Data were generated through a survey of 320 farmers randomly selected from the four agricultural zones of Oyo State Agricultural Development Programme (OYSADEP). The socio-economic characteristics of respondents were described using frequency counts and percentages. Inferential statistics such as chi-square was used to test the hypotheses. Geographic Information System (GIS) software (ArcView 9.3) was used to map locations and analyse distances and multiple buffers were developed around input centers to determine farmers' accessibility. Results from the study show that inputs like fertilizer (65%), agro-chemicals (94.38%), and planting materials like seeds and stems (90.63%) were majorly procured from private input centers. Majority (74.37%) of the farmers interviewed travel more than 15 km to procure input from government established input centers. Chi-square results showed significant relationship between sex (χ2=29.51, P=0.05), marital status (χ2=10.97, P=0.00), income (χ2=32.55, P=0.00) and farm size (χ2=14.73, P=0.00). Improvement in agricultural output will depend to some extent on farmers’ access to agro-input centers. The government should establish agro-input input centers closer to farmers and make inputs available at subsidized rates; this will make them affordable to farmers and increase agricultural production.","PeriodicalId":174273,"journal":{"name":"Ghana journal of agricultural science","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-07-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132161806","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study used data collected from a multistage sampling of 80 yam farmers. Analytical techniques used include descriptive statistics and probit model. The results showed that majority of farmers in the study area are ageing, with a mean age of 57.21. It was also observed that there were more males (87.5%) than females (12.5%) and that 71.2% of farmers had formal education. The result of probit analysis showed that farm size (0.81, p = 0.002) was a significant factor determining the willingness of farmers to export. This means as the farmers' farm size increases so also is their willingness to export. The result also revealed that an increase in other occupation (0.96, p = 0.154) of the respondents will bring about an increase in their willingness to export yam. This suggests that farmers who had other sources of income might be more willing to export yam. It was therefore concluded that when more land is allocated to yam production and financial support is made available to farmers in the study area, their willingness to export yam would increase.","PeriodicalId":174273,"journal":{"name":"Ghana journal of agricultural science","volume":"46 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-07-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132992713","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The results indicated that replacing fishmeal with BSFLM significantly improved weight gain, feed conversion efficiency and production efficiency factor (PEF). No detrimental effect was observed on carcass and specific organ measurements. Using the partial budgeting approach on a 500-bird estimation an increase of one thousand, one hundred and eleven Ghana cedis (GH₵1,111.00) was obtained when the fishmeal was replaced with BSFLM. Also, an increase of four hundred and sixty-seven Ghana cedis (GH₵467.00) was estimated when soybean meal was partially replaced with BSFLM.

This study evaluated the impact of different N fertilizer levels on maize varieties in oil palm-maize intercropping system. The economics of nitrogen application was also studied. The treatments were: T1-Sole oil palm, T2-Oil palm+‘Omankwa’, T3-Oil palm+‘Abelehi’ and T4-Oil palm+ ‘Obatanpa’. The crop associations were superimposed with nitrogen fertilizer levels as sub-treatments at N0- N0:P0:K0, N1-N60:P60:K60, and N2-N120:P60:K60 per ha. The experiment was a split plot design with 4 replications. There was no significant difference (p< 0.05) between maize varieties across seasons for both maize yield and aboveground biomass though ‘Omankwa’ was promising across seasons and more responsive to nitrogen application. Across the three maize varieties, N60P60K60 was significantly higher (p<0.05) by 40% and 17% for maize yield and aboveground biomass respectively as compared to N0:P0:K0. The study recommends N60P60P60 fertilizer level and further states that to improve fertilizer adoption, government should subsidize fertilizer cost for farmers to purchase. The outcome of cost benefit analysis revealed that return per cash invested favored cropping system with N60:P60:K60 and season with less water stress.","PeriodicalId":174273,"journal":{"name":"Ghana journal of agricultural science","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-07-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121311615","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Protein contents of mpotompoto-fortified fish products ranged from 3.75% to 8.5%. Ash also ranged from 1.12% to 5.54%. The control contained 1.17%. Acceptability tests were conducted on the fortified snacks using a 5-point hedonic scale. On the whole, fortified products showed significantly higher levels of protein and ash over the non-fortified snacks. Acceptance of the snacks by pupils (11-12) years was high enough to warrant incorporation of the fish powders into a school lunch menu.","PeriodicalId":174273,"journal":{"name":"Ghana journal of agricultural science","volume":"240 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-12-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115242540","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Results indicated generally strongly acidic soil and exchangeable acidity values obtained were high and consistent with very acidic soil conditions. There were generally- high C: N ratios (>20) except some few sites, thus supplementary nitrogen is required to reduce C: N ratio and improve N availability. The Total Exchangeable Bases (TEB), Effective Cation Exchange Capacity (ECEC) and available P values were less than the optimum values for sustainable oil palm production. Both soil and foliar analysis indicated that soils in areas assessed have low soil fertility with relatively good soil physical conditions.

The experiment was laid out in a completely randomized design with three replications. The number of second stage juveniles (J2) per 250 cm 3 of soil sample were counted while the severity of root-knot nematode damage (root galls) was assessed. The reproduction index (RI) was used to classify the varieties as resistant or susceptible. There was a significant difference (P < 0.05) in the number of second stage juveniles of root-knot nematode (RKN), galling index and RI among the genotypes tested. The study revealed that cowpea genotypes SARI 1-4-90, Padi tuya, Songotra, IT99K-1122, Sanzi and Apagbaala were moderately resistant whereas cowpea genotypes IT86D-610, Zaayura, SARI 5-5-5 and IT07K-299-6 were slightly resistant.
