Shallot (Allium ascolanicum L.) is a leading vegetable commodity that gives <br /> <br /> the third biggest national contribution which is widely used as food seasoning and <br /> <br /> traditional medicine substance. The application of NPK inorganic fertilizer is <br /> <br /> needed by shallot plant to suffice its nutrition so that it can grow optimum and able <br /> <br /> to produce high quality bulb. This research is aimed to know the effect of four <br /> <br /> different dosage of NPK fertilizer application on growth and yield of shallot mini <br /> <br /> bulb Tuk Tuk variety originated from TSS, and also to know which dosage of NPK <br /> <br /> fertilizer gives the best result. The variables observed are the average of plant <br /> <br /> height and leaf amount in harvest time, fresh and dried tuber stover weight, tuber <br /> <br /> stover weight loss, mini bulb weight, mini bulb diameter, and the percentage of mini <br /> <br /> bulb yield achieving the suitable criteria for a seed. The dosages of NPK fertilizer <br /> <br /> used in this research are the standard and modified fertilizer dosage of PT. East <br /> <br /> West Indonesia, which are no fertilizer application (control), NPK 50% SOP, 100% <br /> <br /> SOP, and 150% SOP. Result shows that the application of different dosage of NPK <br /> <br /> fertilizer gives a significant effect on growth and yield of shallot mini bulb Tuk Tuk <br /> <br /> variety originated from TSS (True Shallot Seed) for the observed variables of the <br /> <br /> average plant height and leaf amount in harvest time, fresh and dried tuber stover <br /> <br /> weight, mini bulb weight, and mini bulb diameter, but has no significant effect on <br /> <br /> tuber stover weight loss. The dosage of NPK fertilizer which gives the best results <br /> <br /> on growth and yield of shallot mini bulb for all variables observed is the dosage of <br /> <br /> NPK 100% SOP.
