The study was carried out in 13 villages under three Upazila’s namely Hathazari, Fatikchari and Satkania of Chattogram District, Bangladesh during 2017-18 covering 210 farmers in the selected locations. Results revealed that the rate of adoption of cowpea (BARI Cowpea-1) was found to be higher (71%) than that of the local and mixed varieties. The highest number of the respondents came to know about BARI Cowpea-1 from DAE (58.6%) followed by seed dealers (31.7%), research stations (19.0%) and NGO’s (17.0%). The average yield of BARI Cowpea-1 was recorded at 0.613/ha irrespective to all locations; which indicated that the productivity of this variety has been declined due to perhaps mixed cultivation practices with the local variety, lack of knowledge on modern production technologies, lack of irrigation water during the dry seasons and not using the recommended dose of manures and fertilizers. Thus the adoption rate of individual production technology of BARI Cowpea-1 was found unsatisfactory. But it still might project promises; if the farmers could be acquainted, trained and put in practice with the modern production technologies. The respondents had agreed upon significant positive socio-economic impacts of cowpea cultivation on their livelihoods; so it’s needed to motivate farmers to follow the recommended production technologies for gaining higher yield from this variety or alternatively needs to develop and release new varieties for this region.
Contribution/ Originality
This study is one of very few studies which have investigated the adoption status of a BARI released cowpea variety, BARI Cowpea-1 and its specific production technologies at field level and the factors influencing adoption/ non-adoption for developing new cowpea varieties for the region.

Field experiments were carried out to evaluate the adaptability of Bambara groundnut (Vigna subterranea (L) Verdc) varieties to rainforest agro-ecological zone of Delta State using selected varieties. The varieties used were: EXMF1, EXMF2, EXMF3, EXMF4, IITA355, IITA182, IITA165, IITA1480, IITA1132, ENZK1 and ENZK2. The aim of this experiment was to identify the varieties of Bambara groundnut that were most suitable in this agro-ecological zone. The design used in this experiment was a Randomized Complete Block Design (RCBD) replicated three times. The parameters collected were: plant height, petiole length, number of leaves, total leaf area, number of pods per plant, pod and seed weights per plant(g), and seed yield (kg/ha). The result showed that varieties EXMF1, EXMF4, IITA165 and ENZK2 performed better than others for growth (plant height, number of leaves and total leaf area) and seed yield. Variety EXMF4 was outstanding in yield with the mean value of 5267kg/ha followed by ENZK2 with the mean value of 5000kg/ha. The least in yield was IITA182 followed by ENZK1 with the values of 2445 and 2600kg/ha respectively.
Contribution/ Originality
The paper's primary contribution is finding that some varieties of Bamabra groundnut not only thrived but compete with the yield found elsewhere.

DOI: 10.18488/journal.70.2020.71.30.38
Smallholder farmers in Cameroon often store seeds from their own-harvest for use in subsequent planting seasons, but they have limited information on appropriate materials for long-term storage of vegetable seeds. Hence, six different materials (sealed aluminium foil sachet, sealed glass bottle, closed plastic cup, sealed paper sachet, sealed polythene sachet, and open-and-seal glass bottle) were evaluated for their effectiveness as storage materials for huckleberry seeds. Factorial ANOVA revealed significant (P < 0.001) effect of the different types of storage materials, duration of seed storage, and their interactions on laboratory germination, field emergence, and percentage transplantable see dlings. Significant (P < 0.05) variations were observed for laboratory seed germination and field emergence from months 2–5 of preservation across the different storage materials, with the highest performance exhibited by sealed aluminium foil sachet, while glass material exhibited the lowest performance. These performances decreased significantly (P < 0.05) for each storage material across months of long-term storage, with the lowest decrease recorded in sealed aluminium foil sachet and highest decrease recorded in glass bottle storage materials. Percentage transplantable seedlings decreased significantly (P < 0.05) from month 0–5 for each storage material, with lowest decrease in sealed aluminium foil sachet and highest decrease in open-and-seal glass bottle. Overall, these results demonstrate that sealed aluminium foil sachet is the most effective storage material for long-term preservation of huckleberry seeds under ambient conditions of the study area, which can be adopted by farmers.
Contribution/ Originality
This study is one of very few studies that have investigated different storage materials for long-term preservation of huckleberry seeds in Cameroon, and demonstrated that sealed aluminium foil sachet is the most effective under ambient conditions in the study area, which can be adopted by smallholder farmers.

