Comparative Effects of Biofertilizers, Chemical Fertilizer and Fungicide on Growth of Brassica nigra

The present study examined the outcome of biofertilizers, chemical fertilizer and fungicide alone and in combinations on growth and biochemical parameters of Brassica nigra at the 30th and 60th day of germination. Result showed significant enhancement in growth and biochemical parameters of plants as compared to control plants. Trichoderma hamatum and rhizobial isolates treatments alone and in combination with each other and with chemical fertilizer were found effective in improving the shoot and root lengths, total chlorophyll, carbohydrate, crude protein, and mineral (nitrogen and phosphorus) content of Brassica nigra. It indicates that biofertilizers alone and in combination enhanced total carbohydrate, protein and nitrogen contents may boost the soil fertility by improving its organic and inorganic content. Therefore, biofertilizers could be a good alternate of chemical fertilizer and fungicide for improving the growth and productivity of Brassica nigra.
