Production of chile de árbol (Capsicum annuum L.) seedling with designation of origin in Yahualica, Jalisco

Abstract

Objective: Different chile de árbol (Capsicum annuum L.) seedling production systems were evaluated and compared with traditional systems to identify the effects of new techniques.

Design/Methodology/Approach: Five chili varieties from different regions were evaluated (S1O, S2B, S3L, S4J, and S5A). The methods used in the experiment were greenhouse germination trays (GT) and open field nurseries (OFN). In addition, traditional (T), conventional (C), and alternative (A) fertilization systems were used. The variables evaluated were plant height (PH), stem diameter (SD), and number of leaves (NL).

Results: The GT + A fertilization treatment increased the PH and NL of the seedlings. The OFN + T combination stood out during the last stages, recording a higher PH. Meanwhile, the GT + C seedlings achieved a regular growth, obtaining good ST and NL results during the intermediate stages. At 30 and 45 days, S2B + GT + T recorded the highest PH and NL, while, at 60 days, S2B + GT + A obtained the highest SD and PH. At 90 days, S2B + OFN + T recorded the highest PH.

Study Limitations/Implications: The seedling production of the open field nurseries was 15 days behind the 60-day greenhouse germination tray system (GT) with peat moss.

Findings/Conclusions: The traditional method recorded the most homogenous plants. The OFN + A treatment and the OFN + T treatment had good performance and adaptability. The root analysis showed that the A system promoted a better root development. Management systems did not impact the health quality of the crops.
