The chemical quality of almonds variety Guara cultivated in nonirrigated farming (NI) and drip-irrigated farming (DI) conditions with different fertilizing treatments, two organic treatments (T1 and T2) and a mineral treatment (C), all of them with a N-P-K proportion of 1-2-1, is studied. Almonds obtained in irrigated farming showed higher content in sugars and organic acids and a better quality of oil. Among the fertilizing treatments employed, the organic ones have shown the best results related to chemical quality, regardless of the quantity of fertilizer employed (9.5 kg per T1 tree vs 4.5 kg per T2 tree). The organic treatments produced almonds with a higher content of sugar, organic acids and fiber and a similar fat content. These results are interesting from a commercial point of view since the consumers, even under the same conditions of chemical quality, prefer those products cultivated under organic conditions due to their benefits for health and because these practices are environment-friendly.
