Application of organic fertilizer and Pseudomonas fluorescens on the growth and yield of shallot cultivar Sabu Raijua (Allium ascalonicum L .) in dry land

Abstract

The specific objectives of this study were 1 ) knowing certain types of organic fertilizers on the growth of shallots 2 ) knowing the concentrations of Pseudomonas fluorescenss certain the growth of shallots, 3 ) knowing the types of organic fertilizers and the concentrations Pseudomonas fluorescens specificity increase the optimal yield of shallots. To achieve this goal, this research was conducted using factorial experiments with a split Plot Design with 10 treatments and 3 replications. So that there are 10 treatment combinations of a total number of 30 experimental plots. There were 2 factors that were tried, namely the first factor of Organic Fertilizer as the main plot, namely: cow manure 10 ton ha-1 (K1), chicken manure 10 ton ha-1 (K2). While the second factor as the subplot is the concentration of Pseudomonas fluorescens: Watering with water (as a control) 100 ml (P0), Watering with a concentration of Pseudomonas fluorescens 5 ml + normal water 95 ml (P1), Watering with a concentration of Pseudomonas fluorescens 10 + ordinary water 90 ml (P2), sprinkling with a concentration of Pseudomonas fluorescens 15 ml + 85 ml plain water (P3), Flushing with a concentration of Pseudomonas fluorescens 20 + ordinary water 80 ml (P4). The shallot cultivar of Sabu Raijua which was given organic fertilizer of 10 tonnes of chicken manure. Ha-1 and a concentration of Pseudomonas fluorescens 20 + 80 ml of plain water gave the highest growth component at the age of 10 WAP, namely at the age of 10 WAP, namely plant height (37.667cm). Leaves (34, 800 trees), number of tillers (10, 533 trees). The results of shallot bulbs of Sabu Raijua cultivar from organic fertilizer treatment of 10 ton ha-chicken manure1s with a concentration of Pseudomonas fluorescens 20 ml + 80 ml water resulted in components, namely tuber weight per plot (276.70 g ), number of tubers per plot (291, 70 tubers ).
