ABSTRACT
An experiment is to study the effect of time ofapplication and dose of bokhasi on growth of tobacco seedling (Nicotiana tabacum, L.) of Grompol Kenongo variety. The experiment was carried out from December 22 1997 to February 26 1998 at Mungkid Village, Mungkid District, Magelang Regency. The soil type is latosol with pH 6,0 and altitude 340 metres.

The result of research showed is:
1. The effect time application of bokhasi gives result the highest at height of seedling, number of lateral roots, lenght of main roots, fresh weight of straw and dry weight of straw on tobacco seedling.
2. The effect of dose bokhasi gives result the highest at height of seedling, number of lateral roots, lenght of main roots, fresh weight of straw and dry weight of straw on tobacco seedling.
