An experiment was conducted to determine the effect of Titoniabokashi on the changes in the level of uptake of natrium (N) and yield of onion (Allium ascalonicum L.) on entisol by giving an application of Titonia bokashi on Entisol. The research wasarranged inRandomized Block Design(RBD) with dose ofbokashias follows:to= withouttreatment t1 = 5 t ha-1t2 = 10 t ha-1t3 = 15 t ha-1t4= 20 t ha-1t5 = 25 t ha-1t6 = 30 t ha-1. Each treatment was repeated three times so that there were 21 experimental units. The applicaton of Titonia bokashiuptoa dose of 30tha-1was proveneffectively increaseC-organic, N-total, plant dry weight, plant N-concentration, N uptake, wet and dry weightof onionbulbsvariety ofPaluValley. The highest level of nitrogen uptake (16,09g) can beachieved at a dose of 30tha-1, and maximum wet and dry weight ofonion bulbsperclumpachieved ata dose of 30 t ha-1.
