Effect of arbuscular mycorrhizal fungi as fungal biofertilizer on the growth and yield of okra (Abelmoschus Esculentus l.) in Kebbi

Studies on effect of arbuscular mycorrhizal fungi of biofertilizer on growth and yield Okra (Abelmoschus esculentus L).The study was carried out in the greenhouse, the department of biology ADAMU AUGIE COLLEGE OF EDUCATION ARGUNGU in polythene bags (50g). A total of 420 seeds of Okra were collected from national cereals Research Institute Gwadangaji. A sun dried seeds of the samples was sown in polythene bags and distributed into seven treatments which were used in the study as follows, control (without treatment), biofertilizer only, organic fertilizer only, chemical fertilizer only, organic fertilizer + biofertilizer, 20% chemical fertilizer + biofertilizer, and biofertilizer (two doses). Using complete randomized block design (CRBD). From the result shows that the biofertilizer only in all parameters shows significant differences (P< 0.05) compared with the control, which gives an indication that biofertilizer helped plant growth and been able to provide the plants with nutrients as it promoted rapid growth, increased leaf size, leaf length, number of leaves, number of branches, fresh weight and dry weight of the plant, hastened crop maturity, and promote fruit and seed development. It was concluded from the result of the study that a fungal biofertilizer play a role as biofertilizer. Were it is clear that the use of biofertilizer affect the growth of Okra. Biofertilizer (two doses) do not affect the growth of Okra as biofertilizer (one dose).It may be due to competition of fungi. The combination of treatments with biofertilizer were recommended for the optimum growth and the yield of Okra. The experiment may be repeated using another fungi or mixture of different fungi. Potassium solubilizing fungi, phosphate solubilizing fungi or another N-fixing microorganism. Cultivation of the plants in field instead of the polythene bags, to provide an appropriate environment to the fungi.
