Analysis of Petiole Sap Nutrients Using Rapid and Standard Methods and Its Rela...

Currently, fertilization decisions in apple orchards are based on soil and leaf analyses while the leaf material is sampled after the growing season, usually in June–July (90–110 days after full bloom). This approach is inefficient, as the information becomes available later than the growing season and is therefore only useful in supporting fertilization decisions for the next year, not the current one. To esta...

Single and basal crop coefficients for estimation of water use of tree and vine...

This paper reviews the research on the FAO56 single and basal crop coefficients of fruit trees and vines performed over the past twenty-five years and focus on Mediterranean and warm temperate trees and vines. Two companion papers (López-Urrea et al., (2023) Single and basal crop coefficients for estimation of water use of tree and vine woody crops with consideration of fraction of ground cover, height, and tra...

Single and basal crop coefficients for estimation of water requirements of subt...

This paper provides an overview of the research carried out over the last 25 years on the FAO56 single and basal crop coeffi- cients of subtropical and tropical orchards and plantations of cactus pear, dragon fruit, fig, jujube, passion fruit, pomegranate, cape gooseberry, cherimoya, guava, longan, lychee, mango, papaya, acerola, carambola, cashew, cacao, coffee, jaboticaba, jatropha, macadamia, açai palm, coco...

Single and basal crop coefficients for temperate climate fruit trees, vines and...

The objective of the present review article was to update the standard single (K c ) and basal (K cb ) crop coefficients published in the FAO Irrigation and Drainage Paper No. 56 (FAO56), focusing on temperate climate fruit trees (pome, stone and nut fruit trees), vines and shrubs (kiwi, hop and blue- and blackberries). Standard conditions refer to crops grown in medium to large fields, having enough fetch for ...

Brown Rot Caused by Gnomoniopsis smithogilvyi (syn. Gnomoniopsis castaneae) at ...

The European chestnut tree (Castanea sativa Mill.) has great economic importance, mostly due to the recognized nutritional value of its fruit. Thus, the development and improvement of the techniques of the production, preservation, and control of the diseases/pests of chestnut trees is a topic of great interest to producers, companies, researchers, and consumers to ensure the quality of this exceptional fruit. ...

Utilização da iluminação LED para otimizar a frutificação do morangueiro na tec...

Nutrient Content with Different Fertilizer Management and Influence on Yield an...

Assessing a plant’s nutritional status and fertilizer rates and types that can optimize fruit quality and yield are critical in intensive apple orchards. The aim of this work was to identify correlations between nutrients in the different organs that allow the early diagnosis of the nutritional status and to assess the impact on the optimal nutrient content in apple leaves, as well as in the yield and quality o...

Efeito do genótipo na emissão de lançamentos em raízes de framboesa

Este estudo foi realizado com o objetivo de maximizar a obtenção de plantas a partir dos sistemas radiculares de plantas de framboesa. É do interesse das empresas viveiristas perceber como se comportam os diferentes genótipos na obtenção de lançamentos de raiz. O ensaio foi realizado numa estufa no Instituto Nacional de Investigação Agrária e Veterinária (INIAV, I.P.), numa bancada de enraizamento, com divisóri...

Arquitetura floral do morangueiro em cultura protegida e em substrato na região...

A possibilidade de se estimar o grau de desenvolvimento da planta de morangueiro e prever o seu potencial de floração e de frutificação tem particular importância por permitir ao produtor planear e gerir de forma mais eficiente os recursos disponíveis e atuar de forma mais eficaz. O objetivo deste trabalho foi avaliar a arquitetura das plantas de morangueiro do viveiro e, após a plantação, a sua evolução ao lon...
