“…The majority of the respondents (91.5%) were between 20 and 50years of age whilst only 8.5% were above 50 years. This result is consistent with the finding by Asare-Bediako et al (2015) which states that most pepper farmers in Ghana are in the age range of 30-59 years. This suggests that most of the respondent farmers were within the productive age (Apantaku et al, 2016).…”

“…Table 2 also indicates that the majority of the farmers were in the age range of 31 and 60. This result is in line with the report by Asare-Bediako et al (2015) which stated that most pepper farmers in Ghana are in the age range of 30-59 years. This implies that most of the respondent farmers were within the productive age (Ibitoye, 2013;Apantaku et al, 2016).…”

“…During chitosan treatment, physiological characteristics of plant growth, including plant height and leaf number, plus chlorophyll content were measured. Plant resistance towards Phytophthora capsici was observed on day ten postinfection by assessing the disease incidence index (DII) and disease severity index (DSI) as described by Asare-Bediako et al (2015). DII is an indexing method that gives a score of 1 (infected plant) to 0 (uninfected) based on visual observation, whereas DSI utilises a broader range of scores from 0 -5 based on the severity of the infection.…”

Phytophthora capsici is one of the primary pathogens causing a global problem of severe losses in chilli production. The use of conventional fertilisers and fungicides to improve chilli production had been shown to elevate environmental and health issues. Hence, the foliar application of chitosan, natural deacylated chitin, to enhance growth and resistance in chilli pepper plants was investigated. The chilli plants were grown for 14 days before receiving chitosan application and 33 days before Phytophthora infection, physiological parameters were recorded during the growth period, and expression of resistance related genes was quantified at 72 hours after infection. Our results showed that physiological parameters, such as increment of height and leaves number, and chlorophyll content indicated an improved growth process in chitosan treated plants compared to the control. Plant resistance to Phytophthora infection was also investigated following chitosan application to highly (CM334), moderately (LABA), weakly (LADO) resistant and susceptible (15080) cultivars. The disease incidence and severity indices were reduced in chitosantreated plants, except in highly and moderately resistant cultivars. Further, expression was also quantified for defence-related genes, including 9-lipoxygenase (CaLOX), Ca2+-bound calmodulin 1 (CaCaM1), receptor-like cytoplasmic protein kinase (CaPIK), Pto-interacting1 (CaPTI1) and resistance gene analogue 2 (CaRGA2). The results suggest that CaLOX, CaPTI1 and CaRGA2 genes were involved in defence mechanism to Phytophthora, with increased expression during infection. However, expression levels were reduced when Phytophthora infection was coupled with foliar chitosan application, indicating that chitosan may play a direct role in decreasing the pathogenicity of Phytophthora. In conclusion, this study suggests the promising role of chitosan as an alternative to conventional fertiliser and fungicide in chilli pepper plant.
