Effect of foliar application of urea and naa on yield and yield attributes of chilli (Capsicum annuum Var: Longum)

Abstract

Trial indicated that yield and yield attributes of chilli (Capsicum annuum var. longum) cv. RCH-1 were greatly influenced by the foliar sprays of urea (0.5, 1 and 1.5%) and naphthalene acetic acid (25, 50 and 75 ppm). Increasing concentrations of urea and naphthalene acetic acid increased per cent fruit set, fruit weight, per cent dry yield and yield ha−1 and decreased fruit drop percentage, whereas time taken to 50% flowering was decreased by the higher concentrations of naphthalene acetic acid. The maximwn yield was obtained with the treatment of 1.5% urea and 75 ppm naphthalene acetic acid.
