“…Definitely, the irrigated potato plants presented along the crop cycle higher values in stem length. This finding agrees with the statement made by Motalebifarda et al . (2013), who found that lower levels of soil moisture the crops evapotranspiration rates is shortened; this triggers a decrease in the absorption and transport of nutrients, adversely affecting the growth of stems and of the plant.…”

“…The possible reason was due to the environmental factors and growing conditions, for example, potato suffered a series of natural disasters, such as gale, flood and freeze damage during the seedling and flowering stage, which affect the soil water potential in the farmland and the aeration zone among different potato plants, leading to potato tubers absorb more moisture in the process of growth. Motalebifard et al (2013) also indicated that the deficit of soil moisture resulted in a significant increase in the dry matter percentage of Iran cultivar compared with potatoes which were planted in the soil with well moisture. The average starch content was 62.43% DW, which was lower than that of 18 cultivars from Brasil (65.9% DW) (Feltran et al 2004).…”

“…Many former studies have determined the nutritional qualities of potato cultivars which were planted in different areas, and indicated significantly different nutrients among different potato cultivars, which might be related to soil, climate, cultivation technologies, etc (Motalebifard et al 2013;Ngobese et al 2017). However, some studies on Chinese potato cultivars were mainly concentrated on cultivating varieties of high yield and disease resistance (Jansky et al 2009), the information about nutritional and functional properties of different cultivars are scarce.…”

Chemical composition (moisture, protein, starch, ash, fiber, fat), vitamins (vitamin C, vitamin B 1 , vitamin B 2), total polyphenol content, antioxidant capacity, minerals, and amino acid of 14 potato cultivars in China were evaluated. The results indicated that all parameters varied significantly among different potato cultivars. The total starch, crude protein and fat content ranged between 57.42-67.83% dry weight (DW), 10.88-14.10% DW and 0.10-0.73% DW, respectively. Moreover, the consumption of potato increased remarkably the dietary intake of vitamins, K, Mn and Cu. In addition, the chemical score of amino acid varied considerably between different cultivars, which ranged from 54 (Neida3 and Neida41) to 71 (Neida34). Grey relational analysis (GRA) indicated that Neida26 exhibited the most comprehensive nutritional values among potato cultivars, followed by Neida42. Different potato flours had a significant effect on the quality parameters of potato steamed bread (PSB), Neida26 and Neida34 were more suitable for making PSB.

“…In this regard, Renau-Morata et al (2012) observed a decrease in the photosynthetic rate of saffron under water stress. Motalebifard et al (2013) showed that water deficit stress caused a significant reduction in tuber numbers, yield and WUE of potato (Solanum tuberosum L. cv. 'Agria').…”

Saffron’s color, taste and odor result from the chemicals crocin, picrocrocin and safranal, respectively. Hence, in addition to quantitative yield, secondary metabolites content are known as crucial factors for a successful saffron production. Moreover, enhancing resources efficiency, especially water and nitrogen, is becoming increasingly important for agricultural improvement in arid and semi-arid regions. Thus, the effects of irrigation levels and corm planting on crocin, picrocrocin and safranal content, water use efficiency (WUE) as well as nitrogen use efficiency (NUE) of saffron were investigated as a two-year field experiment based on a randomized complete block design arranged in split-plot with three replicates. The irrigation levels (100, 75 and 50% of saffron water requirement) and corm planting pattern (50, 100, 200 and 300 corms m-2) were allocated to main and sub-plots, respectively. Based on the results, crocin and picrocrocin content increased with decreasing irrigation levels. The highest WUES (WUE based on dry stigma yield) was obtained when 50% of saffron water requirement was supplied. However, the lowest WUEC (WUE based on daughter corms yield) and NUEC (NUE based on daughter corms yield) were obtained when 50% of saffron water requirement was applied. Irrespective of irrigation levels, WUES, WUEC and NUEC increased with increasing the planting density. The results demonstrated that although relatively severe water stress increases WUES and secondary metabolites in saffron stigmas, it could decrease WUEC and NUEC through affecting daughter corm growth.
