Nutrient management is one aspect of tomato farming that most local farmers
neglect to meet. In most circumstances, if not in excess amounts which often goes to
wastage and contributes to high production cost, the fertilizers they apply are
insufficient leading to lagged growth and poor yield. Considering this verity, this study
was conducted to evaluate the performance of tomato with the application of organic
and inorganic fertilizers, at Maglaoi Sur, Currimao Ilocos Norte from January to April
2022. The experiment covered an area of 176 m2. It was laid out in a Randomized
Complete Block Design (RCBD), replicated thrice using Diamante max variety at four
treatment levels namely no fertilizer application, vermicompost, inorganic fertilizer
with recommended rate of 133-210-138 NPK, and inorganic fertilizer with
recommended rate of 93-46-222 NPK. Differences in treatment mean were determined
using the Tukey’s Honest Significant Difference (HSD) test.
Results obtained denote that the application of different fertilizer materials at
varying levels had no significant effects on the growth parameters. The combination of
inorganic fertilizer with recommended rate of 93-46-222 NPK was recorded with the
most prominent effect amongst the four treatments applied resulted to bigger and
heavier fruits and higher number of fruits per hill. Moreover, the use of inorganic
fertilizers, following the recommended rate used enhances the yield attributes of
tomato.
