Effects of Root and Foliar Application of Corn Steep Liquor on Pepper Plants: A Physiological, Nutritional, and Morphological Study

The industrial washing of corn grain during its milling generates a residue known as “corn steep liquor (CSL)”. This is rich in amino acids, carbohydrates, vitamins, and mineral nutrients that can stimulate the vegetative growth when applied to plants. However, mode action this product not yet known. work involved foliar root application pepper plants, at dose 5 mL L−1, two CSL products (CSL-H CSL-B), which differ way they have been stabilized. In both cases, size plants was increased, being more efficient than foliar. According studies carried out, because increased synthesis hormones related cell division elongation, net assimilation rate CO2, concentrations acids alanine, proline, tryptophan. addition, CSL-H also arginine, isoleucine, leucine, cysteine. These data suggest these regulation, hormones, stimulation carbon nitrogen metabolism, treatment one produced most changes analyzed.
