SKRIPSI PENGARUH SAAT PEMUPUKAN DAN DOSIS PUPUK NPK TERHADAP HASIL KACANG MERAH (Phaseolus vulgaris L.)
ABSTRACT
The experiment of the effect of time of application and donage NPK 15-15-15 to the yield of Kidney bean (Phaseolus vulgaris L.) was carried out at Kedungsari Village, Sub District North Magelang, Magelang City, from 28 Mei 1991 un- til 4 Agustus 1991. The soil type was Latosol, the soil pil 6,7 with an altitude of 380 metres.
The experiment design used was Split Plot Design (SPD) composed by Randomized Complet Block Design (RCBD), consisted of two treatment factor by three replications.
1. Factor of time of application (3) as main plot:
S1: of time planting
S2: 10 days after planting
S3: 20 days after planting
2. Factor of dosage of application (D) as sub plot:
Do: Control
D1: 100 kg/ha NPK 15-15-15
D2: 200 kg/ha NPK 15-15-15
D3: 300 kg/ha NPK 15-15-15
The result of experiment showed that:
1. The factor of time of application was non significant to the all observations.
2. The factor of done NPK was significant to the number of unfilled pode and the weight of 100 seeds and very
significant to the height of plant, number of the filled pods, the fresh weight of straw, the dry weight of straw,
weight of fresh seeds and weight of dry seeds.
3. The factor between was not interaction to all observations.
4. The heighest result from the weight of dry seeds per plant was 31,11 & from treatment S₂D₂ and the lowest
15,46 g from treatment S1 D0.
