Abstract: The aim of the article is to search the influence of the size using area on the labor productivity in fertilization of field crops. The labor productivity in our agriculture and the competitivеness of agricultural products are lower than the other EU countries. The labor productivity in the agriculture is about three times smaller than the other sectors of the national economy and 12% of the average for EU-25. One of the main reasons for small labor productivity in the agricultural sector of Bulgaria is a low supply with agricultural machinery, as well as its technical status and effective use. Many factors influence on the effective use of agricultural machinery, including the size of using area. The size of using area of agricultural farms varies in large limits. In the study are calculated the theoretical coefficient of utilization of the working time and the labor productivity at lengths of working field 100, 200, 300, 400, 500, 600, 700, 800, 900, 1000m and the allowable minimum-maximum working speed for of the mass used tractors and fertilizing machines. There is substantial increase of the labor productivity at the merging fertilization of field crops until 400m length of land area (34%), from 400 to 700m - until 12%, out 700m until 7%. The increasing of the labor productivity at the line fertilization of field crops is the most until 500m length of land area (192%) from 500 to 700m - until 12%, and out 700m 9%. The results show that farmers have to analyze the size of own land area before to decide whether to bay the technical equipment, as well as leasing and association with other farmers.
