Nitrogen fertilization rates affect quality and curing characteristics of tobacco during the harvesting period under field chilling stress.

ABSTRACT:

Introduction

Field chilling stress during the maturation phase significantly impairs tobacco productivity and leaf quality. Nitrogen (N) management is a crucial agronomic approach for enhancing leaf quality and curing attributes; however, its specific role under chilling stress conditions remains poorly understood.

Methods

Field demonstrations employed 'Honghuadajinyuan' tobacco cultivar under varying N fertilization rates, i.e., T1 (18.9 kg N ha^-1), T2 (27 kg N ha^-1, conventional rate), and T3 (35.1 kg N ha^-1) with uniform basal application of 15,000 kg ha⁻¹ composted farmyard manure. This study evaluated the quality characteristics of fresh and cured tobacco leaves, as well as the curing process, by integrating physical and chemical analysi
