Abstract:
The aim of this work is to evaluate and quantify the effect of several crop management techniques, such as top dress nitrogen, delayed harvest, and field leaching by rainfall, on the inter-annual yields and the combustion quality of the biomass obtained from different cool season grasses under semi-arid conditions in Spain. Elytrigia elongata, together with its varieties Jose and Alkar were the top performing species at the two studied experimental sites. The soil characteristics as well as the different meteorological conditions throughout the years affected noticeably dry matter yields. Similar dry matter yields were obtained after applying different top dress nitrogen rates (0, 30, 80 N UF ha-1). A delay of two months in mowing (until September) led to a desirable decrease of N, K, and P biomass contents. Leaving the cut cool grasses in the field led to a 30-50% Cl and K depletion (50 mm rainfall).
