The flower cabbage (Brassica oleraceea L.) is a type of vegetable plant belonging to the family of cabbage plants (Cruciferae). Flower cabbage often called "cauliflower" has many benefits to consume, because it contains calories, protein, carbohydrates, calcium, and vitamins A, B1 and C. Farming is very much affected by the state of agricultural land, a problem that often occurs due to lack of elemental content nutrients in the soil that affect the inflorescence and flower cabbage growth. Therefore, to increase the yield of cabbage flowers offered the method of land optimization with the addition of nutrients in the form of phosphorous soil and also the addition of gibberellin hormone that has a role to flowering cabbage plants. The research was conducted by using Randomized Block Design (RBD) in divided plots with 2 treatments, Phosphorus (P) as the main plot with 3 treatment levels P1 (100 kg / ha), P2 (125 kg / ha) and P3 150 kg/ha then the concentration of Giberelin (K) as a subplot with 3 levels of treatment K1 (75 mg / L), K2 (100 mg / L) and K3 (125 mg / L)). From the result of the combination of the two treatments were 9 treatment combinations, repeated 3 times to obtain 27 units combination of treatments, each experimental plot consisted of 15 plants. Parameters observed include plant height, number of leaves, number of flowering plants, flower diameter and flower weight. The result of the research showed no significant interaction in all plant variables but the dosage of phosphorus fertilizer gave significant effect on the height variable of the 10 hst plant on the P1 (100 kg/ha) treatment, the leaf number variant showed significant effect at age 40 hst on P3 treatment (150 kg / ha), the number of flowering plant variables showed significant effect of 60 hst on P3 treatment (150 kg / ha), flower diameter variables showed significant differences in P3 treatment (150 kg / ha). The best treatment is P3 treatment (150 kg / ha). Gibberellin concentrations did not have a real effect on all plant variants.

Irmawati W, Gofar N. 2020. The effectiveness of mycorrhizal and nitrogen fertilizer on the production of chili (Capsicum annum) in tidal land. Jurnal Lahan Suboptimal : Journal of Suboptimal Lands 9(2): 175-183.Mycorrhizal fertilizer and urea can be used as an alternative to overcome problems in the tidal land that have various obstacles including low availability of nutrients, the presence of toxic compounds, high salinity, and pyrite compounds to be developed as agricultural land. The purpose of this research was to determine the role of mycorrhizal fertilizer and urea on the yield of chilli (Capsicum annuum) in tidal land. The study used a Randomized Block Design Method with 4 treatments including control, Mychorrhizal 10 g, Mychorrhizal 10 g and urea 0,375 g, urea 0,375 g with 5 replicat. So that the total treatments are 20 units. The results show that the application of mycorrhizal fertilizer 10 g had affected on plant height, number of leaves, and leaf area. Plants that have mycorrhizae have the ability to absorb more macro and micronutrient. The presence of fungal hyphae can expand the area of absorption of nutrients and water so that plant nutrients are available. The low treatment of mycorrhizal and urea fertilizers was due to a decrease in fertilizer efficiency because fertilizer was given in excessive amounts.

ABSTRACT The use of humic substances and plant extract has been increasing mainly in organic crop systems without scientific-based recommendations. Research is necessary to evaluate the feasibility and the recommendations of these substances. The objective of this work was to evaluate the effect of humic substances (humic and fulvic acids) applied by fertigation with and without saponin-based plant extracts on growth and yield of ‘BRS Princesa’ banana. The experiment was carried out using the banana cultivar ‘BRS Princesa’, at a spacing of 2.0 × 2.5 m, fertigated by drip irrigation in a Dystric Densic Xantic Ferralsol, at the Recôncavo da Bahia, Brazil. Treatments consisted of five doses of humic substances (0.0; 70; 105; 140, and 210 L ha-1cycle-1) applied with and without a saponin-based plant extract in a randomized block design in split-plot scheme. The following growth variables were evaluated: number of leaves, pseudostem height, pseudostem diameter, and length and width of the third leaf. The number of fruits/hand and hands/bunch, hand and bunch yield, and length and fruit diameter of the second central hand were evaluated during harvest. The doses of humic substances influenced only pseudostem height. Hand yield, as well as fruit length and diameter of ‘BRS Princesa’ banana were higher in plants fertigated with humic substance and plant extract in comparison with plants fertigated with only humic substance.
