“…Discussion. The yield performance of a given crop largely depends on the climate, soil conditions and on-farm management practice 3,5,8,11,15,16 . From our study of the 17 trial farms, soil characteristics account for 73% of suitability scores where the climate was less favorable for cassava cultivation.…”

“…At Mokwa, Central Nigeria, both the climatic parameters and the soil resources are pertinent to achieving an average cassava yield above the world average (11.1t ha −1 ). With our cassava clone (TMS98/0505), any location with optimal soil conditions and favorable climatic conditions (characterized by the long daily sunshine hour) is favorable 3 . By observing the yield performance and suitability rating of the locations (Figs.…”

“…Thus, cassava farming would strive where viable irrigation scheme is available in Northern Nigeria. Moreover, the observed variability in edaphic suitability proffers that soil-related constraints are field-specific, so also the required intervention 3,52,53 . Therefore, a need to revolutionize farming system in Nigeria is sacrosanct.…”

To investigate the optimal cultivation conditions for cassava cultivar (TMS98/0505) in Nigeria, we employed agro-ecological zoning to delineate the cultivated lands. Using GiS-based multi-criteria analysis, we researched the influence of some meteorological and soil parameters on the clone cultivation. From the multiple-parameter climato-edaphic zoning map, an average yield of 26 t ha −1 was estimated. The dry Rainforest and southern Guinea Savanna account for 80% of the favorable zones. However, with irrigation, the cultivar would yield optimally in the northern marginal zones. Further, the significant climatic parameters are sunshine hour (t = 3.292, α = 0.0064) and rainfall (t = 2.100, α = 0.0575). Thus, the potentials of a location for cassava cultivation in Nigeria largely depend on the soil conditions, sunshine hour, and rainfall. Generally, the cassava yield correlates strongly (+0.88) with the suitability map. Considering future climate variability based on the annual rainfall data, we projected an average annual rainfall range of 565-3,193 mm between 2070 and 2099. Likewise, the projected range of daily temperature for 2046-2100 is 24.57-31.94 °C. Consequently, with currently allotted farmlands, nigeria can double her current cassava production through soil fertility enhancement and irrigation.

<p>The low soil fertility is one of the causes of the reduction in cassava production in the Nuabosi area of Ende Regency. Therefore it is necessary to identify soil fertility and farmer activities on the land. This research used survey system by takes soil samples and farmers from ten fields in five villages, namely Ndetundora I, Ndetundora II, Ndetundora III, Embuteru and Randotonda. Determination of land were used purposive sampling method. Whereas farmer activity data is obtained by interviewing farmers whose land is used as land sampling. Variables observed were physical and chemical soil properties. The results of the analysis of agricultural activities can be described using existing theories. While the analysis results of the physical and chemical properties of the soil can be described using chemical criteria and soil fertility from the Bogor soil research center. The results of interviews and direct observations in the field showed that Nuabosi cassava farmers did not only plant cassava but also used conservative agricultural on their land. The physical properties of the soil analyzed showed that the soil was suitable for cassava plants. Based on soil fertility criteria, these lands have a limiting factor for C-Organic.</p>
