SKRIPSI PENGARUH JUMLAH TANAMAN PER LUBANG DAN DOSIS PUPUK TSP TERHADAP HASIL KACANG TANAH (Arachis hypogeae L.) Var. Gajah
ABSTRACT
The research entitled "THE INFLUENCE OF NUMBER OF PLANTS IN EACH HOLE AND TSP DOSAGE ON YIELD OF PEANUT Arachia hypogaea L.) of Gajah variety. The carried at from June 26, 1990 until October 6, 1990. The carried out at Kedungsari village, North Magelang, Magelang Regency, Central Java, The land of Latonol soil type, with a pH 6,0 and with an altitude of 380 meters.
The research was used factorial experiment method with Randomized Completely Block Design (RCBD), which it two treatment factors and three replications. The first factor: The number of plants in each hole of three levels: 71 (one plant in each hole) Ta (two plants in esch hole), Ts (three plants in each hole). Second factor: the dosage of fertiliser used was four levels Do (non TSF fertiliper), D1 (50 kg/ha TSP), D2 (75 kg/ha TSP), D3 (100 kg/ha TSP).
The research indicated that the treatment of plants in each hole has a significant in influence upon the height of plint, the mumber of branchen, the fresh weight of filled pod, the fresh weight of plant, the dry weight of plant. The average with yield observed heighent two planta in each hole (T2) and lower yield one plant in each hole (71).
The TSP donage of fertilizer wan significant influence upon the fresh weight of filled pod, the weight of dry filled pod. Non significant to the height plant, number of branches, the number of filled pods, the number of uni filled pods, the fresh, weight of plant, the dry weight of plant, the weight of dry seeds, the dry of 100 seeds. The average with yield observed hel ghest dosage 75 kg/ha (2) an and lowers
yield Do Do (non TSP fertilizer). The combination of treatment of two planta in each hole and donage 75 kg TSP/ha (T2D2) gave of heighest yield 23,22 gram/hole or 1114,56 gram/plot. And the treatment one planta In onch hole and non TSP fertilizer (TTO) lowerat yield 15,03 grm/hole or 720gram/plot.
The all the treatment combination of research non intraction on observation all parameters.
