Evaluation of the SPAD Value in Faba Bean (Vicia fabaL.) Leaves in Relation to Different Fertilizer Applications

Plant Production Science, 2003
The correlations of the reading of a portable chlorophyll meter (SPAD-502) with the chlorophyll and N contents of leaves of two faba bean (Vicia fabaL.) cultivars, Japanese (Ryousai-issun) and Egyptian (Cairo 241), were examined.

Punicalagin‐enriched edible coatings from revalorized pomegranate peels for quality enhancement of fresh‐cut celery

Journal of the Science of Food and Agriculture, EarlyView.
Abstract BACKGROUND Pomegranate peel is a rich source of phenolics, particularly punicalagin, but its valorization for fresh produce preservation requires stabilization. This study aimed to develop and evaluate freeze‐dried encapsulates of pomegranate peel extracts as ingredients in edible coatings for fresh‐cut celery. Pomegranate peels were extracted

Straw Return Combined With Nitrogen Fertilizer Application Improve Nitrogen Utilization Efficiency by Regulating Soil Physical and Chemical Properties in Spring Maize

Land Degradation &Development, EarlyView.
ABSTRACT Straw return (SR) and controlled‐release nitrogen fertilizers application can improve soil structure, enhance soil water retention, and promote crop growth. However, the mechanisms through which SR and controlled‐release nitrogen fertilizers application jointly modulate soil physical and chemical properties remain unclear.

Estimating Leaf Nitrogen Status of Strawberry by Using Chlorophyll Meter Reading

Journal of Biological Sciences, 2006
Measurement of leaf N through chlorophyll meter reading is of high importance to monitor leaf N status of plant throughout growing season. In present study, five short-day strawberry (Fragaria x ananassa Duch) cultivars including Sweet Charlie, Redlans Hope, Kabarla, Festival and Camarosa, were grown in 2003-2004 growing season to investigate the ...

Moderate Biochar–Compost Mixture Is More Effective in Improving Biomass, Nutrient Fluxes, and Photosynthetic Outputs for Sustainable Land Restoration and Soil Fertility

Land Degradation &Development, EarlyView.
ABSTRACT Soil nutrient depletion severely constrains crop productivity in degraded and saline environments. Strategies such as biochar–compost integration could be useful for sustainable agriculture and land restoration on a global scale. This study evaluated the effects of biochar (1% Bc), compost (1% Co), and their blends (0.5% Bc + 0.5% Co and 1% Bc

The Use of Chlorophyll Meters to Assess Crop N Status and Derivation of Sufficiency Values for Sweet Pepper

Sensors, 2019
Chlorophyll meters are promising tools for improving the nitrogen (N) management of vegetable crops. To facilitate on-farm use of these meters, sufficiency values that identify deficient and sufficient crop N status are required.

Higher NO3−‐N Levels Under Mulberry (Morus alba L.) Planting Enhanced CAZyme Abundance, Increasing Soil Carbon Stability

Land Degradation &Development, EarlyView.
ABSTRACT Afforestation is widely advocated for boosting carbon (C) sequestration. However, the stability of soil C pools in economically and culturally significant mulberry plantations remains poorly understood. The soil organic C (SOC) contents in different aggregates and the oxidizable OC fractions were measured.

Statistical filtering to aid in the sorting of phytoplankton: The effects of image library size and phytoplankton shape

Limnology and Oceanography: Methods, EarlyView.
Abstract The demand for efficient image sorting methods has increased due to technological advancements that enable more intensive phytoplankton monitoring. Both statistical and machine learning algorithms can misidentify algal taxa in taxonomically diverse samples, in which phytoplankton morphology and image traits can vary.
