“…This, in turn, leads to increased potato growth (Table 2) and chlorophyll contents (Figure 1), ultimately boosting photosynthesis and energy transfer from leaves to tubers, resulting in higher yield (Table 5). These results align with previous studies conducted by Kandil et al (2012) Results obtained herein showed that soaking tuber before planting in magnetized water increased vegetative growth, chlorophyll contents, nutrients percentage in leaves and tubers in addition tuber yield and quality. This technique may stimulate early root growth, leading to a robust root system throughout the plant's life cycle.…”

“…Soaking potato tubers before planting decreases the sprouting stage of buds, leading to improved growth and also decrease the risks high temperatures by the end of the growing season, which affect potato storage (Kandil et al, 2012;Abd El-Hady et al, 2016;Abd El-Hady and Shehata, 2019;Hamaiel et al, 2021). Magnetized water has been proved to enhance plant growth and development both qualitatively and quantitatively, as well as improve seed and tuber germination.…”

o address the current challenge of rising fertilizer costs and limited expansion of cultivated areas in Egypt, a field experiment was conducted for two successive seasons (2021 and 2022) to evaluate the effect of different tuber soaking techniques before planting and various rates of NPK recommended doses on potato growth and quality attributes. A split plot design with complete randomized blocks, consisting of 15 treatments; the soaking types included no soaking, soaking in normal water, and soaking in magnetized water, while the fertilization rates comprised 100% NPK of the recommended dose, fulvic acid+ 75% NPK from the recommended dose, fulvic acid+ 50% NPK of the recommended dose, biochar+ 75% NPK from the recommended dose, and biochar+ 50% NPK from the recommended dose. The results indicated that soaking tubers in magnetized water before planting yielded the highest values in terms of vegetative growth parameters, chlorophyll contents, ion percentage, potato yield, and quality. Furthermore, plants fertilized with 100% NPK of the recommended dose exhibited the maximum vegetative growth and yield. Likewise, the treatment involving fulvic acid+ 75% NPK showed the maximum values in terms of chlorophyll contents, nutrients percentage, and tuber quality. Based on these findings, it is recommended to soak tubers in magnetized water before planting and fertilize the plants with fulvic acid+ 75% NPK of the recommended dose. This approach can help reduce production costs by 25% while still achieving high potato yield and quality.

The production of potato in two or more cycles within a year is increasing in the country and it is a common practice in most potato producing regions of Ethiopia. However, the characteristic long tuber dormancy of improved potato varieties in Ethiopia constrains double or triple cropping using irrigation during the long dry season of the year. Thus, it is important to break the long dormancy of tubers for early sprouting and timely planting. Therefore, several types of researches were conducted so far to assess the effect of plant growth regulators and other chemicals to assess its effect on tubers dormancy break, sprouting, sprouts growth, and subsequent effect on tuber yield, yield related and tuber quality of potato varieties. For dormancy break, sprouting and subsequent yield various methods of applications (haulm & dipping) and concentration rates were applied. Moreover, the effect of dormancy-breaking treatment and storage methods were conducted. Results of the studies indicated that, tuber dormancy period and sprout vigour were significantly influenced by the interaction of GA3 and variety, while other sprouting as well as sprout growth traits were significantly influenced by the main effects of GA3 and varieties. The interaction effect of varieties and GA3 significantly influenced days to maturity. Planting of tubers treated with the highest concentration of GA3 produced a significantly highest marketable tuber yield. The optimum tuber size (medium size) for planting purpose was attained from planting of tubers treated with 40 ppm GA3. Significant increase in tuber number and weight due to GA3 application contributed to the increase of total tuber yield. Application of GA3 and storage methods as well as the interaction among the varieties and treatments significantly affected tuber dormancy period, sprouting characteristics and subsequent tuber yield. The mean values for tuber quality (DM & SG) related traits increased in response to treating the tubers with higher concentrations rate of GA3 for both methods of application. Potato varieties treated with GA3 showed significantly higher tuber dry matter yields, specific gravity and total starch content than the other variety. The highest net benefit with an acceptable marginal rate of return was attained in response to treating tubers with higher rates of GA3. Therefore, it could be concluded that haulm application and dipping tuber in GA3 at higher concentration increased tuber yield with a possibility of cultivating potato for two to three production cycles in a year that enhance productivity per unit area, food and nutrition security as well as farmers' income.
