From the late twentieth century, human kind has found out that if he wants to obtain cost efficiently and continuous utilization of lands, it is better to execute this in a planned framework named management plan. Such idea is became as an introduction to monitor the land or utilization of lands. Monitoring lands means contribution of an optimized space for land utilization with realization o...
with the increasing population and the need for more food, as well as with the development of science and technology, human approach to unnatural and often chemical inputs to increase agricultural production has been a great expansion and problems such as increased cancers, chronic diseases has created environmental pollution. implementation of organic organic is a solution to these problems . ...
This study was carried out to evaluate drought stress tolerance in Thymus kotschyanus accessions using a factorial experiment based on a Completely Randomized Design (CRD) with 5 replications during 2013-2014 in Qom, Iran. The first factor was the accession with 17 levels and the second factor was drought stress with three levels of irrigation including 80% (control), 60% and 40% Field Capacity...
In this experiment the effect of inoculation with Azospirillum on the flag leaf and spike rachis anatomical features and also on grain yield and grain weight was investigated for the first time in bread and durum wheats during 2015-2016 growing season under semi-arid condition. The crop yield increased due to the inoculation with Azospirillum with a maximum yield increase of about 8.0 per cent ...
Seasonal fallows – periods with no living plant cover are frequently implemented in dryland cropping systems to allow recharge of soil moisture for the subsequent cash crop. Over time, repeated fallow deplete organic matter, a foundation health that affects long-term functional capacity soils. Reducing by growing crops (non-harvested terminated prior reproductive development), double (increasin...
In order to achieve a sustainable management of land resources and to improve land quality, quantitative assessment of effective factors and soil quality indicators are required. The aim of this study was to evaluate variability of selected soil quality attributes in central Zagros affected by such factors as region, land use and management practices. Twelve sites were selected in three provinc...
Soil enzyme activities are widely utilized as rapid and sensitive indicators in discriminating among soil management effects. The objective of the present study was to compare the influence of conservation tillage, i.e. direct drilling (DD) (residue cover is left on the soil surface) v. conventional tillage (CT), on soil chemical and biochemical properties in a crop rotation (cereals–sunflower–...
