Summary: | The response of corn single cross 640 to chemical fertilizers, biofertilizers and their interactions were studied. The experiment was conducted as a factorial arranged in completely randomized block design with three replications. Treatments consisted of combined application levels of urea fertilizer at five levels (0, 75, 150, 225 and 300kg pure nitrogen per hectare as urea fertilizer) and two levels of biological fertilizer (inoculated and non-inoculated). The results showed that the interaction of biofertilizer with urea fertilizer had significant effect on traits such as grain yield, number of grains per ear and thousand grain weight and plant height. The highest grain yield (10425.14 kg.ha-1) was obtained with 300 kg urea and inoculated with biological fertilizer and the lowest (5712.49 kg.ha-1) grain yield obtained in control level (no urea fertilizer) and non-inoculated with biological fertilizer. There is no difference between biological fertilizer with 225 kg of urea and biological fertilizer plus 300 kg of urea related to grain yield. It seems that the combination of chemical fertilizers with organic fertilizers can produce maximum yield that due to provide nutrients for plants. |
