Intercropping systems of cowpea with radish are beginning to be deployed in the semiarid region of Rio Grande do Norte state. The great challenge is to know whether or not there is productive efficiency in these systems when fertilized with organic matter produced by spontaneous species from the ‘Caatinga’ biome. Thus, the aim of this study was to evaluate the productive performance of cowpea-radish intercropping systems under different amounts of rooster tree biomass incorporated into the soil. The study was conducted at the experimental farm Rafael Fernandes, rural zone of Mossoró, RN, in the period from June to September 2013, in an experimental design of randomized blocks with four treatments and five replicates. The treatments consisted of the following amounts of rooster tree biomass incorporated into the soil (10, 25, 40 and 55 t ha-1 on a dry weight basis). The best productive performance of the cowpea-radish intercrop was obtained when the rooster tree biomass amount of 50.01 t ha-1 was incorporated to the soil. The use of rooster tree biomass as green manure is agronomically viable in intercropped systems of cowpea-radish.

The use of green manures in vegetable crop production systems has increased, but there is still a lack of information about the correct handling of the species for better use by culture. Two field experiments were conducted in Serra Talhada in the semiarid of Pernambuco state, Brazil, to evaluate the effects of amounts of biomass and times of Calotropis procera incorporation into the soil in the agronomic performance of the beetroot 'Early Wonder' in two growing seasons (fall and spring-summer). The experimental design was a randomized block in three replications. The treatments were arranged in a 4 x 4 factorial scheme, with the first factor corresponding to the quantities of C. procera biomass (5.4, 8.8, 12.2, and 15.6 Mg ha -1 on a dry basis) and the second to the times of incorporation into the soil (0, 10, 20, and 30 days before sowing of beetroot). The following characteristics were assessed in the beetroot: plant height, number of leaves per plant, root diameter, total productivity, commercial productivity, and dry mass of roots. The amount of C. procera as well as the time of incorporation and growing season directly influenced the agronomic performance of beetroot. Regardless of the assessed agronomic characteristics, increasing amounts, and decreasing the time of incorporation proportionally influenced the performance of beetroot. The best agronomic performance of the beetroot was obtained by fertilization with 15.6 Mg ha -1 of C. procera. The ideal time of incorporation of green manure coincided with the date of the sowing of beetroot. The cultivation in the fall season resulted in higher total and commercial productivity of beetroots fertilized with C. procera.

-The production of vegetable crops is characterized by intensive land use, high input demands and the requirement of strategic management adoption with an agro-ecological approach. In this study, agronomic indicators were evaluated in lettuce fertilized with different amounts of roostertree biomass; fertilizer was incorporated into the soil at distinct times and seedlings were planted in two cropping seasons (spring and autumn-winter) in Serra Talhada, Pernambuco state, Brazil. The experimental design consisted of randomized complete blocks with three replications and treatments arranged in a 4 x 4 factorial scheme. The first factor was the amounts of roostertree biomass (5.4, 8.8, 12.2, and 15.6 t ha -1 on a dry basis) and the second the manure incorporation times (0, 10, 20, and 30 days before lettuce transplanting). The variables evaluated in the lettuce crop were: plant height and diameter, number of leaves per plant, productivity of green mass, and dry shoot mass. Maximum productivity and dry shoot mass were obtained using fertilization with 15.6 t ha -1 . A synchrony between supply of nutrients by green manure and the period of maximum demand by lettuce was observed in the incorporation times of 10 (spring) and 20 (autumn-winter) days before transplanting. Cultivation in the spring resulted in higher vegetative growth.Keywords: Lactuca sativa L.. Roostertree. Organic cropping. PRODUÇÃO DE ALFACE SOB ADUBAÇÃO VERDE COM Calotropis procera EM DUAS ÉPOCAS DE CULTIVORESUMO -A produção de hortaliças é caracterizada pelo uso intensivo da terra, pela alta demanda de insumos e pela necessidade de gestão estratégica com uma abordagem agroecológica para sustentar a produção. Indicadores agronômicos foram avaliados em alface adubada com diferentes quantidades de biomassa de Florde-seda, em diferentes épocas de incorporação ao solo e plantadas em duas estações de cultivo (primavera e outono-inverno) em Serra Talhada, Pernambuco, Brazil. O delineamento experimental consistiu em blocos ao acaso com três repetições e os tratamentos arranjados em esquema fatorial 4 x 4. O primeiro fator foi à quantidade de biomassa de 4; 8,8; 12,2 e 15,6 t ha -1 em base seca) eo segundo os tempos de incorporação do adubo (0, 10, 20 e 30 dias antes do transplante da alface). As características avaliadas na cultura da alface foram: diâmetro de plantas, número de folhas por planta, altura de plantas, produtividade de massa verde e massa seca da parte aérea. As produtividades máximas de massa verde e seca foram obtidas na quantidade de biomassa de Flor-de-seda de 15,6 t ha -1 incorporada no solo. Observou-se uma sincronia entre a oferta de nutrientes pelo adubo verde e o período de máxima demanda pela alface nos tempos de incorporação de 10 (primavera) e 20 dias (outono-inverno) antes do transplantio. O cultivo na primavera resultou em maior crescimento vegetativo para a cultura. Palavras-chave:Lactuca sativa L.. Flor-de-seda. Cultivo orgânico.
