In order to investigate the effect of density and humic acid and seaweed extract on the quantitative and qualitative yield of sweet corn (Zea mays L.var. sacchrata) in Kohrang city an experiment was set up as factorial based on a completely randomized design with three replicates. In this experiment, the effects of potassium humic acid (use and non-use of potassium humic acid), seaweed extract (use and non-use of seaweed extract) and density (90,000, 100,000 and 110,000 plants per hectare) were evaluated. Phosphorus and soluble carbohydrate content of baby corn decreased with increasing density and increased with the application of humic acid and seaweed extract. The use of humic acid, seaweed and density caused a significant increase in dry weight of leaves, number of ears per unit area, yield of baby corn with husk, yield of baby corn without husk and biological yield. The density factor did not have a significant effect on the number of leaves per plant and the weight of baby corn without husk, but the use of seaweed and humic acid increased the mentioned traits compared to the control. The highest biological yield, yield of baby corn with husk and without husk was observed at 17264, 14730 and 5945 kg/ha respectively at a density of 110000 plants/ha. In general, the highest yield of baby corn (with and without husk) was observed at a density of 110000 plants per hectare with the use of seaweed and humic acid. |
