BIOEFFICACY OF CHILLI PEPPER Capsicum frutescens (L.) AND IT’S INTERCROPPING ON THE GROWTH, YIELD...

The experiment was set up as a 3x4 factorial experiment with three treatments (chilli pepper extract at 200 l/ha, 250 l/ha, and local control) at three replications arranged as alternate intercropping, strip cropping, border cropping, and sole cropping of cowpea with 12 plots and 60 ridges in a randomised complete block design with 12 plots and 60 ridges. With the purpose of protecting the cowpea plants, 200 l/ha and 250 l/ha of chilli pepper aqueous extract were sprayed on them at a spraying schedule of 10 a.m. to 12 p.m. Post-planting growth parameters, pest population and bug incidence on cowpea, pod density, pod damage, grain yield, yield loss, and phytotoxicity signs, as well as pod density, pod damage, grain yield, yield loss, and phytotoxicity signals, were all collected. The data collected was analysed using Analysis of Variance. In an intercropping setting, plots treated with 250 l/ha aqueous extract had fewer thrips (3.790.11), legume pod borer (1.760.24), legume pod borer nymph (1.170.06) and adult (1.070.05), and pod sucking bug adults (1.190.07) than plots treated with 200 l/ha aqueous extract (1.310.09). When compared to the untreated control, there was a significant difference (p 0.05) in pod damage and increased grain yields (0.120.00) between the treated plots (1.190.02) and the untreated plots (1.460.02). (0.070.00). The damage created by 250 l/ha is greater than the damage produced by 200 l/ha in total. Glycosides, tannin, terpenoides, flavonoids, saponin, reducing sugar, steroids, and resins may be involved in the biopesticidal effect of chilli peppers on cowpea insects. Other aqueous extracts and cropping strategies are inferior to 250 l/ha and alternate intercropping, according to the study. Alcoholic extracts of C. frutescens insecticides, on the other hand, may be more effective than water extracts as an insecticide. The age of the sample after preparation, as well as the storage circumstances, will need to be thoroughly evaluated, since these factors could influence the evaluation of any plant material as a biopesticide.
