Riccardo D'Andria; Fabrizio Quaglietta Chiarandà; Vincenzo Magliulo; et al. Agronomy Journal 1995. doi:10.2134/agronj1995.00021962008700060014x
Other claims from this paper (10)
- Intervention effect Spring sowing produced significantly higher seed yield than summer sowing.
- Intervention effect Irrigation was needed for high production, especially in summer crops.
- Observation Three waterings gave the best results only in 1989.
- Intervention effect Two waterings yielded similarly to meteorological irrigation while using water more efficiently.
- Intervention effect Two waterings performed better than one irrigation.
- Observation The actual-to-reference evapotranspiration ratio was 20% higher between R1 and R6 for summer crops than adopted coefficients.
- Observation The ratio was 30% higher for spring crops than adopted coefficients.
- Intervention effect Irrigation positively affected all yield components.
- Observation Achene oil concentration was lower in summer crops.
- Intervention effect Adequate irrigation increased achene oil concentration, especially during grain filling.
