to study the effects of irrigation interval and nitrogen level on yield and yield components of fenugreek medicinal plant, an experiment in split plot arranged in randomized complete block design with three replications conducted at the azad university of birjand in 2009. treatments included; irrigation intervals (4, 8 and 12 day) as main plot and nitrogen fertilizer (none fertilizer, 50, 100 a...

The use of unmanned aerial vehicles (UAVs) for ecological research has grown rapidly in recent years, but few studies have assessed the disturbance impacts of these tools on focal subjects, particularly when observing easily disturbed species such as waterfowl. In this study we assessed the level of disturbance that a range of UAV shapes and sizes had on free-living, non-breeding waterfowl surv...

Herbal medicine is a clinical practice of utilizing medicinal plant derivatives for therapeutic purposes. It has an enduring history worldwide and plays a significant role in the fight against various diseases. Herbal drug combinations often exhibit synergistic therapeutic action compared with single-constituent dosage, and can also enhance the cytotoxicity induced by chemotherapeutic drugs. To...

Light is one of the most important environmental factors, acting on plants not only as the sole source of energy, but also as the source of external information, affecting their growth and development. Plants are empowered with an array of photoreceptors controlling diverse responses to light parameters, such as spectrum, intensity, direction, duration etc. These photoreceptors include the red ...

Fast and computationally less complex feature extraction for moving object detection using aerial images from unmanned aerial vehicles (UAVs) remains as an elusive goal in the field of computer vision research. The types of features used in current studies concerning moving object detection are typically chosen based on improving detection rate rather than on providing fast and computationally ...

Heteroconium schimae sp. nov. is described and illustrated occurring on dead branches of Schima superba. The specimen was collected from tropical forests in Fujian province of China. The type specimen is deposited in HSAUP (Herbarium of the Department of Plant Pathology, Shandong Agricultural University) and HMAS (Mycological Herbarium, Institute of Microbiology, Chinese Academy of Sciences).

high nitrogen and plant density cause increasing vegetative growth and reducing harvest index. the objective of this study was to evaluate the effect of cycocel at high nitrogen and plant density on safflower yield and yield components. for this purpose a field experiment was carried out as a factorial-split plot based on randomized complete block design with three replications with esfahan 14 ...
