Abstract:
The purpose of this research is to find out the drought effect on growth and physiological effect on tobacco, varieties of Deli-4. This study uses a non-factorial randomized design group with seven water levels (P) such as P0 (300 ml/polybag), P1 (30ml/polybag), P2 (60 ml/polybag), P3 (90 ml/polybag), P4 (120 ml/polybag), P5 (150 ml/polybag), and P6 (180 ml/polybag). The seeds used are varieties of Deli-4. The research is done at Tobacco Plant Research Hall of Deli, Sampali, Deli serdang District, the Province of North Sumatra. The results show that the seven water levels significantly effect the tobacco`s growth and physiology , and the level of water from 300 ml/polybag to 30 ml/polybag can inhibit the growth of tobacco plant, as well as increase the root length and levels of nicotine.
