Impact of Elevated CO<sub>2</sub> and Temperature on Growth, Development and Nutrient Uptake of Tomato

Elevated carbon dioxide (EC) can increase the growth and development of different C<sub>3</sub> fruit crops, which may further increase the nutrient demand by the accumulated biomass. In this context, the current investigation was conceptualized to evaluate the growth performance and nut...

Interestingly, earliness of phenophases viz., branch initiation (3.0 days), flower initiation (4.14 days), fruit initiation (4.07 days) and fruit maturation (7.60 days) were observed at EC<sub>700</sub> + 2 °C, but it was statistically on par with EC<sub>700</sub> and EC<sub>550</sub> + 2 °C.
