this research was designed to evaluate and compare the applicability of two different types of irrigation including traditionally (surface irrigation) and simple sub-surface drip irrigation (using pricked-pipe covered with plastic cloth). two plots containing 39 pistachio trees with 720 m2 area were selected in rafsanjan, iran. both plots were irrigated using exactly the same quantity and quali...

abstract shortage and improper distribution of rainfall in tea growing period are important growth limiting factors in tea fields in northern part of iran. if there is not any other limited factors, supplemental irrigation by sprinkler can increase tea yield. this study was carried out in order to investigate the optimum sprinkler irrigation interval on yield and water use efficiency of tea. th...
