“…These data were contrary to those reported by Almeida et al (2015) who observed higher productivity of lettuce and arugula when green manure was applied. The greatest number of roses of control shows that the intercropping with green manures was not favorable for the development of plants, as may have been competition between rosebushes and legumes.…”

Rose cultivation requires many inputs for satisfactory production, making the process expensive. Nowadays, alternative practices have been used for sustainable crop production. Green manure is an agricultural practice that aims to maintain or improve soil fertility, increasing its yielding capacity. The objective of this research was to evaluate the effect of green manure with legumes on the yield and quality of 'Vegas' roses. Grafted rose seedlings were cultivated in open field for 30 months. Legumes used as green manure and planted intercropped with rose bushes were forage peanut (Arachis pintoi) and jack bean (Canavalia ensiformis). Pigeon pea (Cajanus cajan) was grown in a separate area, cut, macerated, and applied in the rows between rose bushes every 3 months. Plants of control group received no green manure, only mineral fertilizer and cattle manure, as in all other treatments. The experimental design was randomized block with four treatments (three green manure species plus the control) and seven replications. The highest yield and quality of flower stems in 'Vegas' occurred with addition of pigeon pea on the soil surface or chemically treated (control). Forage peanut and jack bean are not suitable for intercropping with 'Vegas' rose bushes due to possible nutrient and water competition. Keywords: floriculture, legumes, organic fertilization, sustainable production. RESUMO Adubação verde influencia produção e qualidade de flores de corte da roseira 'Vegas'A cultura da roseira demanda a aplicação de diversos insumos agrícolas para uma produção satisfatória, o que torna o processo oneroso. Atualmente, tem-se buscado o uso de manejos alternativos para um cultivo vegetal sustentável. A adubação verde é uma prática agrícola que visa conservar ou melhorar a fertilidade do solo, aumentando sua capacidade produtiva. O objetivo dessa pesquisa foi avaliar o efeito da adubação verde com leguminosas na produção e qualidade de rosas cultivar 'Vegas'. Mudas enxertadas de rosas foram cultivadas a céu aberto durante 30 meses. As leguminosas utilizadas como adubo verde e plantadas em consórcio com as roseiras foram o amendoim forrageiro (Arachis pintoi) e feijão de porco (Canavalia ensiformis). O feijão guandu (Cajanus cajan) foi cultivado em área separada, cortado, triturado e aplicado a cada três meses na superfície do solo na linha de plantio da roseira. As plantas do grupo controle não receberam nenhuma adubação verde, apenas adubação mineral e esterco bovino, como em todos os outros tratamentos. O delineamento experimental foi em blocos casualizados com quatro tratamentos (três espécies de adubo verde mais a testemunha) e sete repetições. A melhor produção de hastes florais de qualidade ocorreu em roseiras 'Vegas' cultivadas com a adição superficial de feijão guandu no solo e no tratamento controle (somente adubação química). O amendoim forrageiro e o feijão de porco não são indicados para serem plantados em consórcio com roseiras 'Vegas' devido à possível competição por água e nutrientes. Palavras-chave: fl...

“…On the other hand, the decreasing responses of these characteristics after the optimal values was due to the Law of the Maximum, where the excess of a nutrient in the soil may cause toxic effect and/or diminish the effectiveness of others, resulting in reduced values of these variables (Almeida et al, 2015).…”

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 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.…”

“…The adaptation of this legume to adverse conditions such as drought stress, heat or salt stress, its high production of dry biomass, about 40 t ha -1 , vigorous regrowth after cutting and C/N ratio less than 30:1, have justified the increased interest of agronomic researchers on roostertree use as green manure (SOUTO et al, 2008;ANDRADE FILHO, 2012). Research results have demonstrated the potential use of this specie as green manure in the radish crop , carrot (SILVA et al, 2013), coriander , arugula (SOUZA et al, 2016) and lettuce-arugula intercropping (ALMEIDA et al, 2015).…”

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.
