Experiment was conducted as split plot in a randomized complete block design with three replications in Kermanshah to shed lights on economic analysis of deficit irrigation and integrated application of biological and chemical fertilizer son cultivation of medicinal plant Borage (Borago officinalis L). Irrigation tritments include: a) 30% less water than crop requires invegetative, b) inreprodu...
drought is common across the south of iran, especially in darab district. accordingly, studying the economic aspects of deficit irrigation technique – that is one of the basic strategies in water saving for reducing water use of cotton as one of the main agricultural products in darab district is essential. in order to investigate the deficit irrigation technique and to determine its economic t...
management of chemical fertilizers application is very important issues on environment and plant yield especially in arid and-semi arid region. in order to determine the effects of drought stresses and fertilizer levels on quantity and quality yields of psyllium (plantago ovata l.), a study was conducted as split plot based on randomized complete block design with four replications at the natur...
Using plants for the remediation of soils contaminated with heavy metals is an economical, cheap, and effective strategy. The goal of this research was to study the effect of sewage sludge and drought stress on the remediation of cadmium in soil, root uptake by corn plant. This study was carried out on corn in factorial design experiment based on completely randomized design with three replicat...
Regarding the insufficient water resources, developing of cultivars with high tolerance to water deficit can be very effective to optimize water consumption. To identify maize hybrids with higher tolerance to water deficit, 52 single cross hybrids were field evaluated according to a randomized complete block design with three replications in each irrigation regime. The hybrids were produced thr...
Biofertilizers included solid, liquid or semi-solid materials that contain one or several microorganism species developing plants root system leads to better uptake of water and nutrients resulting in the further growth of the plant. To evaluate the accumulation of nutrients in leaf and biomass production of pot marigold (Calendula officinalis L.), a factorial experiment was conducted based on ...
Application of the modern irrigation systems such as T-Tape irrigation system is one of the ways to achieve aptimal irrigation The present study deals with the effect of surface and subsurface drip irrigation systems on the cotton yield For this purpose, a field experiment was conducted in the Agricultural and Natural Resource Research Institute of Orzoueyeh, located in the Kerman province. The...
In order to study the effects of foliar application of phosphorus (P) and water deficit on yield and yield components of winter wheat (Triticum aestivum L., cv. Alvand), a split-plot experiment, with completely randomized blocks design and three replications, was carried out at the Research Farm of Boyer Ahmad Agricultural and Natural Resources Research Station, 13 km west of Yasouj, in 2008-20...
Considering water scarcity in Iran, application of deficit irrigation or water stress on some crops is inevitable. We need to provide appropriate design for deficit irrigation. Furrow irrigation management to obtain high efficiency and uniformity is difficult. Therefore, to investigate the variation of the input discharge, the cut-off time and furrow length that are effective on the efficiency ...
Sesame (Sesamum indicum L.) is one of the most important oilseed crops in the world. Drought stress is one of the environmental factors limiting sesame production. The effects of water deficiency can be reduced by inoculation of plant roots with mycorrhiza fungi. In this experiment, the objective was to determine the effects of different levels of water application (60, 80 and 100% of soil mois...
