Impact of bio stimulants on growth parameters of capsicum (Capsicum annum L.)

Abstract

In recent years, there has been a growing interest in the cultivation and consumption of peppers, prompting efforts to identify optimal conditions for their growth and development. This study aimed to assess the impact of biostimulants on the growth and yield of capsicum. The experiment involved twelve treatments, including an absolute control, and was designed using a Randomized Block Design with four replications. The underlying hypothesis suggested that biostimulants could enhance the yield of pepper fruits. The study was conducted in a polyhouse at the Department of Vegetable Science, CCS Haryana Agricultural University, Hisar, during the Rabi seasons of 2022-23 and 2023-24, using the PSM-1 variety as the experimental material. The result showed that treatment T3 (RDF + Seaweed extract 2.5 ml/L) recorded highest plant height (103.22 cm), leaf area (370.63 cm²) and no. of branches per plant (11.63).
