The Effect of Different Rates of Tobacco Leaf Extract in Insect Pests Control in Cowpea Production

Abstract

Field experiment was conducted under rain fed condition at the College of Education school farm Akamkpa, Cross River State during the 2021 cropping season to investigate the effect of different tobacco (Nicotianatobaccum L.) leaf extract in the control of field pests in cowpea. A randomized Complete Block Design (RCBD) was used with five treatments and three replicates. Treatments (T) consist of T1 (No application), T2 (0.05kg of tobacco extract + 100g caustic in 5 liter of water, T3 (1kg tobacco extract + 100g caustic soda in 5 liter of water, T4 (1.5kg of tobacco extract + 100g of caustic soda in 5 liter of water), T5 (karate insecticide at 2.5ml/l) Growth parameters (Plant height and number of branches per plant) and yield parameters (Number of pods/plant, number of seeds/pod, 100 seeds weight and net yield) were determined. Result showed that there was significant (P<0.05) plant height and number of branches at 40 days after planting. There was significant (P<0.05) difference in number pods/plant, 100 seeds weight and net yield among the treatments. Treatment five (T5) gave the highest rate of return per naira among the treatments followed by treatment three (T3). Therefore, based on this study if tobacco extract were to be used, treatment three [(T3) 1.00 kg (tobacco extract) is recommended.
