The Effects of Slow-Release Fertilizer Using Wastepaper on Growth of Chinese Cabbage

ABSTRACT

In order to raise awareness about environmental protection, people are paying more attention now-a-days in reusing wastepaper. As a result, most countries in the world have already made significant progress related to wastepaper recycling technology. This study was conducted to investigate the effects of slow-release fertilizer (SRF) on Chinese cabbage production. Wastepaper was deinked and the SRF was produced from fertilizer impregnated wastepaper. A field experiment was conducted to evaluate the effects of a general fertilizer along with compost and SRF without compost on the cabbage production. The leaf length, total chlorophyll content, and fresh weight of head of cabbage were significantly improved through the application of the SRF than general fertilizer. Some agronomic and chemical components were also observed and found significant differences between the two fertilizers. In addition, pH and organic matter contents were higher in the soils fertilized with the SRF. Our results show that though the amount of SRF applied was larger compared to that of general chemical fertilizer, cabbage production was increased due to the application of SRF.
