Ấn phẩm: The Effects of Fertilizer on Burley Tobacco, Nicotiana tabacum
Tóm tắt
Burley tobacco is an important agriculture crop in the southern United States and is a major contributor to farm incomes where it is grown. The effectiveness of tobacco fertilization
application is an important factor in overall quality and yield. Fertilizer is a major input cost in tobacco production. Macronutrients nitrogen, phosphorus, and potassium play key roles in tobacco yield and quality. Research shows, however, that reduced amounts of these nutrients can result in similar quality and yield, while reducing overall cost. Side banding versus the more common practice of broadcasting can help reduce the input cost and also help to improve the quality and yield of the crop. This research took place near Jonesborough, Tennessee during the 2013 growing season. Three different fertilizer methods, side banding, broadcasting, and broadcasting plus side banding, were applied to the research plots to observe effects on height and yield. The research proved that there was a significant difference in plant height and yield. The side banding method produced a taller stalk as well as higher yields when compared to the broadcasting method. However, more nitrogen was applied in the side banding method and this likely affected yields as well. Therefore, it was difficult to determine whether method of fertilizer application alone increased tobacco yields in this experiment. Even so, the side banding method did produce higher yields, equivalent quality, and was more cost effective than the other two methods in this study.
