Predicting of soil water characteristics curve with modified Van Genuchten model by particle size distribution data – JBES

soil waterBy: Samaneh Amanabadi

Abstract

Direct measurement of soil moisture characteristics curve (SMC) due to spatial and temporal variation is labor and expensive. So, prediction of SMC from basic soil properties which can be measured easily would be satisfactory. In this study, we use a dataset containing 18 UNSODA soil samples to evaluate the performance of modified Van Genuchten (VG) model. Continue reading

Estimation of Genetic Parameters for yield and its components in bread wheat (Triticum aestivum L.) genotypes under pedigree selection – IJAAR

Wheat,By: Kamal Hassan Ghallab

Abstract

Grain yield is a complex trait and is greatly influenced by various environmental conditions. A 3-year field investigation was carried out to estimate genetic parameters for yield and its related traits of wheat under selection in reclaimed soils conditions. Three field experiments were executed at the Experimental Farm of the Faculty of Agriculture, Fayoum University at Demo (new reclaimed sandy loam soil), Fayoum Governorate, during 2012/2013, 2013/2014, 2014/2015 growing seasons in randomized complete block design (RCBD) with three replications.

Determination of leaching efficiency coefficient in some saline and sodic soil in Khozestan province by using different leaching methods – JBES

yuma-desaltingBy: Zahra Behbahanizadeh Rezaian

Abstract

Salinization of arable lands is one important factor in decreasing crop yield and the osmotic potential of the soil. Recently, it is one of the big problems in developing countries. There are some various techniques to increase crop yield in saline soils such as amendment of soil area for plants. Leaching of soluble salts from soil profiles can be performed to solve this problem. In this study, three different leaching methods have been performed to estimate utilized leaching water in Veis region, Khoozestan, Iran. Continue reading

Effect of boiling and baking times on the functional properties of aerial yam (Dioscorea bulbifera) flours cv Dugu-won har vested in Côte d’Ivoire – IJAAR

Dioscorea bulbiferaBy: Gbocho Serge Elvis Ekissi

Abstract

The study examined the effect of boiling and baking times on the functional properties of aerial yam (Dioscorea bulbifera) flours in order to assess which one can ameliore better their functional properties. Boiling and baking times affected significantly (P<0.05) the functional properties of D. bulbifera cv Dugu-won flours. Continue reading

Lethal effects of tungsten and boric acid, and three garlic, basil and caraway essential oils on Amitermes vilis (Isoptera: termitidae) and its endosymbiont’s cellulolytic activity – JBES

Amitermes vilisBy: Sohrab Imani

Abstract

Termites are considered as one of the most important and largest groups of insects in terrestrial ecosystems that decompose lignocelluloses. Isolation and characterization of cellulolytic strains from termites will also provide information for understanding the efficient mechanism of lignin degradation in termites. In the present study, some termite specimens were collected from traps in “Khojir” Protected Area in Jajrud district of Pardis County, Tehran Province, Iran, and all were identified as Amitermes vilis. Five bacterial isolates in charge of decomposing celluloses were extracted from termite’s gut. Continue reading
