P and K effects on N partitioning during regrowth of Italian ryegrass

Phosphorus and potassium are essential elements for normal growth and development of plants.Phosphorus deficiency is revealed as leaf shape distortion and also leads to a reduction in the number of leaves ( Rao et al.2006 ).P deficiency also decreased N uptake and translocation of NO-3 from roots, due to decreases in primary root elongation and shoot regrowth (Kim et al.2003).Potassium deficiency induces reduced growth and development, shortening of internodes followed by bushy appearance, cholorosis and necrosis, affecting reproductive growth and sugar translocation.The objective of this study was to investigate the effects of P and K deprivation on N partitioning during regrowth of Italian ryegrass.
