RESUMO
Integrated soil fertility and soil water conservation technologies are possible solutions to the low per capita food production in Sub-Saharan Africa (SSA). Nonetheless, the rate of adoption of these technologies by smallholder farmers has stagnated over the years despite being recommended. This has been attributed to the existence of wide communication gaps among researchers, extension agents, and farmers. Therefore, this study aimed to assess the influence of communication factors on the adoption of the selected technologies among smallholder farmers in the drylands of Tharaka-Nithi County. We used a cross-sectional survey design and collected data using an interview schedule from 400 randomly selected farming households. Binary logistic regression was employed for data analysis. Results showed that accessibility of extension agents after introducing the technology significantly influenced the adoption of combined organic and inorganic fertilizers (p = 0.056), mulch (p = 0.051), and Zai pit (p = 0.058). Similarly, practical orientation significantly influenced the adoption of combined organic and inorganic fertilizers (p = 0.001), mulch (p = 0.010), and Zai pit (p = 0.003). Information repetition significantly influenced the adoption of combined organic and inorganic fertilizers, mulch, and Zai pit at p-value 0.003, 0.001, and 0.001, respectively. Training was essential for mulch and Zai pit technologies at (p = 0.030) and (p = 0.001) respectively, while farmer group membership significantly influenced adoption for combined organic and inorganic fertilizers (p = 0.045) and Zai pit (p = 0.057) technologies. Extension agents should increase their interactions with farmers after the introduction of technologies. Equally use of demonstrations should be encouraged during the dissemination of these technologies among the farmers as they enhance the chances of adoption of the technologies.
RESUMO
Degraded landscapes and soil water stress are long-standing problems to smallholder agriculture in the drylands. Despite the important roles of zai technology in restoring degraded landscapes and improving agricultural productivity, the technology is yet to be adopted to its fullest extent. This can be attributed to gender-linked disparities in agricultural technology utilization. The study, therefore, sought to determine gender-specific determinants of zai technology choice and use-intensity. A multistage sampling technique was employed in randomly selecting 133 female-headed households and 267 male-headed households in Tharaka South sub-county. Quantitative data were collected in a cross-sectional survey using an interviewer-administered questionnaire. Using sex-disaggregated data, Chi-square and t-test statistic were employed to test the statistical significance of dummy and mean value of continuous variables, respectively. Gender specific determinants of zai technology choice and use-intensity were determined using the Heckman-two-step econometric model. The results revealed that, more women farmers (44%) were using zai technology as compared to men (38%). Among women farmers, total cultivated land, access to animal-drawn farm implements, and group membership had an influence on zai technology choice. For men, total cultivated land, group membership and access to extension services positively influenced choice of zai technology. With regard to zai technology use-intensity, total land cultivated, livestock densities, group membership and frequency of trainings on soil and water management were important determinants among women farmers. For men, zai technology use-intensity was determined by total cultivated land and farmers' perceptions on soil erosion. We recommend that, gender-sensitive farm-level policies oriented towards farmer socioeconomic profiles are important deliberations towards choice and intense application of soil and water conservation strategies such as the zai technology.
RESUMO
Integrated Soil Fertility Management (ISFM) practices are widely recognized as crucial interventions but knowledge-intensive technologies for farmers in Sub-Saharan Africa (SSA). Very few studies have synthesized the knowledge gaps between small-holder practices and recommended ISFM packages. A farm survey was therefore carried out in Runyenjes sub-County of Embu to determine factors influencing the quality of ISFM knowledge considering inorganic fertilizer, organic manure, integrated soil inputs, and improved maize seeds. One hundred small-scale maize farmers were systematically sampled in Embu County, Kenya, using a cross-sectional survey design. The most significant factors shaping the quality of ISFM knowledge (p < 0.05) included gender, age, household size, land under maize, off-farm earnings, maize yield, members involved in farming, farming experience, education level, and farm size. Farmers recorded lower knowledge scores for technical ISFM themes including soil liming, soil testing, fertilizer types, fertilizer functions, curing of organic manure, compost manure management, crop spacing, combination ratios for integrated inputs, and the labor and cost-benefit implications of integrated inputs, revealing important ISFM knowledge gaps. High-quality knowledge of blended fertilizers and DAP use was associated with increased soil testing and soil liming knowledge, respectively. Multivariate analysis of ISFM knowledge items provided a high-quality understanding of the structure of ISFM knowledge among farmers in Embu County, which is useful in developing future ISFM dissemination strategies.
