abstract = {In this study, avocados of the Hass variety cultivated in Almuñécar (Granada, Spain) are
analyzed after soil mulching with pruning debris. The mulch treatment assay was composed of
pruning wastes from subtropical crops (avocado, cherimoya, and mango) and garden wastes from
the surrounding areas. The aim of this work is to analyze the nutrient content in avocado fruit and
the effect of pruning-waste mulching on fruit development over four years. Avocado fruits collected
in 2013, 2016, and 2017 were weighed, their volume and their sugar content were calculated, and
macro- and micronutrients were analyzed in the peel, pulp, and stone (endocarp and seed). The pulp
contained the highest concentration of nutrients, especially Cu, Zn, P, Na, and Ca. The peel presented
high concentrations of Mn, K, and N, while the stone recorded the lowest values in nutrients, with the
greatest decreases in years with the lowest precipitations registered. Over the study period, a decline
was detected in the nutrient concentrations related to the alternation of high and low yields, typical
of this crop, due to environmental factors. In the years 2016 and 2017, avocados accumulated higher
amounts of micronutrients and P, presumably because of greater water availability in the soil. During
the study period, the application of pruning wastes did not affect the nutrient concentration of fruits
except for the garden pruning waste in certain elements in the pulp during the last study year.},
