EFFECT OF NITROGEN APPLICATION METHODS ON THE GROWTH AND YIELD OF RIDGE GOURD (LUFFA ACUTANGULLA)

Abstract

Study was conducted In RCBD Design with three replicates to examine the impact of nitrogen application methods on the growth and yield of ridge gourd, evaluating 06 treatments comprising of various soil and foliar-applied N combinations. The following treatments were used: T1=Control (no N applied to the surface, no N applied to the leaves): T2=N at 75kg ha^-1 through soil; T3=N at 75 kg ha^-1 through soil+foliar urea at 1.5% concentration; T4=N at 75 kg ha^-1 through soil+foliar urea at 3.0% concentration; T5=N at 100 kg ha^-1 through soil; T6=N at100 kg ha^-1 through soil+foliar urea at 1.5% concentration;T5=N at 100 kgha-1through soil+foliar urea at 1.5% concentration; The findings showe that various nitrogen application approaches had a major impact on all of the ridge gourd parameters calculated in this analysis (P0.05).
