Abstract

BAEZ HERNANDEZ, Alexander  and  HERNANDEZ MEDINA, Carlos A. Study of the yield of Cowpea bean cultivars (Vigna unguiculata (L.) Walp.) in different sowing times in Camajuaní, Cuba. Rev. cienc. tecnol. [online]. 2016, n.26, suppl.1, pp.11-18. ISSN 1851-7587.

This study was conducted in the Intensive Orchard of the Urban Agriculture of the Municipality of Camajuani, province of Villa Clara, Cuba, on brown soils with carbonates of medium to low fertility. The experiment evaluated the yield components in 4 Cowpea cultivars and in 2 sowing times. A design was used in randomized blocks with 6 repetitions. The yields of all the 4 cultivars reaffirmed their possibilities as human and animal food. The yield of the period February-May was significantly lower than through June-September; the weather conditions of scarce precipitation in this last cycle explain this result. The witness cultivar Vinales, followed by Guariba cultivar of certain growth, had significantly superior yield than those of uncertain growth IPA-206 and IPA-207. The yield in the 4 cultivars was determined by the yield component number of sheaths, for all the cultivars in the sowing of the period June-September.
