p omegranate is one of the most important economic products in the agricultural sector in Sistan region. This region due to dry weather, very low rainfall and frequent droughts and lack of resources for agriculture faces many problems. Hence, one way to increase agricultural production is to increase efficiency, So that it can help the economy of the region. In this regard, in this study, ...

The development of catchment modelling tools has gained considerable momentum through the Cooperative Research Centre for Catchment Hydrology’s Catchment Modelling Toolkit. This repository of models (see www.toolkit.net.au) allows the modeller to select the most appropriate tools with which to best represent their catchment and associated constituent processes. While this has improved the abili...

One of the obstacles that has caused agricultural sector not to reach significant and expected growth is shortage of short, medium and long–term funds to finance various activities of this sector. This study aims at investigating the economic impacts of credits granted by Agricultural bank on farmers on Hirmand region. The statistical population of the survey included 4691 farmers of Hirmand re...

Water quality data, collected by the Environment Agency in England and Wales over 10 years (1991 – 2000) were used to examine the spatial distribution of nutrient pollution risk and for assessing broad-scale spatial and temporal variability in nutrient fluxes across the Wye catchment. Nutrient water quality across the upper and middle Wye catchment, and along the main River Wye, is generally ve...

Recently, great emphasis has been placed on using soilless media in greenhouse culture for evaluation of plant nutritional efficiency. A factorial experiment, in a completely randomized design with three replications, was conducted to categorize wheat genotypes according to their Zn acquisition efficiency (ZACE) and Zn utilization efficiency (ZUTE). To study the Zn acquisition and utilization e...

A new approach to regionalisation for prediction of flow characteristics in ungauged catchments is presented. If flows in ungauged catchments are to be predicted using calibrated rainfall-runoff models, regional relationships between the parameters of such models and catchment attributes must be determined. This is only possible with parsimonious models (fewer than about 7 parameters), and even...
