Impact of Care and Nutrition Methods on the Content and Uptake of Selected Mineral Elements in Solanum tuberosum

Abstract

The aim of the study was to evaluate the content and uptake of macronutrients (P, Ca, Mg, K) in Solanum tuberosum tubers and the effect of care with biostimulants from a three-year field experiment conducted at the Agricultural Experimental Station in Zawady, Poland. The experiment was set up in a split-plot arrangement with three replications. The first factor was two varieties of edible potato (Oberon and Malaga), and the second factor was five treatments with herbicide and biostimulants: (I) control facility, (II) herbicide (chlomazone + metribuzin), (III) herbicide and biostimulant PlonoStart, (IV) herbicide and biostimulant Aminoplant, (V) herbicide and biostimulant Agro-Sorb Folium. Biostimulants and herbicide increased the concentration of P, Mg, Ca, and K compared to tubers harvested from the control facility. The Oberon variety had the highest macro-nutrient uptake capacity. The application of herbicide with biostimulants increased the uptake of the mentioned mineral nutrients compared to the control variant. Climatic conditions affected the content and uptake of selected elements.

Design of a Spring-Finger Potato Picker and an Experimental Study of Its Picking Performance

“…The potato is one of the most widely grown crops worldwide due to its high yield and unique nutritional value [1]. In 2015, China categorized the potato as a strategic staple food; under the development process of the national grain growing industry structure adjustment and potato staple food strategy, China's potato planting area and total production have become some of the best in the world.…”

Humic Substances: Importance for Agriculture, Affinity and Interactions with Soil Amendments and Pollutants

“…The application of five different treatments using biostimulants and herbicides in two edible potato varieties demonstrated increased P, Mg, Ca, and K uptakes compared with the control samples. The macroelement uptakes were affected by the cultivars, the herbicide-biostimulant application method, and the weather conditions [10].…”
