Lucerne is regarded as the best legume crop for forage to be cultivated in South Africa. It commonly used produce good quality hay. also plays an important role soil conservation, regeneration, and rotation systems it supplies substantial amounts of nitrogen succeeding crops through symbiotic N2 fixation, which makes preferable choice intensive production systems. Fertilizer liquid inoculant fo...

A survey was conducted to determine the status of Lucerne transient streak virus (LTSV) in three high-yielding alfalfa regions in central Saudi Arabia (Riyadh, Qassim, and Hail) during 2014. Three hundred and eight symptomatic alfalfa, and seven Sonchus oleraceus samples were collected. DAS-ELISA indicated that 59 of these samples were positive to LTSV. Two isolates of LTSV from each region wer...

A complete c D N A copy of the viroid-like satellite R N A of the Canadian strain of lucerne transient streak virus (LTSV) has been cloned and the nucleotide sequence of the R N A has been determined using this and other clones. The sequence comprises 322 residues and shares 8 0 ~ homology with satellite R N A s (s tRNAs) of the Australasian isolates of LTSV. A proposed secondary structure for ...

The research was based on a pot experiment, in which the response of eight species of crops to soil contamination with fluorine was investigated. In parallel, some inactivating substances were tested in terms of their potential use for the neutralization of the harmful influence of fluorine on plants. The response of crops to soil contamination with fluorine was assessed according to the volume...

Sheep with oesophageal fistulas were used in sham-feeding experiments to assess how sham intakes were affected by (a) physical form of straw (finely and coarsely ground; ground and pelleted), (b) type of food (straw pellets v. lucerne (Medicago sativa) hay pellets) and (c) additions of monosodium glutamate (MSG) with or without NaCl to the various straw diets. Normal animals were also fed on di...

Non-ammonia nitrogen (NAN) passage to the small intestine and disappearance of NAN in that organ have been studied in multi-cannulated sheep on pasture or fed indoors. Forages under investigation included a number of subtropical grasses, foggages and hay, temperate grasses, lucerne (Medicago sativa), triticale (Triticale X Secale), oven-dried ryegrass (Lolium multiflorum), and the tannin-contai...
