abstract to study the effect of water stress in rapeseed cultivars at the seedling stage, 10 rapeseed cultivars were evaluated at three irrigation levels [normal irrigation (control) and irrigation after depletion of 60 and 85% of available soil water]. analysis of variance showed considerable variation among cultivars. water stress reduced all of the studied morphological characteristics, espe...

A ®eld experiment was conducted during the dry season of 1993/1994 at the Irrigation Research Farm, Institute for Agricultural Research, Samaru, Nigeria to evaluate water management options on the performance of tomato. The trial involved three furrow irrigation methods (conventional furrow, conventional furrow with cutback, and alternate furrow), two mulch treatments (without mulch and straw m...

This research was carried out to evaluate the effect of drought stress on grain yield and qualitative traits in some Iranian landraces of confectionary sunflower. Fifty six confectionary sunflower landraces were evaluated using three different water treatment conditions with three separate rectangular 7 × 8 lattice design with two replications. Irrigation treatments were as follows optimum irri...

this study was conducted to analyze the effect of zeolite application on yield and yield components of rapeseed under drought conditions as a factorial-split on the based of randomized complete block design with four replications in 2011-12 in the research field of seed and plant improvement institute, karaj. the effects of zeolite levels z0 (0) and z10 (10 t/ha) under three drought stress leve...

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...

BACKGROUND Although most surgeons prefer to treat contaminated wounds as soon as possible, the effect of timing on the ability of irrigation to reduce the amount of bacteria in a wound is not fully known. We evaluated the effect of different delays in irrigation on bacterial removal in an animal model. METHODS A complex musculoskeletal wound was created in the proximal part of the leg of goat...

The extensive use of pesticides in agriculture is compromising soil and water quality. One major concern is protecting water resources from contamination. The main objective of this research was measuring 2,4- D in a silty clay soil and simulating temporal transportation of this herbicide in soil using a LEACHP model, in a corn root zone field. 2,4- D was applied at 3.5 kg a.i./ha, followed by ...

background & aim: aloe vera is used in the food and pharmaceutical as an aid to effective treatment. the purpose of this study is to improve growth, increase production of valuable metabolites and increase the sugars in aloe vera gel with low cost and high efficiency under water stress conditions. experimental: in this study, aloe vera potted in greenhouse conditions with four levels of zeo...

BACKGROUND One of the main causes of ventilator-associated pneumonia (VAP) is thought to be aspiration of oropharyngeal fluid containing pathogenic microorganisms. The aim of this study was to examine the effects of various oral care methods on the reduction of oral bacteria during intubation. METHODS First, the effect of mechanical oral cleaning was investigated. The bacterial count on the t...
