Highlights:

Mango production for the last 6 years (2009-2014) (BAS data) has declined as to production in metric tons and yield per hectare from 293,993 MT in 2009 to 271,091 MT in 2014. With the existing challenges affecting the mango industry in the region, there is a need to address safe and quality produce, not only for human and its consumption but also environmental sustainability. This research study was conducted in Ilocos Integrated Agricultural Research Center (ILIARC) in Bacnotan, La Union from March to June 2016. It aims to evaluate the efficacy of different organic solutions as alternative inputs, determine the macro and micro elements content of the different organic solutions to be used in mango production, and determine the economic benefits of producing mangoes using different organic solutions.

Results of the study using different organic solutions such as fermented distillery waste, cultured yeast and wood vinegar as compared to chemical pesticides shows no significant difference on percentage panicle development, panicle length, anthracnose incidence, fallen fruits, fruit sizes, and yield. However, natural enemies population were not much affected as compared to chemical spraying as evidence by the presence of spiders and wasps. Anthracnose incidence was even recorded lower on treatments used with organic solutions. It has even reduced cost of production at least 15% as compared to chemical spraying. This relates to the potential effect of the organic solutions as alternative inputs that farmers may opt to use in producing chemical pesticide-free mango. Pangasinan as the largest producer contributing to the 25% (212,366 MT, PSA-BAS, 2014) share to the national production can be one of the initial potential adoptors of the technology. Aside from producing safe fruits for human consumption, it may avoid human exposure to the danger of toxic that threatens life including soil microbes and maintain the ecological balance.

However, with the existing conditions of the experimental sites wherein trees had a closer distance, poor sunlight penetration and air circulation affected the trees in producing low yield making the area favourable to pests and diseases. Pruning and bagging have to be considered in producing quality fruits. At the end, it is recommended that another field trial should be conducted in an orchard type mango plantation in the region.
