EFFECT OF CONCENTRATIONS OF ANFAZYME BIOFERTILIZER ON THE GROWTH AND YIELD OF TWO COWPEA VARIETIES

Abstract

This experiment was conducted during the season 2011 to investigate the effect of different concentration (0, 0.25, 0.50, 0.75, 1.00 ml/L) of biofertilizer (anfazym) on growth and yield of two varieties of cowpea, Bonanza and Biader using R.C.B.D design with 4 replicates. Results showed that the concentrations of anfazym , variety and their interaction had a significant effect on growth and yield, but the highest average of plant length, branches and leaves number, Fresh and dry weight , green pods number /plant, yield of pods per plant and hectar achieved at the intraction of 0.75ml/ l of anfazym in Bonanza variety which gave 83.67cm, 7.58 branch, 39.58 leaf, 149.62 g, 34.80 g, 32.50 pod, 10.25 seed , 229.75 gm/plant and 10.83 ton/ha respectively, while the treatment without spray in Biader variety gave 46.25cm , 2.17 branch, 26.67 leaf, 107.86 g, 13.80 g, 17.75 pod, 7.00 seed, 151.25 gm/plant and 7.13 ton/ha respectively.
