“…This supports results obtained by Suckling (1976). In an evaluation of Grasslands white clover varieties on hill country at Ballantrae the resident white clover population performed most satisfactorily, particularly during autumn when it appeared that this material was more capable of surviving and recovering from a dry summer than the overs own varieties.…”

“…The exception was the stockcamp sites which contained high levels of both white and suckling clovers, largely owing to transfer of buried seed in livestock droppings. Hard legume seeds, collected during grazing, pass through the alimentary tracts of livestock without being digested (Suckling 1952) and would be incorporated into the upper soil layers when the droppings decomposed.…”

Numbers of buried legume seeds in the upper layers of soil were determined in a survey over an area of hill country pasture at the Grasslands Division research station, Ballantrae. Seeds of suckling clover (Trifolium dubium L.) and white clover (T. repens L.) were most numerous, mean numbers per ln 2 being average for this particular type of pasture (2541 and 291 repectively). White clover seed numbers were not significantly different between site types, whereas suckling clover seeds were highest on north aspects and stockcamps and lowest on south aspects and wet sites. These variations could be attributed largely to climatic and stock behaviour factors, and distribution of legume plants. Little of the buried legume seed germinated in tests, but scarification revealed that viability was high. The role of buried legume seed as a source of seed in pasture improvement is discussed. 211

“…Most comparisons conducted within New Zealand have similarly found that Pitau has given a higher yield than Huia over the cool part of the year (Barclay 1970;Lambert et al 1970;Smetham 1972;Suckling 1976;Vartha & Clifford 1978).…”

A medium-leaved certified white clover (Tr(fo/ium repens L. 'Grasslands Huia'), a largeleaved white clover ecotype from Spain, and a hybrid of these ('Grasslands Pitau'), were grown as spaced plants in the field in the South Island, New Zealand. A comparison of the components of herbage yield obtained from measurements of growth on a marked stolon showed that during winter, late winter, and spring, the leaf dry matter (OM) yield of the Spanish ecotype exceeded that of Huia by up to 70%. There was little difference in the total number of leaves formed per stolon, the number of leaves grown per unit stolon length, or specific leaf weight. and hence OM yield differences resulted from the considerably larger area per leaf developed by 'Spanish', which was between 70% and 100% larger than that of Huia. Pitau was mostly intermediate in leaf character, sometimes aligning with Spanish and sometimes with Huia. The superior leaf growth of the larger leaved white clovers during all three observation periods agrees with other observations on the temperature responses of these cultivars, i.e., superiority at either 'Iow' or 'high' temperature -in this instance, monthly mean temperatures were all 'Iow'. Although the periods of observation were relatively short, some results su'ggest that leaf longevity may be greater for largeleaved ecotypes. Stolons grown by the ecotype from Spain were almost twice as heavy as those from Huia on a weight per unit length basis. Pi tau was intermediate. Otherwise, stolon growth was little different between cultivars for length and number. Other reports on the performance of white clovers, together with the results obtained in this investigation, lead to the conclusion that any condition which impairs the expression of potentially larger leaf size will reduce or eliminate the herbage production superiority of the larger leaved white clovers.

“…Rates of seedling establishment recorded 11 weeks after sowing were within the range expected for white clover in North Island hill country. Suckling (1976) recorded 9.0-10.7% establishment of oversown Huia seeds 17 weeks after autumn sowing, whereas Chapman & Fletcher (1985) recorded 37.5 and 51.8% of seeds establishing for Tahora and Huia respectively 11 weeks after overs owing in May 1983. Chapman & Fletcher (1985) also recorded higher establishment rates for Huia than for Tahora after oversowing in May 1982, and the relative establishment rates of the two cu1tivars recorded in this experiment are consistent with those earlier results.…”

Pastures based on the white clover cultivars Grasslands Tahora and Grasslands Huia ",:ere established by oversowing into unimproved hIll country at Ballantrae in May-June 1986. Each pasture type occupied 2.2 ha, and a further 2.2 ha of unamended pasture containing the resident clover ecotype was also included. From August 1988, four ferti1i~er treatments (control, receiving no fertiliser; reactive phosphate rock; partially acidulated phosphate rock; and a superphosphate/phosphate rock blend, the latter three applied at 35 kg Plha per year) were superimposed upon pasture types. Emphasis was placed on identifying the population and plant characteristics which responded to treatment, and defining the relative benefits to pasture performance resulting from the two approaches to pasture improvement (cultivars versus fertiliser). Based on measurements of the frequency of occurrence of cyanogenic plants in populations nearly 4 years after sowing, 58% of white clover plants in the Tahora-sown pastures and 43% of plants in the Huia-sown pastures were estimated to have derived from the original seedlines. The rest A92063 Received 1 December 1992; accepted 15 February 1993 of these populations were volunteer plants of the resident ecotype; these were much smaller than plants ~f Tahora and Huia (mean total plant weights, Includmg root material, were 49.5, 112.2, and 139.2 mg, respectively). When both genotype frequency and plant weight differences were accounted for, the introduced cultivars were estimated to have contributed 70% of the total white clover biomass present in sown pastures, averaged across fertiliser treatments. White clover herbage accumulation was greater in the sown pastures than in the resident pasture (558 and 586 kg DMlha per year for Huia-sown and Tahora-sown pastures respectively, versus 305 kg DMlha per year for resident pasture, means for Years 3 and 4 after sowing), and in the fertilised treatments compared to the Control (518-597 kg DMlha per year versus 231 kg DMlha per year respectively). Applying 35 kg Plha per year had a greater influence on clover herbage accumulation than cultivar introduction, though returns on cultivar introduction can be seen as accruing each year (if cultivars are persistent) for a one-off cost whereas fertiliser must be financed annually. Fertiliser application increased mainly the population density of clover plants (number/m2) whereas cultivar introduction affected mainly the mean size of plants in the population. Limited evidence was obtained to suggest that Tahora and Huia responded differently to fertiliser application.
