Other claims from this paper (11)
- Observation Osmotic adjustment was highest in Arka Meghali, followed by RFS-1.
- Observation Crop water stress index was lowest in Arka Meghali.
- Observation Crop water stress index was highest in Pusa Ruby.
- Intervention effect Water stress significantly reduced stomatal conductance, transpiration, and net photosynthesis in all cultivars.
- Intervention effect Arka Saurabh had a maximum transpiration reduction of 62.4% at fruiting.
- Intervention effect Pusa Ruby had a maximum net photosynthesis reduction of 53.1% at flowering.
- Observation Arka Meghali had the maximum net photosynthetic rate under water stress.
- Association Internal CO2 concentration did not track the decrease in stomatal conductance.
- Mechanism The lack of matching Ci and gs declines may indicate mesophyll limitation to photosynthesis.
- Observation Arka Meghali had the highest gas exchange efficiency under water deficits.
- Recommendation Arka Meghali was recommended for rainfed cultivation.
