ENRIQUEZ DEL VALLE, José Raymundo et al. Fertigation in nursery plants of Agave potatorum Zucc micropropagated acclimatized. Rev. Mex. Cienc. Agríc [online]. 2016, vol.7, n.5, pp.1167-1177. ISSN 2007-0934.

The Agave potatorum Zucc, is a wild species collected in the field to produce a distilled beverage called mezcal, and not enough is known about their agronomic management and nutritional needs. The aim of the research was to evaluate breeding ground for five months in the development of micropropagated-acclimatized plants Agave potatorum Zucc which fertirrigaron with different amounts of nutrients. In the period 2013-2014, a total of 210 micro-propagated plants were established individually in pots of 300 cm3 with substrate was a 1:1 by volume perlite and peat were acclimatized for 60 days and 60 days greenhouse nursery. The acclimatized plants, uniform in size, split into six groups of 35 plants, to apply to each fertigation group with a different concentration (1, 20, 40, 60, 80 and 100%) of nutrients, universal solution Steiner. Daily on days 121-270 each plant is fertigate with 10 milliliters substrate level. At the end of the period, the data showed that the plants reached larger as they fertigation with increasing doses of nutrients, so plants fertigation 1 and 100% were 9.8 and 17 leaves, 126.53 and 392.35 cm2 of leaf area, 2.22 and 2.84 cm stem diameter, 10.5 and 17.4 taproots, 4 and 7.4 cm3 volume root, 2.79 and 6.50 g of leaf, dry weight, respectively.
