Abstract

A research study was conducted to determine the effects of different dozes of humic acid on growth and yield of marigold at Horticulture Nursery University of Haripur, Khyber Pakhtunkhwa, during spring season. The experiment was laid under Completely Randomized Design with 05 replications and 08 pots pre replications were used. The treatments of humic acids were (T1= control, T2= 250, T3= 750, T4= 1000 ml/L respectively). Significant differences were found in treated flowers. The higher values were noted in leaf length, number of flowers plants, flower width, and flower length. The higher values of leaf length (7.4 cm), number of flowers plant (2.9), flowers width (9.92 cm) and flowers length (20.18 cm) were found by the application of 750 mg of humic acid. However the maximum number of flowers per plant was (5), flower width (1.48 cm) and flower length (3.28 cm) were found with the application of 1000 mg humic acid.

Highlights

Calendula (Calendula officinalis L.) is one of the major ornamental and medicinal plant it known as pot marigold
The similar results were reported by [10] concluded that the humic acid in 250 ml L-1 concentrations, increased the number of marigold leaves which could be due to positive mineral effects and the hormonal activity of humic acid on vegetative growth
The observation revealed that the application of humic acid at different doses had a significant effect on the leaf length of calendula flower (Table 1)

Summary

Introduction

Calendula (Calendula officinalis L.) is one of the major ornamental and medicinal plant it known as pot marigold. It is used in wound healing and as antiseptic. Humic acid is a commercial product containing abundant nutrients improves soil fertility and increase the availability of nutrients to plants and it influences plant growth and yield [6].

Keeping in mind the importance of humic acid the present study was launched to evaluate the influence of different doses of Humic acid on growth, yield and flowering of (Calendula officinalis)
