Historically, affordable machinery, which increased capability and standard of production and improved productivity, are key elements of agricultural mechanization. Transplanter machine in rice cultivation play such key role. The purpose of current descriptive-survey research was to identifying and analyzing advantages and barriers to use of transplanter machine in rice fields of Sari County. Statistical population consist of all the agricultural experts and agents (N=180) and rice cultivators (N=5560) in Sari County. By using Cochran formula 90 experts and 160 farmers selected as samples. Stratified sampling method with appropriate allocation within 2 sub-district and 14 villages was used to select farmers. The results showed that the two groups of respondents have consensus on advantages of the machine and emphasized on farmer healthy, reduced labor cost and saved time. In case of barriers, the results indicated that farmer highlighted economical barriers and expert emphasized on technical and educational barriers. The results of factor analysis for barriers revealed that the “technical-supportive barriers”, “economical barriers”, “extension-education barriers” and “socio-cultural barriers” explained 63.42% variance related to barriers to use of transplanter machine.

Agricultural sector as an important economic sector in Iran needs to tent and programming tend to potential advantage and susceptible role in food security. Attention to relative advantage in agricultural activity is one of the most important of programming aspects in this sector. So، in this article has been commutated relative advantage indicators for cultivate production in Sari in 2008-2009. The results indicated that among of production barley has no advantage and its DRC index was 2. 03، but its area harvested in the region was in third place. So، suggested to responder of the region make commitments of relative advantage of this production or replace a part of its area harvested by wheat or Canola. Also wheat at last of value exchange rate in Rials has DRC equal one that indicate high social profitable of this production even in the least social revenue persuasion producer to has the second place for area harvested in this province now.

In this study has been surveyed the effect of governmental supporting policies omission on optimal cultivate pattern of production in Sari in 2008-2009. In this article optimal implant pattern was determined with market and social benefits by using linear programming pattern. The results indicated that notwithstanding barely has no advantage according to social prices, but covered near 10000 hectare of the region that it must be mentioned. Also, by government supporting omission soybean and colza must be out from region’s pattern, increasing area harvested of wheat relates to market model in 30 percent and rice remain without change. So, it is suggested that amount of supporting from soybean and colza must have better programming till farmers get abilities for production and contest without government supporting

Efficiency survey of agricultural productivity is important and effective factor for increasing producer’s production and yield without extra costs. In this paper, technical, economic, allocative and scale efficiencies is estimated for Canola producer in Sari. It also has been estimated optimal amount of inputs for achieve to maximum efficiency. This article was on the base of Data Envelopment Analysis method and data for these analyses is collected by 161 questioners in 1387-88. The results indicated that mean of technical, allocative, economic and scale efficiency was 80/7, 58, 46/5, and 13/77 respectively. Maximum of undesirable use of inputs is related to pesticides with inefficiency 49/39 percent. Minimum of it are related to seed and machinery. According to the results, by using programs that increase agricultural allocative efficiency such as expending terms to learn how must be used these inputs and government support can be increased production and decreased costs without changing technology level and amount of inputs usage.
