Abstract

To realize the current state of mechanization, defined and meaningful indices and standards are needed. Evaluation of these indices can be used for correct estimation and optimal use of agricultural machines. In this study, by collecting data through questionnaires and available statistical sources, the indices determining the status of rice mechanization (including the degree, level and capacity of mechanization, executive level), working days and farm productivity were calculated. The number of agricultural machines needed to perform mechanized operations in different stages of rice production were estimated using the time opportunity method. The results showed that in the eastern and western regions the degree of mechanization was 74.8 and 66.9%, the level of mechanization was 3.95 and 3.54 horsepower per hectare, the average mechanization capacity was 390.48 and 391.80 horsepower per hectare, respectively. Also, there were a tractor for every 29 and 27 hectares, a tiller for 3 and 4 hectares, a transplanter for 29 and 25 hectares, a weeder for 81 and 189 hectares, and a combine for every 39 and 77 hectares, on average. The number of machines available in the eastern regions in tillage are 81.5%, Transplanting 2.5%, spraying 71%, and harvesting 38.5% more and in weeding 9% less than the estimated number. the number of machines available in the western regions in tillage are 80.6%, Transplanting 15.9%, spraying 70.8%, weeding 42.3% and harvesting 51.5 % more than the estimated number.
