MOISTURE LOSS DYNAMICS IN HAZELNUTS UNDER SUN AND SHADE CONDITIONS

The purpose of the research -The research aimed to investigate the dynamics of moisture loss in hazelnuts under different drying conditions.The goal was to compare the effectiveness of sun and shade drying and to analyze how different genotypes, including the local 'Ata-baba' cultivar, respond to these treatments.The methodology of the research -Hazelnut samples ('Ata-baba' and two genotypes) were collected from orchards in Lekit village, Gakh district of Azerbaijan.Drying treatments were arranged so that genotype 1 was dried only in shade, genotype 2 only in sunlight, and 'Ata-baba' under both conditions.Nuts were weighed individually twice daily until a constant weight was achieved, and percentage moisture loss was calculated.The practical importance of the research -The study provides practical recommendations for hazelnut producers to choose effective drying methods that minimize biochemical deterioration and preserve kernel quality.The results of the research -Sun drying was significantly more effective, with nuts reaching constant weight within 5-6 days, while shade drying required longer.Total moisture reduction ranged from 19.33% in genotype 1 (shade) to 27.94% in 'Ata-baba' (sun).Initial drying rates were also higher under sun conditions, highlighting both environmental and genetic influences.The scientific novelty of research -This is the first comparative study in Azerbaijan that systematically evaluates the combined effect of drying conditions and genotype on hazelnut moisture loss.
