SKRIPSI PENGARUH JARAK TANAM DAN DOSIS PUPUK FOSFAT DAN KALIUM TERHADAP HASIL BUNCIS TEGAK ( Phaseolus vulgaris, L )
ABSTRACT
The experiment of effect interval to plant and dose of P and K on the yield of beans (Phaseolus vulgaris, L). had been carried out in September 10 until November 17 of 1996. This experiment was carried out in Kedungsari vil- lage, Magelang Utara district, soil pH 6.0 with an alti- tude of 350 m above sea level.
The experiment is to search the best effect of inter- val to plant adn dose of P and K on the yield of beans. The experiment was faktorial with Randomized Complet- ly Block Design (RBCD), consist of 2 factor and 3 replica- tion. Factor I: interval to plant (J), that is J₁: 20 x 30 cm, J2: 20 x 40 cm, J3: 20 x 50 cm. Factor II: dose of P and K (P), that is Po: 0 kg/ha, P1 TSP 90 kg/ha: : ZK 86kg/ha, P2: 180 kg/ha: ZK 172 kg/ha,kg/ha. P3: 270 kg/ha: ZK 258
The result of the experiment showed that interval to plant increased could to the height of plant, number of pods, weight of pods the fresh weight of straw, the dry weight of straw, but can't increased lenght of pods.
The dose of P and K fertilizer showed increased could to all parameters.
Ther was no interaction effect between interval to plant and dose of P and K to all parameters.
The effect dose P and K (PO, P1, P2, P3) increased was regression, and P3 (TSP 270 kg/ha; ZK 258 kg/ha) gave better yield that is 115.300 gram per plant.
