Growth of Creeping Bentgrass by Application of Compound Fertilizer Containing Microbes

Abstract

ABSTRACT. Superintendents have been used microbial fertilizers to improve turfgrass growth and quality and to decrease turfgrass diseases in golf course. This study was conducted to investigate the effects of compound fertilizer containing microbe (MF) on the growth and quality of creeping bentgrass with turf color index (TCI), chlorophyll index (ChI), root length, turfgrass density, clipping yield and nutrient content. Treatments were designed as follows; non-fertilizer (NF), compound fertilizer (21-17-17; CF) as control, compound fertilizer (14-6-17) containing microbe. In pot experiment, TCI and ChI of creeping bentgrass in MF plot were similar to those in CF. But clipping dry weight of MF plot increased by 39.1% compared to that of CF plot. At field experiment applied with MF treatment, TCI, ChI, root length, and nutrient content and uptake of creeping bentgrass were similar to those with CF treatment, but turfgrass density with MF higher about 7.9-15.8% than with CF. These results indicated that the application of MF improved growth and quality of creeping bentgrass by enhancing clipping yield and shoot number.

“…국내에서는 이러한 유용 미생물 을 이용하여 작물재배에 이용할 수 있으며, 비료공정규격에서 는 토양미생물제제로 분류하고 있다. 해외에서는 완효성비료 에서 미생물이 함유되어 있는 비료도 있으나 [7] 국내의 비료공 정규격에서는 토양미생물제제로만 등록하도록 허용하고 있다. 토양미생물제제의 제형화는 액제, 수용제, 수화제, 캡슐제 등 비료를 이용하는 방법에 따라 다양한 형태가 있다 [8,9].…”

“…이 외에 도 부식산 처리는 잔디의 내건성이 증가하며 (Hunter and Anders, 2004) (Kweon et al, 2005;Lee et al, 2013;Kim, 2015). 그러나, 토양에 처리된 부식산은 토양개량제의 특성 상 쉽 게 분해되지 않는 휴민으로 되어 있어 수용성 부식산 함량은 매우 적다 (Lee et al, 2017 (Kim et al, 2016). (Vaughan, 1974;Cacco and Dell'Agnolla, 1984;Russo and Berlyn, 1990 (Kim et al, 2007;Kim et al, 2017…”

“…The nutrient content and uptake amount of turfgrass leaf in the creeping bentgrass after applying SMF in the pot experiment질과 엽록소 a+b 함량은 SMF 처리량에 따라 정의 상관성을 나타냈으나(Table 4, 5) 포장시험에서는 확인하기 어려웠다. 이 는 포트시험의 경우 예지 간격이 1개월로 비료 시비 후 잔디의 손실이 없으나 포장시험의 경우 주 2-4회 예지를 실시하여 잔 디가 손실되었기 때문으로 판단된다[28].Treatments were as follow. NF: non-fertilizer, control: compound fertilizer (N-P 2 O 5 -K 2 O=21-17-17; 14.3 g/m 2 ), SMFp-1 (Control+SMF 1 mL/m 2 ), SMFp-2 (Control+SMF 2 mL/m 2 ) and SMFp-3 (Control+SMF 4 mL/m 2 ).…”
