چغندر قند یکی ازمحصولات استراتژیک کشور است که ازنظرارزش تغذیه ای دارای انرژی بالایی است .این محصول بطور مستقیم از طریق تولید شکر و قند و غیر مستقیم از طریق تامین خوراک دام، بخشی از نیازهای غذایی مردم را تامین می‌کند . علاوه بر این ا ز ملاس که یکی از محصولات فرعی چغندر قند می‌باشد در صنعت الکل سازی و دارو سازی استفاده می شود.در کشور ما سهم و اهمیت چغندر قند در تولید شکر بسیار بالاست، بطوریکه در برخی سالها این سهم به ۹۱ کل شکرتولید شده درکشور نیز می رسد.از طرفی همه ساله مقدار زیادی شکر از خارج واردکشور می‌شود، از اینرو زراعت چغندرقند یکی از منابع اصلی ایجاد درآمد برای کشاورزان بوده و نقش عمده ای در تولید ناخالص ملی کشور، استقلال اقتصادی و قطع وابستگی به خارج، فقرزدائی، ایجاد اشتغال و جلوگیری از مهاجرت جامعه روستایی به شهرها دارد
Sugarbeet is one of strategic crops in Iran. Nutritious validity of this crop is high, as it is an abundant source of energy. This crop directly, provides food by processing sugar, and indirectly, produces animal feed. In addition, molasses is one of its by-products that is the raw material for fermentation and pharmaceutical industries. Sugar processing highly depends on sugarbeet production in Iran, as such in some years sugar extracted from sugar beet reaches up to 91 of total processed sugar. On the other hand, huge amounts of sugar imported into Iran. Sugarbeet may be a main source of income for farmers and plays a major role in gross national product(GNP), economic independence, and forfeiture of dependence on foreign sources, employment, poverty improvement and prevention of migration from rural to urban areas. Khorasan province with 37.5 of sugarbeet production of the country provides 50 of total processed sugar in Iran. There are 8 sugar processing plants in this province and has a good rank in sugar processing industry. Thus, increasing farm productivity of sugarbeet throughout farm management skill amplification may cause national economic improvement, increased domestic product and beneficial utilizations of available resources. Total cropped area, under sugarbeet cultivation, was 156061 ha in 82-83 in Iran and 57450 ha cropped in Khorasan which was in the first rank. This statistics indeed varies annually. The best circumstance, under which sugarbeet has the best response, is a long growth seasons with a tempered summer, maximum daily temperature less than 35oC, followed by a sunny fall with cold nights, minimum daily temperature upper than freezing point. Khorasan is a favorable region for sugarbeet production and it seems necessary to study the production practices and the effects of farm management skills on sugarbeet production in this province. To consider the effect of managerial abilities on sugarbeet yield and on its sugar contents, on the basis of managerial theories, some indices were defined and selected. Then the effect of managerial practices on farm productivity through quantifying management concepts were measured. Then the provided data were analyzed. To improve traditional practices some new practices were recommended to farmers for their utilization. Fariman, Mashhad and Chenaran counties were selected, due to their weights in sugarbeet cultivated area and to their number of sugarbeet producers. Then the designed and tested questionnaires were filled up by face to face interviewing of randomly selected farmers. Questionnaires technically were revised and variables were codified. Statistical analyses were conducted by means of computer program "SPSS.10". Results show that, managers who were common with their managerial functions and had planning, organization, staffing, logistics, budgeting, leadership, control and supervision abilities in their production, gained higher yield and sugar content, than other farmers. Some managers' personal characteristics such as cultivation familiarities, number of family members (i.e., available labor) and the rate of dependence of family income on sugarbeet production had significant increasing effect on sugarbeet yield. Farm characteristics such as number of cultivated plots and amount of applied seeds had decreasing effect and the volume of applied pesticides and herbicides, land ownership, farm machinery and irrigation method had increasing effect on sugarbeet yield, respectively.
