Influence of Tuber Soaking Times With Some Nutrients on Potato Growth and Productivity

Abstract

Two field experiments were conducted at 2018 and 2019 seasons at private farm in Talkha, El-Dakahlia governorate, to evaluate the effect of soaking times of some nutrients and their interaction on vegetative growth characters, photosynthetic pigments, yield and tuber quality of potato. The experiment was arranged in split plot design in complete blocks randomized. This research included 15 treatments consist of three soaking times of nutrients (1 hour, 2 hours and 3 hours) and 4 nutrients application i.e., NPK, zinc (Zn), boron (B), Zn+B in addition control treatment (tap water). Obtained results cleared that soaking tubers pre planting 3 hours gave the maximum values of vegetative growth characters, photosynthetic pigments, yield and tuber quality. All nutrients application significantly increased measured parameters compared to the control treatment. NPK gave the highest values of vegetative growth characters, photosynthetic pigments, yield and tuber quality. Thus, It can be recommended that soaking tuber pre planting 3 hours with NPK enhanced potato growth, yield and quality.

Impact of tuber soaking types and fertilization rates on growth and productivity of potato

“…Phosphorus also serves as a structural component in many organic compounds within plants (Gardener et al, 1985). Potassium is crucial for enzyme activity, general metabolism, and leaf growth, particularly in relation to photosynthesis (Abd El-Hady et al, 2021). These findings are consistent with studies by Singh and Raghar (2000) and El-Metwaly (2020).…”

“…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.…”

Optimizing Potato Yield and Quality Via Organic and Mineral Potassium Sources

“…In Egypt, the importance of potato cultivation cannot be overstated, as it ranks among the primary crops contributing to the nation's food supply and economic stability. The adaptability of potatoes to various agroclimatic conditions and their relatively short growth cycle make them a favorable choice for cultivation in Egypt (Hamaiel et al, 2021).The government is taking proactive measures to promote the expansion of potato cultivation areas due to its immense significance as both a staple crop and a potential source of export revenue. Recognizing the vital role of potatoes in addressing food security and supporting economic growth, the focus on enhancing potato production has become a key priority for sustainable agricultural development in the country (Abd El-Nabi et al, 2022).…”
