| Com o objetivo de fornecer água potável aos agricultores do Semiárido do Nordeste Brasileiro, estudou-se a viabilidade técnica de um destilador solar no processo de dessalinização de água para consumo humano constituído de um coletor solar para aquecimento de água salina. Foram avalizados dois métodos de condução do fluxo de água do coletor solar para o tanque de evaporação. No Método 1 (M1) o fluxo de água foi constante (1L h-1), mantendo-se um lâmina de 10mm no interior da caixa de alvenaria. No Método 2 (M2) o fluxo de água, advindo do coletor solar, ocorria apenas às 15 horas quando o destilador/condensador era abastecido com água quente advinda do coletor solar, e após o abastecimento o fluxo de água era interrompido. Os volumes de água destilada... |

| The objective of this work was to study the Sunflower growth "Night Sun" in different organic substrates and under different water volumes. The experimental design was randomized blocks in factorial 3x3x5, with three water supply: A1 (50% = 100 ml), A2 (75% = 300 ml), A3 (100% = 400 ml); combined with three types of organic substrates: S1 (33% soil + 33% + 33% cattle manure earthworm castings), S2 (50% soil + 50% earthworm castings), S3 (50% soil + 50% manure) with five replications with three plants per replication. It was observed that there was no significant effect of the volumes of water (A) on the variable plant height (PH). The type of substrate S1 differed from substrate S3, but both did not differered of substrate S2. It is observed that from 33... |

| Sunflower (Helianthus annuus L.) is an annual plant native to the Americas. Is a grain-producing species with a high oil content, which can be used as a source of biodiesel as well as fodder. The cassava is a liquid derived from the cassava flour production. This organic waste can be used in agriculture due to its high content of nutrients such as, K, N, P, Ca, Mg and S and also avoiding harm the environment. The objective of this study was to evaluate the productivity of sunflower using organic fertilization with cassava. The experiment was conducted under field conditions at Lagoa Seca, PB State, and were analyzed the total production (PS), dry mass of the inflorescence (FCA), dry mass of seeds and inflorescence (FSC) and total dry biomass (FT). The... |

| Macassar bean (Vigna unguiculata (L.) Walp) is no longer a culture only for family farmers and is now grown by medium and large producers in the North and Northeast regions, and also in countries of Africa and Asia, especially for its nutritional characteristics. The objective was to make a productive diagnosis of bean Macassar culture and meet some techniques used by bean producers in the municipality of Parari, Paraíba State, Brazil. The survey was conducted in 2011 with questionnaires to the 50 producers. It was found that most farmers, 45% has an area of 2 hectares for common bean cultivation, as follows: 55% of farmers get their seeds with property of neighbors, while 45% of them cultivate this legume in clay soils. Almost 85% use the bean as... |
