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 ).

Effects of water hyacinth compost and biological agents (Trichoderma sp) on the growth and yield of shallots (Allium ascalonicum L.) in dry land

“…concentration that stimulated higher yield components of Bima variety. Lende et al (2020) stated that genetic factors were more dominant in affecting plant characteristics than environmental factors.…”

The Effect of The Combination of Bioslurry and Spacing on The Growth and Yield of Shallots (Allium Ascalonicum L.) Varieties of Bima Brebes

“…In accordance with the opinion of Maghfoer et al, (2022), the use of planting spacing and the right dose of bioslurry can increase plant growth and yield, including the weight of fresh bulbs of onion plants. Furthermore, the results of Lende et al, (2020), said bioslurry is an organic fertilizer that contains macro and micro nutrients that are needed by plants for growth and development, if given with the right dose will increase plant generative yields such as the weight of fresh plant tubers Remarks : The average number followed by the same letter in the same column shows no real difference based on the Scott-Knott Cluster Test at a real level of 5%.…”

“…If the number of leaves formed is increasing and supported by the availability of nutrients and getting enough sunlight on all the leaves, then many leaves are able to produce high tubers, then the yield increases. According to Lende et al, (2020), the number of onion saplings formed will produce bulbs, and affect plant yields. Thehigher the number of saplings, the more the yield of onion crop production.…”
