“…Under drought conditions, an increased root depth would contribute to better drought tolerance (Kashiwagi et al, 2006) because the osmotic gradient is sufficient to allow water uptake when the roots contact wet soil (Vadez et al, 2007). Peanut genotypes that have a higher root length density in deeper soil layers have an enhanced drought tolerance (Songsri et al, 2008;Jongrungklang et al 2012). Therefore, it could be that DTGs, with their deeper root distribution, take up more nutrients from lower soil layers to help the plant against the effects of drought.…”

“…The differences between DTGs and DSGs in response to midseason drought for nutrient uptakes could be possibly due to root responses to drought. During midseason drought, the roots of DTGs were distributed in lower soil layers more so than the roots of susceptible genotypes (Jongrungklang et al, 2012). Roots play an important role in drought adaptation in deep soils, where a relation between root depth and pod yield has been established (Vadez et al, 2007).…”

“…Subplots contained 5 peanut genotypes with different levels of drought tolerance. Tainan 9 is a widely planted cultivar in Thailand, but it has low dry matter production (Vorasoot et al, 2003) and is sensitive to drought (Jongrungklang et al, 2012). KS 2 is a released cultivar in Northeast Thailand, but it is also susceptible to drought.…”

“…KS 2 is a released cultivar in Northeast Thailand, but it is also susceptible to drought. KKU 60, a large-seed cultivar, is a newly recommended cultivar and tolerates drought (Jongrungklang et al, 2012). ICGV 98305 is a droughttolerant line from the International Crops Research Institute for the Semi-Arid Tropics, with high biomass production and pod yield under drought conditions (Nigam et al, 2005).…”

The objective of this study was to investigate the responses of peanut genotypes to midseason drought, regarding in particular nutrient uptakes and their correlations with biomass production and pod yield. The experiment was conducted during the dry seasons of 2011/12 and 2012/13. Five peanut genotypes with different levels of drought tolerance and 2 water regimes (well-watered and midseason drought) were laid out in a split-plot design with 4 replications. Midseason drought was imitated by stopping irrigation at 30 days after planting (DAP) and then rewatering at 60 DAP. The data were recorded for contents of N, P, K, Ca, and Mg in plant tissues, biomass production, yield components, and pod yield at harvest. The results showed that midseason drought significantly reduced the uptake of all nutrient elements. Peanut genotypes with higher levels of drought tolerance took up more nutrients than those with lower levels. The uptake of all nutrient elements contributed to biomass production, pod yield, and the number of pods per plant. ICGV 98305 was the best genotype with the highest uptakes of all observed nutrient elements.

Different peanut yields under terminal drought might be due to the different nutrient uptakes among peanut genotypes. Nutrient uptake was presumed to be a drought-resistant trait and might involve drought tolerance mechanisms. The aims of this study, therefore, were to characterize the effect of terminal drought on peanut nutrient uptake and to investigate the genotypic variability of nutrient uptake and its interactions with terminal drought. Field experiments were conducted at the Field Crop
