There are many types of light source specifically bulbs in the market with different working principles. Each them provides intensity at wavelength. In order to check energy efficiency, it is not appropriate measure certain specific wavelength for same power rating bulb. Therefore, this paper reported averaging spectroscopy method measurement between 400-700 nm before comparison carried out. It...

in iran, onion plants are currently broadcast over the majority of onion fields and weeding and harvesting are done manually by seasonal workers. at harvest time, 40 worker-days are required to onion dig just one hectare. this cost could be saved if the operation could be carried out by machine. rear-mounted diggers can only be implemented if 40 cm spacing between rows is allowed for each tract...

Traditionally grown in soil, saffron cultivation has been plagued by limited arable land, variable climate conditions, and soil-borne diseases. Phenological studies of the crop during each its growth stages are crucial for mitigating detrimental consequences change, to which is extremely susceptible. These also help anticipating future farming systems that involve methods, irrigation, field, ma...

Lilium lancifolium is a plant resource used as both medicine and food because it enriched with polysaccharides, polyphenol compounds, saponins. Increasing the quality of species based largely on improvement using methods such selective breeding proper fertilization. In this study, we investigated different responses L. bulbs to treatment nitrogen (N) potassium (K) in Hoagland solution. A pot ex...
