The introduction of cowpea gives an opportunity to use the crop for agricultural production, for fodder production and for the introduction of the new and useful food product. Nowadays there is definite information on the biology, agromachinery and use of cowpea that promoted developing the basis for cowpea breeding. The variety samples of asparagus beans showed a significant interaction of 'genotype-environment' of the studied traits excluding the duration of the interphase period
