A desagregação de partículas do solo afeta a sua capacidade produtiva, resultando em processos de compactação, erosão e perdas de nutrientes. Neste estudo, foi avaliada a qualidade e estabilidade dos agregados de um Latossolo Amarelo, em delineamento de blocos ao acaso, representado por Urochloa decumbens e Urochloa brizantha, na presença e ausência de adubação mineral, e por duas formas de amostragem (fileiras e entre as fileiras), em três profundidades de amostragem. As amostras indeformadas de solo coletadas foram destorroadas, passadas em peneira de 9,52 mm e, após secagem, em peneiras de 2,00 mm; 1,00 mm; 0,50 mm e 0,25 mm, obedecendo às seguintes classes de diâmetro: 9,52-2,00 mm; 2,00-1,00 mm; 1,00-0,50 mm e 0,50-0,25 mm, por peneiragem seca. Estes agregados foram, também, separados por peneiragem úmida, sendo, ainda, determinada a argila dispersa e a massa seca de raízes. Os agregados maiores que 2,00 mm apresentaram estabilidade elevada, na camada de 0,00-0,05 m, em comparação aos agregados de menores classes, não havendo efeito do local de amostragem e de adubação sobre o tamanho e estabilidade dos agregados. Concluiu-se não haver diferença entre as duas espécies estudadas, forma de coleta das amostras e adubação, na formação e estabilidade de agregados.

. 2017. Gas exchange and productivity of yellow passion fruit irrigated with saline water and fertilized with potassium and biofertilizer. Cien. Inv. Agr. 44(2): 168-183. The salinity of irrigation water can affect the growth and development of most plants of commercial interest. Aiming to study these aspects in passion fruit culture, an experiment was performed to evaluate the effects of bovine biofertilizer and potassium fertilization on gas exchange and production of the passion fruit 'BRS Giant Yellow' irrigated with non-saline and saline water. The treatments were arranged in randomized blocks with sub-subdivided plots using the 2×(3×5) scheme, which refers to two levels of electrical conductivity of the irrigation water as the main plot (0.35 and 4.00 dS m -1 ) and the combination of three potassic fertilization practices (without fertilization, fertilized with conventional and slow release KCl) with five doses of bovine biofertilizer (0, 25, 50, 75 and 100% of dose of 15 L m -2 ) in the subplots, with three replicates and 12 plants per plot. The physiological variables and the productivity were evaluated in two harvests, and the data were submitted to statistical evaluation of samples repeated in time. The application of bovine biofertilizer and potassium in soil with a sandy texture irrigated with saline water did not inhibit the degenerative effect of the salts on the photosynthetic rates of the plants. The salinity of the irrigation water reduced stomatal conductance, transpiration and net photosynthesis of the plants, but in the second crop, the instantaneous water use efficiency was higher. Although the productivity decreased from the first to the second harvest, the biofertilizer associated with potassic fertilization increased the yield of the crop, which surpassed the average of Brazil, the Brazilian Northeast and the State of Paraiba, Brazil.
RESUMO:O cultivo do milho pipoca (Zea mays everta) no Brasil aparece como uma opção para o produtor rural, apresentando maior rentabilidade econômica face ao melhor preço alcançado no mercado comparado com o do milho comum. O presente trabalho objetivou obter quantidade de adubo orgânico conciliada a um espaçamento que proporcione uma melhor produtividade de grãos de milho pipoca. A pesquisa foi conduzida na Estação Experimental da Empresa Estadual de Pesquisa Agropecuária da Paraíba (EMEPA-PB), no município de Alagoinha -PB, em um Luvissolo Crômico Pálico abrúptico. O delineamento experimental foi em blocos casualizados, com dimensões 60,00 m × 5,00 m, com parcelas de 5,00 m × 5,00 m, arranjados no esquema fatorial 2 × 5, com três repetições. Foram testados dois espaçamentos entre fileiras (1,00 m e 0,80 m), com espaçamento entre plantas de 0,20 m e cinco quantidades de adubo orgânico: 0, 5, 10, 15, 20 t ha -1 de esterco bovino. Utilizou a cultivar de milho CMS 42 da Embrapa. Foram avaliados: altura, diâmetro do colmo, produtividade e índice de capacidade de expansão dos grãos. Os dados obtidos foram submetidos à análise de variância, sendo a influência do fator Adubação testado pela regressão polinomial e a influência do fator Espaçamento pelo teste F a 5%. A altura de plantas, os aumentos foram proporcionais ao aumento das quantidades de adubo orgânico aplicados, já o melhor diâmetro de colmo foi obtido com 5 t ha -1 , a maior produtividade de grãos foi obtida com 18,31 t ha -1 no espaçamento 0,80 × 0,20 m. PALAVRAS-CHAVE:Esterco bovino, espaçamento, Zea mays everta. ABSTRACT: The cultivation of popcorn (Zea mays everta) in Brazil appears as an option for farmers, with higher economic profitability over the best price achieved in the market compared to the common corn. This study aimed to obtain quantity of organic fertilizer reconciled to a spacing that provides better productivity of popcorn kernels. The research was conducted at the Experimental

The indiscriminate use of mineral fertilizers in papaya orchards has increased production costs, and the use of arbuscular mycorrhizal fungi is a promising alternative to reduce such expenses. Therefore, the present research aimed at studying the efficiency of arbuscular mycorrhizal fungi (AMF) on dry matter and nutrient accumulation in Sunrise Solo papaya seedlings, by applying doses of P2O5 (triple superphosphate) that are harmful to the symbiosis. The experiment was carried out in a protected environment and was set up in a randomized block design with four replications, and consisted of four P2O5 doses (0, 672, 1386 and 2100 mg dm-3), three mycorrhizal fungi species (Gigaspora margarita, Entrophospora colombiana and Scutellospora heterogama) and the control treatment (mycorrhiza-free). Shoot and root dry matter as well as nitrogen, phosphorus and potassium contents in leaf and root tissues were assessed. Mycorrhizal inoculation promoted a 30% increase in shoot dry matter in relation to the control treatment. Mycorrhizal fungi promoted increases in leaf and root nitrogen content up to 672 mg dm-3 P2O5. Inoculation of E. colombiana favored the highest gains in root and shoot dry matter. P2O5 fertilization increased foliar and root phosphorus content.
