A STUDY ON SCALLION YIELD AND QUALITY IN ONION GENOTYPES ACCORDING TO HARVEST TIME

Abstract

Green onion quality varies by genotype, ecology, harvesting period and production material. In the study performed as a greenhouse test, the pots were filled with peat:perlite mixtures (3:1 v/v) and 140 sets per m(2) were planted in the pots on 21st of October. The green onions were harvested in three periods (on 30th, 60th and 90th days) following planting of sets. Yield (kg/da), plant height (cm), white stalks length (cm), pyruvate content (mu m/m1), and soluble solids content (g/100 g) were determined in the harvested plants. Yield values varied between 1072.33 and 3880.67 kg/da depending on genotypes. BayramIt and Osmanbey genotypes yielded the highest yield values in second and third harvesting respectively. The following genotype heights were found out to be superior: Yayladalt and Osmanbey in terms of white stalks length, BayramIt and Osmanbey in terms of low pyruvate content and Calkoy, Karaca-1 and Bayramlt in terms of soluble solids content. Use of productive and quality specialties obtained as per consumption purposes of green onion is significant in terms of agricultural production and sustainability.
