Resumo -O presente trabalho teve como objetivo avaliar o desempenho agronômico do consórcio de alface e rúcula fertilizado com diferentes quantidades de biomassa de flor-de-seda incorporadas ao solo. O experimento foi conduzido no período de setembro a novembro de 2011, na área de pesquisa da Fazenda Experimental Rafael Fernandes da Universidade Federal Rural do Semi-Árido, Mossoró-RN. O delineamento experimental utilizado foi em blocos ao acaso com cinco tratamentos e quatro repetições. Os tratamentos consistiram das seguintes quantidades de biomassa de flor-de-seda incorporadas ao solo (5,15, 25, 35 e 45 t ha -1 em base seca). As características avaliadas nas hortaliças foram: altura e diâmetro de plantas (alface), número de folhas por planta, produtividade (alface), rendimento de massa verde (rúcula) e massa seca da parte aérea. A eficiência do cultivo consorciado foi determinada pelo escore da variável canônica. A otimização do desempenho agronômico da alface consorciada com rúcula foi viabilizada com a incorporação de aproximadamente 37 t ha -1 de flor-deseda ao solo. O uso de flor-de-seda como adubo verde é viável agronomicamente no cultivo associado de alface e rúcula, além de contribuir para um melhor aproveitamento dos recursos ambientais.Palavras-chave: Adubação verde.

AGRONOMIC EFFICIENCY OF THE INTERCROPPING LETTUCE-ARUGULA FERTILIZED WITH ROOSTERTREEAbstract -The present work aimed to evaluate the agronomic performance of lettuce-arugula intercropping fertilized with different amounts of roostertree biomass incorporated into the ground. The experiment was conducted during the period of September to November of 2011, in the research area of the Experimental Farm Rafael Fernandes, Universidade Federal Rural do Semi-Árido, Mossoró-RN. The experimental design used was randomized blocks with five treatments and four replications. The treatments consisted of the following biomass amounts of roostertree incorporated into the soil (5, 15, 25, 35, and 45 t ha -1 on a dry basis). The characteristics evaluated in the vegetables were: height and diameter of plants (lettuce), number of leaves per plant, productivity (lettuce), yield of green mass (arugula) and dry mass of shoots. The efficiency of intercropping system was determined through the score of the canonical variable. The optimization of the agronomic performance of the lettuce intercropped with arugula was made possible with the incorporation of about 37 t ha -1 of roostertree into the ground. The use of roostertree as green manure is agronomically viable in the intercropping of lettuce and arugula besides contributing to a better use of environmental resources.

“…The narrow C:N ratio situated in the range between 20 to 30:1 of the roostertree in the edaphoclimatic conditions of the semiarid region of Pernambuco allowed a rapid mineralization and release of nutrients (GÓES et al, 2011;ALMEIDA et al, 2015). Snyder et al (2009) found that shoot mass, total and commercial productivity of carrots enhanced with increases in N availability, but they highlighted that the mineralization of other nutrients from plant biomass are essential to increase productivity.…”

ABSTRACT:Because vegetables have a fast production cycle, they require fertilization in quantities and at ideal times to obtain maximum productivity, and green manure is an alternative practice to the use of mineral fertilizers. This study was conducted to evaluate the effects of different amounts of roostertree [Calotropis procera (Ait.) R. Br.] biomass and its incorporation times in two growing seasons, in the agronomic performance of carrots. The experiment was conducted on an experimental farm at the Universidade Federal Rural de Pernambuco (UFRPE) in the autumn-winter period (March-July 2012) and the spring-summer period (September-December 2012). The experimental design was a randomized block design with three replications. The treatments were arranged in a factorial 4 x 4 design; the first factor consists of four amounts of roostertree biomass (5.4, 8.8, 12.2 and 15.6 t ha -1 on a dry basis), and the second factor consists of four times of incorporation of this manure into the soil (0, 10, 20 and 30 days before sowing the carrots). The carrot cultivar used was Brasília. The following traits were evaluated: plant height, number of leaves per plant, root dry mass, total and commercial yield of roots. The best agronomic performance of carrot cultivar Brasília was found with the amount of roostertree biomass of 15.6 t ha -1 , in the time of incorporation into the soil of 10 days before seeding. The cultivation in the autumn-winter showed higher total and commercial productivities of carrot roots fertilized with roostertree.

“…These positive results are due probably to the greater availability of macro and micronutrients, which were released to the soil via roostertree manure, promoting soil fertility (BATISTA et al, 2013;GÓES et al, 2011). Fertilization with plant species that occur spontaneously in the region also favors microbiological soil aspects, with an increase in the number of fungi, actinomycetes, and other bacteria beneficial for plant growth (BATISTA et al, 2013).…”

“…The author found that using roostertree manure resulted in better plant development than using oneleaf senna (S. uniflora) as manure. Using the same location and growing seasons, Góes et al (2011) ) with incorporation of 6.68 t ha -1 of hairy woodrose 30 days before lettuce transplanting. These values were much lower than those found in our study, probably due to the high average air temperature (above 28°C) in both cultivation periods.…”

-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.
