Using POC Azolla Mycrophylla and Urea Fertilizer: Lettuce Plant (Lactuca Sativa L) Context

The aim of the study was to obtain the best dose of POC Azolla microphylla in urea efficiency against the growth and production of lettuce. The study was conducted experimentally with non-factorial completely randomized design with 5 treatments and 4 replications each treatment consisting of 4 plants and 2 plants used as samples: A0 = Control (without treatment), A1 = POC treatment Azolla microphylla 30 ml l(-1 )+ Urea 2 g plant(-1), A2 = Treatment of POC Azolla microphylla 60 ml l(-1)+ Urea 1.5 g plant(-1), A3 = Treatment of POC Azolla microphylla 90 ml l + Urea l g plant(-1), A4 = POC treatment Azolla microphylla 120 ml l(-1) + Urea 0.5 g plant(-1). The results of the study were concluded; The combination of POC Azolla microphylla was able to streamline the administration of urea to stem diameter, number of leaves, fresh weight, consumption weight and dry weight of lettuce (Lactuca sativa L) and A4 treatment by giving POC Azolla microphylla 120 ml l(-1) which was the best for urea efficiency.
