Effect of Organic and Inorganic Fertilizers on the Yield and Quality of Jalape？o Pepper Fruit (Capsicum annuum L.)

Organic fertilizers were evaluated on jalapeno pepper ( Capsicum annuum L.) and on their effect on the soil content of nitrogen (N), phosphorus (P), electrical conductivity (EC), pH and organic matter (OM), at the Experimental Station of the Agriculture and Zootechnics Faculty (FAZ-UJED), Ejido Venecia, Durango, México. The assayed experimental fertilizers were vermicompost (VC) with 0 and 3 Mg ha ？1, in factorial combination with solarized manure (SM), with 0, 40, 80, and 120 Mg ha ？1, and an inorganic fertilization nitrogen-phosphorus-potassium (NPK) at 150–100–00 Mg ha ？1. Microbiological analyses were performed to evaluate the presence of Salmonella spp. The highest yield was 56.2 Mg ha ？1 with 120 Mg ha ？1 SM, which was statistically similar to 40 and 80 Mg ha ？1; the highest P content (70.7 mg kg ？1) and OM (3.7%) occurred with 120 Mg ha ？1 SM. The inorganic fertilizer reflected the lowest OM (1.1%). Nutrients provided by SM were sufficient to satisfy the crop needs. Values of pH, EC and N were not affected by SM. The fruit quality was not affected by the organic fertilizers. Most fruits were classified as Second-Class Quality (60%), followed by First-Class Quality (25%). Microbiological analyses were negative for Salmonella spp., suggesting that the SM is effective in its elimination. View Full-Tex
