Response to the presentation of cultivated areas of the tomato crop in Iraq for the period (2015-198)

Abstract

The tomato crop is one of the main vegetable crops in Iraq and the most consumed, as it enters most of the cooked, fresh and canned foods. It is one of the most important vegetable crops economically and its nutritional and economic importance. It is grown in two winter seasons by covered agriculture , The study aimed at estimating the response of the presentation of cultivated areas with tomato yield using the joint integration tests and the error correction model (VECM) , The results indicated that the most important factors influencing the response to the presentation of the cultivated areas of the tomato crop are the area planted with the crop for the previous year, the previous year's crop price, the average summer vegetable price for the previous year, irrigation water, the Productive risk and the price risk) using the logarithmic formula , The results indicated a significant error correction at (5%) and a negative sign that is consistent with the economic theory and indicates a long-term equilibrium relationship in the model. The error correction coefficient (0.233185) indicates that the cultivated area of the crop takes about (4.3) Years in the direction of their equilibrium value after the impact of the shock in the model due to the change in explanatory variables , The study showed that the growth rates for area, production and productivity were positive(0.7 ,2.1 ,1.4) respectively
