seeds (early maturing and high yielding), selective mechanisation such as use of tractors, pumping sets and seed drills and plant protection using herbicide, pesticide and insecticide etc. Greater cropping intensity and increase in the proportion of area sown more than once have achieved stable and higher crop yields in many parts of the country.

Organic Farming
 Organic farming is natural farming which is based on the principles of no ploughing, no fertiliser or prepared compost, no weeding or tillage and no pest control but only sowing and harvesting and increasing the fertility of soil through biological residues. In its developed form it seeks to rely on biological processes to obtain high quality and yields which are often as good as those achieved using modern agricultural techniques.

Advantages of Organic Farming –
 (i) Reduced pollution;
 (ii) Less energy is used;
 (iii) Since no chemical pesticides, hormones and fertilisers are used, residues from these substance are no longer a danger;
 (iv) Less mechanisation is used;
 (v) Less occurrence of pest incidence due to absence of fertilisers and pesticides,
 (vi) Yields on par with modern farming;
 (vii) Food fetches more price than that produced from modern farming; and
 (viii) Is an excellent method of sustainable agriculture.

Problems of Organic Farming –
 (i) Land resources can move freely from organic farming to conventional farming but the movement is not free in the reverse direction;
 (ii) Loss of initial crop, while changing over to organic farming, particularly, if done quickly;
 (iii) Biological controls may have been weakened or destroyed by chemicals, which may take three to four years for residues to lose their effect;
 (iv) Farmers may be afraid to enter new system of farming without government support.

Significance of Organic Farming – The big challenge we are facing in agriculture today is the unsustainability of present (modern) system of agriculture. The nature and extent of the unsustainability of modern agriculture can be viewed considering the following consequences. Intensive cultivation of land without conservation of soil structure would lead ultimately to expansion of deserts. Irrigation without proper drainage would result in soils getting alkaline or saline. Indiscriminate use of pesticides, fungicide and herbicides could cause adverse changes in biological balance as well as lead to an increase in incidence of cancer and other diseases through toxic residues present in the grain or the edible parts. Unscientific tapping of underground water would lead to the rapid exhaustion of this resource left to us through ages of natural farming. The rapid replacement of a number of locally adapted varieties with one or two high yielding varieties in large contiguous area would result in spread of serious diseases capable of wiping out entire crops.
 The afore mentioned realities clearly indicate the significance of organic farming–the only way for sustainable agriculture–as the only alternative to unsustainable modern agriculture practice. Organic farming promises a better and balanced environment, better food and higher living standard to masses in India. It also promises better long-term future of agriculture, because of low-cost agricultural development.

Shifting Cultivation
 It is an agricultural system in which a patch of forest is cleared of trees and most vegetation, to be cultivated for few years until the fertility is seriously reduced. The site is then abandoned and a fresh site is cleared elsewhere. Cleared vegetation is usually burned (slash and burn) and crops planted in the fertile ashes.
 In India, variously known as jhum in Assam, ponam in Kerala, podu in Andhra Pradesh and Orissa, ewar, mashan, penda and Beera in different parts of Madhya Pradesh, shifting cultivation is practised by tribal people over an estimated area of about 54 lak hectares, about 20 lakh hectares being cleared by them (totalling more than 100 tribes) by felling and burning the forests every-year. Major crops grown are dry paddy, buck wheat, maize, small millets and sometimes even tobacco and sugarcane.
 Shifting cultivation is prevalent in the forest areas of Assam, Meghalaya, Nagaland, Manipur, Tripura, Mizoram, Arunachal Pradesh, Madhya Pradesh, Orissa and Andhra Pradesh. This way of exploiting rich forest soils is responsible for large scale removal of forests and soil erosion on hill slopes, and floods and the devastation due to them in the plains below. A check on this destruction of national wealth, therefore, is very essential. Considering the socio-economic aspect of this problem we must not only put a check on this type of cultivation but also educate the tribal people, who practise it, about improved methods of agriculture.

Dryland Farming
 Approximately 70 percent of the 141.73 million hectares of arable land in India, i.e. nearly 92 million hectares of land is rainfed and depends on natural precipitation, which is often erratic and unpredictable, for crop production. Even after total irrigation potential is realised by the close of the century (2000 A.D.) there will be nearly 50 percent of  the total arable land that will continue to be rainfed. Bulk of the crops like rice, jowar, bajra, other millets, pulses, oilseeds and cotton are grown in this area under rainfed conditions.
 Rainfed agriculture or dryland farming is solely dependent on rain water at any crop stage. It is synonymous with non-irrigated agriculture and refers to wide range of patterns from arid to humid conditions. Rainfed agriculture is of two types –
 (i)    Rainfed wetland farming is undertaken where rainfall is adequate and fairly well distributed during the crop season.
 (ii)    Rainfed dryland farming where agricultural activity is under low rainfall conditions which is erratic as well as concentrated in a short period. The water balance is frequently negative and moisture conservation is very essential here as compared to drainage of excess rainwater in the rainfed wetlands.
Problems of Dryland Farming – Rainfed agriculture is characterised by erratic and unpredictable rainfall. This results in wide fluctuations in production performance of crops in these areas. The soils of these areas are affected by erosion which results into poor moisture holding capacity besides impoverishment of soil in terms of nutrients. This makes the soil less productive and greater investment in terms of conservation and improvements.
 Wide variety of crops are grown in these areas which are directly dependent on availability of number of growing days. These are characterised by low production and low productivity.

Measures of Improve Production and Productivity
 Some of the improvements that have been introduced to increase the yield and production in the rainfed areas include soil and rainwater management; crop management; efficient cropping systems; and adoption of alternative land use systems such as the adoption of ecologically benign, economically viable, operationally feasible and socially acceptable cropping systems involving cultivation of high yielding predominant crops of different regions. Government has given high priority for the development of dryland areas and, therefore, several programmes and project have been launched for utilisation of potential of these areas for.
 (i)    Realising the project requirement of about 240 mt of annual food production by 2000 AD and to smoothen out fluctuation in annual production.
 (ii)   Reducing regional disparities between irrigated and vast rainfed areas;
 (iiii)  Restoring ecological balance by greening rainfed areas through appropriate mixture to trees, shrubs and grasses; and 
 (iv)    Generating employment for rural masses and reducing large-scale migration from rural areas to already congested cities and towns. Holistic approach for integrated farming system development on watershed basis in rainfed areas is the main plank of the development activities under the National Watershed Development project for Rainfed Areas (NWDPRA) initiated in the Eighth Plan.
 Arid Zone
 Arid zone are those regions which have very low annual rainfall, dry climate, high rate of evaporation and always have water deficiency.
 In India, arid regions are of two types : hot arid region and cold arid region.
 (i)    The hot arid region of India is spread over 31.7 million hectares–61% of it is in west Rajasthan and 20% in Gujarat, the rest being in Haryana, Punjab and Karnataka. The rainfall varies from 0-40 cm.
 (ii)    The cold arid region is spread over Ladakh in J & K. The rainfall varies from 0.2 - 4cm. The agricultural season in the region is limited to about five months a year due to high aridity and low temperature.
 In the hot arid zones the hot climate and shortage of water hampers agriculture. Only some drought resistant varieties of crops can be grown through cautious and scientific management of scarce ground water. Fruits like ber and pomegranate and fuelwood trees like acacia can be grown here. However animal husbandry involving sheep, goat, camel is best suited for this region.
 In the cold arid region the problem is same. Some cereals, oilseeds and fodder crops which mature in a short period and withstand severe cold can be cultivated. Yak and pashmina goats can be best reared in these regions.
