title: Replication data for: Germination requirements of Allanblackia parviflora seeds and early growth of seedlings

description: This dataset was moved to: https://doi.org/10.34725/DVN/7BFPWLAllanblackia parviflora A. Chev, is an indigenous fruit tree species that could be used in agroforestry systems with both environmental and economic benefits. The seed oil is of prime importance as a foreign exchange earner and is being eveloped as a rural based enterprise in many African countries notably Ghana, Nigeria, Cameroon and Tanzania. Methods for propagation and conservation of the species are therefore of prime importance. The seeds of the species are however difficult to germinate hindering its domestication process. Allanblackia parviflora seeds were collected from seven different populations in Ghana and were subjected to four different seed germination trials at the nursery of CSIR-Forestry Research Institute of Ghana at Fumesua, Kumasi. This was followed by studying the effect of stage of seed germination on establishment after potting. Intact seeds began germination at 7 months after sowing and at 24 months, significant (P\0.001) variations were obse rved in the seed germination ability of 74 accessions. Mean seed germination ranged from 0 to 35%. Significant differences in seed germination percentages among populations (P\0.001) and provenances (P\0.05) were also observed. Removal of seed coat significantly (P\0.001) enhanced seed germination. Germination percentages of seeds with seed coat removed ranged from 6 to 43% while seed germination percentages for intact seeds were less or equal to 3%. Incubation of seeds with seed coat removed in polythene bags gave an added advantage. Seeds with seed coat removed and kept in polythene bags started germinating from 2 weeks and within 10 months, 75 and 68% germination were obtained for plane and black polythene bags, respectively. Removal of germinants and potting when shoot length was at least 1 cm gave significantly higher growth (P\0.001 for shoot height, P\0.05 for stem diameter, P\0.001 for number of leaves produced) compared to when only radicle had emerged. It became evident in this study that seeds should be classified as fully germinated only when shoots begin to grow.

title: Replication data for: Integration of legume trees in maize-based cropping systems improves rain use efficiency and yield stability under rain-fed agriculture

description: This dataset was moved to: https://doi.org/10.34725/DVN/FUZDMUWater availability is a major constraint to crop production in sub-Saharan Africa (SSA) where agriculture is predominantly rain-fed. This study aimed to investigate the effect of the nitrogen-fixing legume tree Leucaena (Leucaena leucocephala) and ino rganic fertilizer on rain use efficiency (RUE), a robust measure of productivity and land degradation, in three long-term (11–12 years) experiments conducted in Zambia and Nigeria. On the two Zambian sites, sole maize (Zea mays) grown continuously (for 11–12 years) with the recommended fertilizer achieved the highest RUE (3.9–4.6 kg ha−1 mm−1) followed by maize intercropped with Leucaena (2.5–3.4 kg ha−1 mm−1). This translated to 192–383% increase in RUE over the control (maize grown without nutrient inputs), which is the de facto resource-poor farmers’ practice. RUE was more stable in fully fertilized sole maize on the first Zambian site and not statistically different from the maize–Leucaena associations on the second site. On the Nigerian site, RUE was higher in maize planted between Leucaena hedgerows supplemented with 50% of the recommended fertilizer (3.9 kg ha−1 mm−1), maize grown between Leucaena hedgerows without fertilizer (3.0 kg ha−1 mm−1) and sole maize receiving the recommended fertilizer (2.8 kg ha−1 mm−1), which translated to increases in RUE of 202%, 139% and 85%, respectively, over the control. RUE was more stable in the maize grown between Leucaena hedgerows than in the fully fertilized maize. On all sites RUE was least stable in the control. Yield stability in the maize–Leucaena association was not significantly different from the fully fertilized maize on the Zambian sites. On the Nigerian site, maize yields were more stable in maize grown in Leucaena hedgerows than in fully fertilized sole maize. Supplementation of maize grown in Leucaena hedgerows with 50% of the recommended fertilizers resulted in greater yield stability. It is concluded that intercropping cereals with legume trees and supplementation with inorganic fertilizer can increase rain use efficiency and yield stability in rain-fed agriculture in SSA.

title: Replication data for: Human health and occupational exposure to pesticides among smallholder farmers in cotton zones of Côte d'Ivoire

description: This dataset was moved to: https://doi.org/10.34725/DVN/IYKEKPWhile precautionary efforts are being made to minimize human health problems associated with agricultural pesticides, the continued occurrence of occupational poisoning from these chemicals raises major concerns among stakeholders. Information gap on human health problems associated with pesticides poses major obstacles to making informed policy decisions, particularly in developing countries where most of the poisonings occurs. In this study, we identified acute human health symptoms associated with pesticide use in cotton zone of Côte d’Ivoire and, documented the response of rural households to the symptoms. The results show that cotton farmers in Cote d’Ivoire suffer from different occupational health hazards from expo-sure to agricultural pesticides. Key health symptoms reported by pesticide applicators are headache, rheum, cough, skin rash and sneezing. Pesticide applicators reported four times higher symptoms of ill health than other house- hold members who do not nor mally handle pesticides. Although, households recognized pesticides as an important cause of ill health, some of the symptoms have been accepted as norm by individuals who apply pesticides. Official data on pesticide poisoning in the country is most likely to be seriously under-estimated as applicators visited formal health centers for medical assistance in only 2% of poisoning cases reported. There is a high likelihood that households in the study area under-estimated pesticide-related health costs in making farm production decision-making. Approaches to use economic instruments for reliable monitoring and reporting procedures to formulate appropriate policies and regulations to minimize exposure to pesticides are recommended. Health planners and policy makers should aim at reducing the risks posed by pesticide to farm households by, improving awareness of farmers; promote complementary approach (e.g. Integrated Pest Management) and, use of economic instruments and improved surveillance to bridge the gap in the documentation of pesticide poisoning cases among farmers.

