Agricultural productivity is a important aspect of agricultural geography. Agricultural productivity could be defined as the ratio of output to input in relation to land, capital and overall resources employed in agriculture. Irrigation is basic determinants of agriculture in arid and semi arid areas and where rainfall is inadequate. Irrigation means the supply of water to the land by means of channels, streams, and sprinklers in order to permit the growth of crops. Importance of irrigation has substantially increased after the enormous growth of population in developing and under developed countries. Irrigation is basic determinants of agriculture because its inadequacies are the most powerful constraints on increase of agricultural production. Therefore attempt is made here to assess the impact of irrigated area on agricultural productivity as irrigation is a determinants of agricultural productivity. The study is based on secondary data source. To examine the influence of irrigated area on agricultural productivity the Pearson’s Coefficient of Correlation, Coefficient of determination and regression analysis technique has been utilized. The study reveals that the increase of one percent net irrigated area causes for increase of value of composite index of agricultural productivity of tahsils of lower Sina basin by 0.632 in study region. |
