DOLJANA, A NEW VARIETY OF COWPEA (Vigna unguiculata L.Walp.) RECOMMENDED ON SANDY SOILS
Journal Title: ISB-INMA TEH AGRICULTURAL AND MECHANICAL ENGINEERING - Year 2017, Vol 0, Issue 1
Abstract
The new variety of cowpea, Doljana, was created at the Development Research Center for Agricultural Plants on Sands, Dabuleni, in the field of cowpea amelioration and registered in the Official Catalog starting with 2017. This variety was obtained by repeated individual selection in a natural hybrid of cowpea population. Doljana is a cowpea variety highly resistant to pathogens and tolerant to pest and has a high productivity and an early age of about 11 days compared to the Jiana variety. The Doljana variety,performed an average yield of 2697 kg / ha over a period of 8 years, with a production difference of 893.4 kg / ha, compared to the Jiana variety, very statistically significant. Also, compared to the witness variety, Jiana, the Doljana cowpea variety records an early harvest of about 11 days and a higher ecological plasticity. The grain yield obtained from the cowpea has varied according to the climatic conditions of the years of study. Thus, there were significant positive correlations between the cowpea production and the average air temperature of the cowpea growing season (May-August) and insignificant correlations between the precipitation regime and the production obtained.
