“…The practice of green manuring has been shown to be important for different crops, whether they use intercropping or crop rotation systems. This is due to the innumerable benefits provided by this practice, such as the improvements in the physical, chemical and biological aspects of soil, increased productivity, and weed control Dantas et al, 2015;Tao et al, 2017). However, few studies have shown the influence of green manures on the yield and quality of organic foods such as tomatoes.…”

“…2017 Ambrosano et al, 2013). Intercropping usually results in biomasses in the lower part of this range (Blaise et al, 2005a;Dantas, 2015) The greater biomass of sunnhemp treatments contributed to their higher nutrient recycling than that of pigeon pea, in spite of higher dry matter concentrations of N and P in pigeon pea ( Table 1). The contribution of nitrogen was particularly important, part of which may have come from symbiotic N 2 fixation (Perin et al 2006, Espana et al 2006Faria et al, 2007) which could lead to net increases in soil N availability.…”

Yam (Dioscorea cayennensis Lam.) is a promising crop for small growers in the Northeast of Brazil, but productivities are limited due to low fertilization rates. Green manure could be an alternative due to its low cost and high availability. However, there is little information available regarding the effects of green manures on the productivity of yam. The quality and yield of yam tubers, “da costa” variety, were evaluated under application of three different green manures and a control treatment: 1) yam intercropped with sunn hemp (Crotalaria juncea L.); 2) yam intercropped with pigeon pea (Cajanus cajan L.); 3) yam intercropped with a combination of sunn hemp and pigeon pea; and 4) conventional yam crop system. The experiment was laid out in a randomized block design, with four repetitions. The data was submitted to analysis of variance and averages compared by Tukey´s test at 5%. Percentage values were transformed into arc sen (x/100)0.5. Sunn hemp and the combination of sunn hemp with pigeon pea produced the highest green manure biomasses (3.8 and 3.6 t DM ha-1, respectively) versus 2.1 t ha-1 with the use of only pigeon pea. However, the N concentration was higher in pigeon pea than in sunn hemp (26 and 16 g kg-1). Intercropping with pigeon pea led to the highest yield for total tubers (33.1 t ha-1), for market quality (32.2 t ha-1) and standard exportation quality tubers (23.0 t ha-1).

“…Machado e Margarido (2014) constataram que o consórcio de canade-açúcar com diferentes culturas (milho, feijão e mandioca) não influenciou a altura da cana e o Grau Brix. Dantas et al (2015) observaram que as leguminosas amendoim forrageiro (Arachis pintoi), calopogônio (Calopogonium mucunoides), xiquexique (Crotalaria anagyroides), crotalária júncea (Crotalaria juncea), estilosantes 'Campo Grande' (mistura física de sementes de Stylosanthes capitata e S. macrocephala) e guanduanão (Cajanus cajan), introduzidas nas entrelinhas da cana de açúcar, em manejo orgânico, em sistema de consorciação, com semeadura tardia dos adubos verdes, não interferem na produtividade de colmos, produção de açúcar e qualidade do caldo da cana planta e da primeira cana soca.…”

RESUMO -O consócio de culturas tem sido uma prática constante, principalmente pelos pequenos produtores, visando o aproveitamento da área, os benefícios ecológicos e ganhos econômicos. Contudo, deve-se levar em consideração a competição por água, luz e nutrientes que pode ser um fator limitante para o sucesso do consórcio. O objetivo deste trabalho foi avaliar a produção de forragens de cana-de-açúcar e feijão-guandu cultivados em monocultivo e consorciados. O delineamento experimental foi em blocos casualizados, com três tratamentos e cinco repetições. Os tratamentos testados foram: cana-de-açúcar em monocultivo, feijãoguandu em monocultivo e cana-de-açúcar consorciada com feijão-guandu. Os parâmetros avaliados nas plantas de feijão-guandu foram: altura das plantas, número de hastes, massa verde do caule, massa verde das folhas, massa verde da parte aérea, massa seca do caule, massa seca das folhas e massa seca da parte aérea. Na canade-açúcar, foram avaliados os seguintes parâmetros: altura da planta, diâmetro do colmo, número de folhas por planta, largura e comprimento da maior folha, número de plantas por metro linear e produtividade de massa verde. A altura das plantas no segundo corte e o número de hastes no primeiro corte das plantas de feijão-guandu foram superiores no tratamento consorciado com a cana-de-açúcar. Entretanto, as produtividades de massa fresca e seca das folhas foram superiores no tratamento em monocultivo. O número de folhas de cana-de-açúcar foi maior no cultivo consorciado e a produtividade de massa verde no monocultivo. O cultivo consorciado de cana-de-açúcar e feijão-guandu, no espaçamento de 1 m entre linhas alternadas, não aumenta a oferta de forragem destas culturas.ABSTRACT -The partnership of cultures has been a constant practice, primarily by small producers, aimed at the exploitation of the area, the environmental benefits and economic gains. However, one must take into consideration the competition for water, light and nutrients that can be a limiting factor to the success of the Consortium. The aim of this study was to evaluate the agronomic performance of sugarcane and pigeon pea grown in monoculture and intercropping for animal feed. The experimental design was randomized blocks, with three treatments and five replications. The treatments tested were: sugarcane in monoculture, pigeon pea in monoculture and sugarcane intercropped with pigeon pea. The parameters evaluated in plants of pigeon pea beans were: height of plants, number of stems, green mass of the stem, green mass of leaves, green mass, dry mass of the stem, leaf dry mass and dry mass of the shoot. In sugarcane were evaluated
