SKRIPSI PENGARUH DOSIS PUPUK P TERHADAP HASIL BEBERAPA VARIETAS TANAMAN KACANG PANJANG (Vigna sinensis, L.)
ABSTRACT
The research concerning "The Effect of Dose Fertilizer P to Some Varieties a Long Nourishing Bean (Vigna sinensis, 1)" it has carried out during the September up to January 1993, at Banjarnegoro, Mertoyudan, the Regency Magelang, Central Java, the soil type was latosol, pH 6, 0, the altitute of 375 m above see level.
The research used split plot design method with the basic design Randomized Completely Block Design (RCBD), it consist of 2 factors, the method was replicated three times and finally tested by Duncan's Multiple Range Test 5%.
The first factor (main plot) was the kinds of variety, it consist of 3 levels, they are Lokal variety, Usus Hijau variety and Usus Putih variety. The second factor (sub plot) was the dose O kg/ha, dose 75 kg/ha, dose 150 kg/ha and dose 225 kg/ha.
The research result was showed that TSP fertilizer dose highly significant different on parameters the flowering time, the length of pods, the number of seeds per pods, the weight of pods per plant, the weight of pods per plot and the volume of roots and not significant different on parameter the number of pods per plant.
The kinds of variety highly significant different on parameters the length of pods, the number of pods per plant,
the weight of pods per plant, the weight of pods per plot and the volume of root s, and not significant different on parameters the flowering time and the number of seeds per pods.
There are interaction between the kind of variety and TSP dose on the parameters the length of pods, the number of
seeds per pods, the weight of pods per plant, the weight of pods per plot and the volume of roots.
The application of variety Usus Hijau with 150 kg/ha TSP fertilizer dose will be give the best yield on the weight of pods per plant that is 479,567 gram.
