“…In most cases the improved varieties had better partitioning of dry matter into the roots compared with the local varieties. Most local farmerpreferred varieties are tall and non-branching due to several years of careful selection of intercropping-compatible cassava varieties [35][36][37][38]. The improved varieties used were mostly early branching and as such had the tendency to convert most of their assimilates into storage root bulking earlier in the growing season thereby resulting in much higher root yield.…”

This study was carried out to identify and select local and improved cassava varieties suitable for cultivation in the transition and Guinea savannah agroecology of Ghana against climate change. Two agroecologies; transition and Guinea savannah ecologies were considered for the study. Four cassava growing communities were chosen in the transition zone whilst three cassava growing communities were chosen for the Guinea savannah ecology. The cassava varieties representing the treatments were arranged in a randomized complete block design with three replications at each location. A total of 13 cassava varieties were used for the study. Cassava cuttings measuring 20-25 cm were planted using a spacing of 1m × 1m. Harvesting was done at 12 months after planting to assess storage root yield of the cassava varieties at the different locations. Analysis of variance indicated significant (P≤ 0.05) varietal differences among the local varieties for root yield (11.25 - 29.27 t/ha), harvest index (0.46 – 0.75), storage root number per plant (2 - 8 roots/plant) and mean storage root weight (307.0 - 972.4 g) in Transition zone. However, there were no significant varietal differences between the improved varieties for root yield. The best performing improved varieties in the transition zone were Bankyehemaa (28.06 t/ha), Eskamaye (27.76 t/ha) and Nkabom (26.99 t/ha) whilst Filindiakong (22.65 t/ha) and Nyerikobga (31.17 t/ha) were identified to be suitable for the Guinea savannah ecology. Therefore, these cassava varieties can be cultivated to mitigate the effects of climate change on cassava and ensure food security.

“…Mono-pepper as a control (P-mono). Phyllosticta leaf blight disease incidence and severity were then monitored on the pepper plants in each treatment plot by using a modified formula-grading scheme [4]. The data on disease incidence and yields of pepper were analyzed using the SAS computer package, version 9.4.…”

“…Intercropping is an important and effective way in reducing the incidence of disease on pepper [3]. Intercropping reduce the infection of Pepper Veinal Mottle virus (PVMV) incidence when pepper was intercropped with maize, cassava and plantain by 90%, 95% and 92.7%, respectively [4]. Intercropping pattern of pepper, corn and taro reduced the viral diseases incidence rate on pepper [5].…”

Abstract. Field experiments were conducted to investigate the most effective intercropping pattern of capsicum and maize/soybean to reduce the incidence of pepper phyllosticta leaf blight disease. The treatment combinations were P-mono, P2M1, P4M2, P6M2, P2S1, P4S2, P6M2, P4S1M1 And P6S1M1, (P, Pepper; M, Maize; S, Soybean; 1-6, number of rows of capsicum, maize or soybean per plot). The results showed that combination of C2M1, C4M2 and C6M2 reduced incidence of phyllosticta leaf blight, with the incidence rate from 25.0% to 29.1%, which were significantly over their counterpart mono capsicum treatment (incidence rate, 41.6%). The combination of C2M had the most drastic effect in reducing the disease on pepper. The incidence of the disease increased with increasing number of rows of capsicum in the intercrop combination. The combination of capsicum-soybean had no effect on the incidence of the disease. The disease index ranged from 3.9 % ~ 4.5% in pepper-maize, significantly lower than the other 6 treatments. The efficacy was ranged from 2.4% to 53% at the end of assessment, and the intercropping system of P2M1 achieved the highest efficacy (53%). The results signified that particular agro-ecological systems are effective approach in diseases control on pepper, and the proper intercropping pattern might decrease the input quantity of pesticides in capsicum planting systems.

“…Because of the nonpersistent mode of transmission of PVMV and CMV, insecticide spraying is often inefficient to control them in the field (Afouda et al, 2013). Therefore, control methods include mostly prophylaxis and plant genetic resistance (Caranta et al, 1996;Fajinmi & Fajinmi, 2010).…”

The prevalence of viruses in pepper crops grown in open fields in the different agro‐ecological zones (AEZs) of Côte d'Ivoire was surveyed. Pepper veinal mottle virus (PVMV; genus Potyvirus) and Cucumber mosaic virus (CMV; genus Cucumovirus) were the most frequent viruses among those surveyed, while tobamoviruses (genus Tobamovirus) were detected at low frequency. PVMV showed a high heterogeneity across AEZs, which may be related to climatic, ecological or agronomical conditions, whereas CMV was more homogeneously distributed. The molecular diversity of CMV and PVMV were analysed from partial genome sequences. Despite the low number of CMV isolates characterized, two molecular groups were revealed, one corresponding to subgroup IA and the other to reassortants between subgroups IA and IB. RNAs 1 and 3 of the reassortants clustered with the IB subgroup of CMV isolates, whereas their RNA 2 clustered with the IA subgroup. Importantly, RNA 1 of CMV isolates of the IB subgroup has been shown to be responsible for adaptation to pepper resistance. The diversity of PVMV in the VPg‐ and coat protein‐coding regions revealed multiple clades. The central part of the VPg showed a high level of amino acid diversity and evidence of positive selection, which may be a signature of adaptation to plant recessive resistance. As a consequence, for efficient deployment of resistant pepper cultivars, it would be desirable to examine the occurrence of virulent isolates in the CMV or PVMV populations in Côte d'Ivoire and to follow their evolution as the resistance becomes more widely deployed.
