조숙 옥수수에 의한 사료작물 작부체계 구성 II. 조숙 옥수수의 사료생산성에 미치는 만파와 밀식효과
Application of Early-maturing Corn to Cropping System of Forage Crop II. Effects of Late Sowing and Dense Planting of Early-maturing Corn on Forage Productivity
초록
조숙옥수수를 포함한 사료작물 작부체계 구성시 조숙옥수수의 생산성을 확보하기 위해 만파시밀식재배를 시도하였다. 조숙옥수수로는 Comet80, Comet85, Linda 품종을 이용하였고 만파정도는 수원19호 적기보다 45, 55, 65일 만큼 늦게 파종하였다. 파종밀도는 각 파종기에 대하여 60
Early maturing hybrids(Comet 80, Comet 85 and Linda) and mid-late maturing hybrid (Suwon 19) were grown at Suwon to study the influence of maturity, plant population, and sowing date (45, 55, and 65 days delayed from the recommended sowing date of Suwon 19) on the dry matter yields, percentage ears and TDN yields. Com was planted at the density of 60 x 20, 50 x 20 and 40 x 20 em. Dry matter yields were not significantly different between the early and mid-late maturing hybrids in the delayed sowing time, but significantly higher in 20 x 50cm of planting density in early maturing hybrids. As sowing was delayed to Jun. 22 ear content decreased from 40.3% (early maturing hybrid) to 6.7% (Suwon 19). This resulted in significantly 24.1% higher TDN yield in Comet 85 than in Suwon 19.
