“…Most importantly, comparing transplanting with direct seeding in both experiments suggest that the RY of sugar beet in the transplanting method was significantly higher than direct seeding in both sites, except the first site in the second experiment (Figure 2). Similar results were reported by Khozaei et al (2020), who showed the transplanting method led to a significant increase (7.7%) in sugar beet yield compared with the direct seeding. Ibrahim et al (2017) also indicated that transplanting sugar beet (45 day old) led to increasing fresh and dry weights of shoot and root, and root length and diameter versus direct seeding.…”

Transplanting is a useful technique to produce sugar beet (Beta vulgaris L.) in arid and semi‐arid regions that face water scarcity and salinity. The major challenge in transplanting is to improve the economic benefits that smallholder farmers have in the self‐production of transplants. The objective of this study was to evaluate the yield, quality, and water use efficiency (WUE) of sugar beet in response to transplanting and different options in transplant production process. Two field experiments were conducted at two sites. The first experiment investigated the effects of seedling age at transplanting, volume of the substrate, and transplanting date. The second experiment investigated the effects of substrate media and transplant production conditions on sugar beet yield and quality. In both experiments, transplanting was compared to the direct seeding on the conventional planting date at both sites. The highest white sugar content (12.1% and 13.5%) and white sugar yield (10.2 and 12.1 t ha−1) were obtained from plants transplanted in mid‐May at sites 1 and 2, respectively. Also, root yield, total sugar content, and WUE were higher in transplanting than direct seeding. The 40‐day‐old transplants produced in 22 mL cell volume when transferred to the field in mid‐May had higher WUE than the direct seeding. The transplants produced outside the greenhouse (uncontrolled conditions) had nearly the same yields as those produced inside a greenhouse under controlled conditions. We suggest that using readily available substrates and not requiring greenhouse conditions for transplant production is a cost‐effective way for smallholder farmers to produce their own seedlings.

“…Increasing IRR significantly increased the root length of sugar beet. Khozaei et al (2020) stated that the root length values ranged from 16.43 to 25.69 cm. Hussein et al (2008) reported that the root length values varied between 16.3-24.0 cm.…”

Present experiments were conducted to determine the effects of different irrigation levels on yield, yield components and quality of drip-irrigated sugar beet under sub-humid conditions. Field experiments were conducted in the 2019 and 2021 growing seasons in the Bursa province of Turkey. Experiments were carried out in completely randomised blocks design with three replications. Irrigations were scheduled based on the replenishment of 100 (S1), 66 (S2), 33 (S3), and 0% (S4) of soil water depletion within the soil profile of 90 cm using 7-day irrigation intervals. In 2019, root yields varied between 29.32 (S4)–86.31 (S1) t/ha and sugar yields between 6.33–13.57 t/ha. In 2021, root yields varied between 26.18 (S4)–74.56 (S1) t/ha and sugar yields between 6.56–12.53 t/ha. Effects of different irrigation levels on investigated parameters were found to be significant (P < 0.01). The crop water consumption values were significantly related to root and sugar yields (P < 0.01). Based on present findings, S1 treatment was recommended to get the highest root and sugar yields. In case of limited water resources, S2 (33% water shortage) treatment with the highest water productivity and irrigation water productivity values could be recommended to ensure maximum efficiency from the applied irrigation water quantity.

“…In addition, higher soil moisture in 2016 led to higher SPAD (vegetation stage) and gas exchange and consequently higher LAI compared to 2015. Interestingly, the transplanting method reduced applied water in a sugar beet ( Beta vulgaris ) field by about 24% and evapotranspiration by 25% as compared with direct seeding [ 31 ].…”

The objective of this two-year field study was to assess the influence of stand establishment methods (direct seeding or transplanting) on root growth dynamics, shoot morphology, leaf physiology, yield, and quality of globe artichoke (Cynara cardunculus). Three artichoke cultivars were evaluated, ‘Green Globe Improved’ (GGI), ‘Imperial Star’ (IS), and ‘Romolo’ (ROM). Plants established with the transplanting method had higher mean root length intensity (La), root length, and root surface area as compared to plants established by direct seeding. The topsoil (0–20 cm) had on average higher La, root length, and root surface area than deeper soil profiles. Transplanted plants had higher plant shoot width and leaf area index (LAI) chlorophyll content index (SPAD) than direct seeded plants at the vegetative stage in 2015. The improvement of root and shoot growth in transplants (compared to direct seeding) also resulted in higher (p < 0.05) marketable yield (21.1 vs. 19.9 ton ha−1 in 2015 and 18.3 vs. 13.7 ton ha−1 in 2016). Additionally, 46–50% of the total yield occurred during the first 30 days of harvest in the transplanting method compared to 13–38% for direct seeding. No significant differences were found between planting methods or cultivars in leaf-level gas exchange (photosynthesis, stomatal conductance, and transpiration) and cynarin concentration in the marketable heads. Although chlorogenic acid was similar in both establishment methods in 2015, direct seeding had higher concentration in 2016. Comparing cultivars, GGI had higher root length, surface area, root volume, and earlier and higher marketable yield than ROM. However, ROM had higher mean root length intensity (La; total root length per specific area in soil profile) than GGI in both growing seasons. This study showed significant and consistent improvements in root and shoot traits, and yield for transplants as compared to direct seeded plants.
