Abstract

The study was carried out to examine the influence of organic and inorganic fertilizers on the production of cowpea (Vigna unguiculata) in Taraba State, Nigeria. The specific objectives of the study were among other things, to determine the influence of organic and inorganic fertilizers on the growth rate and yield of cowpea. Three (3) research questions were posed and answered by the study while three (3) null hypotheses were formulated and tested at 0.05 level of significance. Survey research design was used for the study and the study was conducted in Taraba State. The population of the study was two hundred and ninety-one (291) cowpea farmers. The sample for the study was one hundred and sixty-eight (168) respondents comprising sixty (60) organic cowpea farmers and one hundred and eight (108) inorganic cowpea farmers which were obtained using Taro-Yamen's formula. The instrument for data collection was a 17-item structured questionnaire. The instrument was validated by three experts. A reliability coefficient of the instrument was .89 which was obtained using Cronbach-Alpha reliability method. The instrument was administered to the respondents on their farm fields with the help of three (3) research assistants. Mean and standard deviation was used to answer research questions while the hypotheses were tested using t-test at 0.05 level of significance. The findings of the study revealed that at maturity, cowpea produced between 15-35 leaves and has about 3-5 branches. It was equally discovered from the study that, cowpea yield an average of between 400 – 800kg/ha. It was concluded that both organic and inorganic fertilizers when adequately applied using appropriate methods of application can enhance the growth and yield of cowpea.
