SKRIPSI PENGARUH DOSIS DAN KEDALAMAN PEMBERIAN PUPUK UREA BRIKET TERHADAP HASIL TANAMAN PADI (Oryza sativa L.) VARIETAS IR 66 PADA TANAH LATOSOL
ABSTRACT
The objective of this experiment is to know the in- fluence of dose and depth fertilized urea briket on the- yield of rice plant. The experiment was carried out fron January, 1993 until April, 1993 in Boko vilange, Hertoyu- dan district, the regency of Hagelang, on the Latosol so- 11, altitude is 320 metres with på 6.5.
Metodologi of this exeperiment in the Faktorial - thod based on Randomized Complately Block Design (ACHD), consist of a factors with 3 replications. The first fac tor is a with urea briket dose and the two factor i8 1 with urea briket depth. There wore 12 treatment combinat ons.
Factor I. Urea briket done (D) to consist of
D0 : Dose D kg/ha
D1 : Dose 100 kg/ha
D2 : Doas 200 kg/ha
D3 : Dose 300 kg/ha
Factor II. Urea briket depth (K) to consist of
K1 : Depth 5 αι
K2 : Depth 10 cm
K3 : Depth 15
The result of experiment showed that
1. Urea briket dose treatment was vary significant to the all of parametres.
2. Urea briket depth treatment was very significant to- the number of total tillers, the number of productive tillers, the number of grain per spire and the weight of 1000 dry grain, significant to result of dry unimag ed per plot. But ono significant to the Lenght of sp re, fresh weight of straw and dry weight of straws.
3. Interaction between dose and depth urea briket fertilg god was very significant to the number of productive tillers and significant to the mumber of grain por s
re and dry weight of strawa. 4. The height result of dry unhusked per plot was gained by of 2 2,30 kg/plot or 5,95 ton/ha) and the lowest 22 yield (1,22 kg/plot or 3,05 ton/ha).
