Organic seed production of leek (Allium porrum L.) in the Northeastern of Buenos Aires, 1: Yield components and quality

Abstract

The objective of this study was to characterize the organic seed production of leek for a representative site of thenortheastern of Buenos Aires. The Monstruoso de Carentán cultivar was studied in an Argiudol vertic soil, Ramalloseries. The seed to seed method was used. Green manure and earthworm compost were used as fertilizers. Phenology,climatic parameters, seed yield components and quality were evaluated. Phenological records showed that conditionswere appropriate for the seed to seed method. The leek vernalization requirements were met, and this contributed togood flowering (91%) and seed production. Seed yield was 78.4 g m-2 with 86% of seed germination (average of the2000/01 and 2001/02 cycles). The results of this study show that the agroecological conditions of northeastern of BuenosAires, can be considered as adequate for organic seed production of leek.
