Abstract
This study was conducted to evaluate the effect of developed SCB(DSCB) produced by adding N, P and K to SCB liquid fertilizer on the growth of creeping bentgrass. Fertilizer treatments were designed as follows; non-fertilizer (NF), control (CF; chemical fertilizer), 100 DSCB (250 $ml{\cdot}m^{-2}$DSCB), 80DSCB (200 $ml{\cdot}m^{-2}$DSCB) and CF+SCB (CF+250 $ml{\cdot}m^{-2}$SCB). Every treatment was arranged in a randomized complete block design with three replications. In creeping bentgrass, turf color index, chlorophyll index, dry weight, shoot number and nutrient content were measured. The results were as follows; Chemical properties of soil was hardly affected by DSCB and SCB applications. Turf color index and chlorophyll index in DSCB and SCB treatment were increased by 2~3% and 14~19% than those in NF, respectively, and similar to those of CF treatment. As applied to DSCB and SCB, shoot number was increased by 7%, 21%, 36% in 100 DSCB, 80 DSCB and CF+SCB than NF, respectively, and by 19% in CF+SCB than in CF. Supplying DSCB and SCB increased dry weight of creeping bentgrass, compared to CF treatment. Compared with CF, nitrogen and P content in tissue was increased in CF+SCB and in 80DSCB, respectively. These results suggested that applications of DSCB and SCB promoted turf quality and growth of creeping bentgrass by enhancing N and P uptake and shoot number.
