Climate-Smart Agriculture (CSA) is proposed to solve climate change impacts on agriculture. Smallholder farmers are adopting various strategies to be resilient to climate change effects. Empirical research is required to evaluate CSA utilisation in Ghana. Lawra, Jirapa and Nandom districts in the climate-risk areas of Guinea Savannah agro-ecological zone were chosen and Participatory Rapid Appraisal (PRA) tools were used. Farm budget analysis and market price methods were employed; key financial decision-making tools were net returns, profit margins and benefit-cost ratio. Soft systems content analysis, frequencies, means, ranking and data aggregation were employed to generate results. CSA use in the study districts was smallholder driven and male dominated. CSA was mainly used for staples including cereals and legumes and small ruminants under livestock. Crop-livestock integration and crop rotation were the common CSA practices with the highest costs (GH¢6,370.00) and highest revenues (GH¢9,460.00) respectively. Utilisation of CSA in the districts is beneficial and investments are profitable and financially viable. All actors and stakeholders must join forces to promote CSA in the districts. Rigorous promotional campaigns, capacity building and funding at all levels are crucial for CSA adoption in Ghana.","PeriodicalId":174273,"journal":{"name":"Ghana journal of agricultural science","volume":"418 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-12-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115577879","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}

Soil samples were collected at 90-days after planting from the rhizosphere of sweet potato crop and analysed using Modified Baermann tray method from 100 farms across the study area. Seven plant-parasitic nematode genera were extracted from soil samples collected and morphologically identified under a microscope with four of them, namely Meloidogyne, Pratylenchus, Rotylenchulus, and Helicotylenchus being the most prevalent. Scutellonema sp. occurred in 89% while Tylenchus sp. occurred in 33% of the districts sampled. The ring nematode, Criconemella sp. was found in only two of the nine districts covered; Ketu North and Akatsi South which incidentally recorded 100% of the seven nematodes encountered in the survey. The abundant nematode was Meloidogyne sp. which represented 39% and Criconemella, the least (0.1%) of the total nematodes recovered in the survey. This study has shown that high diversity, incidence and density of economically important plant-parasitic nematodes are associated with sweet potato crop. Development of appropriate management strategies to mitigate the negative effects of plant-parasitic nematodes on sweet potato is recommended.","PeriodicalId":174273,"journal":{"name":"Ghana journal of agricultural science","volume":"136 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-12-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115080954","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}

Seed production activities of 60 seed growers in 26 communities were collected using structured questionnaires, interviews and observations. The Global Positioning System (GPS) coordinates of the communities were geo-referenced to identify the geographical positioning of the production sites. Samples of the groundnut pods were taken from the seed stores, threshed and subjected to seed quality analysis. Descriptive analysis was used to categorize the seed sources, hectarage cultivated, while seed quality data were subjected to analysis of variance of Nested Design. Means of significant factors were separated using Duncan Multiple Range Test (DMRT) at 5% significant level. The study showed that groundnut seed production is better concentrated in regions with optimum and sustainable rainfall that will reduce abiotic stress during seed development like the Lower River Region, West Coast Region and Central River Region.

It examined the extent of balance and the nature of extension delivery with respect to input supplying, production, processing and marketing. A survey of Heads of the Department of Agriculture in 80 MMDAs randomly selected nationwide was conducted using structured questionnaires. The data were triangulated with in-depth interview sessions with farmers, regional extension officers and private extension providers. The study showed a production-oriented nature of extension delivery across the country with 90% of respondents claiming to have focused extension delivery in their localities on production. This had led to the rather inadequate attention directed at processing and value addition on account of limited capacity of agricultural extension agents. While extension on input supplying was observed to be a private sector-driven activity in the hands of input dealers, the study showed limited extension delivery on marketing as most farmers made their own marketing arrangements. This paper makes a strong case for an extension policy that ensures a reasonable balance and one that introduces competitiveness in value chain activities. The paper also calls for sustained institutional capacity building to give providers a more balanced extension delivery.","PeriodicalId":174273,"journal":{"name":"Ghana journal of agricultural science","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-12-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115162378","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}

A lack of balance between the photosynthetic source potential and the sink capacity in terms of dry matter accumulation and distribution is believed to affect fresh tuber yield. This study was aimed to investigate the dry matter production, distribution and tuber yield of reciprocal grafts of some accessions of the Hausa potato. The grafts were made in all possible combinations and laid out using the completely randomized design in four replicates. Results showed that harvest index increased with time in most of the grafts. The proportion of dry matter partitioned to the tubers was generally lower than those of the leaves and stems in all the grafts. The highest rootstock-scion ratio of 0.97 was observed in the graft Bokkos 2 - Manchok 2 while the lowest (0.07) was observed in the self-graft of Bokkos 2. Fresh tuber yield was generally low, ranging from 0.03 t ha -1 to 0.09 t ha-1. Apart from dry matter accumulation and distribution, the relationship between the source potential and sink capacity as well as the rate of translocation of assimilates from the photosynthetic source to the sink need to be investigated.","PeriodicalId":174273,"journal":{"name":"Ghana journal of agricultural science","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-12-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131265256","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 examined the effects of changing agricultural practices on cultivation and availability of indigenous food crops within the basin. Qualitative data obtained from 240 farmers through individual interviews and Focus group discussions were analyzed thematically. The study revealed that even though the farmers employed the traditional mixed cropping system, the widespread use of agro-chemicals in the study area was limiting the practice of intercropping. This accounts for the current dominance of mono cropping system in the study area. These changes have affected the cultivation of a wide variety of indigenous foods within the basin. The uncontrolled use of agro-chemicals constituted one of the major agronomic constraints affecting the cultivation of these crops. Adequate technical support services to effectively control agrochemical abuse among the local farmers will, therefore, be required. Increased sensitization on the need for local farmers to refocus and maintain some of the traditional agricultural practices that ensured the cultivation of a wide variety of indigenous food crop varieties (NUCS) in their farms is also suggested.","PeriodicalId":174273,"journal":{"name":"Ghana journal of agricultural science","volume":"3 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":"122669475","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}
