In this study, the optimum irrigation depths for corn grain production under different conditions, i.e. maximum grain yield production and maximum benefit under limited land and water conditions, were determined under sprinkler irrigation in Bajgah (15 km. north of Shiraz). The results showed that, the optimum depth of irrigation for maximum grain yield production was 77.0 cm. Because of low pr...
Irrigation water management plays a crucial role in the growth and prosperity of countries like India. Optimization Techniques can be effectively used in the management of irrigation water. Motivated by a real crisis in Andhra Pradesh, India, the authors made an attempt to provide scientific solution to the problem of management of Pennar Delta System of Nellore District in Andhra Pradesh. The ...
investigation of physiological responses to water deficit in sesame (sesamum indicum l.) genotypes can help to identify effective mechanisms of plant resistance to stress. therefore, chlorophyll content, proline, soluble carbohydrates, net photosynthesis rate, stomatal conductance, maximum quantum efficiency (fv/fm), plant height and shoot dry weight in a complete block factorial pot experiment...
Now days, turf management has encountered with water deficit, mostly due to low precipitation also industrial, agricultural and household demand and consumption. So, the objective of this project was to identify drought tolerance of warm and cool season turfgrass cultivars to different levels of regulated-deficit irrigation. The field experiment was set out in a split-plot based on completely r...
to evaluate the effects of fertilizing and deficit irrigation regimes on some chemical properties of soil and plant, an experiment was conducted during 2007 and 2008 growing seasons. experimental design was a split plot based on a randomized complete block design with four replications. the treatments consisted of three deficit irrigation regimes (main plots) and six soil fertilizing systems (s...
In Ardabil region potato crop needs several irrigation, however ground water supplies arebeing exhausted due to reduced precipitation and intensive irrigation. In this research droughttolerance of 10 commercial potato cultivars was studied at three irrigation treatments (100%,80% and 60% of required irrigation water) in Ardabil in a two years field study, 2013-2014.At harvest, marketable tuber ...
This research was carried out to study the effect of deficit irrigation and saline water on yield and yield components of maize (KSC-500) during different growth stages for Ahwaz climatic condition in the farming years 2010-2011. This research performed in three independent experiments according to a randomized complete block design with split plot layout in three levels of irrigation water and...
water scarcity in arid and semi-arid climate of iran has made deficit irrigation as a strategy for optimal water use and conservation in agricultural sector. this study aimed at evaluating the effects of water-deficit stress and n fertilizer levels on sugar beet performance. the study was conducted in split block design based on randomized complete block design arrangement. the row factor consi...
The use of indicators for sustainability evaluation is an important step towards operationalization of the concepts of sustainability and sustainable development. Many literatures on framework for sustainable water management consider any one dimension of sustainability. In this paper, the sustainability of an irrigation system is assessed from economic and environmental dimension. An optimizat...
this paper presents a comprehensive case study on electro-mechanical analysis of mems[1] variable capacitors. using the fundamental mechanical and electrical equations, static and dynamic behaviors of the device are studied. the analysis is done for three different modes, namely: dc (static mode), small signal ac and large signal regime. a complete set of equations defining dynamic behavior of ...
