“…Moreover, another factor that may have contributed to increases in WUE (Figure 4A) and iCE (Figure 4B) was the increase in potassium content in the plants due to the combination of manure with humic substances (Figure 2A). Potassium participates in cellular osmoprotection, enzyme activation, and positive regulation of photosynthesis (Shahid et al, 2023). The application of humic substances increased F v /F 0 , reaching the highest efficiency (3.78) when applying 8 kg ha -1 (Figure 4C), representing an increase of 23.53%.…”

Species of the genus Capsicum, especially peppers, are economically important and widely consumed worldwide. The application of animal waste as organic fertilizer is a simple and cost-effective technique for applying nutrients to the soil. Combining cattle manure with humic substances can stimulate plant metabolism, resulting in increased nutrient absorption and assimilation. Therefore, the objective in this study was to evaluate doses of cattle manure combined with humic substances for stimulating plant metabolism and morphophysiological and nutritional processes in pepper plants. A randomized block design with four replicates was used, in a 4×3 factorial arrangement consisting of four cattle manure doses (8, 18, 28, and 38 Mg ha-1) and three humic substance doses (0, 8, and 12 kg ha-1). Humic substances (12 kg ha-1) enhanced gas exchange, increasing net photosynthesis (34.2%), stomatal conductance (12.7%), instantaneous water use efficiency (15.87%), instantaneous carboxylation efficiency (37.37%), and absorbed energy conversion efficiency (23.53%). Cattle manure adequately met the crop’s nutritional requirements, while humic substances increased the number and thickness of plant root hairs. The most effective combination to increase photosynthetic activity in pepper plants was 38 Mg ha-1 of cattle manure combined with 8 kg ha-1 of humic substances. Humic substances stimulated positive morphophysiological responses in organic pepper crops, which resulted in increased production.
