Nowadays, the root characteristics as one of secondary traits along with grain yield are used to response evaluation of rice genotypes under deficit irrigation. Thus, to evaluate the root traits of 40 irrigated rice genotypes to water limited condition a pot experiment was performed in 2014 at Rice Research Institute (Rasht), Iran. Irrigation treatment was applied in two levels include con...
Water is essential for life. Specifically in the oases of inland arid basins, water is a critically limited resource, essential for the development of the socio-economy and the sustainability of eco-environmental systems. Due to the unique hydrological regime present in arid oases, a moderate groundwater table is the goal of sustainable water management. A shallow water table induces serious se...
in this study, the effect of furrow firming rollers were investigated to improve furrow irrigation parameters such as: advance time, runoff, deep percolation and irrigation efficiency (application efficiency) in the roller treatments, nonroller treatments (traditional) and treatment of including compacted with tractor wheel in the miandab agriculctural station in west azerbaijan during 2001-200...
In order to study the relationship between grain filling rate, duration and leaf relative water content (RWC) and yield, an experiment was conducted at Rice Research Institute of Iran, as a randomized block design in Split Plot with 3 replications, in 2006. 5 irrigation levels as main factor (Continuously flooded, days after water banishment, 5, 8 and 11 day intervals immediately after 10 days ...
In Africa, malaria is predominantly a rural disease where agriculture forms the backbone of the economy. Various agro-ecosystems and crop production systems have an impact on mosquito productivity, and hence malaria transmission intensity. This study was carried out to determine spatial and temporal variations in anopheline mosquito population and malaria transmission intensity in five villages...
Institutionalization of Water Users’ Cooperatives (WUAS) is one of the strategies for cooperative irrigation management, which lays the foundation for the participation of farmers in tackling water shortage challenge to reach the objectives of sustainable management of agricultural water in an efficient manner. The main purpose of the present study was to identify the grounds for improving WUAs...
One of the main problems in the management of large water supply and distribution systems is the forecasting of daily demand in order to schedule pumping effort and minimize costs. This paper examines a methodology for consumer demand modeling and prediction in a real-time environment of an irrigation water distribution system. The approach is based on Adaptive Neuro-Fuzzy Inferences System (AN...
rejection of pressurized irrigation by farmers is the problem in the agricultural sector in the north of the khouzestan province. as the statistics show, only five percent of the farmers used to do this type of irrigation systems. therefore, in this study by using field study and logit model, causes of rejecting pressurized irrigation methods in three townships shosh. andymeshk and dezful have ...
