Effect of plant density on the growth, development and yield of brussels sprouts (Brassica oleracea L. var. gemmifera L.)

Abstract

A b s t r a c tPlant density is an important variable for achieving maximum yields and uniform vegetable maturity. Optimal plant density can be achieved by establishing appropriate distances both between the rows as well as in the rows of plants. The experiment was carried out between 2010-2012 at the experimental field of the Crimean Agrotechnological University in Simferopol, Ukraine. The experiment was established as randomised blocks with four replications. This study aimed to determine the effect of plant density on the growth, development and yield of Brussels sprouts. Increasing the area per plant resulted in a shortening of the time to the beginning of head formation, technical maturity and harvest. In all study years, increasing the distance between plants caused an increase in leaf assimilation area, stalk diameter and the number of heads per plant, however, the height of plants was lower. The most favourable parameters characterising marketable yield were found at an area per plant of 0.56 m 2 , however, the maximum yield from 1 ha (determining the profitability of the cultivation) was found at an area of 0.49 m 2 per plant.

Production peculiarities of Brussels sprouts in Crime for conveyor delivery of its heads to the retail chain

“…Thus, Brussels sprouts growing of these two hybrids at the same time of planting plants in the open ground, may give you commercial products in 23 days. Products of early-ripening varieties of Brussels sprouts can be sold at the beginning of the first decade of October, late-ripening varieties -in the third decade of October [12].…”

Late cabbage planting density

“…Differentiation of plant density per unit area provides the ability to regulate the size of the edible plant parts. The optimal plant density can be achieved only by using an appropriate inter-row and intra-row spacing (Turbin et al, 2014), (Figure 3). Semuli (2005) indicated that reduced cabbage plant spacing causes increased competition for nutrients, light, air and moisture, which in turn may result in a reduced head diameter and weight.…”

“…No entanto, quando realizada com a quantidade ideal de sementes, além de otimizar os tratos culturais, proporciona acréscimo da produtividade (Turbin et al, 2014;Resende et al, 2015).…”
