  Tomato Shading Study- Las Vegas 2018 Results Authored by Angela O Callaghan Cooperative Extension in southern Nevada has been recommending shading tomato plants in the summer to extend the season and help improve production as well as quality. The question remained “Does shading up tomatoes really help in such a harsh desert climate, and if so, how much shade? Do all tomato cultivars benefit equally?” This research aimed to obtain information that could be useful to small growers, including household growers, who must confront the in this region. We selected four commonly grown tomato cultivars: Celebrity, Early girl, Heat Wave and Red Cherry (a very small-fruited variety). The treatments were, 0%, 30% and 50% shade. We transplanted seedlings into raised beds with organically amended soils. The land where the raised beds were located where plants had not grown previously. Major problems included wind damage, sunscald, herbivory and root knot nematodes. The project had noticea...

  Tapping Soil Microbiota: Overlooked Underground Players in Agricultural Production Authored by Yuan Wang Soil, the base for agricultural production, is constantly influenced by a variety of physical, chemical, and biological factors. Despite the abundance and diversity, soil microorganisms have been largely overlooked until recent a few years, due to the untapped functions caused by the difficulties in microbe isolation and culture. Soil microbiota, by definition, is the microbial communities that reside in specific soil niches. With the advances of next-generation sequencing technologies, more and more soil microbiomes from different soil environments were dissected genetically and functionally. These studies suggest that manipulation of soil microbiota may be one of the potential solutions for next-generation agriculture.   To read more about this article:  https://irispublishers.com/wjass/fulltext/tapping-soil-microbiota-overlooked-underground-players-in-agricult...

  The Effect of Growing Season on the Nutrient Composition and in Vitro True Digestibility of Browse and Forb Species Commonly Consumed by Goats in the Southeastern United States Authored by Nar Gurung The goal of the study was to determine the nutritive values and in vitro true digestibility (IVTD) of browse and forb species consumed by goats at the Tuskegee University Atkins site. The site can be described as unmanaged long leaf pine plantation site approximately 10 years of age in the east, gulf coast region of Macon County, Alabama. The latitude of the Tuskegee site is 32.4230N and longitude is 85.6910W. The landscape is characterized by gently sloping topography (5–10 percent) and consist of many encroaching browse/forb species. The predominant grass cover is primarily of Andropogon virginicus (broom sedge) and other bunch grasses. These browse/forb species encompass much of the woodland vegetation in the Southeastern United States. Thirty different species were selected for a...
