Nanotechnology is a science that deals with objects measuring 1–100 nm that are
different from their original properties. Nano technology fertilizers are more reactive and
on target with minimum use. Nanotechnology fertilizers can be utilized as slow release
fertilizers, allowing for optimum fertilizer uptake by plants. Because of the holes that
can store nitrogen fertilizers, zeolite and bovine bone can be utilized as fertilizer coatings.
This study was conducted at Universitas Gadjah Mada's Faculty of Agriculture. The
research method used was a 2X5 factorial completely randomized design (CRD) with
each treatment being repeated 3 times so that the total polybags used were 30 polybags.
The first factor was the type of coating material for urea, nano zeolite, and nano bovine
bone. The second factor consisted of a dose of coated urea fertilizer with five kinds of
dose treatments, which were 0, 100, 200, 300, and 400 kg.ha⁻¹. ANOVA was used to
analyze parameter data, followed by testing using the DMRT (Duncan's Multiple Range
Test). When compared to nano bovine bone, the effectiveness of N removal with nano
zeolite generated the best results as a slow release fertilizer on N uptake. The best N
fertilization dose with nano zeolite coating was 200 kg.ha⁻¹, which increased corn plant
growth by producing the highest plant height (167.17 cm) and N uptake of 1.6 g/plant.
This research can be a recommendation for more effective and efficient Nitrogen
fertilization for corn farmers |
