The effect of planting times on some vegetable characters and yield components in Brussels sprouts (Brassica oleracea var. gemmifera)

Abstract

This study was carried out to determination of two planting times (July and August) on some vegetable characters as first sprout initiation time, sprout number, weight and size, the time from first sprout initiation to harvest, plant weight and height, fresh and dried weight of leaf, stem and root, stem diameter and yield components on Brussels sprouts (Brassica oleracea var. gemmifera cv. De La Halle) in terms of their response to temperature. +5°C was considered as critical temperature (base temperature) to calculate thermal time. Total yield per plant was found 307.9 and 308.5 g plant-1 for first and second planting times, respectively. Thermal time needed from planting to bud initiation was 1100-1300°C day-1, thermal time needed from bud initiation to harvest was 390-460°C day-1. The time from planting to bud initiation and from bud initiation to harvest were measured 119 day and 67 day in First Planting Ttime (FPT) and 105 day and 74 day in Second Planting Time (SPT), respectively. © 2006 Asian Network for Scientific Information.
