although the physiological and morphological differences between intercropped species caused a higher wue possibly, most researches on multiple cropping systems have focused on yields and the resources use efficiency (water, light and nutrients) has been less investigated. in addition, optimal use of nitrogen is important to attain sustainable agriculture due to its role in wue improvement. the...
One of the main factors limiting the yield and productivity of irrigated rice in the Sahel of West Africa is the high cost of fertilizers and inefficient use of nutrients in the cropping systems. A two-year experiment was conducted over four consecutive seasons at Ndiaye (16°11’N, 16°15’W) and Fanaye (16°32’N, 15°11’W) along the Senegal River Valley to investigate alternative fertilizer managem...
The multiple cropping is the main agricultural production pattern, including double cropping of rice in south China and double cropping of wheat and corn in north China. Household investigation, typical farmland survey and county statistics inspection were performed to analyze the status and countermeasure of nitrate pollution in China. The result showed that the nitrate rate of underground wat...
the present study sought to investigate the role of dynamic assessment (da) in improvement of iranian efl writing performance at different language proficiency levels. to this end, after conducting the quick placement test, 60 iranian efl learners were assigned to two groups with different language proficiency levels. in both groups each participant wrote two compositions, one before and one af...
In this paper, we developed a more sophisticated method for detection and estimation of mixed paddy rice agriculture from Moderate Resolution Imaging Spectroradiometer (MODIS) satellite data. Previous research demonstrated thatMODIS data can be used tomap paddy rice fields and to distinguish rice from other crops at large, continental scaleswith combined Enhanced Vegetation Index (EVI) and Land...
To study the effect of fertilizer and planting pattern on chickpea and linseed plant traits in dryland farming, a field experiment was conducted in factorial layout based on randomized complete block design with three replications in Naqadeh, Iran during growing season of 2016-2017. Treatments were included six substitutive cropping patterns; sole cropping of chickpea, sole cropping of linseed,...
A field study was conducted at the Zabol Agricultural Research Center during the years (2003-2004) to investigate the effect of irrigation with treated municipal wastewater on the yield and quality of wheat and some soil properties. Irrigation treatments were: T1: Irrigation of wheat with well water during entire period of growing season T2: Irrigation of wheat with well water until the begging...
abstract poor reading comprehension can result in failure in using references, benefiting from professional gatherings and resources, keeping up with the growing body of knowledge in the virtual world of the internet, and failing to achieve in efl programs. the purpose of the present quasi-experimental study was to explore the effects of background knowledge and previewing narrative and expos...
The main goal of this research was to evaluate the potential HYDRUS-1D numerical model for estimating soil moisture (?) at different depths, actual crop evapotranspiration (ETa) and its components (crop transpiration, Ta evaporation, Ea) as well deep percolation (DP) irrigated winter wheat under water managements in semi-arid region Tensift-basin (central Morocco). simulations were performed da...
modeling of crop growth plays an important role in evaluation of drought impacts on rainfed yield, choosing an optimum sowing date, and managerial decision-makings. aquacrop model is a new crop model that developed by food and agriculture organization (fao), that is a model for simulation of crop yield based on “yield response to water“ with meteorological, crop, soli and management practices d...
