Abstract
'Perenne' is a perennial rye variety of interspecific origin (Secale cereale x S. montanum) registered in Hungary. The green yield, dry matter, crude protein and fibre content of 'Perenne' were determined. Green mass at the early stem extension was 7.52 t ha-1 and at the late one 19.66 t ha-1. Maximum green weight was measured at heading (23.91 t ha-1) and started to decrease later. Dry matter content was found to be 1.35 t ha-1 at the early stem extension, whilst 3.91 t ha-1 at the late stem extension phase. Dry weather in spring (2003) explains slow rate of increase in dry matter content and the substantial decrease in green weight following heading. Fibre content was 22% in the tillering and the early stem extension stage, which was followed by a steady increase until heading (34.3%) and a gradual decline following ripening stage. Crude protein changed more significantly than fibre content. Early stem extension had the highest value (30.7%). A rapid decline was observed during late developmental stages. For grazing purposes, the early stem extension stage seems to be the optimum ones, when the plant height is approximately 30 cm with the highest crude protein (30.7%) and low fibre (22.2%) content. For cropping purposes, the late stem extension phase was shown to be the optimum one because this provides high green mass along with relatively high crude protein (23.2%) content
