PERTUMBUHAN DAN PRODUKSI MICROGREENS PAKCOY PADA JENIS MEDIA TANAM DAN PUPUK ORGANIK CAIR URIN SAPI

This research aims to determine the effect of the type of planting media and the dose of cow urine liquid organic fertilizer on the growth of pak choy microgreens. This research was structured using a factorial Randomized Group Design (RAK). The first factor is that the planting media consists of 3 levels, namely: M1 (cocopeat), M2 (husk charcoal) and M3 (cocopeat+husk charcoal). The second factor is the dose of liquid organic fertilizer from cow urine consisting of 2 levels, namely a dose of 25 ml/L (D1), a dose of 50 ml/L (D2) and a control using water (D0). The parameters observed were the time when germination began (days), the time when cotyledons emerged (days), the time when the percentage of germination reached 100% (days) and the fresh weight (gr). The research results showed that the best medium for the emergence of sprouts was a medium consisting of a mixture of cocopeat and husk charcoal with a germination time of 1 day after sowing (HSS), the best medium for the emergence of cotyledons was husk charcoal, namely 2 HSS. Application of liquid organic fertilizer doses of 25 and 50 ml per liter resulted in a sprout percentage of 100% at HSS age. The use of liquid organic fertilizer is not recommended on cocopeat media. The use of cow urine doses of 25 ml and 50 ml is recommended for husk charcoal media and mixed media of husk charcoal and cocopeat.
