“…When considering that potassium stimulates the maintenance of ionic balance or osmoregulation of plants, turgidity cell, control the opening and closing of stomata, plant resistance to water stress and soil salinity (Gurgel et al, 2010), the application of a source of slow release of macronutrient should also attenuate the depressive effects of salts in the different phases of phenological Souza et al 2995 plants. The coated or protected fertilizers with polymers release the partially nutrient, but continuously during the crop cycle, also, reduction in losses by leaching, volatilization and result in greater efficiency in soil water absorption, solubility and availability to the plants (Zahrani, 2000).…”

The monitoring of plants growth constitutes an important activity during the crops formation, including the yellow passion fruit. In this direction, an experiment was carried out in Remigio, Paraiba State, Brazil, to evaluate the effects of saline water irrigation, bovine biofertilizer and potassium on yellow passion fruit growth plants and soil salinity. Treatments were arranged in randomized block with three replications and 12 plants per plot, using factorial design 2 x 2 x 2, relative electrical conductivity of irrigation water of 0.35 to 4.00 dS m

Resumo -Os solos tropicais, normalmente pobres em potássio (K), quando cultivados com soja (Glycine max L.) demandam adubação potássica para obtenção de produtividades satisfatórias. Objetivou-se com este trabalho avaliar o efeito de doses de K e níveis de umidade do solo nos componentes de produção da soja. O experimento foi realizado em casa de vegetação e os tratamentos foram dispostos em um delineamento em blocos casualizados em esquema fatorial (5 x 3), com cinco repetições. Um vaso com 5 dm 3 de solo com duas plantas compôs a parcela experimental. O primeiro fator correspondeu às doses de K (0; 30; 60; 120 e 180 mg dm -3 ) e o segundo fator as faixas de umidade do solo (35 a 40; 47,5 a 52,5; e 60 a 65% do volume total de poros). Foram avaliados: rendimento de grãos, peso de cem grãos, número total de grãos por vaso, teor de K no grão, número de vagens viáveis. Houve resposta da soja à adubação potássica, com aumento do rendimento de grãos, massa de cem grãos, teor de K no grão e número de vagens viáveis. O total de grãos por vaso atingiu valor máximo na combinação dos limites superiores de cada fator de estudo. O K reduziu os efeitos do défice hídrico na cultura da soja. Palavras-chave -Glycine max. Adubação potássica. Solo-umidade.Abstract -The tropical soils, usually poor in potassium (K), demand potassium fertilization when cultivated with soybean (Glycine max L.) to obtain satisfactory yields. The aim of this study was to evaluate the effects of K doses and soil humidity levels on soybean agronomic characteristics. The experiment was carried out in a greenhouse, in pots with two plants, containing 5 dm 3 of soil. The experimental design was completely randomized block with treatments in a 5 x 3 factorial arrangement. The K doses were 0; 30; 60, 120 and 180 mg dm -3 , and the soil humidity ranged from 35 to 40; 47.5 to 52.5; and 60 to 65% of the total porosity. The characteristics appraised were: grain yield, weight of a hundred grains, total number of grains per pot, K level in the grain, number of viable pods. There was soybean response to the potassium fertilization, with increase of the grain yield, mass of a hundred grains, K level in the grain and number of viable pods. The grain total per pot reached maximum value in combination of the upper limits of each study factor. The K reduced the water deficit effects on the soybean.
