PENGARUH PEMBERIAN PUPUK KANDANG AYAM DAN PUPUK UREA TERHADAP PERTUMBUHAN DAN PRODUKSI TANAMAN KAILAN ( Brassica oleraceae L )

Abstract

The rised aims to investigate the influence of chicken  manure and urea fertilizer on growth and yield of kailan (Brassica oleraceae L ) varietas acephala DC.

The experiment was conducted using randomized Block Design 9 RBD) with 4 x 4 factorial experiment consisted of 3 ( three) replications. The first in chicken  manure four levels : p_{0 :} 0 g plot ^-1(control), p₁: 500 g plot^-1 equivalent to 500 g ha^-1, p₂ : 1000 g plot^-1 equivalent of 1 ton ha^-1 and p₃ : 1500 g plot^-1 equivalent to 1.5 tons ha^-1. Urea Manure 4 second level : n₀; 0 plot^-1(control), n₁: 2,5 g plot^-1 equivalent to 25 kg ha^-1, n₂: 5 g plot^-1 equivalent to 50 kg ha^-1 and n₃ : 7,5 g plot^-1 equivalent to 75 kg ha^-1.

                The result showed : (1) that chiken manure application significantly affected plant growth and production, except for plant height age of 10 days, p₃ treatment dose ( 1500 g plot^-1) showed the lowest weight of plant per hectare of 8,02 tons ha^-1, (2) The results showed that administration of urea significantly affected growth and yield, plant heigt except age 10 and 20 days and the average number of leat age 10 days, n₃  treatmant with a dose (7,5 plot^-1) showed the highest weight of plants per hectare , 15,48 tons ha^-1, n₀ treatment (0 g plot^-1) showed the lowest weight of plants per hectare, 11,57 tons ha^-1 and (3). Interaction of chicken manure and urea fertilizers provide a very real effect on all parameters, but did  not significantly affect plant height average age of 10 and 20 days and the average number of leat age 10 days. Interaction p₃n₃ showed the greatest weight of plant per hectare 22.70 tons ha^-1, whereas p₀n₀  showed the smallest weight of plant per hectare of 6,45 tons ha^-1.
