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 ...

Plastic mulch and drip irrigation are commonly used in high intensity vegetable production regions such as Florida. Drip irrigation can be much more efficient than sprinkler irrigation since only the root zone of the cropped area is irrigated. However, improper irrigation management can lead to wasted water and leaching of soluble chemicals such as nitrate. In this project, several irrigation t...

A field crop irrigation management decision-making system (CropIrri) was developed based on the soil water balance model, crop phenology model, root growth model, crop water production function, and irrigation management model. The irrigation plan is made through predicating of soil water content in root zone and daily crop water requirement using historical and forecasting weather data, measur...

abstract to evaluate the effects of the irrigation termination in different growth stages on yield and its components of autumn’s canola cultivars in isfahan region. an experiment was conducted in 2005-2006 in kabotar abad research station. a split plot layout within a randomized complete block design with tree replication was used. main plots were seven level of the irrigation cut-off time (d1...

Irrigation underpins agricultural productivity. The purpose of irrigation is to match water supply to crop water demand. The effectiveness of irrigation depends on the quality of the timing and duration of watering events, also called irrigation scheduling. Most farmers use heuristic rules to determine irrigation events. This often leads to over-watering which results in lower crop yields and w...

Irrigation systems are as old as man itself since agriculture is the foremost occupation of civilized humanity. To irrigate large areas of plants is an onerous job. In order to overcome this problem many irrigation scheduling techniques have been developed which are mainly based on monitoring the soil, crop and weather conditions. Irrigation scheduling engrosses when to irrigate and how much wa...

bitter asafetida (ferula assafoetida l.) is one of the medicinal-rangeland plants belonging to apiaceae family. the resin which is through incision secreted of the root has medicinal properties. the effect of rain on resin yield of this plant is one of problem of natural resources offices. the main aim of this study was to find out the effects of the irrigation on the resin yield, plants surviv...

Cooling during drilling Kirschner wires is not always effective in preventing thermal related damage. In this study, we used a human in vitro model and compared temperature elevation, insertion time, and extraction force between three Kirschner wire insertion methods-drilling with and without irrigation and pneumatic hammering. Forty five Kirschner wires were inserted into 15 fresh human cadave...

Irrigation is probably the most underrated procedure in Endodontic therapy. While most articles or presentations spend a great deal of time on shaping procedures, not much emphasis is given for irrigation. This has led to a great deal of confusion on the type of irrigant, the protocol and the method of use. The purpose of this article is to discuss root canal irrigants, irrigation techniques an...
