Role of Agriculture Sector in Economic Development of a Developing Country:

(2) Increase in Demand for Industrial Products:

When surplus is generated in agri. sector the purchasing power of the farmers will increase which will lead to increase the demand for industrial goods. In case of UDCs the market is limited as the incomes of farmers and the labor are limited. Therefore, the demand for manufactured goods remains limited. But when the agri. productivity increases the incomes of farmers etc., with increase leading to expand the demand for manufactured goods. In this way, the market will be extended. The manufactured sector will gain momentum. Moreover, in such, situation the demand for agri. inputs like fertilizers, tractors and harvesters will increase. This will also provide a stimulus to industrial sector. The expansion of industrial sector will have the effects on the means of transportation and communication. Following Prof. Harischman, so many forward and backwash effects will come into being. So many sectors of the economy will grow and producers profits will increase leading to enhance capital formation. This is the contribution of agri, sector to the other sectors of the economy when it trades with other sectors, according to Prof. Kuznets.

(3) Foreign Exchange Earnings:

The developing countries specialize in certain products which are to .be exported. As the production and productivity of these goods increases their exports increase. With this the foreign exchange earnings of such countries increase which can be utilized to import the capital goods. Such capital goods can be used for industrialization. In this way, the domestic use of raw material will increase leading to reduce the export surplus. But the domestic industrialization will become helpful in the production of import-substitutes. In this way, the foreign exchange could be saved. Thus, it is the agri. Development which results in foreign exchange earnings. The capital goods could be imported and industrialization process will be started. In this way, not only foreign exchange will be saved, but foreign exchange will also be earned when the manufactured exports increase. This is called 'Production Contribution' of agriculture sector, according to Prof Kuznets. As a result of this effect, in the first phase the production of the economy increases, while in the second phase the per capita output rises.

(4) Mobilization of Capital by State:

In the initial stage of economic development the capital accumulation can be made with the help of agri. surplus. As Prof. Johnson and Mellor Write:

"When the productivity increases in agri. sector, it means that either inputs are being used in lesser amount or agri. yields have been increased".

It is the labor which is the biggest input in the agri. sector which can be used for capital formation. If laborers are withdrawn from farms and they are utilized in the constructional fields the capital mobilization can be increased. Again capital mobilization from agri. sector can be made by imposing land tax, agri. income tax, educational and land cesses etc. But this is not possible because of political reasons. Thus when agri. sector contributes to other sectors of the economy and shifts resources to other sectors of the economy it is called Factor Contribution of agri. sector, according to Prof. Kuznets.

(5) Employment Opportunities:

It is the agri. sector which not only provides employment opportunities, but it also gives rise to diversification in such job opportunities. Whenever, the agri. productivity and incomes increase the demand in the rural sector increases. For example, the demands for small farmers, weavers, cobblers, carpenters, plumbers, masons, black smiths and machinists etc. will increase. In this way, the agri. development will promote the development of other sectors.
