“…The decrease in canopy diameter was significant under severe drought stress irrespective of the control ( F = 8.70; p < 0.05). This finding is in line with the work of Al-Mahmud et al [ 73 ]; which showed that canopy diameter was significantly decreased under severe drought stress in potato plants. These might be due to the traits they inherited, and they may determine the yielding potential of the crop.…”

Red pepper (Capsicum annum L.) is an increasingly important economic crop in the world. Thus, this study aimed to investigate the growth, physiological, and biochemical responses of red pepper cultivars under drought stress conditions. A pot culture experiment was conducted in a completely randomized design with three replications, four treatments, and three cultivars. Totally, 36 pots and six seeds per pot were used to grow the seeds. After five weeks, the cultivars were exposed to different drought stress conditions (100% FC or control, 80% FC or low stress, 60% FC or moderate stress, and 40% FC or severe stress). All the collected data were subjected to an analysis of variance (ANOVA). Shoot length was reduced significantly ( p < 0.05 ) in the Hagerew cultivar under severe drought stress. The photosynthesis rate was reduced by 21.11% ( p < 0.05 ) in the Mitmita cultivar under severe drought stress. The highest percentage reduction of chlorophyll content (77.28%) was recorded in the Hagerew cultivar. Both Markofana and Mitmita responded to drought stress by increasing the accumulation of proline and phenolic compounds. The root-to-shoot ratio was increased significantly in both Markofana and Mitmita cultivars (27.91% and 50.92%), respectively, under drought-stress conditions. This study depicted that the cultivar Mitmita was the most drought-tolerant cultivar among the three cultivars.

“…According to Haverkort and Struik (2015) the number of sprouts that will develop depends on how many stems there will be produced per seed, and how many stems will survive and become tuber-bearing will depend on variety, seed tuber size, seed tuber health, physiological age, and environmental conditions. Vice versa, the number of above-ground organs per plant is mainly determined by the size of the tuber and its condition, and the pre-sprouting period also influences it (Al-Mahmud et al 2014). In this sense, farmers manipulate the average tuber size and tuber size distribution to reduce seed quality as a yieldlimiting factor.…”

The growth analysis is relevant to understanding and comparing in terms of physiological and productive behavior varieties. The study aims to determine the accumulation and distribution of dry matter through different phenological stages of development in four diploid potato varieties. For this, in a randomized complete block design with three replications, four varieties of diploid potato were evaluated: Paola, Violeta, Primavera, and Paysandú. Based on direct measurements of leaf area and dry matter of each organ, it was computed the growth indices of relative growth rate (RGR), net assimilation rate (NAR), leaf area relation (LAR), and source-sink relation. The duration of development stages of flowering, fruit, and tuber development was measured in terms of thermal time. Furthermore, the number of stems, stolons, and tubers was measured, and the yield was registered at the cycle end. The varieties Paola and Primavera reached a greater accumulation of dry matter in each organ and a greater number of tubers by plant about the varieties Paysandú and Violeta. The organs with the greater biomass accumulated were the leaves, stems, and tubers. The source and demand power had a considerable correlation between the NAR and RGR, which increased toward the end of the cycle for Paola and Primavera varieties. The yield and the beginning and duration of the growth stages were related to the season and the varieties.

“…Water deficit stress is one of the most important factors limiting the growth and yield of plants. To screen genotypes tolerant to drought stress in potatoes, from the distribution of assimilates and total live weight produced under stress conditions (Coleman, 2008), the ability to survive in severe water deficit stress conditions without losing leaves (Coleman, 2008), maximum leaf area index (Deshi et al, 2015), maximum leaf area index (Deshi et al, 2015), later leaf fall in dry conditions (Lahlou et al, 2003), maximum leaf area index and leaf durability period (Al-Mahmud et al, 2014), maximum the leaf surface index and its retention time (Deshi et al, 2015) and the highest relative water content and the chlorophyll index and the lowest electrolyte leakage rate (Nouri et al, 2015) are used. Water deficit stress is a common stress in potato production, leading to decreased tuber quality and yield.…”

The goal of this study is to increase the tuber yield of potato cultivars by using of nutrient solution of sulfonated silicon with S8 sulfur element and to choose the most suitable method of using the nutrient solution under water deficit stress and normal conditions. This study was performed based on a split factorial experimental design in three replications in Ardabil Potato Research Station, IRAN in 2022. The main factor includes three levels of irrigation (100, 75, and 50% of plant usable water); the second factor includes foliar spraying with a nutrient solution in four stages of plant growth [(1) Tuber formation; (2) Tuber bulking; (3) Tuber formation and tuber bulking; (4) Control (Without nutritional solution)] and the third factor included three potato varieties (Agria, Rona and Takta). A nutrient solution of Sulfonated silicon with S8sulfur element was used for 5 liters per thousand of water. During the growth period, plant height, main stem number per plant, tuber number and weight per plant, tuber yield and water use efficiency were measured. The results showed that foliar spraying with a nutrient solution of sulfonated silicon with S-8 sulfur element amount 5 liters per thousand of water in the stages of tuber formation and tuber bulking increased tuber yield and water use efficiency under normal conditions (100% of plant usable water) about 14.24 ton per hectare and 2.44 kg/m3, under mild stress condition (75% of plant usable water) about 7.04 ton per hectare and 1.61 kg/m3 and under severe stress condition (50% of plant usable water) about 5.50 ton per hectare and 1.89 kg/m3, respectively. The use of the nutrient solution of sulfonated silicon with S8 sulfur element amount 5liters per thousand of water in the stages of tuber formation and tuber bulking increased tuber yield and its components and water use efficiency under normal, mild and severe conditions.
