Foliar Application of Alpha-Naphthalene Acetic Acid (ANAA) and Inorganic Fertilizer on Yield and Yield Components of Visayan White Corn at Horticultural Maturity

Abstract

Research on optimizing the use of fertilizers and plant growth regulators has become essential in the quest to increase agricultural output. The native Philippine maize variety known as Visayan white corn, or Tinigib, offers a chance to investigate these developments. Improper application techniques for growth regulators and inadequate fertilizer frequently make it difficult for farmers to maximize productivity. The challenge is finding the exact mixtures and dosages that can greatly improve crop production without suffering from negative side effects. This study aims to address this gap by evaluating the effect of foliar application of alpha-naphthalene acetic acid (ANAA) combined with inorganic fertilizer on the yield and yield attributes of Visayan white corn at horticultural maturity, employing a randomized complete block design with five (5) treatment and (3) replications. Results revealed that Treatment no. 2, composed of 20 ml ANAA and RR NPK, was concluded to yield the highest corn output, showcasing the efficacy of combining ANAA with inorganic fertilizer to enhance yield.
