Influence of the Virginia Fanpetals Cultivation Method on Calorific Value, Content and Dynamics of Macronutrient Uptake

Abstract

A one-factor field experiment was carried out in 2016-2019 at the Experimental Station in Lipnik near Stargard. The aim of the study was the cultivation of Virginia fanpetals in two systems of sowing and planting, determining the impact of the cultivation system on the yield quantity, calorific value, moisture, content and dynamics of macronutrient uptake by Virginia fanpetals, calculation of the relationship between the yield and NPK intake, calorific value and yield as well as analytical moisture content. Studies have shown that the method of establishing the plantation (sowing, planting) did not have any significant impact on the calorific value of Sida. Statistical analysis indicated that the method of establishing the plantation (sowing, planting) did not have significant impact on the formation of nitrogen, phosphorus and potassium contents in the biomass, while it was significant for magnesium and sulfur. More macroelements was contained in Virginia fanpetals biomass from sowing compared to planting. The total uptake of macronutrients by Virginia fanpetals biomass was higher in the planting cultivation system. In the system of planting cultivation, in the first year of plantation operation, higher dynamics of N, P, K, Mg and S uptake by Virginia fanpetals biomass compared to the sowing system was found. Correlation analysis showed very high degree of correlation between the size of Virginia fanpetals biomass yield and nitrogen and phosphorus uptake.
