The effect of goat manure and Fortune liquid organic fertilizer on the growth and yield of leek (Allium porrum L.) Blaze F1 variety

One alternative that can be done to increase national agricultural production is to utilize dry land which has very extensive potential.However, due to low land productivity as a result of low fertility levels, fertilization efforts need to be carried out. The research aimed to determine the effect of goat manure and organic liquid fertilizer (POC) of Fortune and their interaction on the growth and yield of leek plants and to obtain the appropriate dose of goat manure and concentration of POC Fortune for leek plants. The research was carried out from January to March 2024 in Nehas Liah Bing Village, Muara Wahau District, East Kutai Regency, East Kalimantan Province. The research used a 3 x 3 factorial experiment in a Completely Randomized Design (CRD) which was repeated 5 times. The first factor is the dose of goat manure fertilizer (K) consisting of 3 levels: without goat manure fertilizer (k0), 5 tons/ha equivalent to 125 g/polybag equivalents to 5 tons/ha (k1), and 250 g/polybag equivalent to 10 tons /ha (k2). The second factor is the concentration of POC Fortune (F) consisting of 3 levels: without POC Fortune (f0), 10 ml/l water (f1), and 20 ml/l water (f2). Research activities are as follows: preparation of planting media, preparation of leek seeds, treatment with goat manure 2 weeks before planting, planting, treatment with POC Fortune, plant maintenance, harvesting, and preparation of reports. The research results showed that (1) goat manure (K) treatment had a very significant effect on plant height 60 days after planting and plant wet weight. The highest wet plant weight was produced in the 250 g/polybag (k2) treatment, namely 117.00 g/plant, while the lowest was produced in the treatment without goat manure (k0), namely 77.67 g/plant; (2) POC Fortune treatment had a very significant effect on plant height 60 days after planting, root length, and plant fresh weight. The highest wet plant weight was produced in the 20 ml/l water (f2) treatment, namely 111 g/plant, while the lowest was produced in the treatment without POC Fortune (f0), namely 70 g/plant; (3) there is no interaction between goat manure treatment and POC Fortune (KxF) on all observation parameters.
