Growth and nutrition in plants

Vegetable development and productivity are influenced by several factors, including the nutrient amounts available. Providing adequate nitrogen favours vegetative growth and promotes increased productivity, in addition to providing greater succulence and improving leaf quality. This work evaluated the effect of nitrogen doses and sources on arugula culture development and productivity. The experiment was conducted on the experimental farm at the State University of Goiás, Ipameri campus, in the municipality of Ipameri, Goiás state (GO). The experiment used a 2 × 5 factorial randomized complete block design, with two sources (normal urea and coated urea), five nitrogen doses (0, 60, 120, 180 and 240 kg ha-1 of N) and four replicates. Plant height, stem diameter, leaf number, fresh shoot matter, dry shoot matter and productivity were evaluated. The results obtained here suggest that nitrogen sources do not influence arugula culture development, but nitrogen doses influence the arugula culture’s productive characteristics.
