Abstract
Sweet corn is one of the most popular commodities in West Papua. The culture of roasting, grilling and boiling corn as snacks is often found along the main road Continuous production is needed to meet the tastes of these consumers. This study was aimed at determining the production and chemical quality of sweet corn using single fertilizer combination (SFC) on dry land in West Papua. Research method used a completely randomized design experiment with 5 treatments and 3 replications. The treatments tested were, without fertilization (P0), SFC with a concentration of P1 (14,4g/plant)- P2 (15,12g/plant)- P3 (15,84g/plant) and P4 (16,56g/plant). Variables observed were weight of corn cobs, length of the corn cobs, diameter of the corn cobs, pH, water content, ash content and fat content. The data obtained were analyzed using analysis of variance (ANOVA) and continued with the Honest Significant Difference Test (HSD). Results showed that different concentrations of SFC did not give a significant difference (P>0.05) on pH, water content, ash content and fat content.- gave a very significant difference (P<0.01) on weight, cob length and diameter of sweet corn cobs. The average weights (g) for treatments P0, P1, P2, P3, and P4 were 51.39- 115.40- 133.06- 177.89 and 199.13 respectively. Cob length (mm) 78.45- 107.37- 113.92- 131.54 and 141.02. Cob diameter (mm) 24.56- 31.22- 34.29- 36.21 and 37.55. pH value 5,47- 5,37- 5,41- 5,40 and 5,38. Moisture content (%) 60.41- 60.75- 60.29- 60.08 and 60.08. Ash content (%) 1.95- 2.07- 2.05- 1.96 and 1.92. Fat content (%) 0,62- 0,53- 0,43- 0,52 and 0,40. The conclusion of this study was that different concentrations of SFC did not give a different effect on pH, water content, ash content and fat content and gave a very significant difference in effect on weight, cob length and diameter of sweet corn cobs.
