Loss of biodiversity caused by impact of elephants (Loxodonta africana) on African woodlands may require a management response, but any action should be based on an understanding of why elephants choose to utilise trees destructively. Comprehension of elephant feeding behaviour requires consideration of the relative value of the plant groups they may potentially consume. Profitability of availa...

An experiment was carried out on weaned rabbits at Swine and Avian Research Program, Khumaltar from 11 June 2020 to July 29, after adjustment period of seven days. The objective evaluate the effect hydroponically grown forages growth performance rabbit. laid in completely randomized design with three treatments viz. control without inclusion hydroponic forage (T1), combination pea wheat (T2), c...

The effects of defoliation frequency (28, 35, 42 and 49 days) intensity (30, 40 50 cm above the ground) on green dry matter (GDM) yield, chemical composition Panicum maximum cv. Mombaça were evaluated under natural field conditions at Roraima´s savannas. Defoliation regimes affect productivity grass forage. decrease in pasture improved accumulation forage, however it reduces tissue concentratio...

In 1976, a method of growing lettuce and other leafy vegetables on a floating raft of expanded plastic was developed independently by researchers at the University of Arizona and the University of Pisa in Italy. Today facilities exist in a number of countries including the United States, Japan and Canada. Termed “Deep Flow Hydroponics,” the system consists of horizontal, rectangular shaped tank...

The land, water, and energy requirements of hydroponics were compared to those of conventional agriculture by example of lettuce production in Yuma, Arizona, USA. Data were obtained from crop budgets and governmental agricultural statistics, and contrasted with theoretical data for hydroponic lettuce production derived by using engineering equations populated with literature values. Yields of l...

Plant parasitic nematodes, Meloidogyne javanica in particular, cause significant yield losses in sugarcane crops in South Africa. The chemicals at present available for nematode control are expensive and potentially detrimental to the environment. It has been reported that various types of crops reduce the numbers of plant parasitic nematodes. Seven green manure crops (sunn hemp, marigold, oats...
