dashte-mashhad reservoir provides the water supply needed for irrigating 120 acres of agricultural lands and also the soft water for people living in mashhad, chenaran, golbahar and a number of villages in the region. the deep wells of the region have been using the water stored in this reservoir since 1350 in a rate which exceeds that of water being imported to it, hence the decrement of the w...

  Background: Although borage ( Borago officinalis L.) is a valuable medicinal plant, no information is available on the responses of this plant to salinity. For this reason, it is necessary to determine responses of this plant to salinity .  Objective: Since germination and early growth stage is one of the most critical phases of plant life under salinity condition this experiment was conducte...

Mosquito larvae were collected in 3 provinces in Argentina and 1, in Uruguay, to search for pathogens which might serve as biocontrol agents. In all, 411 larvae belonging to 19 species were mounted and identified. They include 7 new province records for Argentina and a new country record for Uruguay. In Dec. 1984, three of us (JJB, EIH, JJG) collected mosquito larvae in the Provinces of Formosa...

Different methods to estimate electrical conductivity (EC) of saturated soil paste extract (ECe) 1:2 and 1:5 soil: water suspensions were evaluated. Soil samples taken from different depths (viz. 0-15, 15-30, 30-45, 45-60, 60-90 cm) the wheat field under irrigated saline regimes ranging 1.5 12 dSm-1. The relationship between soil-water suspension extracts (i.e., EC1:2 EC1:5) was established bes...

To determine salt sensitivity for wheat at various growth stages, a factorial experiment arranged as randomized complete block design was conducted in the ambient environment at the National Salinity Research Center, Yazd, Iran. Treatment were two cultivars of wheat (Kavir & Roshan) and salinity imposed at emergence, tillering, stem elongation, spike emergence and one week after anthesis. A con...

OBJECTIVES Recent studies of esophageal cancer (EC) and gastric cancer (GC) have been reported to have high incidence rates of these cancers in Golestan Province of Iran. The present study describes the geographical patterns of EC and GC incidence based on cancer registry data and display statistically significant regions within this province. METHODS In order to map the distribution of upper...

This study applied a non-parametric method to analyze the efficiency of farmers, discriminate efficient farmers from inefficient ones and to identify wasteful uses of energy in order to optimize the energy inputs for broiler production. Data were collected from 44 broiler farms in six villages in Yazd province (Iran) by using a face-to-face questionnaire performed in January– February 2010 peri...

BACKGROUND During the last decades, the number of dentistry units increased significantly across the country. The aim of this study was to assess the efficiency of dental units of Iran provinces regarding dental health inputs and outputs using Data Envelopment Analysis approach. METHODS In this applied descriptive-analytical study, the study population included all of Iran 31 provinces. The o...
