The effects of soybean seeding rates on evapotranspiration (ETc) and grass- alfalfa-reference crop coefficients (Kco Kcr) were investigated under five (185,250, 247,000, 308,750, 370,500 432,250 seeds ha−1) (62, 82, 103, 124 144% the recommended rate 300,000 ha−1 in experimental region) different irrigation strategies (i.e. full treatment [FIT], limited 75% FIT 50% rainfed treatment). Kco Kcr v...

An approach for estimating human exposure to pesticides via consumption of six important food crops is presented that can be used to extend multimedia models applied in health risk and life cycle impact assessment. We first assessed the variation of model output (pesticide residues per kg applied) as a function of model input variables (substance, crop, and environmental properties) including t...

Hourly evapotranspiration (ET) crop coefficients (Kc) are needed to optimize the effectiveness and efficiency of high-frequency microand sprinkler irrigation practices involving the application of water multiple times a day. However, not much is known about the daily and seasonal patterns and magnitudes in hourly Kc values for soybean. In addition, locally developed Kc values are necessary for ...

sesame is one of the oldest crops in the world that is commonly cultivated in arid and semi-arid due to high oil seeds (42-52 %). this study was conducted to investigate the effects of sulfur and biological fertilizers on physiological parameters of sesame at sari agriculture sciences and natural resources university in 2014 crop year. the experiment was conducted in a split factorial design ba...

The present study aims at investigation of the performance of nanofibrous filter, containing magnesium oxide (MgO) nanoparticles, for bioaerosols removal from the air stream. It synthesizes two types of polyacrylonitrile (PAN) and PAN/MgO nanofibers via electrospinning technique, and investigates the antibacterial properties of the produced nanofibers through disk diffusion. The air containing ...

this research seeks to study the impact of pan-turkist ideology on central asia. the collapse of the soviet :union: and independence of the central asian and caucasian states once again revitalized hopes among the pan-turkist theoreticians and strategists who were hopeless about the implementation of their project of establishing a turkic empire in the southern parts of the soviet :union:. cons...

Crop coefficient values are used to estimate crop evapotranspiration (ETc) for determining irrigation scheduling. Many important crop biophysical properties such as Percentage Vegetation Cover and Leaf Area Index can be estimated from remotely sensed Vegetation Index, in order to quantify real time vegetation growth dynamics. The objective of this study was to understand the effectiveness of ba...

Leaf area index (LAI) and biomass are important indicators of crop development and the availability of this information during the growing season can support farmer decision making processes. This study demonstrates the applicability of RapidEye multi-spectral data for estimation of LAI and biomass of two crop types (corn and soybean) with different canopy structure, leaf structure and photosyn...
