The use of organic fertilizers and the inoculation of mycorrhizal fungi in the cultivation of oil crops is essential to reduce production costs and minimize negative impacts on natural resources. A field experiment was conducted in an Argissolo Amarelo (Ultisol) with the aim of evaluating the effects of fertilizer application and inoculation of arbuscular mycorrhizal fungi on the growth attributes of sunflower (Helianthus annuus L.) and on soil chemical properties. The experiment was conducted at the Federal University of Rio Grande do Norte, Brazil, using a randomized block design with three replicates in a 4 × 2 factorial arrangement consisting of four treatments in regard to application of organic fertilizer (liquid biofertilizer, cow urine, mineral...

Objetivou-se estudar a influência de cultivares de algodão e amendoim e épocas relativas de semeadura em consórcio, verificando-se as relações de competitividade entre as duas culturas. O experimento foi conduzido no município de Missão Velha, CE, Brasil, no campo experimental da Embrapa Algodão, no ano agrícola de 2002. Foram analisados 20 tratamentos com 4 repetições, em delineamento estatístico de blocos ao acaso, em esquema de análise fatorial 2 x 2 x 4 + 2 + 2, cujos fatores foram duas cultivares de algodão (BRS 186 - precoce 3 e BRS 201), duas cultivares de amendoim (L7 e BR-1), quatro épocas de semeadura (0; 7; 14 e 21 dias) mais as testemunhas isoladas das duas cultivares de algodoeiro e amendoim.Considerando os resultados obtidos para renda bruta,...

Relative planting times on the production components in sesame/cowpea bean intercropping in organic system
Provedor de dados: 64
Autores: Araújo,Afrânio César de; Aloufa,Magdi Ahmed Ibrahim; Silva,Apolino José Nogueira da; Pereira,Walter Esfrain; Oliveira,Cosme Jales de.
Aiming at better land use, small farmers usually plant sesame and cowpea bean intercropped with other crops. The aim of this work was to analyze and quantify the influence of four relative planting times of the cowpea bean in intercropping with sesame from the standpoint of their production components, plant productivity and the index of land equivalent ratio (LER). The field experiment was conducted in a randomized blocks with four treatments and four replicates. The treatments were the sesame and the cowpea bean in intercropping with the cowpea bean planted at the same time, 7, 14 and 21days after than the sesame. A greater part of the production components of both the sesame as well the cowpea bean was affected by the intercropping and significant...
