استخدام التكنولوجيا الحديثة وأثرها في الإنتاج النباتي في ليبيا خلال الفترة (1990 -2014)

Abstract

The aim of this research is to study the impact of the technical change in the use of fertilizers, pesticides, harvesters and tractors in the crop yield of specific crops, namely wheat, barley, maize, fruits and vegetables in the period 1990 - 2014., and its impact on output quantities and productivity. The results for cereals showed an increase in production and an annual growth rate of 13%. Appreciating the impact of technical development on cereal crop production, it was found that growth was growing at an annual rate of about 1.3%. The assessment of the impact of technical development on production showed that it increased from about 1.46 thousand tons in 1991 to about 1.75 thousand tons in 2014 at an average annual rate of about 1.17 thousand tons, with a relative importance of 0.26% of the technical change occurring in fruit production and estimating the equation of exponential growth of production data, in the case, of stable productivity, and it turned out that the growth was stagnant and at an annual rate of about 1% on average.  The results also showed for vegetable production, that there was a decrease in the volume of production in general during the study period. In estimating the exponential growth equation of production data in the case of productivity stability.
