Table 1 Irrigation regimes used for evaluation of NDT and DT maize inbred lines.
From: Impact of water deficit stress in maize: Phenology and yield components
Seasons | Evaluation | Crop stage |
|---|---|---|
Wet season-2013 | ||
Irrigated | Field | No stress, Irrigation at −30 kPa |
Rainfed | Field | Stress observed during 30–35 DAS and reproductive stage |
Light stress | Rainout shelter | Stress imposed during flowering and grain filling, irrigation at −50 kPa |
Dry season-2013–14 | ||
Irrigated | Field | No stress, Irrigation at −30 kPa |
Mild to mild severe | Field | Mild stress (−40 kPa) at flowering and mild severe (−60 kPa) stress during grain filling |
Mild severe to severe | Rainout shelter | Mild severe (−60 kPa) stress at flowering and severe (−80 kPa) stress during grain filling |
Severe stress | Rainout shelter | Severe (−80 kPa) stress during flowering and grain filling both. |
