“…Our results are consistent with other studies that considered high yields, resistance to diseases, and lower price as main drivers for selecting improved seeds (Asrat et al, 2010;Sibiya et al, 2013;Waldman et al, 2017).…”

Appropriate technologies must be developed for adoption of improved seeds based on the farmers' preferences and needs. Our research identified the farmers' willingness to pay (WTP) as a key determinant for selecting the improved varieties of maize seeds and landraces in Chiapas, Mexico. This work also analyzed the farmers' observed heterogeneity on the basis of their socio-economic characteristics. Data were collected using a semi-structured questionnaire from 200 farmers. A proportional choice experiment approach was applied using a proportional choice variable, where farmers were asked to state the percentage of preference for different alternative varieties in a choice set. The generalized multinomial logit model in WTP-space approach was used. The results suggest that the improved seed varieties are preferred over the Creole alternatives, thereby ensuring higher yields, resistance to diseases, and larger ear size. For the preference heterogeneity analyses, a latent class model was applied. Three types of farmers were identified: innovators (60.5%), transition farmers (29.4%), and conservative farmers (10%). An understanding of farmers' preferences is useful in designing agricultural policies and creating pricing and marketing strategies for the dissemination of quality seeds.

Double blind field experiments and experimental auctions were conducted with bean and cowpea farmers in Tanzania and Ghana to gauge the relative demand for three types of seed products that differ in price and quality: certified, quality declared, and recycled. Whether the cost differential makes these seeds qualitatively different products as reflected in their perceived performance, and whether that translates into farmers' willingness to pay price premiums, are the research questions addressed by this study. Results indicate that, all else equal, there were significant differences in the perceived quality of the seed products evaluated. Farmers were willing to pay significantly more for their higher rated seed relative to their lower rated seeds. However, for a majority of farmers the magnitude of the premium they are willing to pay for a higher quality seed is less than the current price differential between certified seed and grain. Research and policy implications of these results for legume seed system are discussed.

“…Temporal compatibility of maize and soybean has been observed previously by Agyare et al (2006), Snapp et al (2002), andvan Vugt et al (2018). Evidence from a logit link analysis of crop preference in central Malawi revealed that female farmers in particular express strong interest in producing and marketing soybean and generally have access to improved soybean seed (Waldman et al, 2017). Taken together, there are multiple lines of evidence that soybean rotated with maize is a farmer-preferred treatment with high adaptation to weather and edaphic variability.…”

Functional crop diversity enhances crop productivity, stability, and food security through efficient nutrient cycling and water utilization; however, performance is variable under marginal environments. We applied stability analysis to assess impacts of grain legume integration on maize (Zea mays L.) grain yield, yield stability, N use efficiency (NUE), and ability to meet household protein requirements. Six field trials were conducted across three agroecological zones over five cropping seasons. We used additive main effect and multiplicative interaction to assess grain yield stability of maize in unfertilized maize, maize fertilized with 69 kg N ha−1 (Mz69), maize–pigeonpea [Cajanus cajan (L.) Millsp.] intercrop (MzPp), and maize in rotation with soybean [Glycine max (L.) Merr.] (SbRot), peanut (Arachis hypogaea L., PnRot), and peanut–pigeonpea intercrop (PnDLR). Maize in rotation or intercrop received 10.5 kg P2O5 and 35 kg N ha−1, whereas the Mz69 treatment received 21 kg P2O5 and 69 kg N ha−1. Maize grain yield in rotation with legumes was not significantly different from yield for Mz69. In wetter environments, MzPp intercrops had low maize grain yield (−35%) relative to Mz69, whereas in drier environments, maize had higher grain yield (14%) relative to rotated maize. Rotating maize with legumes increased NUE (56%) and protein contributions (65%) relative to Mz69. Grain yield of maize in SbRot consistently had the highest yield and was the most stable technology. Simple statistical models can be used to test multicrop stability. Integrating maize with legumes as intercrops or rotation can allow farmers to achieve high and stable yield under varying rainfall, with modest fertilizer investments.
