Evaluation of some Cultivars of Cowpea ( Vigna unguiculata( L.) Walp) in Growth, yield and Quality


Abstract in English

this study was carried out during summer 2014 in Siano Research Station- the Agricultura Research Center in Lattakia . Four varieties of Cowpea: Dolicho (entrance), Blackey (entrance), Almaarefa (Local) and local cultivar were planted and compared concerning the vegetative growth , productivity and quality of green pods. The results showed the superiority of Almaarefa cultivar in some vegetative traits :plant hieght (166.66) cm compared with local cultivar 116.58 cm ,number of leaves on plant and( 27) leaves and( 17) leaves for local cultivar, and plant leaves area( 7840.23) cm2 for Almaarefa comparing with( 4499.75) cm2 for local cultivar As well as it had a maximum pod length( 16.71) cm and highest grain number of pod( 9.44) ,while Blackey cultivar was the most superior comparing with other cultivars in productivity( 0.6229) kg \ m 2 and pod's number/m2 ( 81.069) Whereas Almaarefa had the lowest productivity( 0.4935) kg/m2 and lowest pod's number ( 65.89)pod/m2. The results also showed that the local cultivar had the most vitamin C content comparing with other cultivars by( 23.765%) and in dry matter by (15.38%) , while there was no significant differences between protein green pods content.
