SKRIPSI PENGARUH DOSIS HERBISIDA METRIBUZIN TERHADAP PODUKSI BEBERAPA VARIETAS KEDELAI (Glycine max (L)Merr)
SUMMARY
This experiment had been conducted from May 1967 until August 1987, at Dlangu village, Butuh district, Purworejo regency. The soil type in Regosol, with an altitude of 20 m above sea level. The pH = 6,0.
The purpose of the experiment was to study the effect of Metribusin dose for neveral production of soybean variety (Glycing max (L) Merr).
The research used was Split Plot Design with arranged In Randomized Complete Blok Design, with variety as main plot and herbicide dose as nub plot. The number of treatment combination were fifteen and each treatment with three replications.
Main plot: Variety (V) consisted of
V1: Lokon variety
V2: Galunggung variety
V3: Guntur variety
Sub plot: Herbicide dose (D) Consisted of
D0 : Metribuzin dose 0,0 kg/ha as control
D1 : Metribuzin dose 0,5 kg/ha
D2 : Metribuzin dose 1,0 kg/ha
D3 : Metribuzin dose 1,5 kg/ha
D4 : Metribuzin dose 2,0 kg/ha 4
The observation include on height of plant, fresh weight of straw, number of pods, number of unfilled pods, number of filled pods, dry weight of straw, weight of dry seed, weight of 100 seed and harvest index. It is reported from this research that:
The herbicide dose height significanly affect on height of plant, number of pods, number of filled pode and weight of dry straw. But not significantly affent on fresh straw, number of unfilled poda, weight of 100 seed and harvest index.
The variety level height significantly affect on harharvest index and significantly affect on height of plant, fresh weight of straw, weight of dry straw. But not algni- ficantly affect on number of pods, number of filled pode, number of unfilled poda and weight of 100 seed.
The interaction on the number of pods, number of filled pode and weight of seed. The highest reached of Vi (Lokon variety) by Dy (1.5 kg/ha), V₂ (Galunggung variety) by D₂ (1,0 kg/ha) and Vs (Guntur variety) by 22 (1.0 kg/ha).
