Effect of soil tillage methods and cattle fertilizer of cow on increasing sweet corn (Zea mays saccharate sturt) production

Abstract

Abstract Sweet corn production is relatively low in Indonesia. To increase production one of the efforts that can be done is to improve the method of soil tillage and by giving doses of cattle fertilizers. The study was conducted in Asam Kumbang Village, North Sumatra Province, Indonesia. The research design used was the Splite Plot Design. Treatment factors consist of factors of soil treatment method and factor of cattle fertilizers. The factor of the soil treatment method consists of 3 levels: T 1 = No soil tillage. T 2 = soil tillage one time. T 3 = soil tillage two times. The factor of cattle fertilizers consists of 4 levels: K 1 = Inorganic fertilizer/ha (200 kg Urea.100 kg TSP, 100 kg KCl). K 2 = 10 tons of cattle fertilizers/ha. K 3 = 20 tons of cattle fertilizers/ha. K 4 = 30 tons of cattle fertilizers/ha. The results showed that the highest production of cobs for the treatment of soil tillage methods is found in T 2 treatment (soil tillage onetime) with a production level of 8820.19g/plot (26.25tons/ha). For the treatment of cattle fertilizer, the highest cob production was obtained in K4 treatment (dose of 30 tons of cattle fertilizers/ha) with the production level reached 10154.67g per plot (30.22 tons/ha).
