Influence of Organic and Potassium Fertilization on Potato Yield and Quality

Abstract

Potato is considered strategic vegetable crop in the entire world. So, two field experiments were conducted in the experimental farm, Faculty of Agriculture, Mansoura University to study the effect of organic fertilization and foliar application with potassium (K) as well as rates of K soil fertilization and their interaction on vegetative growth (plant height, No of leaves/plant, fresh and dry weight), leaves chemical composition (Chlorophyll a, b, a+b, N, P and K), tuber yield (plant yield, No. of tuber/plant and total tuber yield) and its quality (TSS, reducing, non reducing, total sugar, vitamin C, starch and protein). The experiment was conducted in strip split plot design including 12 treatments i.e. 2 organic applications (compost and vermicompost), 2 foliar applications (tap water as a control and K at 2%) and three rates of K soil applications (120, 165 and 214 kg K 2 O/hectare). The obtained results clarified that using compost and foliar application with K at 2% as well 165 kg K 2 O/ha significantly increased leaves chemical contents and tuber quality, while using vermicompost and foliar application with K at 2% plus 165 kg K 2 O/ha gave the highest values of potato growth parameters and yield. Thus, it can be recommended that using compost or vermicompost at 9.5 and 7 ton/ ha and foliar application with K at 2% as well 165 kg K 2 O/ha that gave the highest net return and improve quality of potato tubers.

“…The surface morphology of HZ‐CELL or M‐HZ‐CELL was indicated using SEM analysis. As shown in Figure 3a, the SEM of the blank cotton fabric looks to have smooth fibers 43 . Figure 3b–f shows agglomerated particles on the HZ‐CELL and the M‐HZ‐CELL (M is Ni, Cu, Zn, or Cd) as an indication for the modification of cotton fabric.…”

Impact of Organic Fertilization and some Beneficial Elements on the Performance and Storability of Salt-Stressed Crisphead Lettuce (Lactuca sativa L.)

“…Also, it can increase soil aggregates and thereby raising the leaching of salts away from the root zone. The superiority of enhanced compost compared to plant residues compost may be attributed to that enhanced compost had lower C/N ratio compared with plant residues compost as well as its high content from nutrients (Abd El-Hady et al, 2021;Ghazi et al, 2021;Seadh et al, 2021 andOmar et al, 2022).…”

Nanofertilizers: Transforming Agriculture for Sustainable Food Production

“…Commercial products like NanoMax-NPK and Ferbanat utilize organic micronutrients, vitamins, and probiotics to enhance crop vitality and root zone activities. During the 2012-2013 growing season, research outlined in [11] investigated the influence of nano-fertilizer (Pharmks®) and humic acid treatments on Nigella sativa L. The study revealed notable impacts of varying humic acid levels on several yield parameters, including seed weight, biological yield, number of capsules per plant, seeds per capsule, and harvest index. Humic acid treatments at concentrations of 3 and 6 ml/l produced the best yields.…”
