| Abstract: The objective of this work was to determine the nitrogen rate for fertigation associated with the maximum productivity of green corn (Zea mays) with a lower production cost, in two harvest seasons in the Brazilian semiarid region. The experimental design was a randomized complete block with four replicates, and the treatments consisted of four N rates (0, 80, 160, and 240 kg ha-1) in form of urea, applied via drip irrigation. The used cultivar was the Bt Feroz hybrid. The evaluated characteristics were: number and mass of marketable ears, gross income, net income, and rate of return. The greatest amounts of marketable ears were reached with 152.52 kg ha-1 N in summer (41,183.84 ears per hectare) and 190.31 kg ha-1 N in winter (53,291.25 ears per... |

| RESUMO Indicadores agronômicos foram avaliados no rabanete adubado com diferentes quantidades de biomassa de Calotropis procera (Ait.) R. Br. (Flor-de-seda), em distintos tempos de incorporação ao solo e cultivada em duas épocas (primavera e outono-inverno), no município de Serra Talhada-PE. O delineamento experimental foi em blocos casualizados, com os tratamentos arranjados em esquema fatorial 4 x 4, com três repetições, sendo o primeiro fator: as quantidades de biomassa de C. procera (5,4; 8,8; 12,2 e 15,6 t ha-1 em base seca); e o segundo: tempos de incorporação ao solo (0; 10; 20 e 30 dias antes do plantio do rabanete). As características determinadas no rabanete foram: altura de plantas, número de folhas por planta, diâmetro de raízes, massas seca e... |

| ABSTRACT The present study was carried out to determine the amount of biomass of Calotropis procera and itsincorporation time into the soil that provide maximum productivity and profitability in the organic cultivation of coriander during the spring and autumn-winter, under the conditions of Serra Talhada, in the state of Pernambuco, Brazil. The experiment was conducted in a randomised complete block design, in a 4 x 4 factorial scheme with three replications. The first factor corresponded to the amount of biomass (5.4, 8.8, 12.2 and 15.6 t ha-1 on a dry basis), and the second to the incorporation time (0, 10, 20 and 30 days prior toplanting the coriander). In addition to the green-matter yield and production costs, the following economic indicators were... |

| ABSTRACT The use of spontaneous species of the Caatinga biome can contribute significantly to the nutritional demand of vegetable crops, thereby providing an agroecological and sustainable form of production. The objective of this research was to determine the effects of different biomasses of Calotropis procera (rooster tree) and times of incorporation into the soil of green manure during two growing seasons on the agronomic performance of coriander cv. Verdão produced in Serra Talhada, a semi-arid region of Pernambuco, Brazil. The experimental design was randomized blocks with three replications. The treatments were arranged in a 4 x 4 factorial scheme, with the first factor consisting of biomass amounts of C. procera (5.4, 8.8, 12.2 and 15.6 t ha-1 on a... |
