Abstract

The aims of this research was to determine the impact of chicken manure and P fertilizer on the development and production of cauliflower. This research was done from February to April 2023 in Pakis, Magelang This study used a completely randomized design (CRD) which includes 2 factors. Factor A uses chicken manure with a measurement of 3 types, such as 200 g, 400 g, 600 g. Factor B uses P fertilizer with a dose of 3 types, such as 20 g, 30 g, 40 g.
