Variations of the concentration of several elements (N, P, K, Ca, Mg, Na, Zn, Cu, Fe, Mn, B, Mo) in the blades of four types of sugarbeet leaves collected 94, 114, 134 and 157 days after sowing were evaluated. The types of leaves chosen were the following: a young centre leaf (B), the youngest fully expanded leaf near B (A2), the next older leaf below ...

This study aimed to develop near-infrared spectroscopy (NIRS) calibrations for nitrogen (N) and carbon (C) contents of sugarcane (Saccharum spp.) leaves. The performances of two portable (LabSpec5000 and Phazir1018) and one laboratory (XDS) spectrometers were compared using samples collected from field trials with three sample preparation states (green,
