“…Com esta prática, busca-se maior produção por área pela combinação de plantas que irão utilizar espaço, nutrientes e luz solar, além dos benefícios que uma planta traz para a outra no controle de plantas concorrentes, pragas e doenças (PIVETTA, et al, 2007;SILVA et al, 2011). Entre as espécies olerícolas que se pode combinar com vantagens agroeconômicas e ambientais estão a alface e rúcula (COSTA et al, 2007;OLIVEIRA et al, 2010). Elas têm elevado valor nutricional, são bastante usadas na alimentação humana e contribuem primariamente com vitaminas e sais minerais.…”

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.

“…Abreu et al (2010), Oliveira et al (2010), and Resende et al (2010) observed that the production of lettuce, lettuce, and rocket and onion, respectively, was improved using the organic system. In contrast, Carvalho et al (2013), Menezes Júnior et al (2014, and Santos et al (2015) observed that the conventional system was superior to the organic system regarding the increase in carrot, onion, and green corn production, respectively.…”

Production systems influence crops differently, mainly in terms of yield. However, there are few studies that have evaluated different bushing snap bean genotypes in different systems. Thus, this study aimed to evaluate the production components and yield of bushing snap beans in conventional and organic production systems. The experimental design was a randomized complete block, in a factorial 6 × 2 arrangement, corresponding to six genotypes and two production systems, with three replications. The genotypes Isla Manteiga Baixo ®

“…Bulb diameter according to the types of fertilization: control -A0, earthworm humus -A1, earthworm humus + NPK -A2 (5A) and nitrogen doses: 0, 0.7, 1.4, 2.1 and 2.8 g pot -1 (5B) of the beet at 45 days after transplanting Bulb fresh weight and bulb dry weight as a function of the basal fertilization showed better performance in the fertilizations with earthworm humus and earthworm humus + NPK, compared with the control, which contained only the nutrients present in the soil analysis ( Figures 6A and 6B). Oliveira et al (2010) report in their studies that organic fertilization and associated with mineral fertilization positively influence the yield of the crops, since the nutrients are not easily lost by leaching or volatilization. Damasceno et al (2011), studying beet yield as a function of N doses, observed that as the N dose increased there was an increment in bulb fresh phytomass.…”

Chemical fertilizers have been increasingly used in agriculture. The application of these nutrients via irrigation water has been evaluated in order to obtain productive results in agricultural yield. The objective of this research was to evaluate the effect of nitrogen (N) doses, applied by fertigation and associated with different types of basal fertilization, on the growth and production of beet. The experiment was conducted at the Federal University of Campina Grande (UFCG), in a protected environment belonging to the Academic Unit of Agricultural Engineering (UAEA). The adopted statistical design was completely randomized blocks, with three replicates, and the factors were arranged in a 5 × 3 factorial scheme, corresponding to five N doses (0, 50, 100, 150 and 200 mg dm -3 of soil), and three types basal fertilization (soil without fertilizer, earthworm humus, earthworm humus + NPK). At 45 days after transplanting, the number of leaves per plant, plant height, stem diameter, leaf area, green intensity, bulb diameter, stem length, bulb fresh weight, bulb dry weight and total soluble solids (°Brix) were quantified. Both Soil basal fertilization significantly influenced beet growth and production, and the treatment with earthworm humus and earthworm humus + NPK led to the best results for the analyzed variables. The highest N dose promoted the best performance for stem diameter and content of total soluble solids (°Brix).
