Lakatan banana is an economically important fruit crop in the Philippines. It's aroma and sweetness when ripe makes it is a popular local dessert. It can grow in a wide range of soil and environment, but proper management is key to profitable production. The growth, yield and fruit quality are prevalent weather. Phonological studies are essential for monitoring the impacts of environment and climate change particular, but these are wanting local tropical crops like Lakatan banana. Field experiment was established at the Central Experimental Station of UPLB [University of the Philippines Los Bañnos] to determine the effect of irrigation and different fertilizer treatments on the growth and yield of Lakatan. The experiment followed the split plot design with five replications with Irrigation as the main plot and fertilizer as sub-plot. Automatic weather station and field sensors monitor the prevailing microclimate in the experimental area. Regardless of treatment, rate of leaf emergence was lower during the dry months. Banana has a predefined number of leaves before flower emergence and fruiting is terminal. Thus, a delay in leaf emergence translate into a delayed flowering. Under uncertain weather conditions, longer exposure in the field increases the risk of being affected by stressors, including typhoons and pests and diseases. Pseudostem girth which in previous studies has shown strong correlation with bunch yield peaked at 135 DAP, across all treatments, but similar with other growth parameters plant height and number of green leaves were higher in irrigated with high fertilization treatment. For the same growing degree days (GDD), irrigated with high fertilization rate produced more leaves compared with the other treatments.
