Quantifying morphological stage to improve the organisation of the feeding system and enhance yield and quality of sulla and lucerne

A better knowledge of forage legume production physiology in different environments is
necessary to exploit their potential, through new harvesting and grazing systems. The paper reports the results of
several experiments under different environmental conditions on lucerne (Po Valley) and sulla (Sardinia and
central Italy) with the aim of relating the codified stage to forage quality. The OM digestibility, which is known
to be the most important determinant of the nutritive value of forage, resulted to be inversely related to the stage
evolution of both legumes. The use of the quantified morphological stage proved to be an easy pre-harvest tool
to enhance yield and quality of legumes and to determine cutting or grazing schedules, for a profitable
management of the crop.
