Comparative effects of the combination of biofertilizer, NPK, and mycorrhizal application on maize production system

The use of uncontrolled an-organic fertilizer continuously will degrade soil fertility and nutrients balance. To minimize those impacts, biofertilizers and an-organic fertilizer are needed to maintain a sustainable maize production system. The study used a randomized complete block design with 3 replications with different levels of fertilizer application, conducted at University of Brawijaya experimental research station at Jatimulyo-Malang-East Java. Several parameters were measured to examine those effects on soil and crops. The treatments affect crop height, leaf chlorophyll indices, leaf area indices, maize yields, total number, and mycorrhizal infection. The best treatment was detected under the combination of 100% biofertilizer and 100% NPK, along with the addition of 100% microelements. The lowest was observed under mycorrhizal applications. There was a positive correlation between chlorophyll, crop height, leaf area, and maize yields.
