EFFECT OF DUCK MANURE AND NPK FERTILIZER ON GROWTH AND YIELD OF CABBAGE FLOWERS IN ALLUVIAL SOIL

Abstract

The purpose of this study was to determine the best interaction between duck manure and NPK on the growth and yield     of flower cabbage on alluvial soil. This study used a factorial design with a Completely Randomized Design Pattern. The treatment consisted of two factors, namely the dose of duck manure (P) and NPK (N) fertilizer with 3 levels of duck manure treatment and 3 levels  of NPK (N) fertilizer treatment, three replications and 4 samples witha total of 108 plants. The treatment in question is as follows: The first factor is the doseof duck manure consisting of 3 levels, namely: p1 = 10 tons/ha equivalent to 200 g/polybag, p2 = 20 tons/ha equivalent to 400 g/polybag, p3 = 30 ton/ha is equivalentto 600 g/polybag. The second factor is the dose of NPK fertilizer consisting of 3 levels,namely:    n1= 300 kg NPK/ha is equivalent to 6 g/plant, n2 = 400 kg NPK/ha is equivalent to 8 g/plant, n3 = 500 kg NPK/ha is equivalent to 10 g/plant. Theinteraction of 30 ton/ha duck manure and 400 kg/ha NPK fertilizer showed the best growth and yield of flower     cabbage on alluvial soil, but with the same dose of duck manure and 300 kg/ha NPK fertilizer, it was equivalent to 6 g/polybag. already good for the growth and yield of flower cabbage on alluvial soil.