Potato is suffered by many abiotic and biotic factors. Among biotic factors late blight disease (LBD) is the most important. The study was conducted during 2017 at Adet and Debre-Tabor to determine and evaluate the combination effect of varieties and fungicides, to reduce LBD intensities and increase yield. Four potato varieties and three fungicides with untreated check were used in factorial randomized complete block design with three replications. Lowest disease severity 11.11% was obtained from Belete and Gudene at Adet and Belete at Debre-Tabor. Similarly, the lowest AUDPC (9.33 and 89.83 %-days) were expressed from Gudene + Saboxyl 72% at Adet and Debre-Tabor, respectively, whereas, the maximum PSI and AUDPC were obtained from untreated plots. In average up to 359.81% yield increases were recorded from Abalo + Saboxyl 72% WP. The highest marginal rates of return (2,886.50 % and 3,786.35%) were obtained from Saboxyl 72% treated plots of Abalo & Guassa at Debre-Tabor and Adet, respectively. Therefore, an application of Saboxyl 72% with different varieties was effective at both locations to reduce the yield loss of potato and could be recommended to manage LBD. The combination of Saboxyl 72% with Gudene, Belete and Guassa were highly hinder LBD development at both locations. Even though, its yielding capacity was relatively lower Gudene could be recommended for production without fungicide. Variety Belete and Guassa could be recommended for production in combination with Saboxyl 72%, since they have best performance with relatively lower disease reaction at Adet and Debre-Tabor, respectively.
Contribution/ Originality
This study contributes in the existing literature to fill the gap of the current state of knowledge of late blight disease management of potato. This study is one of very few studies which have investigated potato late blight disease management in Western Amhara Region Ethiopia.

The Effect of Varieties and Fungicide Spray Frequencies on Septoria Leaf Blotch (Mycosphaerella graminicola) Epidemics on Bread Wheat in Western Amhara, Ethiopia.

Bread wheat (Triticum aestivum L.) is one of the most important small grain cereals produced worldwide. Despite its economic significance, wheat production and productivity is challenged by biotic and abiotic factors. Septoria leaf blotch (Mycosphaerella graminicola), is among the most important pathogens that inflict qualitative and quantitative losses on susceptible wheat varieties in the Ethiopian highlands. A field experiment was conducted at Adet and Debre Tabor, three frequencies of fungicide (propiconazole, Tilt 250 EC) plus check and three varieties (Alidoro, Danda’a and Gambo) were used. The experiment was laid out in a randomized complete block design (RCBD) in factorial arrangement with three replications. SLB disease development was quite high at Debre Tabor compared to Adet. At Debre Tabor, the maximum SLB severity (78.8%) was noted on variety Gambo followed by Danda’a (70.3%) whereas 46.09% and 37.44% severities noted on these varieties at Adet, respectively. At Debre Tabor the highest sAUDPC (44.35%days and 39.8 %days), disease progress rate (0.019402 and 0.035895 unit/day) on all and flag leaves, respectively. The highest Septoria progress coefficient was noted from the unsprayed plot of Gambo (0.76). Based on the results, a single fungicide spray (Tilt 250EC) for Alidoro and Danda’a (moderately resistant and moderately susceptible) could minimize the epidemics of SLB. But for Gambo (susceptible variety) two fungicide spray reduces the progress and development of SLB. Timely application of efficient systemic fungicides could reduce the epidemics of the pathogen. However, other cultural methods could be further study for the epidemics of this particular pathogen.
Contribution/ Originality
This study is one of very few studies which have investigated the combined effect of varieties with fungicide spray frequencies on Septoria leaf blotch epidemics that will have a positive contribution for economic fungicide spray and as integrated Septoria leaf blotch disease management.
