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...

in this study, the effects of long term use of urban wastewater (over 40 years) on soil salt content and related parameters were evaluated in the lands south of tehran. for this analysis, kriging methods were tested. according to the suitable model indices, ordinary kriging (ok) was suitable for ph, clay, na+, mg2+ and sodium adsorption ratio (sar) interpolation; log-normal kriging (log-normal ...

abstract to optimal use of available water, irrigation scheduling is important to over scarcity of water resources in arid and semi-arid area. in this research to estimate of maximum allowable deficit (or: management allowed depletion) and irrigation scheduling of fodder mays based on canopy-air temperature difference, a field study was conducted in agricultural faculty of karaj. the lower limi...

Crop production is a process of multiple inputs (water and nutrients, etc.), and the relationships between the inputs and crop yield are very complex. This study used a model for data envelopment analysis (DEA) to evaluate the efficiency of irrigation-fertilization schemes for winter wheat in North China. The field experiments were conducted at the Xiaohe Irrigation Experiment Station in Centra...

The effect of row spacings and irrigation levels on the earliness of seed production of cotton was investigated under the Mediterranean environment of central Greece. This particular cotton growing area is exposed to risk of autumn rainfall that might cause low seed quality in fields allocated primarily for seed production. Two varieties of cotton, Celia and Hersi, were planted in two row spaci...

An investigation was conducted to evaluate the water quality of some ground for irrigation, drinking and livestock consumption. Fifteen samples were collected from Babugonj upazila of Barisal district in Bangladesh. The chemical constituents of water samples were determined to find out their suitability for irrigation, drinking and Livestock consumption. As per pH all water samples were slightl...

BACKGROUND The need for reoperation or wound infection treatments between pulsatile and gravity irrigation are statistically equivalent, however, it is unclear which method maximizes operative efficiency and expeditious irrigation. In this study we set out to determine the differences in irrigation rate between these various treatment methods. METHODS This was an ex-vivo experimental laborato...

Water is a finite resource that must be shared among multiple users and economic and conservation objectives can often be seen as being in conflict. We explored this perception by conducting an integrated bioeconomic analysis of irrigated agriculture and the conservation of freshwater attributes in an agricultural landscape, the Tasmanian Midlands. We constructed a simple bioeconomic model base...

Napier grass is a perennial, tropical C-4 grass that can produce large amounts of forage. However, low temperatures and drought stress limit its productivity and nutritive value as a forage. To overcome these limitations, pearl millet × napier grass hybrids (PMN) were developed. It was hypothesized that PMN hybrids were more drought-tolerant, produced higher yields, and had higher nutritive val...
