Yield Comparisons of Mung-bean as Affected by Its Different Nutritions (Chemical, Biological and Integration) under Tillage Systems

To compare yields of mung bean under different nutrition (Chemical, Biological and Integrated) and tillage systems a split plot experiment based on a randomized complete block design with three replications was conducted in 2015. Treatments consisted of 3 levels of tillage systems (no-tillage, conservation tillage and conventional tillage) and 4 levels of plant nutritions (inoculated with mycorrhiza + 50% nitrogen, 50% nitrogen without mycorrhizal inoculation, mycorrhizal inoculation +100 percent nitrogen, without inoculation with mycorrhiza + 50% nitrogen). The results showed that plant nutrient sources affected yield significantly. The highest grain yield (1510.03 kg.ha-1) was obtaind by using conservation tillage, 50% nitrogen and mycorhizal seed inoculation. This yield was 50% more than conventional tillage and nitrogen fertilizer and mycorrhizal seed inoculation which was 934.1 kg.ha-1. The highest protein yield (24.99 kg.ha-1) belonged to conventional tillage, 50 percent of nitrogen use and mycorrhizal inoculation, which is 100% (13.33 kg.ha-1) more than conventional tillage and nitrogen fertilizer with 50 percent of mycorrhizal inoculation. In general, the results showed that the use of tillage did not have significant effect on most of the traits. This result could be different if this experiment would be continued for several years. These results indicated that mycorrhizal seed inoculation reduced the need for nitrogen fertilizer, while increased seed yield.
