SKRIPSI PENGARUH DOSIS PUPUK INRA PADA BEBERAPA JENIS TANAH TERHADAP HASIL TANAMAN SELEDRI (Apium graveolens, L.)
ABSTRACT
The aim of this research was to know about the effect of INRA fertilizer dose and soil kind on the yield at plant of celery (Apium graveolens, L.). This research was carried out from September, 2000 untill December, 2000 at Paponan village, Parakan District, Temanggung Regency with an altitude 900 meters above sea level. Kind of soil is latosol with pH 6,2 and regosol pH 6,5.
The research used the factorial method with principle design, it's Randomized Complete Design (RCD) consisting of two factors and three replications with analysis of variance and then LSD test 1% level and orthogonal polinomial test. First factor, soil kind J) consist of two level, they are Latosol and Regosol soil. Second factor, INRA fertilizer dose, consist of five level, they are 0, 38, 77, 115 and 154 g/plant.
The result of research shows that soil kind are very effected height of plant, number of leaves, fresh weight of economical yield, fresh weight of biological yield, dry weight of biological yield and harvest index. INRA fertilizer dose are very effected height of plant, number of leaves, fresh weight of economical yield, fresh weight of biological yield, dry weight of biological yield and harvest index. The interaction at fresh weight of economical yield, fresh weight of biological yield, dry weight of biological yield and harvest index. The best yaeld of celery (Apium graveolens, L.) obtained at 95 g/plant or 12,67 ton/ha INRA fertilizer dose at regosol.
