A Fast and Reliable Screening Method of Organic Materials for Crop Cultivation

Abstract

Strategic utilization of organic material for agriculture is important for improve efficiency in organic agriculture. Waste from food processing is a good candidate for compost material, and the first critical step is to choose proper raw material. In this study, we tried to establish a reliable screening method by comparing growth of different plant parts in different crops in combination with serial dilution of raw material extracts. The raw materials compared here are tangerine pomace, herbal medicinal plant waste, bread, spent coffee ground (SCG). We also compared effect of organic fertilizer made of SCG, natural pesticides made of pyrethrum extract and neem oil. The results obtained from different kind of crops and plant parts give insight into growth enhancing or inhibitory effect of tested material which will be useful screening raw material to make organic fertilizer and crop protective materials.
