This report investigates the costs and benefits associated with the conversion from semi-enclosed seep irrigation to either automated seep or automated sub-drip irrigation for potato production in Northeast Florida. These costs and benefits are estimated at the level of the individual grower and for the public at large. The analytical tools in the report include financial budgeting and regressi...
This study aims to evaluate the present management of border irrigation systems applied to wheat, alfalfa and sugar-beet farms in Boyer-Ahmad and Gachsaran cities in Kohgiloyeh and Boyer-Ahmad Province. Experimental farms included 8 alfalfa farms, 5 wheat farms and 5 sugar-beet farms. The experiments were conducted at different growth stages of plants and customary borders with prevalent dimens...

It increases need water production conditions to meet increasing demand. Irrigation methods irrigation systems are needed water. As a matter fact, which method or system is chosen study researches cost calculations. In this study, comparative economic analysis ...
To meet the challenge of a limited and costly water supply, South African sugarcane growers will have to find ways of increasing the efficiency of irrigation to maintain high cane and sucrose yields. The term ‘water use efficiency’ (WUE) is generally used as a measure of the overall effectiveness of water (either rainfall or irrigation, or both) for crop production. WUE can be defined as cane y...
Today, one of the biggest challenges facing the world is the lack of water, especially in the agricultural sector. In this research, we investigated the effects of irrigation method and deficit irrigation with the urban refined effluent on biomass, grain yield, yield components and water use efficiency in single grain crosses 704 maize. This research was carried out in a randomized complete blo...
