Abstract

Research was conducted to evaluate the effect plough depth and the dosage of organic fertilizer on the growth and spear production of asparagus. The research was conducted in Bengkulu using PMK soil which is predominant in the province. Two kind of treatment, ie. The depth of plough (range from 20 to 50 cm depth) was treated in split plot design as the main plot and the dosage of organic fertilizer (range from 0 to 7 tons per hectare) as the sub plot. Asparagus cultivar UC157, originated from California, was used to evaluate the effect of treatment on the growth and production.. The preliminary result shows that the growth of aparagus in term of shoot height and number of shoot were not effectively affected by the various dept of plough. Regular measurement for 16 weeks also confirm that the dept of plough alone did not affect the early growth of asparagus plant. In contrast, organic fertilizer (sheep feces) significantly affected the growth of asparagus, either its height of number of shoot. This finding suggests that the improvement in physical properties of the soil due to the organic fertilizer incorporation occurred and directly affected the growth of asparagus
