Abstract

Baby leaf consumption in Brazil has potential to increase significantly. It is an attractive crop due to its small size, texture and flavor, which may stimulate larger vegetable consumption. Market and production systems are starting to establish in Brazil. Thus, they need to be studied in order to gain knowledge of how to produce baby leaf in each production system. The choice of the correct fertilizer management is essential for a conscious production of baby leaf that aims at high yield, cost reduction, product quality and environment preservation. Among the nutrients, nitrogen is of crucial importance to the morpho-physiological changes occurring in vegetables. Moreover, the aim of this study was to evaluate the development of lettuce (Lactuca sativa L. 'Elisa') and table beet (Beta vulgaris L. 'Tall Top Wonder') at different nitrogen doses. So that could be done, two independent experiments ( January 16 to February 29 of 2012) were carried out at the Agronomic Institute (IAC), in Campinas, Sao Paulo, Brazil. The experimental design for both essays was randomized blocks with four replicates. The main treatment consisted of five nitrogen doses (0.16, 0.32, 0.64, 1.28 and 2.56 g L-1), applied thought fertilization. The harvest was carried out when the leaves of each species reached length of approximate 15 cm. The main treatment consisted of five nitrogen doses (0.16, 0.32, 0.64, 1.28 and 2.56 g L-1). For baby leaf production, 1.5 g L-1 of nitrogen for lettuce and 1.8 g L-1 for table beet were the doses that provided the highest yield. (AU)
