Abstract

Two separate field experiments were conducted at the Experimental Farm of the Faculty of Agriculture, Menoufia University, during two successive seasons of 2020 and 2021. This investigation aimed to study the impact of seaweed extract and humic acid applications on the growth, flowering, and chemical constituents of Polyanthus tuberosa L. Plants were foliar sprayed with seaweed extract (SW) at 0, 0.5, 1, and 2 ml L-1, while humic acid (HA) was applied at 0, 0.2, 0.4, and 0.8 g L-1. The treatments were arranged as a factorial experiment in a randomized complete block design, and the obtained results were as follows:
