Abstract
The results showed that the interaction effects of pumice and the simultaneous foliar spraying with seaweed extract and Hoagland's solution caused a 97% increase in pod length and 112% in width, a 73% increase in plant dry weight, a 39% increase in seed number per plant and 55% increase in seed yield compared to the control plant. The plant height increased under 60 tons.ha-1 of pumice application alone and in combination with foliar spraying with both fertilizers. Foliar spraying with Hoagland's solution, along with simultaneous foliar spraying of both compounds (seaweed extract + Hoagland's solution) with pumice application enhanced the number of nodes, sub-branches, and the weight of 100 seeds of the plant. Pumice application (zero and 60 tons.ha-1) along with the spraying alone and simultaneous spraying of both fertilizers, increased the nitrogen content of the plants. Potassium content was increased when 60 tons.ha-1 of pumice + simultaneous foliar spraying of both compounds and algae extract spraying was applied. The effect of pumice application (60 tons.ha-1) influenced the pod number per plant, as well as the flavonoids and phenolics, calcium, magnesium, and manganese content of the plant. The co-application of seaweed extract + Hoagland's solution raised the protein (40%) and oil (21%) percentages of the seeds. There was a positive correlation between seed yield, elements content, oil percentage, root dry weight, and biological yield, and this shows that a balanced nutrition with nutrients is necessary to reach reliable yield components.
