Rainfall Map

In dealing with this subject it is essential to define the high rainfall districts, and on, perusing a rainfall map it was found, contrary to expectations, that the greater part of the North Island, as represented by the Auckland Province and Taranaki, has a rainfall of over 50 inches per annum. In the same category falls the West Coast of the South Island and all of Stewart Island.

ABSTRACT In order to improve the management and maintenance of the quality of life of captive wild birds, this study aimed to assess the food preferences of cockatiel chicks (Nymphicus hollandicus) kept in captivity. Thirty-two cockatiel chicks, three to 12 months of age, were kept in a galvanized, wire-netted vivarium with six ceramic feeders, two for an extruded diet, two for a dry-mashed diet and two for a seed mixture. Both extruded and dry-mashed food are commercial psittacine diets. Three round ceramic pots were used to provide water. The birds were exposed to 12 hours of artificial light (40 W incandescent lamps) during the experimental period of 27 days. The birds were observed by video filming, daily, through an ad libitum observation technique. The food consumption was 3.34±0.42g/bird/day of extruded feed, 1.58±0.44g/bird/day of dry-mashed diet and 3.73±0.10g/bird/day of seed mixture. In conclusion, the cockatiel chicks preferred the seed mixture and the extruded food over the dry-mashed diet.

The installation of a permanent ground cover in vineyards offers numerous agronomic (soil protection, soil fertility) and environmental (reduced leaching of nutrients and of plant protection products, reduced use of herbicides, biodiversity) benefits. Nevertheless, such ground covers are not always free of drawbacks (competition for water and nitrogen, increased risk of frost, management). For the growers, the challenge is to manage the green ground covers in such a way as to preserve their advantages while limiting these drawbacks. Among the tools available to the winegrower is the sowing of a seed mixture composed of selected species: a choice depending of the soil and climatic conditions of the parcel, but also of the different, and sometime contradictory, objectives of the grower. This paper lists the agronomic and environmental issues addressed by the installation of a permanent ground cover in vineyards. It describes two concrete situations – ground cover for vineyards integrated in agro-ecological networks and green cover on the row of vines (as alternative to glyphosate) – for which, according to the objectives and the impacts, a choice of plant species is proposed. At last, it presents the trials now carried out to validate and optimize those selections, as well as the first observations and results gathered to date.

Fraser Valley

An artificial pasture was established using a forage seed mixture commonly used in the Fraser Valley of British Columbia. For five growing seasons, the plots were subjected to all combinations of two fertilizer levels, four frequencies of mowing, and the removal or not of small divots to create small gaps. All species were still present at the end of the study, but only Dactylis glomerata was found in all treatments; the abundance of ryegrasses (Lolium spp.) and clovers (Trifolium spp.) declined considerably, and there were significant [Formula: see text] between-year differences for all species. Mowing [Formula: see text] and fertilization [Formula: see text] had significant impacts on the abundance of all species, and there was a significant [Formula: see text] fertilization × mowing interaction effect on all species except Festuca sp. Divot removal had little impact. The number of species per plot and species diversity were highest, but the abundance of species was lowest, in unfertilized and frequently mown plots. The results are discussed in the context of tolerance to shading, nutrient application and growth rates, and competitive exclusion. Key words: mowing, fertilization, disturbance.

Satisfactory results were obtained from seeding forage mixtures at any of four dates at successive 2-week intervals between the end of May and July 15. For each of the four subsequent seeding dates substantial yield reductions occurred. The loss in yield between the fourth and the eighth seeding date averaged 45, 25, and 15% for the first, second, and third harvest years respectively for a seed mixture including timothy, alfalfa, red clover, and alsike. Corresponding yield reductions for a mixture of bromegrass, alfalfa, and ladino clover were 75, 25, and 15%. In each case the loss in the third year amounted to.65 tons of dry matter per acre. Legume establishment and contribution were greatly reduced at the later seeding dates as indicated by inclined point quadrat surveys. Timothy performed somewhat better than did bromegrass at the later planting dates and both responded better than legumes to delayed planting. Weed and bare ground amounts were greater with each successive planting date. By the end of the third harvest year species composition differences attributable to planting date were practically eliminated.
