“…The increase in productivity from the supply of poultry litter is a result of the addition of the macro-and micronutrients provided by that material. In addition to the chemical improvement, the organic input contributes to the physical conditioning of the soil (VALADÃO et al, 2011), allowing greater moisture retention and favouring crop production. Along the same lines, Rós (2014) found that the use of 5.79 t ha -1 chicken manure prompted a total productivity of 25.6 t ha -1 in sweet potato roots.…”

In the northern region of Brazil, information for the sweet potato regarding suitable soil management, especially organic fertilisation and intercropping with species of green manure, are still in the early stages. The aim of this research therefore, was to evaluate the effect of poultry litter on the yield of sweet potato roots grown under a monocrop system and when intercropped with sunn hemp (Crotalaria juncea) under the soil and climate conditions of the State of Roraima. The experiment was carried out in the field from August to December of 2014, in the Sector for Olericulture of the School of Agricultural Technology, on the Murupu Campus of UFRR in the town of Boa Vista, Roraima. A randomised block experimental design was used, with three replications, in a (5 × 2) + 1 factorial scheme, representing five doses of poultry litter (0, 5, 10, 15 and 20 t ha -1 ), with sweet potato as both a monocrop and intercropped with sunn hemp, and one additional treatment with organic and mineral fertiliser. Slips of the Granfina variety of sweet potato were used for planting. Seeds of sunn hemp were sown in double rows between the rows of sweet potato 30 days after planting the slips, with the first cutting carried out 90 days after sowing. The addition of poultry litter to the soil increased the total production of sweet potato roots for the crop planted in Roraima, whether intercropped or not with sunn hemp. Despite the benefits to sweet-potato yield from the addition of poultry litter and the intercrop with sunn hemp, total productivity was greater in the additional treatment that received organic and mineral fertiliser.Resumo: Na região Norte, as informações para a batata-doce quanto ao manejo adequado do solo, principalmente sobre a fertilização orgânica e o consórcio com espécies de adubos verdes, ainda são incipientes. Neste sentido, objetivou-se com esta pesquisa avaliar o efeito da cama de aviário sobre o rendimento de raízes de batata-doce, cultivada em sistema solteiro e consorciada com Crotalaria juncea, nas condições edafoclimáticas de Roraima. O experimento foi realizado em campo no período de agosto a dezembro de 2014, no setor de Olericultura da Escola Agrotécnica, Campus Murupu-UFRR, município de Boa Vista-RR. O delineamento experimental empregado foi o de blocos casualizados, com três repetições, usando o arranjo fatorial (5 × 2) + 1, referentes a cinco doses de cama de aviário (0; 5; 10; 15 e 20 t ha -1 ), com a batata-doce em monocultivo e consorciada com a crotalária, e um tratamento adicional com adubação orgânica e mineral. No plantio da batata-doce foram utilizadas ramas da variedade Granfina. As sementes de crotalária foram semeadas em linhas duplas nas entrelinhas da batata-doce, aos 30 dias após o plantio das ramas, sendo o seu primeiro corte efetuado 90 dias após sua semeadura. A adição de cama de aviário ao solo elevou a produtividade total de raiz de batata-doce no lavrado de Roraima, independente da ausência ou presença do consórcio com crotalária. Apesar da ação benéfica da adição de cama-d...

“…Poultry litter includes all the material used as floor covering in poultry production facilities and is contaminated with bird droppings, leftover feed and feathers (MENEZES et al, 2004).Composting this residue for use as a solid organic fertilizer minimizes environmental damage that might have otherwise resulted from the accumulation of this material (ÁVILA et al, 2007).Using poultry litter in agriculture improves the yield and quality of various species (BOATENG et al, 2006;ADELI et al, 2007;SILVA et al, 2011;VIEIRA et al, 2015) such as tomatoes (MUELLER et al, 2013) and improves attributes of the soil (VALADÃO et al, 2011).…”

ABSTRACT:The number of growers and planted area dedicated to organic farming have increased considerably. Consequently, demand has increased for alternative organic composts in terms of quantity and new options for direct use with crops. Making use of local industrial byproducts is also important throughout Brazil and the rest of the world. Therefore, it was evaluated the effect of eight types of organic composts, produced with different percentages of poultry litter and crushed sugarcane on tomato yield and quality. (0, 10, 20, 30, 40, 50, 50, 60 and 70%) yielding eight types of alternative Bokashi used as organic compost in the production of two tomato cultivars (Santa Clara and the Verano hybrid). It was found that the various formulations of alternative Bokashi, except the alternative Bokashi B1, strengthened components of tomato yield and quality. We found that composts of poultry litter and crushed sugarcane increase tomato yield and quality and can be and excellent alternative, especially for organic farmers.

“…Devido à grande oferta de resíduos oriundos dos criatórios de aves nas diversas regiões do estado de Santa Catarina, a cama de aviário surge como uma boa alternativa para o suprimento de N, P e K. Além de fornecer nutrientes, a cama de aviário pode melhorar os atributos físicos do solo (ESPANHOL et al 2007, VALADÃO et al 2011, atuando também como condicionador de solo. Uma das vantagens do uso do adubo orgânico é a liberação de P mais lenta e sincronizada às necessidades da planta quando comparada ao uso de adubo solúvel, o que reduz a adsorção deste nutriente pelas partículas reativas do solo.…”
