SKRIPSI PENGARUH DOSIS KAPUR DOLOMIT DAN PUPUK P PADA TANAH GAMBUT TERHADAP HASIL KEDELAI (Glycine max (L) Merril)
ABSTRACT
The research concerning the effect Dolomite dose and P fertilizer at Peat soil for the yield of Soybean (Glycine max (L) Merrill.) aim to know the effect Dolomite dose and P fertilizer at Peat soil for the Yield of soybean growth.
The research was done at the plastic house at Kedungsari Village, North Magelang District, Magelang Regency. Altitude 380 M from sea level. The research begun on August 4th. - october 22th. 1992.
Research Method was using Factorial method with bottom design it's Completely Randomized Design (CRD) consist of 2 factors. It's Dolomite dose and P fertilizer, 3 replications.
Factor I : Dolomite dose (D) consist of 4 levels it's:
DO: 0 ton/ha
D1: 1,25 tons/ha
D2: 2,50 tons/ha
D3: 3,75 tons/ha
Factor II: P fertilizer (P) consist of 3 levels it`s:
P1: 40kgs/ha P205
P2: 80kgs/ha P205
P3: 120 kgs/ha P205
The result showed that treatment of Dolomit dose very significant effect for age of flowering, dry crown filled pod give numbers unfilled pod, fresh crown weight, weight, Ages of yield and significant to numbers but no significant for plant height and tissue analisyst.
P fertilizer give significant effect for age of flowering, ages of yield but not significant to plant height, numbers of filled pod, numbers unfilled pod, fresh crown weight, dry crown weight, weight of 100 seeds and tissue analisyst.
The highest yield of combination treatment (D2P3) that's Dolomite dose 2.5 tons/ha and P fertilizer 120 kgs/ha P205.
It wasn't interaction between Dolomite dose and P fertilizer for all observation parameters.
