Ameliorative Impact of Calcium-Magnesium and Calcium- Zinc Rich Products on Potato Growth, Tuber Yield and Quality in Newly Reclaimed Soil

Potato is considered one of the most important vegetable crops for supplying the world's nutritional needs.For healthy growth, production, and tuber quality, potato needs a lot of nitrogen, phosphorus, and potassium fertiliser as well as a lot of other crucial nutrients like calcium and magnesium.Therefore, this research work was conducted to examine the effects of calcium, magnesium and zinc commercial fertilizers(Manni-Plex®Ca-Mag, and Ca-Zn) at ratios of 350 cm/100L.fad(0.24, 0.13, 0.15 g/L for Ca, Mg and Zn, respectively) and 450 cm/100L.fad(0.32, 0.15, 0.17 g/L for Ca, Mg and Zn, respectively)on potato growth and productivity.This experiment was carried out at a private farm in the El-Kassasin region,Ismailia, Egypt during the two 2021 and 2022 winter seasons.Five treatments were organized as a randomized complete block design with four replicates.Results displayed that the exogenous application of Manni-Plex® Ca-Mag and Manni-Plex® Ca-Zn at ratios of 350 cm/100L.fadand 450 cm/100L.fadsignificantly improved plant fresh weight, chlorophyll content, and plant dry weight as well as tubers yield, tuber quality (dry matter percentage, starch and protein contents), and shoot and tuber content of N, P, K, Ca, Mg, and Zn.In conclusion, the foliar application of Manni-Plex® Manni-Plex® Ca-Mg, and Ca-Zn at a ratio of 450 cm/L.fad may be a superior option for enhancing potato plant growth and tuber quality in sandy soils.The current results propose that foliar addition of the aforementioned fertilizers can be a promising approach to improving potato growth and productivity in.newly reclaimed soil.
