Grapevine productivity, and berry and wine flavonoid concentration, depend on the interactions of cultivar, environment, and applied cultural practices. We characterized the effects that mechanical leaf removal and irrigation treatments had on the…

Emotions are a fundamental step in sensory evaluation and relate to how consumers make purchase decisions or express preference for specific wine styles. Despite their relevance, it is unclear if emotions can be used as a strategy to evaluate quality…

Proximal sensing is used in vineyards to precisely monitor and manage spatial and temporal variability while reducing laborious and repetitive measurements. Soil electrical conductivity (EC) and canopy vegetation indexes are two frequently assessed…

Soil salinity is deleterious for the growth and biological N2 fixation of alfalfa (Medicago sativa L.), but nitrogen fertilization has been beneficial in some cases. This study was conducted to investigate the potential benefit of N fertilization on…

The δ15N natural abundance technique is frequently used to quantify the proportion of legume nitrogen derived from atmospheric fixation (%Ndfa). This method compares the δ15N of a legume with a nonlegume reference plant to estimate the %Ndfa. For…

Fusarium oxysporum f. sp. vasinfectum race 4 is a causal agent of Fusarium wilt of cotton (Gossypium spp.). This study aimed to characterize the existing distribution and frequency of current field populations of F. oxysporum f. sp. vasinfectum race…

Almonds and pistachios are fed upon by a diverse assemblage of lepidopteran insects, several of which are economically important pests. Unfortunately, identification of these pests can be difficult, as specimens are frequently damaged during…

Running speed is a measure of whole-organism performance reflecting relative fitness. For spiders, increased speed translates into enhanced prey capture, mating success and reduced predation risk. In male spiders, leg length increases dramatically…

In California and other agricultural regions that are facing challenges with water scarcity, accurate estimates of crop evapotranspiration (ETc) can support agricultural entities in ongoing efforts to improve on-farm water use efficiency. Remote…

Structural equation modeling (SEM) was employed to analyze the influence of exogenous variables (research and extension (RE), marketing aspects (MA), and infrastructure development (ID)) on the endogenous variable chickpea production development…

Using open-ended questions, this study surveyed over 450 undergraduate students to gain insights into their perceptions of the virtual learning environment due to the COVID-19 pandemic. Results reveal the rapid transition of most courses to online…

Carbon stable isotope composition of berry must at harvest (δ13C) is an integrated assessment of plant water status during grape (Vitis vinifera L.) berry ripening. Measurement of δ13C of grape juice is proposed as an alternative to traditional…

Convolutional neural networks, as a type of deep learning approach, have revolutionized the field of computer vision and pattern recognition through state of the art performance in a large number of classification tasks. Machine learning has been…

During the last decades, essential oils (EOs) have been proven to be a natural alternative to additives or pasteurization for the prevention of microbial spoilage in several food matrices. In this work, we tested the antimicrobial activity of EOs…

This study developed a conceptual model to test the influence of restaurant authenticity on customer perceptions and behaviors at restaurants serving a destination’s authentic regional cuisine. The framework for the study was grounded in social…

Increased demand in consumer choice has resulted in a wide variety of egg selection available in the retail market. Specialty and designer chicken eggs represent a portion of the table egg market that is increasing in size. Egg quality is known to be…

Cantaloupes contaminated with Listeria and Salmonella have caused large scale of foodborne illness outbreaks in recent years. Prior research has shown that heat treatment can be used to reduce microbial contaminates on fruit surfaces. However, no…

Protein–polyphenol interactions play a very important role in wine stability assessment, especially in red varieties. Different polysaccharides can influence these interactions by protecting or disrupting charges and are even used as additives to…

The objective of this study is to analyze the economic impact of Chinese retaliatory tariffs on California’s economy using the Input-Output model. Our model uses state level Impact Analysis for Planning (IMPLAN) dataset along with data from the…

In warmer regions, forcing vines to regrow and shifting fruit ripening to the cooler portion of the growing season can increase the concentration of total fruit anthocyanins (TFA) in red winegrapes, but the effect on anthocyanin composition remains…
