Abstract

This study was conducted to estimate effects of application of controlled release complex fertilizer with latex coated urea (LCU-complex) on growth and grain quality of rice under direct seeded on dry paddy (DS) and transplanted on flooding paddy (TP). Three types of latex coated urea different nitrogen (N) releasing were LCU40, LCU80 and LCU100. The time of N releasing of LCU formulations in water at both 20 and $30^{\circ}C$ was faster in the order of LCU40, LCU80, LCU blend (LCU40, LCU80 and LCU100 was mixed in ratio of 2:2:1), and LCU100. The number of tillers and dry matter weight were great in order of LCU-complex 100% > LCU-complex80% > urea and plant height was not significant. Grain yields at LCU-complex80% in both DS and TP plot were similar to those of urea application. N recovery of LCU-complex80% and 100% was improved 8 and 6% compared to that of conventional urea split application in DS plot and 9 and 4% in TP. Content of protein of grain at applied LCU-complex was less 0.8% and $0.1{\sim}0.7%$ than that of urea in DS and TP, respectively. Content of amylose and Mg/K ratio in rice grain was not significant. Consequently application of LCU-complex blended types of coated urea different N releasing can be reduced 20% of N without yield reduction and improved grain quality compared with urea application.

본 시험은 질소 용출 속도가 다른 3가지 피복요소가 포함된 완효성 복합비료를 관행 요소시비량의 80 및 100% 수준으로 시용하여 벼 건답직파 및 이앙재배에서 벼 생육, 수량 및 질소이용율을 알아보고 쌀의 품질에 미치는 영향을 조사하였다. 1. LCU의 제형별 $20^{\circ}C$ 및 $30^{\circ}C$에서 수중 용출 속도는 LCU40 > LCU80 > LCU혼합 > LCU100 순으로 빨랐다. 2. 벼 생육 및 수량은 건답직파 및 이앙재배 모두에서 LCU-복비100% > LCU-복비80% > 관행 순으로 높았다. 3. LCU-복비 시용에 의한 질소이용율은 요소시용에 비해 건답직파재배에서는 $4{\sim}7%$, 이앙재배에서는 $11{\sim}13%$ 향상되었으며, 표준시비량의 20%를 감비한 LCU-복비 80% 시용이 단위시비질소의 생산성이 가장 높았다. 4. 단백질 함량은 건답직파 및 이앙재배의 무질소구에서 6.3 및 6.6%로 가장 낮았고, 비료 처리간에는 LCU-복비 80% 시용구에서 각각 6.5 및 6.7%로 관행 요소시용 7.3 및 7.4%에 비해 낮았다. 5. 아밀로즈 함량 및 Mg/K 비는 모든 처리간에 유의성이 없었다. 또한 쌀의 호화특성 중 최고점도 및 강하점도는 LCU-복비 시용에 의해 다소 높았지만 통계적인 유의성은 없었다.
