Abstract
The response of tomato (Solanum lycopersicum L.) to elevated carbon dioxide (eCO 2 ) conditions under different nutrient management practices was evaluated at College of Agriculture, Vellayani, Kerala Agricultural University during November 2021 to March 2022.The experiment was laid out in Completely Randomized Design with six treatments in three replications with provisions for entrapping CO 2 evolved to create eCO 2 conditions.The results revealed that the growth attributes, plant height, LAI, number of leaves and branches per plant were significantly higher under FYM + glyricidia, while root parameters were maximum in INM, on par with combination of FYM and glyricidia and sole FYM.Physiological parameters viz., chlorophyll content and photosynthetic rate were the highest in INM on par with FYM + glyricidia.Nevertheless, fruit set was poor irrespective of the nutrient management practice adopted.Artificial pollination was found pertinent under eCO 2 .Monitoring the CO 2 release, among the treatments the total release (71,247 mg kg -1 soil) was maximum in vermicompost + poultry manure combination and the lowest (60,895 mg kg -1 soil) in FYM.Soil and air temperatures followed similar trends.Thus, it is evident that the CO2 evolution significantly influenced the vegetative growth and fruit setting in tomato and the higher temperature ensuing the increased CO 2 concentration modified fruiting behaviour in tomato.
