Elevated Co2 And Temperature

Investigations were carried out during 2014 and 2015 to study the effect of elevated CO2 and temperature on growth and yield contributing parameters of bell pepper (Capsicum annuum L.) under open top chamber (OTC) at research farm of Department of Environmental Science, Dr Y.S. Parmar UHF, Nauni, Solan, Himachal Pradesh with four treatments [T1(eCO2): OTC with elevated CO2 550±10 ppm; T2(eT & eCO2): elevated temperature by 1°C and elevated CO2 550±10 ppm; T3(aT & aCO2): ambient temperature and CO2 and T4: natural condition] and each treatment had two varieties (California Wonder and Solan Bharpur) of bell pepper which were replicated thrice. Results revealed that bell pepper recorded maximum plant height, leaf area, yield attributes under eCO2 which were significantly higher than all other treatments. However, the harvest duration and days to first harvest was lowest under eCO2. Higherfruit size as well as fruit weight was recorded with eCO2 followed by eT and eCO2, aT and aCO2 and open natural condition. But maximum number of fruits and highest fruit yield was obtained with natural condition which was significantly superior over eCO2 as well as over eT and eCO2 because increase in temperature negated fruit set due to less pollen viability under eCO2 and eT & eCO2 as compared to open. In open natural conditions due to higher pollen viability and more fruit setting as compared to higher CO2 andtemperature conditions, it resulted more yield. Solan Bharpur recorded higher total fruit yield (800.2 g plant-1) than California Wonder (399.1 g plant-1). Elevated CO2 has positive effect on plant growth and yield attributes in both cultivars of bell pepper. However, under interactive effect of elevated CO2 and elevated temperature, rising temperature negated the positive effects of elevated CO2 on crop production.

Capsicum Annuum L

Bell pepper (Capsicum annuum L.) is highly sensitive to temperature variation and high temperature promotes flower drops and reduce fruit yield. An experiment was undertaken to identify suitable planting time of bell pepper and stable performed varieties for different plating dates during the winter season of 2011-12 and 2012-13 at U.B.K.V., Pundibari, West Bengal, India. The experiment was laid out in split plot design with 3 replications. Three planting dates (15th November, 30th November and 15th December) were allotted in sub plots while 4 varieties (Mekong, California Wonder, JK Peeyali and Asha) were placed in main plots. Bell pepper responded differently with the changes in planting dates irrespective of years. The 30th November planting date emerged best in terms of different and growth and yield attributes. Among the varieties, Mekong emerged as superior in terms of more number of fruits (10.24), fruit weight (65.50 g) and yield (670.76 g/plant and 18.11 t/ha) while maximum beta carotene and vitamin C were recorded in the variety California Wonder (0.071 μg/100g fresh fruits, 154.80 mg/100g fresh fruits, respectively). The interaction effect showed that variety Mekong transplanted on 15th December resulted in many fold improvement in the form of highest leaf area (8.79 cm2), maximum number of fruits/ plant, fruit weight (86.93 g) and fruit yield (854.69 g/plant and 23.08 t/ha). The result established that 30th November is ideal for bell pepper planting and the variety Mekong is the most stable performing variety with respect to the different planting dates.

Global warming is predicted to have negative effect on plant growth due to the damaging effect of high temperature on plant development. The field experiment was conducted during 2014-15 to study effect of elevated CO2 and temperature on growth parameters of pea (Pisum sativum L.) crop in order to check the effect of climatechange on vegetable crops. Effect was studied under four conditions i.e. Open Top Chambers, T1: OTC - elevated CO2550±10 ppm; T2: OTC -elevated CO2 550±10 ppm and temperature 1°C; T3: OTC - ambient CO2 and temperature (reference) and T4: natural condition. Maximum plant height at 50 % flowering was recorded in T1 (84.29cm) at elevated CO2 which differed significantly with T2 (79.47cm) at elevated CO2 and temperature, T3 (73.60cm) at ambient CO2 and temperature and natural condition (70.73cm). Minimum days to 50 per cent flowering were recorded in plants growing under T2 (68.56 days). Maximum pollen viability was recorded in T1 (77.42%) followed by T3 (76.36%), T4 (74.65%) and T2 (69.97%). Internode length of plants grown under T1 was maximum (7.01cm) followed by T2 (6.68cm), T3 (6.00cm) and T4 (5.05cm). Elevated temperature and CO2 had significant effects on growth and development in vegetables. Overall, growth parameters of pea crop were affected positively by elevated CO2 whereas under interaction effect of elevated CO2 and temperature these positive effects of CO2 were offset by elevated temperature effect and hampered the growth of pea crop which interns can affect the yield and quality of crop under changing climate scenario.

A pot experiment was conducted during kharif, 2018 inside CO2 Temperature Gradient Tunnels (CTGT) to assess the effect of elevated CO2 and temperature [T0: ambient temperature & ambient CO2, T1: elevated temperature (ambient +1°C) & elevated CO2 (ambient+25% of ambient) and T2: elevated temperature (ambient +2°C) & elevated CO2 (ambient + 50% of ambient)] under three different transplanting dates (D1: 25th June, D2: 10th July and D3: 25th July) on growth and yield of rice in Jorhat district of Assam. The result showed that occurrence of different phenological stages was earlier under elevated CO2-Temperature conditions resulting in reduction of crop duration by about 8-15 days. On the other hand,days to tiller initiation increased whereas days to panicle initiation, flowering and physiological maturity reduced with delay in transplanting. Yield attributing parameters were improved under elevated CO2-Temperature condition. With respect to dates of transplanting, D2 recorded higher number of panicles hill-1 (17.9) and higher filled grains panicle-1 (156.6). Higher grain yield (55.9g hill-1) was found under T2 which was at par with T1 and it was significant higher over the ambient. Grain yield was significantly reduced when transplanting was delayed after 10th July. The results revealed that the growth and yield of rice was found to be better under elevated CO2-temperature levels when transplanted on 10th July.

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.
