“…Across environments (irrigated and drought‐stressed), about twofold variation for seed Fe (25.8–48.9, average 35 mg kg −1 seed) and about threefold variation for seed Zn (13.5–42.6, average 25.8 mg kg −1 seed) was observed (Supplementary Table S1), which is in accord with the results reported in the published literature (Carvalho, 2005; Crusciol et al, 2008; Zhao et al, 2009; Rastija et al, 2010; Farahani et al, 2011; Kandianis et al, 2013), although the variation is less than that reported by Kayodé et al (2006) for Fe (30–113 mg kg −1 seed) among 76 farmer‐preferred cultivars from northern Benin. The performance of controls IS 18758 (Fe) and IS 2205 (Zn) in this study across environments were the best in each maturity group for seed Fe (29.6–34.1 mg kg −1 seed) and Zn (23.9–25.7 mg kg −1 seed).…”

“…Compared with irrigated environments, drought stress significantly increased both seed Fe and Zn concentration in Groups 1 to 4 (Table 2). Published research in the literature have reported increased Fe and Zn concentration under drought stress in crops including barley, lupin ( Lupinus albus L.), maize, pearl millet ( Pennisetum glaucum L.), rice, and wheat (Carvalho, 2005; Crusciol et al, 2008; Zhao et al, 2009; Rastija et al, 2010; Farahani et al, 2011; Kandianis et al, 2013), and this contrasts with the reports that reported no effect of drought on mean seed Fe and Zn in wheat (Feil et al, 2005; Peleg et al, 2008) or reported reduced mean seed Fe and Zn under drought stress in sweet corn (Oktem, 2008; Kandianis et al, 2013).…”

Drought stress invariably reduces yield and may alter seed chemistry. This experiment was initiated to characterize the sorghum [Sorghum bicolor (L.) Moench] mini core collection for genetic variation and to study the effect of postflowering drought on seed Fe and Zn concentrations. Accessions with similar maturity, together with controls, were evaluated in split‐plot design under irrigated and drought‐stressed environments for two postrainy seasons. Residual (or restricted) maximum likelihood (REML) analysis of data considering genotypes as random and drought and year as fixed indicated highly significant variance as a result of genotypes. Highly significant effects of drought (D), year (Y), and D × Y interaction emphasized need for multilocation evaluation of germplasm for agronomic and seed nutritional traits. About twofold variation in Fe (25.8–48.9 mg kg−1 seed) and threefold variation in Zn (13.5–42.6 mg kg−1 seed) concentrations was observed across environments. Eleven accessions with high seed Fe, 14 accessions with high Zn, and nine accessions high in both Fe and Zn were identified. These accessions, however, produced low seed yields. In addition, six and four accessions, respectively, showed 8 to 39% and 9 to 38% greater Fe and Zn over control IS 33844 and produced seed yields similar to that of IS 33844. Significant rank correlation (≥0.70) indicated that accessions with high Fe or Zn under irrigated environments are also expected to perform well under drought‐stressed environments. Significantly positive correlation between Fe and Zn indicated simultaneous improvement as a realistic approach in breeding. The identified germplasm are ideal genetic resources for the development of Fe‐ and Zn‐dense sorghum cultivars.

“…Our results showed that the highest amounts of Ca taken up by leaves and stems in both cuts of both years were in T25 and T50. The data on the effect of water stress on plant Ca content is particularly uncertain, with a general increase being reported in some studies (De Carvalho, 2005), and a reduction being reported in others (Kaya et al, 2006;Yu et al, 2007). In a study researching the physiological and morphological responses of Thymus vulgaris plants to five different irrigation levels, it was reported that the Ca content of the aerial parts varied between 0.8% and 1.25%, with the greatest amount of Ca found in the 80% FC treatment.…”

“…As with calcium, information on the effect of water stress on the magnesium content of plants is unclear and complex. The findings of some studies indicate that water stress increases the amount of Mg (De Carvalho, 2005), while some claim that it causes a reduction (Kaya et al, 2006;Yu et al, 2007). Sarajuoghi et al (2014) reported that water stress significantly affected Mg content in Thymus vulgaris plants, and that the greatest Mg contents obtained were 0.74% in the 80% FC treatment.…”

