Abstract
The study aims to assess changes in soil fertility and determine the type of organic fertilizer and the optimal dose of inorganic fertilizers in increasing the quantity and quality of bulb yield on dry land. A split plot design with two factors was used in this research: the first factor as the main plot is a combination of mulch and organic matter consists of two levels, namely: O1= straw mulch+cow manure, O2= straw mulch+Gliricidia leaves. The second factor as the subplot is inorganic fertilizer consisting of four levels, namely: A0= Without Fertilizers, A1= 50kg urea, 100kg SP-36, 75kg KCl, 100kg ZA, A2= 100kg urea, 100kg SP-36, 150kg KCl, 150kg ZA and A3= 150kg urea, 200kg SP-36,125kg KCl, 200kg ZA. Of the two factors obtained 8 combined treatment with 3 replications, so there were 24 experimental units. The results showed that treatment of organic fertilizer gliricidia leaves (5t ha-1) and inorganic fertilizer treatment at a dose of 50kg urea, 100kg SP-36, 75kg KCl, 100kg ZA increase the quantity and quality of shallot bulbs compared with other treatments. The results of the soil analysis showed that an increase of soil fertility indicated by enhancement of C-organic level from 0.89% to 2.43%. Improved yield quality and quantity indicated by an increase of total soluble solid bulbs and shallot yield from 6.5t ha -1 into 13.91t ha -1.
