A more efficient water use system is needed for agriculture. This is more evidence for rice production with a higher water use for economical production. A large cultivar×water regime interaction exists for grain yield in rice. Therefore, information is required to adopt new rice cultivars with high yield potential under water-saving conditions. The objectives of this study were to analyze the ...

at the research farm of vali-e-asr university of rafsanjan in 2013. the experiment was arranged in a randomized complete block design with four replications and four irrigation intervals. irrigation was done after 40 (control), 60, 80 and 100 mm evaporation from pan class a, from seedling establishment till physiological maturity. results showed that irrigation level did not significantly chang...

Spatial characterization of soil physical properties could improve the estimation of surface irrigation performance. The aim of this research was to characterize the spatial and time variability of a set of irrigation related soil properties. The small-scale experimental level-basin (729 m) was located on an alluvial loam soil. A corn crop was established in the basin and irrigated five times d...

Humic substances (HS) reportedly enhance moisture retention of soil. However, no information is available as to the effects of HS on sand-based golf course putting greens. HS have acidic functional groups (COOH) that are reaction sites on the molecule. An greenhouse experiment was conducted to evaluate the effect that the acidic functional groups in humic acid, tannic acid and citric acid have ...

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...

INTRODUCTION The aim of this study was to compare the efficiency of a sonic device (Vibringe), syringe irrigation, and passive ultrasonic irrigation in the removal of debris from simulated root canal irregularities. METHODS Root canals with 2 standardized grooves in the apical and coronal parts were filled with dentin debris. Three different irrigation procedures were performed with NaOCl (1%...

Septic arthritis of the knee is encountered on a regular basis by orthopedists and nonorthopedists. No established therapeutic algorithm exists for septic arthritis of the knee, and there is much variability in management. This study assessed the number of surgical procedures, arthroscopic or open, required to eradicate infection. The study was a retrospective analysis of 79 patients who were t...

one of the biggest barriers for agricultural production in iran is water deficit. however, certain optimum approaches for water application can solve this problem. deficit irrigation technique is an approach that could have a better and economic use of water in agriculture. in this regard, a research with three factors including two irrigation intervals of 8 and 12 days, two nitrogen fertilizer...
