| Summary: | Filter cake can be used in agriculture as soil corrective or fertilizer, but its potential is unexplored until now. This research, carried out at Chitaraque/Boyacá, aimed to evaluate the effect of different doses of soil corrective (fresh filter cake), compared with a commercial fertilizer and maize without treatments. Each experimental unit (EU) was composed of 96 plants for a total of 2,304 for the experiment. The physiological variables analyzed were measured at harvest time, selecting eight plants of the center of each EU, and were: kernel number per cob, weight of 100 kernels, plant height (cm), stalk diameter at 50 and 100cm of plant height, leaf area (cm2), fresh matter (g) and dry matter (g). The higher kernel production was obtained with the application 7.5t.ha-1 of fresh filter cake. The doses of 5.8t.ha-1 resulted in the highest production of dry kernels and the greatest height was founded with 15t.ha-1 of fresh filter cake; the same dosage originated the thickest diameter. The greatest amount of foliage and fresh matter were found with 12.5t.ha-1. Dry matter, on the other hand, didn’t show statistically significant differences between the various doses of fresh filter cake. The use of fresh filter cake showed higher fresh mass and the dose of 8t.ha-1increased the kernel number, since the application of this organic amendment helped to improve corn yield and can supply, in this case, the chemical fertilization. |
