Effects of Different Organic Fertilizers and Fertilization Method on Red Pepper Growth and soil Chemical Properties

Abstract

In this study, we investigated the effect of different organic fertilizers and fertilization system on red pepper (Capsicum Annuum L.) growth and soil chemical properties. This experiment was carried out; 1) to compared growth and soil chemical properties by different organic fertilizers (MEC: mixed expeller cake, MOF: mixed organic fertilizer, OCF: organic complex fertilizer), and 2) to evaluate the effect of fertilization methods (NPK treatment, Organic fertilizer treatment). Organic fertilizers were applied with two different methods: single application (SA) and split application (SP). The highest yield and nitrogen use efficiency were observed in MOF with SP method. After harvest, soil pH was decreased but, Electrical conductivity was increased in all organic fertilization treatments due to increasing of nitrogen compound such as NO 3 -N and NH4-N. This result indicated that MOF with SP was effective agricultural practice compared to NPK treatment. However, further study should be required to evaluate long-term effect of organic fertilizer application on soil properties and crop yield.

Primary Metabolomic Changes in Rice Plants Grown under Different Levels of Food Waste-Livestock Manure Compost

“…The remarkable increase in tiller by higher nitrogen input significantly produced the reproductive tillers, which affect the number of panicles. The greater input, a critical point to avoid crop damage, of FW-LMC-based fertilization significantly promoted biomass production in rice (Cho et al, 2021), red pepper (Kim et al, 2020) and Chinese cabbage (Kim et al, 2018(Kim et al, , 2021 although greater and longer input could lead to the enhancement of soil EC to cause unfavorable crop production (Yoo et al, 2018;Kim et al, 2019Kim et al, , 2021Lee et al, 2019). Therefore, the current result provides a possibility that higher input of nitrogen source, especially an organic resource such as FW-LMC, in rice cultivation system could markedly enhance the vegetative growth as well as the reproductive production.…”

Soil Labile Organic Carbon Fractions and Carbon Management Index in Response to Different Fertilization under Organic Maize Farming System

“…That is due to the organic acids released from mineralization process of organic materials (Kim et al, 2020). Soil labile organic C fractions The effects of different fertilization treatments on soil labile organic C fractions (WEC, HWEC, MBC, POXC, POC and LPOC) are shown in Fig.…”

Effect of Organic Fertilizer Application on Plant Growth and Soil Chemical Properties under Different Crops Cultivation

“…유기질비료는 토양에 투입 후 무기물질로 분해되어 작물에 양분을 공급함으로 무기질비료에 비해 상대적으로 완 효적인 특징을 가지고 있으며 (Cho et al, 2009;Kim et al, 2018bKim et al, , 2020b, Kim et al (2018b)에 따르면 국내 유통상 품분석 결과 평균 양분 함량이 질소 4.8 -4.9%, 인산 2.5 -3.1% 및 칼리 1.7 -1.8%로 보고 하였다. 이러한 유기질비료 는 양분공급능 뿐만 아니라 토양 유기물을 공급함으로 토양의 건정성을 향상시킬 수 있다고도 알려져 있다 (Yoon et al, 2012;Kim et al, 2019).…”

“…그러나 유기질비료의 사용은 장점뿐만 아니라 단점도 존재하는데 가장 큰 문제점은 과다 사용에 따른 농업환경 오염이다. 최근까지 벼, 옥수수, 상추, 마늘, 고추 등 다양한 작물에 대한 유기질비료 사용에 대 한 효과가 평가되고 있으며 적정사용량에 대한 연구도 수행되고 있다 (Lim et al, 1983(Lim et al, , 1990Kim et al, 1998Kim et al, , 2018aKim et al, , 2019Kim et al, , 2020b…”
