1. Cover cropping system and mulching can shape soil microbial status in fruit orchards
ABSTRACT The use of cover crop in agricultural fields has been well elucidated, especially regarding nitrogen fixation from legume crops and their function as weed protection. Furthermore, to cover crops can benefit the soil microbial community. This study aimed to evaluate and compare the benefits of mulching and cover cropping systems on soil microbial gro

2. COPPER OXYCHLORIDE APPLIED ALONE TO CONTROL CITRUS BLACK SPOT
RESUMO A Mancha Preta dos Citros causada pelo fungo Phyllosticta citricarpa é uma doença que causa lesões em frutos e queda prematura em estágios mais severos. O uso de fungicidas sistêmicos é a principal medida de controle, porém a busca por um controle alternativo pode envolver a aplicação de fungicidas cúpricos isoladamente, em intervalos reduzi

5. HARVESTING FRUITS USING A MOBILE PLATFORM: A CASE STUDY APPLIED TO CITRUS
ABSTRACT Harvesting fruits and vegetables has been a challenge. Mobile platforms for harvesting vegetables and fruits have been used, but with some limitations, such as their applicability for a certain time of the year and for a specific crop. A mobile platform was initially developed for harvesting fresh market tomatoes, mainly staked in Brazil. However, a

6. Impacts of climate change on drought: changes to drier conditions at the beginning of the crop growing season in southern Brazil
ABSTRACT The intensification of drought incidence is one of the most important threats of the 21st century with significant effects on food security. Accordingly, there is a need to improve the understanding of the regional impacts of climate change on this hazard. This study assessed long-term trends in probability-based drought indices (Standardized Precip

7. Changes in Soil Organic Carbon Fractions in Response to Cover Crops in an Orange Orchard
ABSTRACT The cultivation of cover crops intercropped with fruit trees is an alternative to maintain mulch cover between plant rows and increase soil organic carbon (C) stocks. The objective of this study was to evaluate changes in soil total organic C content and labile organic matter fractions in response to cover crop cultivation in an orange orchard. The

8. Effects of chemical treatments and environmental factors on seed dormancy and germination of shepherd's purse (Capsella bursa-pastoris (L.) Medic.)
Shepherd's purse (Capsella bursa-pastoris) is a problematic weed in citrus orchards and crop fields in northern Iran. In a series of laboratory and greenhouse experiments, we evaluated the effects that treatment with gibberellic acid (GA3) and potassium nitrate (KNO3), as well as environmental factors, including temperature, the duration of pre-chilling (wet

9. Identification and characterization of viroids in 'Navelina ISA 315' sweet orange
To date, seven species of viroids have been described infecting Citrus. However, only Citrus exocortis viroid (CEVd), Hop stunt viroid (HSVd) and Citrus dwarfing viroid (CDVd) have been reported in this crop in Brazil. The aim of our work was to identify and characterize viroids infecting plants of 'Navelina ISA 315' sweet orange cultivar grafted on 'Rangpur

10. Use of horticultural practices in citriculture to survive Huanglongbing.
Citriculture is one of the major activities of the Brazilian agribusiness found throughout the entire country in different production environments. The presence of the Huanglongbing (HLB), reported in Brazil in 2004, has led to severe losses in important producing regions, challenging the sustainability of the citrus chain. Current control strategies are bas

11. Relacoes entre a producao de laranjeira 'Westin' e as precipitacoes em Botucatu, SP.
O trabalho estuda a correlacao entre a producao de um pomar de laranja, plantado no altiplano de Botucatu, SP, com as precipitacoes que ocorrem dezesseis meses antes da colheira e a idade do pomar. As plantas eram de laranjeira doce (Citrus sinensis (L.) Osbeck), variedade Westin, de clone nucelar, enxertadas em porta-enxerto de limoeiro 'Cravo' (Citrus limo

12. Caracterização molecular e diversidade de fitoplasmas em pomares de citros no Estado de São Paulo / Molecular characterization and diversity of phytoplasmas in citrus orchards in the Sao Paulo state
Recentemente, um fitoplasma do grupo 16SrIX foi associado a plantas de citros com sintomas de huanglongbing (HLB) no Estado de São Paulo. No entanto, em razão da ampla diversidade de fitoplasmas que tem se observado em várias culturas no Brasil, seria possível que além do fitoplasma do grupo16SrIX, outros fitoplasmas também pudessem estar associados a
