SKRIPSI PENGARUH PUPUK KANDANG DAN DEKAMON TERHADAP HASIL LOBAK PUTIH (Rhaphanus sativus varietas Hortensis)
ABSTRACT
The research of the effect of dose of farm manure and concentration of dekamon on the yield of horse radish (Rhaphanus sativus L. Hortensjs Backer variety), hgd been carried out since September, 1st until Nopember, 9th , 1992 at Pucanganom village, Srumbung sub distric, Magelang district,
Central-Java province, on the altitude 501 m sea level, temperatur 26 c, and regosol vulcan soil type with pH 6.5.
The purpose of the experiment is to find out the dose of cow farm manure for the best yield, and Natrium Nitrofenol (dekamon) cocentration for the best yield and their in teraction.
The design of the experiment was arranged by Randomized
Complete Block Design (RCBD), using two treatment and three replication. The first treatment is dose of cow farm manure ( D) :
D0 = no treatment
D1 = 10 tons/ha
D2 = 20 tons/ha
D3 = 40 tons/ha
The second treatment, the concentration of Dekamon (K)
K0 = water sprayed
K1 = 1 cc/1 liter water
K2 = 2 cc/1 liter water
K3 = 3 cc/1 liter water
The observation including the leaves number, fresh biomass, the root diameter, the root length and the root weight.
For the best yield can used the 20 tons per hectare and with 1 cc per liter water dekamon and the 40 tons per hectare
and with 2 cc per liter water dekamon but their interaction was not significance therefor could we used one anather factors that was the cow farm manure 20 tons per hectare and 40 tons per hectare or 1 cc per liter water dekamon and 2 cc per liter water dekamon.
