SKRIPSI PENGARUH DOSIS PUPUK PHOSPHAT DAN DOLOMIT TERHADAP HASIL BUNCIS ( Phaseolus Vulgaris, L. )
ABSTRACT
The purpose of this experiment is to know abaut the influence of dosage phosphat fertilizer and dolomit to bush bean (Phaseolus vulgaris, L) Early bush variety. This experiment was caried out at Menggoro village, Tembarak district, Temanggung regency, from the and of June until September 1990. The soil type was brown Latosol with a pH 5,5 the altitude is 530 m above the sea level.
This experiment use the Randomized Complete Block Design (RCBD), arranged in factorial with two factors and tree replications.
The first factor TSP fertilizer dose consist of four levels.
P0 : 0 kg TSP/ha (Control) 0
P1: 90 kg TSP/ha
P2 : 180 kg TSP/ha
P3: 270 kg TSP/ha
The second factor Dolomit dose consist of three levels
D0 : 0 kg dolomit/ha
D1 : 200 kg dolomit/ha
D2 : 400 kg dolomit/ha
The result of the axperiment showed that the TSP fertilizer and dolomit non significan by all observation parameter. The heighest yield of treatment combination (P2D2) that is 89,475 kw/ha and the lowest yield of plant control that is 67,378 kw/ha.
