Effect of Swine Manure Extract by Foliar Application and Soil Drenching on Dry Matter and Nutrient Uptake of Cassava
Year: 2011
Type: article
Abstract: Swine manure extract (SME) is the aqueous liquid obtained by steeping dried swine manure in water for 24 hr and contains plant nutrients. The objective of this study was to compare the effects of nine split applications of SME as foliar fertilizer (FSME) or soil fertilizer (SSME), as well as both soil and foliar fertilizer (FNSSME) and conventional NPK fertilizer (NPK) on the macronutrient and micronutrient uptake of the cassava cultivar Hauybong60. At harvest, 10 mth after planting, the combination of foliar and soil applications of SME favored dry matter and tuber yield improvement and tended to increase the macronutrient and micronutrient uptake by cassava plants. Cassava treated with FSME and NPK produced no signifi cant difference in total dry matter yield, fresh tuber yield or nutrient accumulation in the shoots. The combination of soil and foliar SME application was effective in promoting dry matter, tuber yield and the macronutrient and micronutrient uptake in cassava plants grown on slightly alkaline, loamy soil.
