Potassium fertilization for pineapple: effects on plant growth and fruit yield
Provedor de dados: 94
Autores: Teixeira,Luiz Antonio Junqueira; Quaggio,José Antonio; Cantarella,Heitor; Mellis,Estêvão Vicari.
A field experiment with pineapple (Smooth Cayenne) was carried out on an Ultisol located in the city of Agudos (22º30'S; 49º03'W), in the state of São Paulo, Brazil, with the objective of investigating the effects of rates and sources of potassium fertilizer on plant growth and fruit yield. The experiment was a complete factorial design (4x3) with four rates (0, 175, 350, and 700 kg ha-1 of K2O) and three combinations of K sources (100% KCl, 100% K2SO4, and 40% K2SO4 + 60% KCl). Plant growth and fruit yield were evaluated. Biomass accumulation of pineapple plants was impaired by chlorine added with potassium chloride. Fruit yield increased with potassium fertilization. At high rates of K application, fertilization with K2SO4 showed better results than with...

Potassium fertilization for pineapple: effects on soil chemical properties and plant nutrition
Provedor de dados: 94
Autores: Teixeira,Luiz Antonio Junqueira; Quaggio,José Antonio; Cantarella,Heitor; Mellis,Estêvão Vicari.
A field experiment was carried out on an Ultisol located at the city of Agudos (22º30'S; 49º03'W), in the state of São Paulo, Brazil, in order to determine the effects of rates and sources of potassium fertilizer on nutritional status of 'Smooth Cayenne' pineapple and on some soil chemical properties. The experiment was a complete factorial design with four rates (0, 175, 350, and 700 kg ha-1 of K2O) and three combinations of K sources (100% KCl, 100% K2SO4 and 40% K2SO4 + 60% KCl). Soil samples were taken from the depths 0-20 cm, 20-40 cm and 40-60 cm at planting and 14 months after. Nutritional status of pineapple plants was assessed by means of tissue analysis. Soil K availability increased with application of K fertilizer, regardless of K sources. Soil...

Sensory and physicochemical characteristics of low sodium salami
Provedor de dados: 63
Autores: Almeida,Marcio Aurelio de; Villanueva,Nilda Doris Montes; Pinto,Jair Sebastião da Silva; Saldaña,Erick; Contreras-Castillo,Carmen J.
ABSTRACT The aim of the present study was to develop low sodium salami prepared with pork, low-fat beef and a small quantity of pork back fat (150 g kg−1). Sodium chloride (NaCl) was replaced by potassium chloride (KCl) and calcium chloride (CaCl2), and salamis were tasted to obtain low-salt salami with sensory characteristics similar to those found in commercial ones. Salamis were prepared following seven different treatments. Treatments included five different combinations of KCl and CaCl2 which varied from 5 g kg−1 to 10 g kg−1 and two controls containing high (25 g kg−1) and low (10 g kg−1) concentrations of NaCl. The right level of saltiness of each treatment was evaluated on “just-about-right” (JAR) scales and analyzed by Penalty Analysis. The...

Sugarcane cultivation with source potassium low water-soluble
Provedor de dados: 1
Autores: Korndorfer, Gaspar Henrique; Pereira, Hamilton Seron; Duarte, Ivaniele Nahas; Pinto, Laerte Rocha Neves; Fonseca, Luciano Ferreira da.
Thermopotash is a fertilizer with low solubility but has a release level compatible with plant demands. This study aimed to compare the effect of Thermopotash to that of KCl in sugarcane. Field work was conducted during two crop seasons, in a randomised block design. Treatments were applied to the bases of the furrows before planting the sugarcane, arranged in a 2 x 5 factorial design to evaluate two K sources (TK47 - Thermopotash, KCl - potassium chloride) at five levels of K (0, 50, 100, 150, and 200 kg ha-1 K2O). The variables analysed included leaf and soil K, Ca, Mg and Si, soil pH and productivity. The effects of the TK47 fertilizer on sugarcane stalk production were not initially superior to that of the soluble source, but over time, differences...

Comparative study of the pathogenicity of seabed isolates of Fusarium equiseti and the effect of the composition of the mineral salt medium and temperature on mycelial growth
Provedor de dados: 58
Autores: Palmero,D; Cara,M. de; Iglesias,C; Gálvez,L; Tello,J.C.
The pathogenicity of seven strains of Fusarium equiseti isolated from seabed soil was evaluated on different host plants showing pre and post emergence damage. Radial growth of 27 strains was measured on culture media previously adjusted to different osmotic potentials with either KCl or NaCl (-1.50 to - 144.54 bars) at 15º, 25º and 35º C. Significant differences and interactive effects were observed in the response of mycelia to osmotic potential and temperature.

Tolerance of crambe (Crambe abyssinica Hochst) to salinity and water stress during seed germination and initial seedling growth
Provedor de dados: 64
Autores: Silva,Martha Freire da; Araújo,Eduardo Fontes; Silva,Laércio Junio da; Amaro,Hugo Tiago Ribeiro; Dias,Luiz Antônio dos Santos; Dias,Denise Cunha Fernandes dos Santos.
ABSTRACT Crambe is an oilseed plant whose oil is suitable for various industrial purposes, such as production of biodiesel, plastics, rubbers, and cosmetics. There are reports of the rusticity of this species and its potential for growth in arid and semi-arid environments, where water scarcity and soil salinity are common. However, studies regarding the tolerance of its seeds to these stresses and the physiological responses triggered during germination and seedling establishment under these conditions are incipient. The objective of this study was to evaluate the tolerance of crambe seeds to water deficit and salt stress during germination and early seedling development, as well as to investigate the role of antioxidant enzymes on tolerance to these...
