Abstract

ABSTRACT The Effect of Combination of Organonitrofos and Inorganic Fertilizers on Soil Respiration in Taman Bogo Ultisol Soil planted with Sweet Corn (Z. mays [L.] Saccharata Sturt). This study end to determine the effect of combination between Organonitrofos and inorganic fertilizers on soil respiration on Taman Bogo ultisol soil planted with sweet corn (Z. mays [L.] Saccharata Sturt). This study used a randomized block design (RBD) with 11 treatments and repeated three times. The data obtained were analyzed by analysis of variance. The mean mean of the data was tested by means of the Orthogonal Contrast test at the level of 1% and 5%. The relationship between organic C, total N, soil pH, and soil moisture content with soil respiration was tested by correlation test. The results showed that the combination of organonitrofos and inorganic fertilizers as well as single fertilizer treatment has the highest soil respiration rate compared on control in all observation except 15 DAS. The combination of 100% Organonitrofos and 100% inorganic fertilizers has the highest and increase soil respiration rate compared to other combinations at all observation times. The result showed that there was a significant correlation between organic C and total N on soil respiration. Keywords: Ultisol soil, Organonitofos fertilizer, inorganic fertilizers, soil respiration.
