plants, some white clover plants survived for 2 to 3 yr at a pH as low as 4.2 (Voigt, unpublished data, 1996). Establishment of small-seeded legumes on strongly acid soils can Thus, acid-soil resistance at seedlings stages may be even be even more difficult than maintaining those stands once established. more critical than acid-soil resistance at older stages of Our objectives were to use a soi...

Effluent from a swine (Sus scrofa domesticus) lagoon is often applied repeatedly to nearby fields because of logistical constraints and costs of transportation. To minimize accumulation of soil nutrients and sustain use of spray field, best management practices must maximize the rates of removal of manure nutrients. Research determined summer hay and nutrient yields of bermudagrass [Cynodon dac...

A common crop rotation in the west Iran is wheat-fallow-corn. The fallow period after wheat harvest (during fall and winter) can lead to soil erosion, nutrient losses (e.g. nitrate leaching) and offsite movement of pesticides. This period is an ideal time to establish a cover crop. In order to investigate the effects of different autumn-bseeded cover crops on subsequent irrigated corn response ...

As a preliminary experiment to measuring milksolids (fat plus protein) production of dairy cattle grazing swards containing different levels of white clover (Trifolium repens L.) nine Jersey and nine Friesian cattle housed indoors during late lactation and fed diets containing either 20, 50 or 80% white clover with the balance perennial ryegrass (Lolium perenne L.). During the first 10 day meas...

The aim of this study was to assess the associative effects between orchardgrass () and red clover () silages as a model of preserved grass-legume mixture on voluntary intake parameters and digestive efficiency in sheep. Ten sheep were assigned to a repeated 5 × 5 Latin square design, in which 5 proportions of orchardgrass and red clover silages were tested (0:100, 25:75, 50:50, 75:25, and 0:10...

For one of Canada’s most important regions crop production—the prairies—it’s uncertain if cover crops can be successfully integrated into rotations; so, will soil nitrogen (N) cycling influenced to benefit main crops? To address these gaps, we compared a rotation with (CC) vs. without (LR) from 2018 2021 in Saskatoon, SK. The were grown sequence wheat–canola–potato–pea; the included red clover,...

Pyroglyphid house dust mites are the most common cause of allergic symptoms in humans. An assessment was made of the toxicity of basil, Ocimum basilicum L, essential oil, 11 basil oil constituents, seven structurally related compounds, and another 22 previously known basil oil constituents to adult American house dust mites, Dermatophagoides farinae Hughes. The efficacy of four experimental spr...

Oilseed rape (OSR; Brassica napus ) is a globally important crop which increasingly under pressure from pests, pathogens and weeds. We investigated the potential of achieving multifunctional protection benefits by intercropping oilseed with legumes. A field experiment was conducted in winter intercropped annual frost sensitive legumes berseem clover ( Trifolium alexandrinum or spring faba bean ...