title: Replication data for: The Dynamics of Public Confidence in U.S. State and Local Government.

description: While the dynamics of trust in the national government have been shown to be responsive to political events and governmental performance, less is known about why the public’s trust in U.S. state and local government rises and falls over time. We examine the trends in confidence in subnational government using an aggregate level approach. First, we consider whether levels of trust are defined by reactions to the national government. Second, we consider how factors specific to subnational politics such as governmental performance and the quality of community life influence trust. Using measures of confidence in state and local government from 1968 to 2004 and a set of error correction models, we find evidence for both accounts. Confidence in subnational governments reflects national trends such as economic tides and public preferences for more or less government, but also exhibits unique dynamics explained by factors specific to subnational politics.

title: Ethnobotanical and socio economic study of some medicinal plants used in cancer treatment in the Boyo division in highland region of Cameroon: Lannea kerstingii, Geniosporum rotundifolium, Entada abyssinica and Ocimum gratissimum

description: This dataset was moved to: https://doi.org/10.34725/DVN/OANZC4An ethnobotanical and socio-economic study of some four medicinal plants used in cancer treatment was carried out in the Boyo Division of the northwest region of Cameroon from the 1st of April to the 31st of September 2010. The main objective of the study was to assess the use and evaluate the importance of Lannea kerstingii, Geniosporum rotundifolium, Entada abyssinica and Ocimum gratissimum to different user groups in the Boyo Division. Two sets of questionnaires were structured and addressed to 30 traditional healers and 60 household heads. Data collected were analyzed using EXCEL 2007 and SPSS v. 12. Results show that 100% of respondents have some knowledge about O. gratissimum, while the least known medicinal species is L. kerstingii (known by 32.22% of respondents). The total percentages of those who know E. abyssinica and G. rotundifolium are 74.44% and 91.11% respectively. The main plant parts used for the shrubs are the leaves (with 72.1%) citations for O. gratissimum and 51.7% citations for G. rotundifolium), while for the tree species, the major plant part used is the tree bark (cited by 70.6% and 69.1% of users for L. kerstingii and E. abyssinica respectively). The main sources from which the species are harvested include the wild and home gardens. Those involved in collecting the plant species are the men, (22.4%) women (46.3%) and young people (31.3%). Apart from O. gratissimum which has been cited by the majority of respondents (70.59%) as being constant over the past few years, all the other species have been decreasing as cited by the majority of respondents (95.74%, 85.00% and 84.48% for L. kerstingii, E. abyssinica and G. rotundifolium respectively). Respondents attest there is a problem of scarcity and the causes of scarcity include amongst others, bush clearance for agriculture and construction, the drying up of plants during dry season, dry season bush fires, overharvesting, and slash and burn agriculture. The number of cancer patients received by traditional healers per month varies from 1 to 100 patients and the average cost of treatment is estimated at 23960FCFA. This study recommends: to ICRAF, to encourage cultivation of medicinal species through participatory tree domestication; to users of medicinal plants, to engage in sustainable harvesting practices, and to the government, to formalize the market for the medicinal plants as well as for the services provided by traditional healers.

title: Replication data for: Calorific value of Prosopis africana and Balanites aegyptiaca wood: Relationships with tree growth, wood density and rainfall gradients in the West African Sahel

description: This dataset was moved to: https://doi.org/10.34725/DVN/BHNFLHProsopis africana and Balanites aegyptiaca are native tree species in the West African Sahel and provide wood for fuel, construction and other essential products. A provenance/progeny test of each species was established at one relatively dry site in Niger, and evaluated at 13 years. Gross calorific value of the wood was determined for a random sample of trees in each test: gross CV and CVm3 = gross calorific value in MJ kg−1 and MJ m−3, respective ly. The major objectives were to determine if gross CV was positively correlated with wood density and tree growth, and if gross CV and/or CVm 3 varied with rainfall gradients in the sample region. Provenances were grouped into a drier and more humid zone, and correlations were computed among all trees and separately in each zone. Results indicated that gross CV was not significantly correlated with density in either species. Gross CV was positively correlated with growth of P. africana (but not B. aegyptiaca) only in the drier zone. Gross CVm3 was positively correlated with growth of b oth species, and the correlations were stronger in the drier zone. Multiple regressions with provenance latitude, longitude and elevation indicated that provenance means for gross CV increased, in general, from the drier to the more humid zones. Regressions with gross Vm 3 were not significant. Results are compared with earlier research reports from the provenance/progeny tests and with other tropical hardwood species; and practical implications are presented for tree improvement and conservation programs in the region.
