The Effect of Nitrogen (N), Soil Temperature, Soil Moisture, Soil Reaction and Day Length on the Growth and Production of Ryegrass and Clover under Controlled Conditions at Elsenburg | Western Cape Government

The Effect of Nitrogen (N), Soil Temperature, Soil Moisture, Soil Reaction and Day Length on the Growth and Production of Ryegrass and Clover under Controlled Conditions at Elsenburg

Objective:

This research project aims to test and quantify the effect of a single application of nitrogen in combination with soil temperature, soil moisture, soil reaction and day length on the growth and production of ryegrass and clover.

Start: 2001
End: 2004
Status:
Underway
Description:

Four rates of fertiliser nitrogen (0, 50, 100 and 150kg N/ha) are tested in combination with four factors (soil temperature, soil moisture, soil reaction and day length) as separate experiments:

  • N rate and soil temperature (6, 12 and 18 oC)
  • N rate and soil moisture (0.24 - 0.10 mm3/mm3)
  • N rate and soil reaction (pH 3.5 - pH 6.0)
  • N rate and day length (short and long days).

 

Data recorded includes dry matter (DM) production, tiller/stolon production, leaf nitrogen content, root growth and soil nitrogen fractions.
