Determinants of cocoa farmer’s participation in the innovation platform of the humidtropics programme in Southwestern Nigeria
Open Access JournalIn an effort to determine factors influencing cocoa farmer’s participation in innovation platform (IP) activities of the Humidtropics programme, data was collected from purposively selected 177 farmers using multistage technique sampling technique and was gathered through the use of structured interview schedule. Data were collected and analyzed with percentage, frequency counts, mean, standard deviation and factor analysis. The study shows the mean age of the cocoa farmers in the IP to be 51.16±12.64 with about 52% aged above 50 years, female were only (23.73%), with more than 75th percentile literacy level and only about 31% of respondents generate annual income from farming above ₦50,000 while about 70% made below ₦40,000 extra income from other occupation. The mean farm size was 16.87 ±16.04 acre, farming experience 25.42±10.48 years and household size was 9.78±5.52. The six significant determinants of cocoa farmer’s participation in IP arranged in order of magnitude are psychological factor (λ = 3.158), experience factor (λ = 2.164), community related factor (λ = 1.697) educational factor (λ = 1.854), economic factor (λ =1.438) and internal factor (λ = 1.113). The summative effect of the identified factors accounted for 76.17 % variation observed in cocoa farmer’s participation in the IP
Economics of poultry manure utilization in land quality improvement among integrated poultry-maize-farmers in South-western Nigeria
The rapid growth of Nigerian's poultry has made it more advantageous in terms of providing the essential raw material for soil fertility enhancement than other livestock. This paper evaluates the benefits of poultry manure use among integrated poultry-maize farmers in Ekiti and Osun States of Nigeria for improved land quality and continuous food production. Data were collected using structured survey questionnaires administered on 500 randomly selected respondents in the two States. Data were analysed with descriptive statistics and costs and returns techniques. Respondents were small holders, with land area grown to maize varying between 0.01 and 3.00 hectare. Majority of the respondents have personal farms but applied poultry manure only on small portions (25%) of the total cropped area of their farmlands. On the average, 53% of the respondents used poultry manure on their farms. Respondents were fairly literate with a mean age of 43 years. Major constraints to poultry manure use include odour, transportation, scarcity, wetness, bulkiness and time wastage in descending order of importance. While odour and transportation were identified as common problems among poultry manure users in Ekiti and Osun States, bulkiness was an additional constraint for non-user respondents in both states. Poultry manure material constituted about 91% of the total cost of inputs; transportation cost was 8% while labour cost averaged 2%. The mean net income earned per annum by poultry manure users was 1.40 times higher than that for non-users. The difference in mean net income users and non-users of poultry manure constitutes an important land improvement technique capable of enhancing farm production and income levels. Thus, technologies aimed at packaging it in such a way as to remove the associated social constraints to its use by farmers need be put in place.

Incidence and management of plant parasitic nematodes under continuous vegetable production in a rainforest agroecology in Nigeria
Field studies were conducted in 2012 and 2013 in the tropical rainforest zone of Nigeria to investigate the effects of a composted, pelletised organo-mineral fertiliser applied as an organic amendment at 5 metric tonnes (MT) ha–1 or at 10 MT ha–1 in four replications, on soil population densities of five genera of plant-parasitic nematodes and on crop yields of Telfairia occidentalis (fluted pumpkin). The experimental field was naturally infested with Meloidogyne incognita, Tylenchus spp., Helicotylenchus spp., Hirschmaniella spp., and Longidorus spp. The compost was applied as an amendment to soil planted with T. occidentalis 3 weeks after seedling emergence. At the end of both annual experiments, the addition of compost as a soil amendment resulted in 16.25 – 65.75% reductions in the populations of all five genera of plant–parasitic nematodes compared to an increase in each nematode population in the untreated control plots. There was also a higher crop yield of T. occidentalis in all eight treated plots compared to the control plots. Compost applied at 10 MT ha–1 reduced the soil populations of all nematode species significantly, with correspondingly higher yields of the crop compared to 5 MT compost ha–1 in both years of study. Correlation analysis showed that the population density of each nematode species had a negative effect on the cumulative leaf biomass (fresh weight) of the test crop. The results of this study suggest that nematodes constrained the production of T. occidentalis under continuous cropping and that a composted, pelletised organo-mineral fertiliser, applied as a soil amendment at 10 MT ha–1, suppressed soil populations of all five nematodes significantly and increased yields of T. occidentalis by 109 – 366% compared to the untreated control plots
