"Grain sorghum [Sorghum bicolor (L.) Moench] is the major cereal crop used as staple crop in the arid and\r\nsemi-arid regions of Ethiopia. Low sorghum yields are attributed to soil, climate and topographic factors.\r\nWe investigated sorghum yield response to factorial combination of nitrogen and phosphorous (NP) as\r\nwell as potassium (K), sulphur (S) and zinc (Zn), and how the position of farmers’ fields belonging to\r\ndifferent landscape positions (i.e., upslope, mid-slope, and foot slope) could explain fertilizer response\r\nand yield variability. The analysis in this study made use of dataset from two sets of on-farm experiments\r\nwhere trials were set at two farmers’ fields for NPKS and three farmers’ fields for NPZn experiments in\r\neach landscape position. The experiments were implemented at two sorghum-growing locations (i.e., Hayk\r\nand Sirinka) in parts of the north-eastern Amhara region in Ethiopia. Sorghum yield response to fertilizer\r\napplication was strongly linked to the spatial variation along landscape positions and varied over locations.\r\nFertilizer response was significantly higher at foot slopes compared to mid-slopes and upslope positions,\r\nwhere fields at foot slopes exhibited relatively homogeneous responses. Application of combined nitrogen\r\n(N) and phosphorus (P) fertilizers, landscape position and the interaction of fertilizer application and landscape\r\npositions strongly affected sorghum yield. There was a linear and significant increase in sorghum\r\nyield with the increase in the NP rates. The combined application of NP with different levels of KS as well\r\nas NP with Zn fertilizer rates did not result in significant yield difference. The results indicated that local\r\nfactors were much more influential when accounting for the heterogeneity in sorghum yield response to\r\nfertilizer. This further acknowledges the importance of a landscape-based fertilizer management approach\r\nto respond yield potential variability related with the farmers’ fields and landscape environment. Further\r\ninvestigation is needed to develop homogeneous fertilizer response units based on spatial variability of soil\r\nand topographic attributes along the landscape."^^ . "2022-02-11" . .
