Resumen

ZUNIGA-ESTRADA, Lamberto; ROSALES ROBLES, Enrique; YANEZ-MORALES, María de Jesús  y  JACQUES-HERNANDEZ, Cuauhtémoc. Characteristics and productivity of a MAC plant, Agave tequilana developed with fertigation in Tamaulipas, Mexico. Rev. Mex. Cienc. Agríc [online]. 2018, vol.9, n.3, pp.553-564. ISSN 2007-0934.  https://doi.org/10.29312/remexca.v9i3.1214.

In the cultivation of Agave tequilana, the studies have been restricted to a part of its long cycle and to short periods of time, for this reason, with the objective of evaluating the agronomic characteristics in plant and pineapple in a complete cycle of the plant, they established suckers from Jalisco in the south of Tamaulipas in three conditions: a) in temporary and without fertilizer (TA); b) fertigation, in addition to precipitation, received water and nutrients (N, P, K, Ca, Mg, and micronutrients) through a drip irrigation system; and c) FB+fertigation, in addition to the above, these plants received basic fertilization (FB), with N, P, K and micronutrients, each treatment had three repetitions. Eight destructive evaluations were carried out using one plant per experimental unit, September 2004, February 2005, October 2005, 2006, 2007, 2008, 2009 and 2010. The plants developed with fertigation and fb+fertigation, on average exceeded 26% and 57% the height and number of leaves of plants of the TA, respectively; the highest annual production of dry matter (MS) was 51.8 t ha-1, estimating a total biomass per plant of 491.4 and 456.1 t ha-1 and 218.1 and 252.4 t ha-1 in the pineapple, respectively. In TA plants the total biomass was 97 t ha-1 and a pineapple yield of 46.5 t ha-1. In pineapple the sugars evaluated in ºBrix and total reducing sugars (ART) were not affected by the treatments. The concentration of ART in the pineapple fluctuated between 26.8 and 29%. The concentration of glucose and fructose was similar in early stages of pineapple development; however, at the end of the cycle during the maximum growth stage the mean value in the fructose concentration was 246.8 g per kg MS of pineapple and represented 88% of the two soluble monosaccharides evaluated, the glucose presented an inverse behavior and represented the remaining 12%.
