Nutrition Effect to Productivity of Bioenergy Crop Miscanthus X Giganteus in Different Environments

Abstract

Miscanthus x giganteus Greef et Deu is a perennial C4 grass, originally from East Asia. Morphological productive characteristics of miscanthus were analyzed in this study: plant height in the tasseling period, number of leaves on stalk in the tasseling period, number of stalk in tiller, number of stalk with tassel, dry plant yields, stalk moisture in harvest time and cellulose content. The miscanthus achieves high yields and excellent performance in summer drought conditions because it has a well-developed root system. In the period April-October 2018-2019 there was less precipitation (428 mm and 431 mm) than the optimal needs of the plants (550 mm). In the two-year average the miscanthus had a stalk height of 342.4 cm and achieved a yield of 31.4 t ha -1 . To these morphologically productive traits significantly affected weather conditions, nitrogen nutrients as well as the interaction of the factors studied.

Production Characteristics of Miscanthus (Mischantus × Giganteus Greef et Deu) under Agroecological Conditions of Serbia

“…Studies of quality of miscanthus stalks grown in different agroecological conditions in Serbia, Refs. [6,7], concluded that growing conditions and applied agrotechnical measures did not have any major impact on the chemical composition of aboveground biomass, since during the maturation of plants, i.e., stalks, the highest percentage of nutrients is transferred to rhizomes. Two-factor analysis of variance of the examined traits is presented in Table 7.…”

“…It is characterized by extremely strong growth and high genetic potential for fertility [6], and is becoming important as an energy crop. As a consequence of its triploidy, miscanthus does not produce fertile seeds, so there is no possibility of the plants spreading outside their plantations and forming weeds in surrounding agricultural areas [7]. Miscanthus is mainly grown for the production of biofuels from aboveground biomass.…”
