Abstract

This research was carried out at the Experimental Garden of the Faculty of Agriculture, Asahan University in Kisaran Naga Village, Kisaran Timur District, Asahan Regency, North Sumatra Province with a topography of 23 m above sea level, temperatures between 20°C and 30°C, and relative humidity of 90%. This research was carried out between December 2022 and March 2023. This study aims to find out how the effect of giving laying hens feed pellets and npk 19:9:19 fertilizer has on the growth and production of cauliflower plants. The design used was a factorial Randomized Block Design (RBD), with 2 treatment factors: the first factor was: Pellet Feed Laying Hens (A) with 4 levels namely A0 = 0 g/plot (control), A1 = 24 g/plot, A2 = 48 g/plot, A3 = 72 g/plot. The second factor was the NPK 19:9:19 (N) fertilizer treatment with 3 levels, namely N0 = 0 g/plot (control), N1 = 19 g/plot and N2 = 38 g/plot. Giving laying hens feed pellets at a dose of 72 g/plot (A3), produced the best plant height of 26.80 cm, production per plant of 558.89 g and production per plot of 2.30 kg. Treatment of feed pellets for laying hens at a dose of 48 g/plot (A2) resulted in a flower diameter of 15.33 mm. Application of NPK 19:9:19 fertilizer at a dose of 38 g/plot (N2), produced the best plant height of 26.45 cm, flower diameter of 15,99 mm, production per plant of 519.17 g, and production per plot of 2 .23 kg. The interaction between the treatment of laying hen feed pellets and NPK 1:9:19 fertilizer had no significant effect on all observed variables. This shows that the factor of laying hen feed pellets and NPK 19:9:19 fertilizer together or individually can affect the growth of cauliflower plants.
