Abstract

This study was conducted to evaluate effect of plants number per hill (PNH) on growth and yield of sorghum in drained paddy field for 2 years. Crop growth and development and yield in the field was examined to know the efficiency of proposed cropping system. At seeding after 40 days, leaf number and stem diameter were highest at 1 PNH plot, on the other hands, plant height was at 5 PNH plot the $1^{st}$ and $2^{nd}$, respectively. The harvest stage, 5 PNH plot was highest culm length of 183, 188 cm the $1^{st}$ and $2^{nd}$, however, culm diameter was lowest. Culm length of sorghum was highest by 183, 188 cm at 5 PNH plot also, culm diameter was thickest by 19.18, 20.13 mm at 1 PNH, respectively. Yield components of ear length, seed number per ear and 1000-seed weight were highest at 1 PNH the $1^{st}$ and $2^{nd}$, respectively. As yield of sorghum was highest at 2 PNH plot $344kg{\cdot}10a^{-1}$, $382kg{\cdot}10a^{-1}$ yearly, respectively that it were in order of 1 PNH plot > 3 PNH plot > 4 PNH plot > 5 PNH plot.

본 연구는 건강 기능성 농산물로 각광을 받고 있으면서 수요와 재배면적이 점차 확대되고 있는 수수의 생산량 증대와 자급률 향상을 위한 체계적인 재배기술을 확립하기 위한 기초자료를 얻고자 고휴점파 본수에 따른 생육 및 수량에 관한 연구를 수행하였다. 1. 파종본수에 따른 초장에서 파종본수가 증가할수록 길어지는 경향이 뚜렷이 나타났으며 엽수에서는 파종본수가 가장 적은 1본 처리구에서 8.0개로 많았으며 엽수가 가장 적게 나타난 5본 처리구와 연차간 각각 1.4, 1.5개의 차이가 나타났다. 경태에서도 파종본수가 증가할수록 얇아지는 경향이 나타났으며 1본 처리구 대비 72.6, 74.3%의 차이가 나타났다. 2. 수확기의 간장은 1, 2년차 모두 파종본수가 증가할수록 길어지는 뚜렷한 경향이 나타났으며 가장 길게 나타난 5본 처리구 183, 188 cm와 가장 짧게 나타난 1본 처리구간 각각 41, 29 cm 차이가 나타났다. 간경에서는 1본 처리구에서 가장 굵은 19.18, 20.13 mm로 나타났으며 파종본수가 증가할수록 얇아지는 경향으로 나타났다. 3. 수량구성요소를 보면 이삭장 및 이삭당 종실수, 천립중 모두 연차간 파종본수가 적을수록 길고 많거나 무거운 것으로 나타났으며 수량에서는 연차간 파종본수가 2본 처리구에서 수량구성요소에서 높은 값을 보인 1본 처리구 보다 111%, 116% 높은 것으로 나타났다.
