Termite Population Dynamics in Arenic Kandiudults as Influenced by Tillage and Organic Manure sources in a cassava (Manihot esculenta Crantz.) farm
Termites have been identified as one of the major pests of cassava in Nigeria especially on infested soils. Termite Population Dynamics in Arenic Kandiudults as Influenced by Tillage and Organic Manure Sources in a Cassava Farm in Owerri, Southeastern Nigeria, was investigated in this study. Three years of field trials were carried out in 2007, 2008 and 2009 cropping seasons respectively at the Teaching and Research Farm of the Federal University of Technology Owerri. The experiment was laid out in a 3x6 split-plot factorial arrangement fitted into a randomized complete block design (RCBD) with three replications. The TMS 4 (2)1425 was the cassava cultivar used. Treatments consisted three tillage methods (zero, flat and mound), two rates of municipal waste (1.5 and 3.0 tons/ha), two rates of Azadirachta indica (neem) leaves (20 and 30 tons/ha), control (0 tons/ha) and a unit dose of carbofuran (chemical check). Result shows that carbofuran significantly (P=<0.0001) recorded least termite population per square meter after tuber harvest, whereas A. indica leaves and municipal waste increased termite population per square meter. Also, cassava tuber yield was significantly influenced with application of A. indica leaves and municipal waste than carbofuran and control, while termite population per square meter and tuber yield were not affected by tillage method.
