Can a Winter-sown Catch Crop Reduce Nitrate Leaching Losses after Winter Forage Grazing?
Direct grazing of winter forage crops to feed non-lactating, pregnant dairy cows prior to calving is a common management practice in the New Zealand South Island. However, the high crop yields per hectare grazed, combined with a high stocking density of cows, means this potentially leads to large amounts of urinary nitrogen (N) deposited on bare, wet soil, that in turn, could lead to high nitra...
متن کاملEffects of Mix Cropping of Alfalfa and Annual Ryegrass on Forage Production
Mix cropping of alfalfa (Medicago sativa) and annual ryegrass (Lolium rigidum) may improve forage production in the rangeland and field conditions, especially in spring after the establishment year. In this study, the effects of different sowing rates of alfalfa and annual ryegrass seeds in the replacement and additive series of mix cropping were evaluated on forage yield in first year after th...
متن کاملNative Warm-Season Grasses for Mid-South Forage Production
Vigorous Summer Growth Peak growth of these grasses occurs during summer. They break dormancy in late March and early April and then grow rapidly from mid-May through midsummer. In late summer, growth slows until fall dormancy, usually in October. The maturity dates of the various species vary somewhat, but all follow this pattern. They remain dormant through winter. Five Key Species While ther...
متن کاملLack of Host Specialization on Winter Annual Grasses in the Fungal Seed Bank Pathogen Pyrenophora semeniperda
Generalist plant pathogens may have wide host ranges, but many exhibit varying degrees of host specialization, with multiple pathogen races that have narrower host ranges. These races are often genetically distinct, with each race causing highest disease incidence on its host of origin. We examined host specialization in the seed pathogen Pyrenophora semeniperda by reciprocally inoculating path...
متن کاملForage Yield and Nutrient Uptake of Warm-Season Annual Grasses in a Swine Effluent Spray Field
that ‘Coastal’ hybrid bermudagrass receiving 670 kg N ha 1 and 153 kg P ha 1 from swine effluent removed Five warm-season annual grasses were compared for dry matter an average of 382 kg N ha 1 yr 1 and 43 kg P ha 1 yr 1. (DM) yield and nutrient uptake alongside bermudagrass [Cynodon dactylon (L.) Pers.] on a Brooksville silty clay (fine, montmorillonitic, Adeli and Varco (2001) found that ‘Ali...
