Effect doses level of vermigot fertilizer on the chemical and biological characteristics of Inceptisol and Maize (Zea mays L.) production

Abstract

Vermigot is an organic fertilizer produced from a combination of vermicompost and BSF compost. By applying Vermigot fertilizer to maize on Inceptisol, it’s hoped that it can help increase maize production and improve the chemical-biological characteristics of Inceptisol. This research aims to determine the effect of various doses of Vermigot fertilizer on the chemical and biological properties of Inceptisol soil and maize production This study used a Non Factorial Randomized Complete Block Design (RCBD), including: V0 = 0 gram, V1 = 100 gram, V2 = 200 gram and V3 = 300 gram with 6 replications to obtain 24 treatments. Parameters observed included maize production: shoot dry weight (g), root dry weight (g), corncob weight (g), final plant height of the vegetative phase (cm) and stem diameter at the end of the vegetative phase (mm). Inceptisol soil chemical-biological properties: pH soil, C-Organic (%), N-Total (%), Available-P (ppm) and microbial population (CFU/g). The maize variety used was Pioneer 35. The results showed that the application of various doses of Vermigot had a significant effect on the chemical of the Inceptisol, pH soil with the highest treatment at the V3 (300 g) of 6.80 (neutral) and the available-P of the soil with the best treatment V3 (300 g) of 31.90 ppm. Microbial population had no significant effect and maize production (Zea mays L.) had a significant effect, the weight of corn cobs with the best treatment V3 (300 g) of 250.56 gram.
