Effect of Localized and Epsidodic Nutrient Supplies and Salinity on Growth of Selected Grass Species
Publication Date
1993
Location
New Zealand
Description
The efficient use of non•uniform nutrient supplies may be an important component of plant nutrient relationships in soils, especially where inputs of available nutrients by mineralisation may be slow and unpredictable. The experiments reported here examined the effects of periodic supplies of nutrients as well as localised nutrient supplies on the growth of grass species which are common in cultivated soils and pastures. Most plants cannot produce significant yields when grown under saline conditions owing to the difficulty the plant has adjusting to the osmotic potential of the growth medium and its limited capacity to cope with accumulated c1· and Na+ ions. As little is known about the responses of many forage species to salinity, this study compared plant growth responses and osmotic adaptation in different grass species supplied with increasing concentrations of NaCl.
