Abstract
The research on conservation tillage system is important, because it can contribute about sustainable agriculture system in Indonesia. The objectives of the research were: to find out the NPK absorption and production of corn variety DK 8652 on conservation tillage system at Entisol Klaten. The research was conducted at Ketandan, Klaten district of Entisol rice field on dry season it has been rice harvesting. This experiment used randomized completely block design with split-plot treatment by 3x5x3. In field experiment, three conservation tillage system (No-tillage, minimum tillage and conventional tillage) as main plot were prepared with planting corn (Zea mays) variety DK 8652 and were fertilized with five dosages of urea 0, 200, 300, 400, 500 kg/ha equivalent to 0, 92, 138, 184, 230 kg N/ha respectively as sub-plot; and were added with 150 kg/ha SP 36, 100 kg/ha KCl as base fertilizer. The results of this research showed that N absorption the highest achieved by OTM on dosage urea 200 and 300 kg/ha followed by TOT and OTS. The P absorption was the highest achieved by OTS on dosage urea 400 kg/ha. The K absorption was the highest achieved by TOT on dosage urea 200 kg/ha. Corn production of all conservation tillage system was the highest on dosage urea 400 kg/ha, an indication of the NPK absorption by corn variety DK 8652 was more effective on dosage urea 400 kg/ha.