Mint (Mentha × piperita L.) is a medicinal and aromatic plant known for its high-water requirement. However, water stress is an important factor limiting vegetative development of this plant. Studying the growth, productivity, and nutrient uptake of this plant under various water stress levels is necessary to optimize its fertilization programs. In this study, the effects of different water stress levels and cutting times on the fresh biomass yields and the amounts of nutrient uptake of peppermint by different aerial parts were examined in two consecutive years. The field experiment was arranged as five irrigation treatments (125, 100, 75, 50 and 25% of full irrigation), during the season of maximum water demand (June-September), applied by drip irrigation. Results showed that at all cutting times in both years, the amounts of nutrient elements taken up by the different parts generally increased in parallel with increasing water stress, while fresh biomass yields decreased. However, this increase observed in nutrient element uptake was an increase relative to the dramatic decrease in the number of plants in severe stress conditions. The effect of long-term water stress on the nutrients taken up by different parts of the plant was mostly observed in Ca, Mg, N, Fe and Cu. As a result, in mint growing under Mediterranean conditions, despite the non-significant differences, in terms of the amounts of nutrient elements taken up by aerial parts, T75 treatment which provided 25% water saving compared to T100 could be recommended for one cut and one year cultivation in practice. Severe stress levels are not appropriate in mint growing was concluded.

“…The alkaloid level of lupin (0.5-4%) varies among cultivars, soil type, and growing season (Gladstones, 1970). The mean alkaloid content of marketable sweet lupin seed is on average 130-150 mg kg -1 (De Carvalho, 2005). However, it has been possible to grow sweet genetic varieties with low alkaloid contents ranging from 0.008% to 0.012% (Tsaliki et al, 1999).…”

The study was executed to evaluate the agro-morphological and nutritional performance of four narrow-leafed blue sweet lupin varieties (Australian lupin, Probor, Sanabor, and Vitabor) sown with five seeding rates (60, 70, 80, 90, and 100 kg/ha) during the main cropping seasons of 2014 and 2015 at Holetta in the central highlands of Ethiopia. Randomized complete block design replicated three times in factorial arrangements was used for experimenting. The lupin varieties were sown in rows with an inter-row spacing of 30 cm. At sowing, diammonium phosphate fertilizer at the rate of 100 kg/ha was uniformly applied for all treatments in both years. Data were collected on plant height, dry matter yield, number of pods per plant, number of seeds per pod, seed yield, and nutritive value. All measured data were subjected to analysis of variance using procedures of SAS general linear model. The result revealed that plant height, number of pods per plant, and number of seeds per pod of lupin varieties were significantly (P<0.001) affected by experimental years. The varietal difference was the major cause of variation (P<0.05) for dry matter yield, the number of pods per plant, and seed yield. The Sanabor, Probor and Vitabor varieties had 38, 23, and 20% dry matter yield advantage over the introduced Australian lupin variety, respectively. The Sanabor variety which produced the highest seed yield had 25, 17, and 14% seed yield advantages over Vitabor, Australian lupin, and Probor variety, respectively. The seed yield performance of lupin varieties was positively correlated with the number of pods per plant while it was negatively correlated with the number of seeds per pod. The dry matter yield and number of seeds per pod were also significantly (P<0.05) affected by seeding rates of lupin varieties. The dry matter yield of lupin varieties increased with increasing seeding rates indicating the tested lupin varieties had a low tillering performance. The number of seeds per pod of lupin varieties decreased with increasing seeding rates. On the other hand, the nutritive values did not differ significantly (P>0.05) among the tested lupin varieties. However, Vitabor variety gave better CP and IVDMD followed by Australian lupin while Probor variety gave the lowest CP and IVDMD. Vitabor variety which exhibited better ash, CP, and IVDMD contents produced the lowest NDF, ADF, and ADL contents when compared with other varieties. Generally, Sanabor and Probor varieties had better forage dry matter yield and seed yield but Vitabor and Australian lupin had relatively better nutritive values. For forage production, lupin varieties should be sown with the highest seeding rate (100 kg/ha) while the lowest seeding rate (60 kg/ha) is recommended for seed production. However, this research should be done across locations and over years to prove the above-recommended seeding rates for forage and seed productions in the study area and similar agro-ecologies. Keywords: dry matter yield, herbage quality, plant height, pod number, seed yield, seeding rate.
