MEXICAN LIME RESPONSE TO TWO TYPES OF FERTILIZATION IN A CONTAINER PRODUCTION SYSTEM

Abstract

Objective: to evaluate the response of the growth of the aerial part and root in two varieties of Mexican lemon [Citrus aurantifolia (Christm) Swingle] using two types of fertilization, in a container production system.

Design/methodology/approach: the work was established on the grounds of the Tecomán Experimental Field of INIFAP in 2018, using the varieties of Mexican lime `Lise? and` Colimex? established in polypropylene containers. The substrate was loamy sandy soil with coconut powder and two types of fertilization were added: fertilization one, 2-1-1 ratio of nitrogen, phosphorus and potassium respectively and fertilization two, based on the extraction of nutrients from the fruit. Seven months after the transplant, response variables were recorded: stem diameter of the rootstock (DTP), full height of the plant (ACP), equatorial diameter of the crown (DEC) and root volume (VR). Mean comparisons were made between the management factors used (variety-fertilization) and their interactions with the response variables, using a completely randomized experimental design with 15 replicates per treatment.

Results: growth variables (DTP, ACP, DEC and VR) of Mexican lime `Lise? and` Colimex? in juvenile stage obtained the best response using fertilization based on the extraction of nutrients from the fruit. The ?Lise? variety generated higher ACP and `Colimex? developed greater growth in the rest of the response variables analyzed.

Limitations of the study/implications: Continue with the evaluation to determine the effect of the factors on the production and quality of the fruit.

Findings/conclusions: the varieties of Mexican lime ?Lise? and ?Colimex? showed good growth in containers. Fertilization based on the extraction of nutrients from the fruit exceeded the 2-1-1 ratio of nitrogen, phosphorus and potassium respectively.
