Interactive Effect of Phosphorus and Potassium on Growth, Yield, Quality and Seed Production of Chili (Capsicum annuum L.)

Abstract

Phosphorus (P) and potassium (K) play an important role in growth of chili. An adequate amount of P and K exerts significant effect on the growth, yield, quality and seed production of this crop. To evaluate suitable dose of P and K for different growth, yield, quality and seed production parameters of the exotic land race of chili which was brought from Spain (paradon), and aim to improve it through selection under environmental conditions of Rawalakot. An experiment was laid out in randomized complete block design (RCBD) with eight different treatments. Maximum plant height (53 cm), number of branches per plant (41.20), number ofleaves per plant (340.8), number of flowers per plant (90.83), number of fruits per plant (30.17), fruit length (9 cm), fruit girth (13.03), weight of fruit per plant (465.5 g), weight of 1000 seeds (6.93 g), acidity (169.67 mg g-1) and Phosphorus percentage (0.3153) was observed in T3 when applied 100 kg ha-1 of P and 120 kg ha-1 of K. Best results regarding most of the growth, yield and quality parameters of chili crop was observed in T3 therefore, combined application of 100 kg ha-1 of P and120 kg ha-1 of K could be recommended to farmers for best growth and yield of this crop under agro climatic conditions of Rawalakot.
