Optimizing Brussels Sprout (Brassica oleracea var. geminifera L.) Yield through Strategic Sowing Dates and Environmental Parameters across Various Growth Stages

Abstract

The important exotic vegetable crop in nutritive and cultivation concern had been planted on different dates to study the environmental effect on Brussels sprout growth and yield. The experiment was carried out during 2018 and 2019 at Punjab Agricultural University, Regional Research Station, Gurdaspur. The among cole crops brussels sprout is the leading source of protein (4.4) percentage by weight as well as total carbohydrate (8.9) percentage by weight and its also the richest source of calories (58) per hundred gram. (Brown and Hutchison 1949). The yield increases and positive response with maximum, minimum and mean temperature. The plant height also increases with the temperature. The positive and significant response of temperature with number of leaves, ten fruit weight and fruit diameter. The heat use efficiency had correlation with yield, plant height, number of leaves, ten fruit weight and fruit diameter gave positive and significant correlation. The maximum yield was recorded on 20 October planting date where as minimum was recorded in 10 November. The other character like plant height, number of leaves, ten fruit weight and fruit diameter also increase on early date of planting
