- Observation Grass yield peaked in central hill positions at approximately 6.5 t/ha.
- Observation Grass yield was lowest on upper hillsides and hilltops at approximately 5.2 t/ha.
- Method / resource Relative yield units significantly reduced the climate contribution to data variability.
- Observation Yield indicators showed maximum coincidence of temporal dynamics at upper elevations.
- Association Climate conditions had no significant yield impact at upper elevations.
- Association Changes in active temperature sums had the greatest influence on grass yield.
- Association Temperature sums correlated negatively with yield on powerful and medium-powerful binomial soils.
- Association Temperature sums correlated positively with yield on low-powerful binomial soils.
- Association Absolute grass yield had an inverse relation with active temperature sums before cutting and in September.
- Association Absolute grass yield had a direct relation with temperature sums in the second half of summer.
- Association Increasing temperature sums reduced relative yields on sandy soils.
- Association Increasing temperature sums optimized production on loams and light loams.
- Association Soil hydromorphism governed the main temperature influence on absolute yield.
- Association Water exchange, slope exposure and soil texture determined the temperature impact on relative yield.
