| Abstract |
A comparative study of apple diseases, microbial and weed diversity was performed in organic and non-organic apple growing fields in Danyang and Muju area during 2012-2013. The result revealed that the populations of microorganisms were initially higher in June at organic I and non-organic sites in 2012. Moreover highest population was recorded in the month of September at all sites. However the population decreased significantly in July at both sites. Individual population of bacteria and fungi increased by the mid of July. This might be due to high rainfall, temperature and humidity. Moreover in 2013, the populations of microorganisum were found higher in May at all sites in 2013. Alternaria leaf spot, Cedar apple rust and Marssonia leaf blight were the major disease in both fields. The disease symptoms were appeared during June. In organic field, Alternaria leaf spot was appeared in August, whereas Marssonia blotch was appeared in September. In organic field Cedar apple rust was appeared in April and May in 2012 and 2013. At the end of rainy season in August, disease symptoms were high due to the spread of disease in the field. There was a variation between the symptoms of disease in two cultivation practices. Weed occurrence was observed from May to September in both 2012 and 2013, and more diverse type of weeds were recorded in the organic cultivation system in comparison to non-organic system.
