| ABSTRACT Intercropping systems of beet and green cowpea are beginning to be implemented in the northeastern semi-arid region in Brazil. The great challenge is to know if there is agro-economic efficiency in these systems when fertilized with organic matter produced by spontaneous species of the Caatinga biome. Thus, the objective of this research was to evaluate the effect of green manuring using different amounts of hairy woodrose (Merremia aegyptia) in the association of beet with green cowpea under the semi-arid conditions. The experiment was carried out at the Rafael Fernandes Experimental Farm, rural area of Mossoró, RN, Brazil, in the period of September-December 2015, in a randomized complete block design with four treatments and five replicates.... |

| ABSTRACT Polycultures from broadleaves with tuberoses are being used in vegetable crop production systems in the semiarid region of Potiguar. The challenge is to determine whether these systems are productively viable when fertilized with organic matter produced by spontaneous species of the Caatinga biome. The objective of this study was to evaluate the agro-economic performance of arugula (A), carrot (C), and coriander (Co) polycultures fertilized with hairy woodrose biomass incorporated into the soil under different population densities among the component crops. The experimental design was a randomized complete block with four replications, with the treatments arranged in a 4 × 4 factorial scheme, from the combination of four amounts of hairy woodrose... |

| ABSTRACT Beet and lettuce are industrial vegetable crops valued for their high mineral, vitamin and fiber contents and for their additional health benefits. These crops are usually grown in intercrops in family production systems in a sustainable manner in semi-arid regions. This work aimed to evaluate the effects of incorporating different levels of hairy woodrose, as a green manure, on the agro-economic sustainability indicators of lettuce-beet intercrops, planted in different spatial arrangements and involving two successive croppings. The experimental design was a randomized complete blocks with treatments arranged in a 4 x 3 factorial scheme, corresponding to four hairy woodrose levels incorporated into the soil (6, 19, 32 and 45 t ha-1, dry basis)... |

| Este trabalho foi conduzido no período de julho a novembro de 2009, na Fazenda Experimental Rafael Fernandes, da Universidade Federal Rural do Semi-Árido UFERSA, Brasil, objetivando-se avaliar a produção da beterraba (Beta vulgaris L.) fertilizada com jitirana (Merremia aegyptia L.) sob diferentes doses e tempos de sua incorporação ao solo. O delineamento experimental adotado foi em blocos completamente casualizados e os tratamentos arranjados em esquema fatorial 4 x 4 + 1 com 3 repetições, com 72 plantas por parcela, sendo o primeiro fator constituído pelas doses de jitirana (5,4; 8,8; 12,2 e 15,6 t ha-1 em base seca), o segundo pelos tempos de sua incorporação ao solo (0, 10, 20 e 30 dias após a semeadura - DAS) e o tratamento adicional com adubação de... |

| ABSTRACT This study aimed to evaluate the agro-economic efficiency of agrosystems of two croppings of arugula (A) and two of lettuce (L) intercropped with carrot (C) under different biomass amounts of roostertree incorporated into the soil and population density proportions between the component crops. The experimental design was a randomized block with four replications, with the treatments arranged in a 4 × 4 factorial scheme. The first factor was made up of the amounts of roostertree biomass incorporated into the soil (10, 25, 40 and 55 t ha-1 on a dry basis) and the second factor by the population density proportions of the component crops in the polycultures (50A-50C-50L%, 40A-50C-40L%, 30A-50C-30L% and 20A-50C-20L% of the population recommended for... |
