SKRIPSI PENGARUH PENGOLAHAN TANAH DAN WAKTU PEMUPUKAN NPK TERHADAP HASIL KACANG HIJAU (Phaseolus radiatus L)
ABSTRACT
The research about the effect of soil tillage and the fertilization time of NPK on the yield of mung bean (Pha - seolus radiatus L), has been conducted at development Cen tre Garden of Palawija Central Java, Soropadan Pringsurat district, Temanggung regency, since January 30th 1986 to May 8th 1986. Soil type is Latosol, the elevation 550 metres from level of the sea, with pH 4.9.
This research used Pactorial Design, arranger in the Randomized Complete Block Design (RCBD), consists of two faktors with three replication. Those faktors were:
1. Soil tillage
K1= Soil tillage 3 time
K2= Soil tillage 2 time
K3= 8011 tillage 1 time
2. Fertilisation time
P0= Without fertilisation
P1= Of fertilizer applied all on planted
P2= Of fertilizer applied all on flowerization
P3= Fertilizer applied a half on planted and a half applied on flowerization
The result of showed that soil tillage and fertiliza- tion time non significant effect on all parameter observed. With Duncan multiple range test 5% was significant effect on unfilled pods number per plant, the highest yield on K1P2 (1,81) the lowest ylord on K2P1 (0,95) the highest matter fresh weight on K. K3P2 (17,31 g) lowest on K1P3 (10, 64 g) and the highest matter dry weight on K3P2 (8,25 g) and the lowest on K2PO (5,87 g).
