Machfudz (Balai Penelitian Tembakau dan Tanaman Serat, Malang (Indonesia))
An experiment to study the effect of Potassium-ash as a source of potassium on growth and yield of Flue-cured tobacco, was conducted on Entisol Wlingi Blitar from May 1996 to February 1997. Two the experiment was arranged in Completely Randomized Design with two factors and replications. The first factor were sources of potassium, KNO3, ZK and Potassium-ash. The second factor were five potassium dosages 50, 100, 150, 200, and 250 kg K2O/ha. These treatment-combination were arranged in Randomized Block Design factorially with four replications. The result indicated that Flue-cured tobacco was able to absorb potassium from Potassium-ash the same with from KNO3 and ZK and has a positive effect to dry leaf. The chlor content of cured-leaf was lower than that tolerated level allowed
