Effect of humic acid doses on yield and quality parameters of cowpea [Vigna unguiculata (L.) Walp] cultivars

摘要: Present research was conducted to determine the effect of humic acid (HA) on yield and nutritional characteristics cowpea varieties provide an alternative crop for sustainable agricultural systems. Field trials were carried out 2 years in Konya/Turkey ecology. HA applied 4 doses (0, 70, 110 150 kg ha-1 total) (Akkiz Karagoz) a total 20 parameters evaluated. Results showed that, 1000 seed weight, yield, protein potassium manganese increasing tendency by increased dose acid. Furthermore, 70 humicacid recorded higher stomatal conductance first pod height, while applicationof plant height proteinratio. Future related with values is needed achieving better growing techniques mineral composition genotypes.
