A preliminary study of spatial distribution and plant density in a leucaena-grass planting in north Corrientes, Argentina

In northeast Argentina, most beef cattle graze naturalized range pastures continuously, with limited winter supplementation and restricted access to improved pastures. Calving rates are low, averaging 40‒50% annually and calf weaning weights average 150‒170 kg at 6 months. Overall, productivity rema...

Summary:In northeast Argentina, most beef cattle graze naturalized range pastures continuously, with limited winter supplementation and restricted access to improved pastures. Calving rates are low, averaging 40‒50% annually and calf weaning weights average 150‒170 kg at 6 months. Overall, productivity remains low (30‒40 kg LW/ha/yr), mainly due to poor cattle nutrition (Goldfarb et al. 1993; Goldfarb and Casco 1994). In past decades, several improved grass and legume species were evaluated as a strategy to overcome this problem (Goldfarb et al. 1993; Goldfarb and Casco 1998) with Leucaena leucocephala (leucaena) showing definite potential.
