Evaluation of Yield and Yield Components of Some Cowpea (<i>Vigna unguiculata</i> (L.) Walp) Genotypes in Forest and Transitional Zones of Ghana

Cowpea adapts very well to environmental conditions that normally affect production of crops such as drought, temperature changes and other stresses. However, apart from these attributes, the growth development some cowpea genotypes especially during flowering stage yield are affected by drought high temperatures. Two field trials were conducted at two different locations (Mampong Fumesua) in 2015 2016 growing seasons evaluate stability eight varieties (Asontem, Tona, Nhyira, Videza, Asomdwe, Asetenapa, Soronko Tona) released over decades ago CSIR-CRI forest transitional zones Ghana. The experimental design used was a Randomized Complete Block Design with three replications. results revealed Asontem, Tona Nhyira had yields both across seasons. Asontem showed superiority amongst Asetenapa having lowest yields. temperatures, hence Asetena low compared genotypes. It is recommended that, for farmers get more profit due unpredictable climatic prevailing Ghana, it will be profitable grow early maturing cowpeas can stable environments order good returns.
