“…Therefore, more efficient symbiosis under control condition also showed more effectiveness of symbiosis under drought stress. The results of this study agree with the studies of Mhadhbi et al (2008), Pimratch et al (2008) and Mhadhbi et al (2009) who reported that high biomass production and nitrogen-fixing capacity under stress conditions is due to high potential biomass production under non-stressful conditions. In this study, root dry weight under non-stressful and stressful conditions was independent of the inoculated rhizobial strain which is consistent with results reported by Elsheikh and Wood (1995) and Mhadhbi et al (2004).…”

Chickpea plants were inoculated with two strains of Mesorhizobium ciceri: local strain (C-15) and non-local strain in order to evaluate plant growth parameters, activities of nitrogenase and antioxidant enzymes under drought stress as well as control condition within 15 days of imposition of drought stress. Biomass production, nodulation, nitrogen fixation and antioxidant enzyme activities under drought condition were compared. Under control condition, symbiotic efficiency in symbiosis formed by C-15 was higher than that in symbiosis derived by CP-36. Although drought stress decreased shoot dry weight, root dry weight, nodule dry weight and nitrogen fixation in both symbioses, the rate of decline in plants inoculated with CP-36 was higher than that in symbiosis chickpea with C-15. Therefore, symbioses showed different tolerance level under drought condition which was essentially correlated with symbiotic performance at nonstressful conditions. Under drought stress, nodular peroxidase (POX) activity increased in both symbioses but was higher in nodules produced by C-15. Ascorbate peroxidase (APX) increased significantly in nodules of symbiosis of chickpea with C-15. Catalase (CAT) and glutation reductase (GR) declined in both symbioses which decline extent in symbiosis with C-15 was lower than that in the nodules of CP-36. These results suggested contribution of rhizobial partner in enhancing the tolerance of symbioses to drought stress, which was related with the increase of antioxidant enzyme activities (APX and POX) under drought conditions.

“…higher productivity potential, or its ability to maintain high production, i.e. less yield reduction under drought stress (Pimratch et al, 2008). However, the relative contributions of these two attributes to high crop yield of Jerusalem artichoke under drought conditions of resistant varieties have not been studied.…”

The objectives of this study were to determine the effects of drought on tuber yield, total biomass, harvest index, water use efficiency of tuber yield (WUEt) and water use efficiency of biomass (WUEb), and to evaluate the differential responses of Jerusalem artichoke ( JA) varieties under drought stress. The 3 × 5 factorial combinations of three water regimes (Field capacity (FC), 50% available soil water (50%AW) and 25%AW), and five JA varieties ( JA 60, JA 125, JA 5, JA 89 and HEL 65) were arranged in a pot experiment in a randomized complete block design with four replications for two years. Data were recorded for tuber dry weight, total biomass, harvest index, WUEt and WUEb at harvest. Drought reduced tuber dry weight, total biomass, harvest index, WUEt and WUEb, and reductions were more severe under the severe drought stress of 25%AW. Varieties were significantly different for all traits under drought and well-watered conditions. The JA varieties were classified into three groups. The first category was comprised of the JA 5 variety with high tuber yield potential and low drought tolerance, the second category consisted of JA 60 and JA 125 varieties with low tuber yield potential and high drought tolerance, and the third group included JA 89 and HEL 65 varieties with low tuber yield potential and low drought tolerance. The multiple regression analysis showed that tuber yield, total biomass and harvest index at 50%AW and 25%AW depended largely on the reductions of tuber yield, total biomass and harvest index under drought. Therefore, the results of this study recommend that the selection of JA genotypes with low reduction in yield under drought stress could be a criterion in drought resistance breeding programs for development of JA varieties with high tuber yield under drought stress. JA with drought tolerance in this study means high tuber yield under drought conditions. JA 5 had high yield and WUEt across water regimes and could be used as parental source for drought tolerance breeding programs in further research.

“…Its cake is used as feed or for making other food products and haulms provide quality fodder. Groundnut yield in rainfed areas is limited by drought stress because pod yield and yield attributing parameters have been severely affected (Pimratch et al, 2008,). Yield losses have been estimated to be 56-85 % (Nageshwar Rao et al, 1989) depending on the crop growth stages when the crop is exposed to drought, drought intensity and drought duration (Nigam et al, 2005).…”

Groundnut yield in rain fed areas has been limited by drought stress because pod yield and other growth parameters have been severely affected. The aim of this study is to evaluate the genetic variability, character association and path analysis between yield and its contributing traits in 30 groundnut genotypes under drought. Analysis of variance revealed the existence of significant differences among genotypes for all characters studied. The magnitude of PCV and GCV was moderate to high for number of pods per plant, dry haulm yield, kernel yield, plant height and dry pod yield. High heritability coupled with high genetic advance as per cent of mean was observed for kernel yield, plant height, dry pod yield, and hundred kernel weight indicating the role of additive gene in expressing these traits. Dry pod yield was significant positively correlated with kernel yield, no of pods per plant, hundred kernel weight and SPAD chlorophyll meter reading (SCMR). Path coefficient analysis indicated that number of pods per plant and hundred kernel weight were essential traits to be considered for realizing the improvement in yield.
