Inoculating rice plants by plant growth promoting rhizobacteria (PGPR) may be used as a
practical and eco-friendly approach to sustain the growth and yield of drought stressed rice …

Portable, non-destructive chlorophyll meters could be a valuable tool for forest managers
and researchers. The ability of such meters to assess both chlorophyll and nitrogen content …

Various indices established on a portable SPAD-502 meter can serve as indicators of the
nitrogen status of a plant. We compared di-positional SPAD readings and indices with …

Background Premature leaf senescence induced by external stress conditions, eg drought
stress, is a main factor for yield losses in barley. Research in drought stress tolerance has …

Newly developed non-destructive fluorescence-based indices were used to evaluate
nitrogen (N) fertilization rates and leaf nitrogen content in Paspalum vaginatum and Zoysia …

Soil is a valuable resource with a key productive role in agriculture. Abiotic stress is the most
harmful factor concerning the growth and productivity of crops worldwide. Physiologically …

Biochar improves soil quality. However, most biochar research has focused on aerobic soil
conditions. The objective of this research was to evaluate the agronomic benefits of applying …

Prunus africana is an endangered medicinal plant and hence new propagation methods are
urgently required to increase its populations. Unfortunately, propagation through seeds is …

Key message The soil plant analysis development (SPAD) meter proved effective at
estimating leaf Chl content of native and non-native temperate deciduous shrubs. However …

Green-leaved foliage plants are valued for their leaf forms and sizes but mainly for their foliar
greenness. Evaluation of the quality of these plants has been based primarily on visual …
