| ABSTRACT The objective of this research was to evaluate the agronomic performance of Italian zucchini as a function of phosphate fertilization. The experiments were carried at the Rafael Fernandes Experimental Farm, Federal Rural University of the Semi-Arid Region, Mossoró, RN, Brazil, from August to November 2015 and from July to September 2016. The experimental design was randomized blocks in 2 x 5 factorial scheme, with four replicates. The treatments consisted of the combination of two cultivars (Caserta and Alícia) and five doses of phosphorus (0, 40, 78, 120 and 150 kg ha-1 of P2O5). Phosphorus doses associated with the maximum marketable yields estimated were smaller for Alícia than for Caserta in the period from August to November 2015. In the... |

| ABSTRACT Nitrogen exerts a marked influence on the yield and quality of the onion. The present work was developed from June to October 2016, aiming to evaluate the yield and quality of two cultivars of onion under a system densified as a function of nitrogen doses in Mossoró, RN, Brazil. A randomized block design was used in a 2 x 7 factorial scheme, with four repetitions, corresponding to two cultivars (IPA 11 and Rio das Antas) and seven nitrogen doses (0, 45, 90, 135, 180, 225 and 270 kg ha-1 of N), provided by fertigation, with four repetitions. The dose of 92 kg ha-1 of N provides the highest total and marketable yields of bulbs. Nitrogen fertilization increases the concentrations of N, chlorophyll a, b and total in the leaves of the onion, as well as... |
