Effects of seed coating on establishment and survival of grasses, surface-sown on tussock grasslands

Influence of site on response of ‘Grasslands Maku’Lotus pedunculatusestablishment to seed pelleting and broadcast lime

“…Seed pelleting can increase the germination of oversown seed (Vartha & Clifford 1973) but, as the response varies with season and site (Scott 1975;Dowling 1978), the lack of response in the present experiment was not unexpected. Cullen & Ludecke (1966) also failed to obtain a response from pelleting clover seed oversown on a range of tussock grassland sites.…”

Effect of seed coating on establishment and yield of grasses on a West Coast pakihi soil

“…Seed was oversown into short, sparse vegetation and, hence, it was unlikely that the coated seed would have had an advantage in penetrating to the soil surface. Vartha & Clifford (1973) and Scott (1975) also found it difficult to isolate the specific advantages of coating in relation to trial results.…”

“…Coated seed is being aerially oversown on pakihi soils but there has been no assessment of the benefits from coating, although such benefits have been shown elsewhere (Hay 1973;Vartha & Clifford 1973;Scott 1975). The present trial was carried out to compare the establishment and yield of non-coated with that of coated seed of the grass cultivars commonly sown on pakihi soils.…”

Effect of treading, herbicides, season, and seed coating on oversown grass and legume establishment in easy North Island hill country

“…Coating of seed with an absorbent Sig 5 and nutrient material such as lime or superphosphate has been shown to improve establishment (Vartha & CIifford 1969). Suggested explanations include the action of the coating material in bringing about faster seed imbibition (Dowling et al 1971), as well as improved seedling nutrition (Vartha & Clifford 1973). In Experiment 3, however, with the type of coating materials used, increasing the seed: coat ratio from I : I to I : 10 resulted in only a slight improvement in establishment for legumes in spring only, but large increases (up to 30% for tall fescue) in grasses in autumn only (Table 6).…”
