Other claims from this paper (16)
- Association Vegetative growth and physiological activities improved as soil depth increased under dryland and irrigated conditions.
- Intervention effect Irrigation improved vegetative growth relative to non-irrigated treatments at corresponding depths.
- Observation At 800 mm soil depth, dryland vines attained optimum vegetative growth and physiological response in the third year.
- Observation At 1 000 mm soil depth, dryland vines attained optimum vegetative growth and physiological response in the third year.
- Intervention effect Loosening soil to 1 200 mm induced excessive vine growth.
- Observation Irrigation produced sufficient vegetative growth by the second season in 800 mm soil.
- Observation Irrigation produced sufficient vegetative growth by the second season in 1 200 mm soil.
- Observation In irrigated 400 mm soil, sufficient vegetative growth occurred only by the third season.
- Intervention effect At the third season, irrigation stimulated excessive vigour in 800 mm soil.
- Intervention effect At the third season, irrigation stimulated excessive vigour in 1 200 mm soil.
- Observation In year three, consumption with 800 mm irrigated soil was comparable to the full-bearing vine norm.
- Association Greater soil depth induced greater vegetative growth and evapotranspiration.
- Observation Overly vigorous three-year-old vines in 1 200 mm soil consumed 614 mm of water.
- Observation Growth-limited vines in 400 mm soil consumed only 387 mm of water.
- Recommendation The authors recommend reducing first-season irrigation to 44,6% of the amount for bearing grapevines.
- Recommendation The authors recommend reducing second-season irrigation to 65,5% of the amount for bearing grapevines.
