- Endang Anggraini, 2009. “The Utilization of Mycorrhiza to Improve Deli Tobacco (Nicotiana tabacum L.) Growth and Production in Drought Stress Condition”. Supervised by Prof. Dr. Ir. Rosmayati, MS. as the chief of commission, and Dr. Ir. Chairani Hanum, MP. as the commission member. Deli tobacco is a plant that has economic value as a source country income. Deli tobacco varieties which have been planted such as Deli-4 and F1-45 were sensitive varieties to drought stress. Therefore, it needs a special condition such as microbial technology input like mycorrhiza that can be used to decrease drought stress effect. The objective of this research were to study the using of microbial technology in improving deli tobacco adaptation on drought stress condition. Beside of that, mycorrhizae was expected to increase deli tobacco growth and production. This research was conducted in a green house of Deli Tobacco Research Station-PTPN II, Sampali, Medan, from March until May 2009. The research used split-split plot design with three factors. The first factor were mycorrhizae inoculation and without inoculation. The second factor was soil water content were 80%, 60%, and 40% field capacity. The third factor was deli tobacco varieties were Deli-4, F1-45, and FIN. The parameters were plants height, stem diameter, number of leaves, thickness of the leaves, leaf area index, leaf production, shoot dry weight, root length, root volume, root dry weight, relative growth rates, net assimilation rate, P uptake, and percentage of mycorrhizal infection. The result of this research showed that simbiosis mycorrhiza with deli tobacco can not minimize drought stress effect. However, inoculation of mycorrhiza to AM-F1-45 variety with 60% field capacity tended to improve tobacco growth.
