increasing the efficiency of water use is one of the main topics of sustainable agriculture in arid and semi-arid. the use of some materials such as superabsorbent polymers increase water storage in the soil and thus reduces the water use. increase water storage in the soil to reduce the effects of drought and saline soil. in order to evaluate the effect of super absorbent polymer on survival a...

RESUMEN The present study was carried out in a Typic Hapludand soil in the municipality of ‘El Rosal’ (Colombia) and aimed to compare the yield performance of the cultivar Criolla Colombia under foliar applications of Zn chelate (0, 1, 2 and 3 kg ha) and edaphic applications of granulated Zn sulfated (0, 1, 2 and 3 kg ha). A split-plot, randomized complete block design, with four repetitions pe...

the superabsorbent polymer withholding water and disperse it gradually to roots increase soil water capacity. to study the effect of superabsorbent polymer on decreasing water stress effect as well as increasing irrigation efficiency a factorial experiment based on randomized block design with 4 replicates was design. treatments were 0, 10 and 20 % v superabsorbent and irrigation levels 25, 50 ...

INTRODUCTION Microorganisms are essential in the development of periradicular diseases and are the major causative factors associated with endodontic treatment failures. Microbial biofilms are communities of bacteria that attach to surfaces and form heterogeneous three-dimensional structures. The purpose of this study was to develop a biofilm model that closely mimicked in vivo biofilm and to d...

in order to study the effects of corn density and planting pattern for reducing herbicide application, an experiment was carried out in 2007 at varamin research station of plant protection research institute. the experimental design was a randomized complete block in a split plot arrangement with 4 replications. experimental factors consisted of planting patterns at 4 levels included one row pl...

Topical hyaluronic acid (HA) is routinely used in the local treatment of chronic wounds, but few data have been reported to date. A 60-day double-blind, randomised, controlled superiority trial was designed to investigate the efficacy and safety of a gauze pad containing HA in local treatment of venous leg ulcers, compared with its neutral vehicle. The primary endpoint was the percentage of wou...

On-farm activities that reduce GHG emissions or sequester carbon from the atmosphere to compensate for anthropogenic emissions are currently being evaluated by the Australian Government as carbon offset opportunities. The aim of this study was to examine the implications of establishing and grazing Kikuyu pastures, integrated as part of a mixed Merino sheep and cropping system, as a carbon offs...

Two cross-linkers with different functional groups amide (N,NMethylenebisacrylamide (NMBA)) and esters (Ethylene Glycol Dimethylacrylate (EGDMA)) have been selected for comparative study for crosslinking polyaspartic acid (PAsp) and acrylic acid (AA). Thus, resulting in formation of different polymers with PAsp and acrylic acid in different ratios and cross-linked with different cross-linkers. ...
