Abstract
An experiment was conducted during 2014 and 2015 at Solan, Himachal Pradesh to study the effect of elevated CO2 (eCO2) and temperature (eT) on growth and yield contributing parameters of pea (Pisum sativum L.) crop under four conditions of CO2 and temperature in open top chambers and open natural condition. The study revealed that pea plants performed better under eCO2, with slight changes in development and yield attributing traits, depending on the cultivars. However, the beneficial direct impactof elevated CO2 (eCO2) on crop yield can counteract by elevated temperature (eT). Pooled data for two years indicated that growth and yield attributing traits like plant height, days to first harvest of pods, harvest duration, fresh weight and biomass, number of pods per plant, pod length, pod girth, pod yield were improved under eCO2. However, responses of these attributes were negated with eT. Pea cultivars PB-89 performed well under eCO2 and eT conditions as compared to Azad P-1.
Highlights
Agricultural production system is largely affected due to variability and change in climatic parameters viz. temperatures, rainfall, changes in atmospheric carbon dioxide concentrations as induced by global warming
The lowest number of days to first picking of pods (92.7 days) were recorded under elevated CO2 (eCO2) and elevated temperature (eT) and maximum days were recorded under open natural condition
Lower days to first picking of pods were recorded under eCO2 and eT which may be due to the effect of higher temperature and CO that might hasten the reproductive development of plants and shortened the fruit maturation time which leads to early maturity of fruits
Summary
Agricultural production system is largely affected due to variability and change in climatic parameters viz. temperatures, rainfall, changes in atmospheric carbon dioxide concentrations as induced by global warming. Agricultural production system is largely affected due to variability and change in climatic parameters viz. Temperatures, rainfall, changes in atmospheric carbon dioxide concentrations as induced by global warming. The rise in carbon dioxide levels is associated with an increase in average global temperature. The availability of suitable growing period in India is likely to be impacted seriously by climate change and global warming. The mid hill zone of Himachal Pradesh is endowed with highly congenial climatic conditions for vegetable production. The quantification of impact of elevated CO and temperature on growth and yield attributes of pea in Himachal Pradesh has not been investigated. The present investigation was carried out to study the effects of increasing CO2 concentration and temperature on growth and yield contributing parameters of vegetable crop pea
