Objectives: The aim of this experiment was to investigate the effect of nutrition management and planting arrangement on the quantitative and qualitative characteristics of two varieties of Virginia tobacco (Nicotiana Tabacum L.).
Materials and methods: The split factorial experiment was conducted in the form of a basic design of randomized complete block design with eight treatments and three replications in 2018-2019. The treatments included the use of N and K fertilizers, planting arrangement and two varieties of tobacco.
Findings: The results showed that TC100 variety had more leaf area plant, height and green yield than NC100 variety. Also, the plant height and the SPAD value were higher in the treatment of foliar fertilizer × two row cultivation. NC100 variety in single-row cultivation showed higher leaf nitrogen. Leaf nicotine in NC100 variety in both planting cultivation conditions was higher than TC100 variety in the same conditions. Leaf K and sugar contant in TC100 cultivar in two-row cultivation recorded a significant increase. The price of tobacco was affected only by the simple effect of the variety. A kilogram of TC100 leaves has higher price than NC100. The income of tobacco under the interaction of TC100 cultivar was higher than NC100 cultivar in both planting arrangement and fertilization treatments.
Conclusion: the results showed that the TC100 variety in two-row cultivation had higher green yield, income and quality characteristics than the NC100 variety. Among studied treatments, fertilization has not significantly affected the quality properties of tobacco leaves.
