“…This may be attributed to reduced pollen viability, flower drop or failed fertilization which may lead to decreased pod development. Flowers per inflorescence and number of pods per plant are the most important characters influencing pod yield under current (Lyngdoh et al, 2017) and in elevated CO 2 conditions (Rao et al, 2015). Water stress post-flowering accelerated the leaf and pod senescence (Cayetano-Marcial et al, 2021).…”

Background: Elevated temperature and water stress are the key limiting factors affecting the kidney bean yield. Climate change is projected to enhance these risks for successful crop production. However quantified information, which is limited, on temperatures stress at various growth phases in combination with water regimes, becomes important for optimizing management decisions for higher productivity of kidney bean. The current study is aimed to fill this gap. Methods: A field experiment was conducted during January-April 2020, to investigate the effect of irrigation and temperature regimes on growth parameters and yield of kidney bean. Temperature treatments imposed were elevated temperature for entire crop period i) ~4.6°C ii) ~3.1°C iii) ~2.8°C above mean ambient (19.6°C), iv) ambient temperature Tmax and Tmin regime of 25.9/13.4°C (mean 19.6°C), v) elevated temperature during pre-flowering phase (~3.7°C above mean ambient during that period, 19.6°C), vi) flowering phase (~5.3°C above mean ambient during that period, 23.1°C) and pod-filling phase (~5.2°C above mean ambient during that period, 28.9°C). These were combined with i) two irrigations (applied at sowing and seedling phase) and ii) three irrigations (additional irrigation at pod-filling phase). Result: Elevated temperature regimes led to shortening of the crop duration. LAI, NDVI, net photosynthesis and seed yield were higher in plants exposed to continuous elevated temperature. Heat shock during pre-flowering and flowering led to reduction in yield. Despite exposure to elevated temperature, supplemental irrigation led to higher yield. Seed yield loss was greater when temperature stress coincided with water stress. The negative effects of high temperature were significantly curtailed by provision of supplemental irrigation.

“…Since Blackgram is a C3 crop, the impact of this mild heat stress might be counteracted by CO 2 increment (Vanaja et al, 2006). The increase in CO 2 concentration favours growth, physiology and biochemical processes (Ziska and Ebi, 2021) including increase in net photosynthesis (Rao et al, 2015). Similarly, Vanaja et al (2007) also reported that the blackgram grown in controlled chamber at 550 ppm CO 2 reported 86.8 percent increase in pod weight and Jyothi lakshmi et al (2013) reported an average increase in seed yield by 23.75 percentage.…”

Climate change is no longer a distinct prognosis but become a reality and also proved to have its impacts on crop production. Blackgram, a C3 short duration pulse crop was considered for this study to clarify the controversial statements on adaptability of this crop for changing climate. Dynamically downscaled data (CCSM4 data using REGCM4.4 model) for 1971 to 2099 (RCP 4.5 scenario) was used for the study. The popular cultivars CO6 and VBN6 of Blackgram are employed for the study after calibration and validation of DSSAT model. The impact assessment was carried out with August 1st as sowing date. The yield of Blackgram was found to have beneficial stimulus towards the changing climate under enriched CO2. Considering cultivars, difference was noticed spatially and temporally. The average yield of VBN6 was less than CO6 during base and near century, but it got reverse with time.

“…In June of 2021 [1] global CO 2 concentrations were 418.7 ppm, but these are predicted to double by the end of this century [2] Elevated CO 2 (eCO 2 ) is known to affect plant growth, crop yield and nutritional status of agricultural products. Although it seems to induce higher growth and yield [3][4][5][6][7][8][9] a number of studies making use of meta-analysis methodologies showed reduced mineral or protein concentrations in several crop species such as wheat, barley, rice, common bean, soybean, among others [10][11][12][13][14]. In previous studies, eCO 2 has been reported to induce photosynthesis [15], stomatal closure [2,16,17] and increase the levels of leaf organic acids concentrations [18][19][20].…”

Elevated CO2 (eCO2) has been reported to cause mineral losses in several important food crops such as soybean (Glycine max L.) and common bean (Phaseolus vulgaris L.). In addition, more than 30% of the world’s arable land is calcareous, leading to iron (Fe) deficiency chlorosis and lower Fe levels in plant tissues. We hypothesize that there will be combinatorial effects of eCO2 and Fe deficiency on the mineral dynamics of these crops at a morphological, biochemical and physiological level. To test this hypothesis, plants were grown hydroponically under Fe sufficiency (20 μM Fe-EDDHA) or deficiency (0 μM Fe-EDDHA) at ambient CO2 (aCO2, 400 ppm) or eCO2 (800 ppm). Plants of both species exposed to eCO2 and Fe deficiency showed the lowest biomass accumulation and the lowest root: shoot ratio. Soybean at eCO2 had significantly higher chlorophyll levels (81%, p < 0.0001) and common bean had significantly higher photosynthetic rates (60%, p < 0.05) but only under Fe sufficiency. In addition, eCO2 increased ferric chelate reductase acivity (FCR) in Fe-sufficient soybean by 4-fold (p < 0.1) and in Fe-deficient common bean plants by 10-fold (p < 0.0001). In common bean, an interactive effect of both environmental factors was observed, resulting in the lowest root Fe levels. The lowering of Fe accumulation in both crops under eCO2 may be linked to the low root citrate accumulation in these plants when grown with unrestricted Fe supply. No changes were observed for malate in soybean, but in common bean, shoot levels were significantly lower under Fe deficiency (77%, p < 0.05) and Fe sufficiency (98%, p < 0.001). These results suggest that the mechanisms involved in reduced Fe accumulation caused by eCO2 and Fe deficiency may not be independent, and an interaction of these factors may lead to further reduced Fe levels.
