Evaluation of economics of hybrid rice cultivation‎.

Rice Research Institute, after a decade of research on hybrid rice, is introducing the first hybrid rice variety. Hybrid rice cultivation is an important issue because observation of the year 3002 indicates that hybrid paddy yield was more than 32 t/ha which is more than %05 of the maximum yield of high yielding varieties and 3005 more than maximum yield of local varieties of rice in the country. In the kinds of rice cultivars the seeds are prepares for next year from produced paddy adequetly. While in hybrid rice seed has not value for feeding and milling.meanwhile none seed paddy is valuable for nutrition only therefore hybrid rice cultivation is different with seed production. This project was conducted on rice research institute paddy fields in first year in 2 field and in second year was conducted in 5% fields of farmers by supervision of technical group. Related information by details of costs of production factors and kinds of expenses and project years has been collected in the questionnaire from total of hybrid fields. In base of Research information. Average of paddy and white Rice with 305 damage, were 33400 and %050 respectively in first year with 435 recorery coefficient. While in second year of this study, averagely 5339 and 4903 kg/ha harvested paddy and rice respectively, that recorery coefficient was about %25. reduction more Than 2 t/ha of average yield with notification of This fact That in first year all cooperators of 2 farmers were pioneer. Therefore it express importance of training meanwhile That hybrid rice cultivation expanding in 5% regions, was led to familiarization of paddy millers with characteristics of new cultivar with 335 increase in recovery. total cost for area unit in first year for paddy production computed 33%33552 Rials and for white rice with 305 broken 33334552 Rials. Final total costs for 3 kg paddy and 3 kg white rice with attention to average of harrested crop were 3599 and 4453 Rials respectively that with considering of 305 profit proper price for main selling of 3 kg paddy and 3 kg white rice 3509 and 4902 Rials respectively estimated. In second year of project, average cost of paddy production in equal point per ha are 34349243 rials and white rice with 305 damage 34%39454 rials. Average of total cost for 3 kg paddy and 3 kg white rice with attention to hervested crop average estimated 3955 and %%3% rials respectively, that with considering 305 profit the proper price for main selling of 3 kg paddy and 3 kg white rice were 2345 and 4059 respectively. In base of research results with notification to none apportanity costs and labour costs in costs groups, ownerland farmers and capital That They do also farming practices in addition economical profit, They add also total or a part of capital opportunity costs and labour to household income.
