INTERAKSI PEMBERIAN PUPUK KANDANG AYAM DAN POC DI GROW TERHADAP PERTUMBUHAN DAN PRODUKSI BAWANG MERAH (Allium cepa L)

Increasing productivity can be done by meeting plant nutrient needs through fertilization. Chicken manure as an organic material can play a role in forming a good and stable soil structure so that infiltration and the ability to store water is high and permeability increases and can reduce the amount of surface runoff so that it can improve the physical properties of the soil. DI Grow liquid organic fertilizer (POC) can stabilize soil pH and increase the efficiency of fertilizer absorption in plants. The research was carried out at the experimental garden of the Faculty of Agriculture, Lancang Kuning University. The research was carried out for 3 months, starting from January to March 2024. This research was carried out experimentally using a factorial Completely Randomized Design (CRD), which consists of two factors, namely A (chicken manure) which consists of 3 levels, and factor D (POC DI Grow) which consists of 3 levels. Based on the results of the analysis of variance, it shows that the interaction of chicken manure and POC DI Grow has a significant effect on all observed parameters, namely plant height, number of leaves, number of bulbs, wet weight of tubers, dry weight of bulbs and bulb diameter of shallot plants, and the results of further tests can be obtained. It is known that the interaction of chicken manure and POC DI Grow is significantly different for all treatments. The lowest treatment was A0D0 (without giving chicken manure and POC DI Grow) and the highest was treatment A2D2 (giving chicken manure 4 kg/polybag and POC DI Grow 20 ml/l).
