EFFECT OF NPK FERTILIZATION ON GROWTH AND DEVELOPMENT OF LUFFA (LUFFA ACUTANGULA)
Abstract
This study investigated the effects of NPK fertilization on the growth and development of Luffa acutangula under controlled conditions at Bayero University, Kano, Nigeria. A Completely Randomized Design (CRD) with five NPK treatment rates (0, 30, 60, 90, 120kgha-1 ) and five replications was employed. The result indicated significant improvements in vegetative growth, with 120kgha-1 NPK fertilization yielding the highest vine length, leaf count, stem girth, and chlorophyll content. Root development and biomass (vine fresh and dry weight) also increased with higher NPK rates, though lateral branching remains statistically unaffected. The study concludes that maximum NPK fertilization at 90-120kg/ha optimizes the productivity of Luffa acutangula.
