Article
Drought and high temperature are major environmental stress factors threatening wheat production during grain filling stage resulting in substantial yield losses. Four wheat genotypes (Suntop, IAW2013, Scout and 249) were planted under two temperature levels (25 and 30°C) and two water levels (15% and 25% soil moisture content). Wheat yield, leaf δ...
Article
The ability of plants to access water and nutrients is a key aspect of crop production and it is mainly through modified root growth that plants can optimize their access to those resources. Although genetics play a main role in shaping root traits, other factors such as soil physical characteristics and the distribution of water and nutrients in t...
Article
Break crops are used in agriculture to reduce soil pathogens and improve yield of subsequent cereal crops. However, they can also affect soil microbial communities beneficial to plant growth including arbuscular mycorrhizal fungi (AMF). Two wheat genotypes (IAW2013 and 249) were planted after crop rotation with canola or chickpea with different nit...

Background and aims Water and nitrogen are essential for plant growth and yield. Plants depend on surface roots for nutrient uptake, but frequently rely on deep root systems for water uptake, especially in semi-arid, rain fed crop production systems. Methods We used H218O and 15NH4+ tracers in pots to determine water and NH4+ uptake at depth by two...

Surface soil drying decreased both water and NH4+ Uptake at the top soil. However, increased water availability in deep soil layer increase water uptake but not NH4+ uptake. Water Water uptake could be improved by higher root length and greater proportion of intermediate diameter roots in the deeper soil layers. NH4+ uptake Could be improved by mor...

Slope and parent materials play critical roles in determining the soil erosion level. In this study the effects of slope position and parent material on soil properties of tea gardens were investigated in Lahijan, Guilan province, Iran. Four profiles on two different parent material based sites (i.e. granite and phyllite) were selected. Soils wer...
Conference Paper
Forest and pasture lands in highland of northern Iran are being extremely degraded and destructed because of extensive agricultural activities and tourism attractions, referring to a growth in the proportion of a population. These, therefore, land use changes are usually accompanied by reducing in concentrations of soil organic carbon and nutrients...
