Abstract:
Utilization of agricultural waste as organic fertilizer has the potential to increase soil fertility and
increase nutrient availability. The application of inorganic fertilizer is intended to balanced the
availability of nutrients and increase the productivity of corn plants. The purpose of this study
was to determine the effect and interaction between various organic fertilizers with inorganic
fertilizers to increase C-organic, plant nitrogen, chlorophyll, growth and yield of corn (Zea mays)
Bisi-2 variety on Inceptisols soil. The research was conducted from July 2020 to January 2021 in
the experimental screen house at Ciparanje, Agriculture Faculty, Universitas Padjadjaran,
Jatinangor, West Java, 724 meters above the sea level. This research design used a randomized
block design factorial with 16 treatments and three replicates. The first factor was the type of
organic fertilizer of four levels: without organic fertilizer (control), 10ton ha-1 of rice straw,
sugarcane bagasse, and oil palm empty fruit bunches (OPEFB) compost. The second factor was
the dosage of inorganic fertilizers of four levels: without inorganic fertilizer (control), 50%, 75%
and 100% of dose recommendation inorganic fertilizer. The results showed that no interaction
between organic fertilizers and inorganic fertilizers against all the parameters. The effect of the
OPEFB 10 ton ha-1 treatment was the best treatment on the cob weight without husks 113.86
g/plant. The application of 100% inorganic fertilizer was not difference with 50% inonganic
fertilizer that produced cob weight without husks 114.63 g/plant. |
