Objective: Environmental and economic challenges resulting from the application of nitrogen fertilizers have increased Concerns about its productivity in the agricultural systems. Thus an experiment in order to investigate ability SSM-Wheat for simulation growth and yield of wheat (cultivar N-87-20) in response to fertilizer nitrogen in the direction decrease Pollution environm...

Surface soil moisture (SSM) is a major factor that affects crop growth. Combined microwave and optical data have been widely used to improve the accuracy of SSM retrievals. However, influence vegetation indices derived from red-edge spectral bands multi-spectral on retrieval has not sufficiently analyzed. In this study, we retrieved wheat-covered surfaces using Sentinel-1/2 data. First, modifie...

A robust crop model can assist in genetic improvement and cultural management of the crop. The objectives of this study were to describe a wheat (Triticum aestivum L.) model and to report results of its evaluation. The model simulates phenological development, leaf development and senescence, crop mass production and partitioning, plant nitrogen balance, yield formation and soil water and ...

This study investigated the effects of chemical treatments of salseed meal (SSM) on nutrient digestibility and digestive enzymes in colostomized hens and intact broilers. Finely ground SSM was treated (820 mL/ kg of SSM DM) with distilled water (pH 5.3), 0.67 M acetic acid (pH 2.4), or 0.67 M sodium hydrogen carbonate (pH 8.2), and incubated for 12 h at 37 degrees C. Five isonitrogenous and iso...

facing the issues with structural complexity about which stakeholders have different views, has increasingly led to the use of soft systems methodology (ssm) in solving managerial problems. moreover, the flaws of this methodology in the stages of modeling and feasible, desirable changes, have provided the motivation for applying cognitive map (cm) and system dynamics in the ssm modeling. presen...
