“…Hence, activities on enhancing the adaptive capacity of the farmers thereby providing different types of improved seeds and conducting participatory research giving emphasis to the PSNP community may reduce the challenge [ 151 , 152 ]. found that participatory approaches are important in selecting traits that meet local needs and its role in improving food security in marginal environments.…”

“…The implication is that strengthening the informal seed system can help smallholder farmers to have access to improved varieties. For example, approaches like crowdsourcing, on-farm trials and farmers' participation during varietal selection and participation could enhance diffusion of improved varieties in one hand and strengthening the formal seed system can also help the farmers to have access to quality seeds in the other hand [ 152 , 153 ]. also recommended farmers’ participation to harness the benefits and selection of genetic resources and indigenous knowledges.…”

“…The area has mainly a semiarid climate with a mean annual rainfall of 912 mm, and the mean daily temperature ranges between 9 °C and 23 °C (Mesfin et al 2022). Agriculture is both rain-fed and irrigation led by small-scale farmers with an average landholding size of less than one hectare per household and it is the mainstay of the economy.…”

Determination of infiltration capacity is a very important parameter during the design and evaluation of irrigation systems. Accurate estimation of infiltration rates helps in optimizing irrigation scheduling, preventing soil erosion, and improving water use efficiency. This study was conducted to evaluate and compare selected infiltration models for estimating water infiltration rates of five soil textures in the Shillanat-iv- irrigation scheme in northern Ethiopia. Soil samples were taken from selected sites in the irrigation scheme to determine soil textural classes using the hydrometer texture laboratory analysis and the USDA textural triangle. A soil textural map of the irrigation area was prepared using the inverse distance weight interpolation technique in ArcGIS version 10.4. The double-ring infiltrometer was used to measure the infiltration rates of different soil textures in the irrigation scheme. Six selected infiltration models namely Kostiakov, Modified Kostiakov, Revised Modified Kostiakov, Philip, Horton, and Novel models were used to estimate infiltration rates for five soil textural classes namely, clay loam, loam, sandy clay loam, clay and sandy loam soils. To evaluate the performance of the models, infiltration rate was measured in 38 points of the study area, out of which 70% of the data was calibrating model parameters and 30% of the data was used for model validation. Parameter values of the infiltration models were optimized using the least-squares errors in SPSS statistical software. Five statistical parameters including the Coefficient of determination (R2), Maximum absolute error (MAE), Bias, Root mean square error (RMSE) and Percentage average error (PAE) were used to evaluate the performance of the infiltration models. Results indicated that the Revised Modified Kostiakov’s, Modified Kostiakov’s, and Novel’s infiltration models had better capability in estimating infiltration rates for clay loam, loam and sandy loam soil textures respectively. Similarly, the Hortons’s model had better performances in estimating infiltration rates of both sandy clay loam and clay soil textures compared to other models. In the design of the irrigation system, the best-fitted infiltration models can be used for estimating the infiltration rate of soil textures in the selected irrigation scheme and other sites with similar soil textures.
