Role of Irrigation in Different Operating Systems in Iranian Tea Growing Areas

In tea cultivation areas¡ irrigation¡ adapting new irrigation systems¡ small and distributed lands¡ low technical knowledge¡ high cost of production¡ low yield and low income of tea farmers reflects the effect of production system in the country. In this research¡ to achieve a proper production pattern regarding irrigation aspect¡ practical investigation of production systems in tea growing regions was conducted. In this project two methods of library and field research were used. Style of sampling was cluster randomly using the Kokran formulae to find out volume and number in the society. By filling the questionnaire¡ relation between irrigation as independent variant and yield as dependent variant in different production systems were investigated. Then¡ data were analyzed with using of descriptive and inference statistics (Tuki test). In all three systems¡ irrigated gardens got more yield. Out of three identified systems in tea growing regions (rural¡ common cooperative and commercial)¡ the maximum yield was belong to the common cooperative system regarding the mentioned variable.
