NERICA intercrop systems and their influence on yield components and productivity of NERICA and partner crops in the Guinea Savannah Zone of Ghana.

摘要: The purpose of the study was to evaluate sustainability upland rice “New Rice for Africa” (NERICA) based cropping systems in order recommend improved crop production technologies farmers Guinea Savannah Zone (GSZ) Ghana. On station experiments were carried out during 2010 and 2011 seasons at trial fields CSIR-Savanna Agricultural Research Institute, Nyankpala, Two cultivars each four crops evaluated partnership with NERICAs 1 & 2. design a split-split plot arrangement. main factors NERICAs, while sub-plot NERICA partner –viz: two (cvs.) maize cvs. Dorke SR Dodzi, cowpea Marfo tuya Apagbala, soybeans Jenguma Quarshie pepper Shito adope Akonfem. A factorial combination resulted 16 treatments which arranged randomized complete block 3 replicates. results indicated that agronomic parameters such as plant height (cm), number panicles per meter squared, grain weight (kg/ha) Land equivalent ratios (LERs) significantly affected by intercropping selected crops. No significant differences however, observed attributable effects on yields yield components LER estimates that, comparison (N) intercrops, N1 produced more than N2 same partners. Economic analyses demonstrated most sustainable intercrop N1` cv. Akonfem (net benefit 976 Ghana cedis (GHc) hectare B:C ratio 52%).The least tenable GHc -242 -13%). For NERICA1 farmers, preferred system should be (cv. Akonfem), NERICA2 consider (cv.Shito adope).
