abstract this study was conducted to determine the best drip irrigation method for pepper cultivation with the objective of water saving and obtaining maximum yield. the study was done during two years. experimental design was randomized complete blocks design (rcbd) in split plot with four replications. three different drip irrigation methods; drip irrigation with in-line emitter tubes, drip i...

introduction: nowadays, due to lack of water resources and increasing demand for water, agricultural water planning issues need further consideration. with proper planning and determination of irrigation depth and time, the effects of stress and yield loss on the plants are reduced. irrigation scheduling is one of the most important factors in crop’s quality and quantity. the main objective of ...

Water is a limited resource and the dramatically increasing world population requires a significant increase in food production. For improving both crop yield and water use efficiency, the usual optimization strategy in irrigation at the field level considers scheduling parameters, i.e. when and how much to irrigate, as well as control parameters, i.e. the intensity and the irrigation time, for...

With a population of more than six billion people, food production from agriculture must be raised to meet increasing demand. While irrigated agriculture provides 40% of the total food production, it represents 80% of the freshwater consumption worldwide. In summer and drought conditions, efficient management of scarce water resources becomes crucial. The majority of irrigation canals are manag...

Current climate change is projected to have significant effects on temperature and precipitation profiles, increasing the incidence and severity of drought. Drought is the single largest abiotic stress factor leading to reduced crop yields. Given the large share of water use in the agriculture sector and very low efficiency in this sector, selection and development of the new strategies to impr...

abstract due to limited water resources and occurrence of recent droughts, the use of new management and planning methods for optimal irrigation scheduling of agricultural crops is inevitable. present of appropriate mathematical and dynamic relationship between yield, evapotranspiration and water use efficiency parameters is the first and most important step in the optimal management of irrigat...

investigation of various irrigation methods and intercropping are effective strategies for increasing water use efficiency and improve crop production. a field experiment conducted to study the effects of alternate furrow irrigation on quantitative and qualitative characteristics of forage corn with annual alfalfa cropping under its canopy in ilam climate conditions. experiment carried out as a...

the objective of this research was to investigate the effects of deficit irrigation on physiological and agronomic terms of eggplant to maximize the water use efficiency (wue) without affecting the final yield and fruit quality parameters under arid environment. therefore, two field experiments were conducted at two different sites: ghor al-safi, jordan valley and sail al-karak, karak valley, ka...
