SKRIPSI PENGARUH KONSENTRASI KNO3 (KALIUM NETRAT) DAN KONSENTRASI Ca3(PO4)2 (TRIKALSIUM POSPAT) PADA BUDIDAYA HIDROPONIK TERHADAP PERTUMBUHAN DAN PERKEMBANGAN TANAMAN BROKOLI ( Brassica oleracea var. Botrytis L. Subvar. Cymosa Lamm )
ABSTRACT
The experiment of effect of kalium nitrat consentration and tricalcium fosfat consentration for hidroponic system on the growth and flowering of sprouting broccoli, was carried out since September 20 until November 20, 1995 at Tampingan, Tegalrejo, Magelang. With an altitude of 390 m above of the sea, air damp of mean 70 percentage.
The purpose of this experiment ent is to know the effect of kalium nitrat consentration and tricalcium fosfat consentra- tion for hidroponic system on the growth and flowering of sprouting broccoli, Green King No 2 (559) variety.
The experiment was arranged of Faktorial in Completely Randomized Desgn (CRD), to consist of two factor treatment and three replication. Factor 1 (Kalium nitrat consentration) to consist of 3 level: 400 ppm (K), 700 ppm (K₂) and 1000 ppm (K₂). Factor 2 (tricalcium fosfat sentration) to con- sist of 3 level: 200 ppm (C₁), 400 ppm (C₂) and 600 ppm (C3).
The result of experiment showed that?
1. Kalium nitrat consentration gave a high significant effect for parametres of the height of plant, the lenght of root,
the numbers of shaped leafas, diametre of the stem end, leaf wide of age for 20 days, leaf wide of age for 40
days, leaf wide of age for 60 days, the fresh weight of straw and dry weight of straw.
2. Tricalcium fosfat consentration gave a high significant for the height of plant, leaf wide of age for 20 days, leaf
wide of age for 40 days, leaf wide of age for 60 days, the fresh weight of straw and dry weight of straw.
3. Interaction of treatment showed that height of plant and fresh weight of straw.
