Extended Abstract
Introduction
Sugar beet (Beta Vulgaris. L.) is one of the industrial and strategic crops which accounts for a significant share of sugar production worldwide. Sugar is one of the imported goods and planning for sugar beet cultivation and sugar production is essential. Sugar beet cultivation and production are of great importance in the policies and plans of the Ministry of Agriculture Jihad due to its agricultural, economic and industrial benefits. Currently, the annual sugar consumption of the country is about 2-2.5 million tons and its annual sugar production is about 1.6 million tons. As a result, the country's deficit in sugar production is covered by imports. Therefore, obstacles to the production of this important product should be evaluated.
Materials and methods
In this study, the amount of rainfall recorded at the Kiyar meteorological station, Chaharmahal and Bakhtiari province, and also the data of Hafshejan sugar factory including cultivated area as well as root yield and sugar yield in the basin of Kiyar in the period 2012-2020 were evaluated. The obstacles of sugar beet cultivation were then examined. The data collection tool was a questionnaire and the statistical population consisted of 480 growers. The sample size was determined by simple random sampling using the Morgan method, which resulted in 215 growers. Descriptive statistics and inferential statistics methods were used to analyze the data. The descriptive statistics included population characteristics and statistical indices such as standard deviation, median, minimum and maximum values of obstacles. In the inferential statistics, Pearson's correlation coefficient was calculated using SPSS (ver. 20) software. The Friedman test was used to rank the effect of each obstacle on sugar beet cultivation. Obstacles and difficulties in sugar beet cultivation were studied in seven factors: financial, economic, technical, social, motivational, climate, and supporting obstacles.
Results and discussion
The majority of participants in the survey were 40 years old and had diploma education. In the crop year The area under sugar beet cultivation was at its peak (606 ha) in 2016-17 and decreased significantly since then in Kiyar county. Average scores of financial (78.41), motivation (65.23) and support barriers (56.38) were less than their median (79.26, 66.38 and 57.72, respectively). The Friedman test achieved the highest score for technical obstacles with average of 6.59 followed by two factors, economic and financial obstacles with average score of 5.44 and 4.52. The correlation between sugar beet cultivation and financial, economic, technical and motivational obstacles was positive and significant at 1% probability level (0.74, 0.74, 0.86 and 0.72, respectively) and with social, climatic and supportive obstacles was positive and significant at 5% probability (0.62, 0.51 and 0.61, respectively).
Conclusion
In order to increase the su gar beet cultivation and sugar production, the above-mentioned obstacles should be considered. Providing financial credits, improving technologies, increasing technical training and effective government intervention in pricing processes are some of the appropriate strategies to overcome these obstacles.
