Abstract

The present study was conducted to evaluate fertigation effects of balanced manure nutrients from combined fertilizers on the growth of eggplant (Solanum melongena L.) and soil chemical properties in greenhouse cultivation. There are 4 treatments for fertigation; animal liquid manure (LM), LM supplemented with chemical ferilizer (LM+CF) to make nutrient-balanced ferilizer, LM supplemented with chemical ferilizer and phosphorus acid (LM+CF+PA), and conventional chemical fertilzer (CCF). Fruit lenth, width, and weight for LM treatment were significantly lower than LM+CF, LM+CF+PA, and CCF treatments. There was no significant differences in fruit length, width, and weight among LM+CF, LM+CF+PA, and CCF treatments. The yield of eggplants per plant for LM treatment (26.2 kg) was decreased by 6% compared to CCF treatment (27.9 kg). The growth and yield of eggplants were not significant different among CCF, LM+CF, and LM+CF+PA treatments. The marketable yield for LM treatment was lowest among 4 treatments and that for LM+CF+PA treatment (26.6 kg) was increased by 8% compared to CCF treatment (24.1 kg). The chemical properties of the soil for CCF treatment, in general, tended to be higher compared to the other treatments. In conclusion, the present study demonstrates that the application of balanced liquid manure combined with mineral fertilizer to soil is considered as a good management practices because it improves, eggplant quality and soil properties.

본 연구는 가축분뇨 액비와 양분을 조정한 맞춤액비의 관비처리가 시설 하우스 재배에서 가지 생육, 토양 화학성에 미치는 영향을 알아보기 위하여 수행되었다. 시험구처리는 가축분뇨액비(LM), 가축분뇨액비에 화학비료를 첨가한 양분조정 맞춤액비(LM+CF), 가축분뇨액비에 양분과 아인산 첨가 맞춤액비(LM+CF+PA) 처리구와 화학비료 관행처리구(CCF)를 두었다. 가지의 과장, 과폭, 과중은 LM 처리구가 LM+CF, LM+CF+PA 및 CCF 처리구에 비해 유의적으로 낮았다. LM+CF, LM+CF+PA 및 CCF 처리구 간에 과장, 과폭 및 과중의 유의적 차이는 나타나지 않았다. 가지 주당 수량은 CCF 처리구(27.9 kg)에 비하여 LM 처리구(26.2 kg)에서 6% 낮았다. 가지의 생체중은 CCF와 LM+CF 및 LM+CF+PA 간에 통계적으로 유의한 차이를 나타내지 않았다. 가지 주당 상품수량은 LM 처리구에서 가장 낮았으며, CCF 처리구(24.1 kg)에 비하여 LM+CF+PA 처리구(26.6 kg)에서 8% 증가하였다. 토양의 화학성은 CCF 처리구가 다른 처리구에 비하여 전반적으로 높은 경향이었다. 이상의 결과를 종합해 볼 때 화학비료의 관행시비에 비하여 가축분뇨 액비에 화학비료를 첨가한 맞춤액비에 의한 관비가 가지의 상품생산성 향상 및 토양의 화학성 개선에 유리한 시비방법으로 생각된다.
