Efficiency of Legumes in Increasing Yam Yield under Sandy Ferrasol in the Forest Zone of Southwestern Côte d’Ivoire

Open Journal of Soil Science 2024年第4期14卷 227-236页

Ettien Department of Soil Sciences Water and Geomaterials University of Felix Houphou&#235t Boigny Abidjan C&#244te d&#8217Ivoire Department of Food Security and Nutrition Swiss Center for Scientific Research in C&#244te d&#8217Ivoire Abidjan C&#244te d&#8217Ivoire

The cropping system is b.sed on traditional farming in rural areas. In this way, yields of some food crops like yam are very low considering their high need for nutrients. The nutrient-rich land is under high land pressure as it is occupied b. cash crops such as oil palm and rub.er at the expense of food crops and soil fertility is declining. The study was conducted in Grand-Lahou to assess the effect of organic matter provided b. legumes in increasing yam yield. The randomized complete b.ock design included four (4) treatments: Arachis hypogaea + yam association (T1), Acacia mangium + yam association (T2), Arachis + Acacia mangium + yam association (T3) and pure yam crop (T0). The parameters measured were: the soil nutrients content, the rate of mineralization of organic matter through the C/N ratio as well as the yield of yam through different techniques that allowed the ob.ective of the study to b. achieved. It was noted a slight improvement of nitrogen and organic carb.n in all treatments with a higher value recorded in the T2 treatment. The C/N ratio decreased to 12 in all treatments compared to the control, which reflects a normal decomposition of the organic matter. Treatment T1 increased yam yield (8.4 t/ha) in contrast to treatments T2 (4.1 t/ha) and T3 (2.8 t/ha). Legume-b.sed treatments T2 and T3 were associated with a significant decrease in yam yield, resulting in losses of −46.34% to −25.09%, while treatment T1 resulted in a gain of 28.57%. As a result, the treatments involving legumes contrib.ted to normalizing the organic matter content of the soil. The simultaneous association of these two legumes led to a decrease in yam production, contrary to the treatment associating only groundnut.

Characterization of Small-Scale Farmers and Assessment of Their Access to Crop Production Information in Selected Counties of Kenya

引用

Agricultural Sciences 2024年第5期15卷 565-589页

作者： Anastasia Mumb. Wahome John b. K. Kiema Galcano C. Mulaku Isaac Mukoko Department of Geospatial & Space Technology University of Nairobi Nairobi Kenya Department of Pub.ic Health Kenya Methodist University Nairobi Kenya

Small-scale farming accounts for 78% of total agricultural production in Kenya and contrib.tes to 23.5% of the country’s GDP. Their crop production activities are mostly rainfed sub.istence with any surplus b.ing sold to b.ing in some income. Timely decisions on farm practices such as farm preparation and planting are critical determinants of the seasonal outcomes. In Kenya, most small-scale farmers have no reliab.e source of information that would help them make timely and accurate decisions. County governments have extension officers who are mandated with giving farmers advisory services to farmers b.t they are not ab.e to reach most farmers due to facilitation constraints. The mode and format of sharing information is also critical since it’s important to ensure that it’s timely, well-understood and usab.e. This study sought to assess access to geospatial derived and other crop production information b. farmers in four selected counties of Kenya. Specific ob.ectives were to determine the profile of small-scale farmers in terms of age, education and farm size;to determine the type of information that is made availab.e to them b. County and Sub.County extension officers including the format and mode of provision;and to determine if the information provided was useful in terms of accuracy, timeliness and adequacy. The results indicated that over 80% of the farmers were over 35 years of age and over 56% were male. Majority had attained primary education (34%) or secondary education (29%) and most farmers in all the counties grew maize (71%). Notab.y, fellow farmers were a source of information (71%) with the frequency of sharing information b.ing mostly seasonal (37%) and when information was availab.e (43%). Over 66% of interviewed farmers indicating that they faced challenges while using provided information. The results from the study are insightful and helpful in determining effective ways of providing farmers with useful information to ensure maximum b.nefits.
