In order to determine the genotypical differences and basic selection parameters for salt tolerance 36 melon genotypes were grown in hydroponics culture. When seedlings reached to 4-5 leaf stages 150 mM NaCl was applied to them. 14 days after salt application, young plants were harvested from control and salt treated groups. The fresh weight of green parts of young plants and the amount of some...

Low nutrient and high pH of circulating water represent two the main issues to overcome for a successful combination aquaculture hydroponics in aquaponics offering sustainable circular economy solution vegetable production. The purpose this study was screen tolerance four herbs low concentration hydroponics, i.e., green red basils, mint, rocket salad, with focus on plant yield nutraceutical asp...

Forage plants introduced to Hawai`i have come from both temperate and tropical areas of the world. Although introduced species have changed the face of the landscape, they have often failed to provide long-term benefits to the livestock industry. Proper management of rangelands can result in increased livestock productivity and reduce the need for further introductions of forage plants. Almost ...

Root system architecture (RSA) plays an important role in the acquisition of both nitrogen (N) and phosphorus (P) from the environment. Currently RSA is rarely considered as criteria for selection to improve nutrient uptake efficiency in crop breeding. Under field conditions roots can be greatly influenced by uncontrolled environment factors. Therefore, it is necessary to develop fast selection...

Growing greenhouse vegetables is one of the most exacting and intense forms of all agricultural enterprises. In combination with greenhouses, hydroponics is becoming increasingly popular, especially in the United States, Canada, western Europe, and Japan. It is high technology and capital intensive. It is highly productive, conservative of water and land and protective of the environment. For p...

George Mason University’s hydroponic greenhouse and the Patriot Green Fund requested an irrigation data logging system to track how weather conditions affect frequency at which plants need be watered. A prototype was created tested in greenhouse. The initial found have significant issues brought back lab for modification. Upon testing lab, it that sensors had multiple issues; further is require...

Cattle 's grazing of the locoweed Wahweap milkvetch (Astragalus lentiginosus var. wabweapensis) was evaluated on desert and foothill winter range during the winter of 1986 to 1987. Dry, dead stalks of Wahweap milkvetch that had grown in 1985 and 1986 made up 15% of cattle diets overall, and 24% of diets when cattle grazed gravelly benches where it was abundant. Nutrit ional quality of Wahweap m...
