This study aimed to investigate anaerobic co-digestion of palm oil mill effluent (POME) with cassava peels (CP) and cabbage waste (CW) for biomethane production. The digestion (AD) in 10L capacity bioreactors loaded separately three different ratios (3L/ 520g, 3L/ 600g 680g) POME/CP, POME/CW POME only (control) was operated under ambient temperature (25 - 36⁰C) pH range 6.5 8.5 45 days. Standar...

Description of the subject. Phenolic compounds are very important to antioxidant capacity plant species. and hence commonly measured in laboratory using indirect methods that involve several stages chemicals. Objectives. This study aims identify species with high content phenolic measure these parameters leaves fruit near-infrared spectroscopy (NIRS). Method. A total 68 samples different variet...

Suitable rootstock enhances apple tree resilience. In 2021, we studied “Buckeye Gala” ( Malus domestica var. Buckeye Gala") on nine rootstocks with contrasting vigor in NS and BC, Canada. Rootstock effects vigor, yield, midday stem water potential were significant BC. After sustained heat events, the large-dwarfing Geneva 935, 4814, 969 had lower ratio of sunburn fruits, resulting higher projec...

two-spotted spider mite, tetranychus urticae koch (acari: tetranychidae), is one of the most injurious pests of fruits, vegetables and ornamental plants worldwide, both outdoor and indoors. currently the main method of control of this pest is through application of pesticides which is mostly accompanied by the resistance of the pest against pesticide(s). the resurgence of resistant mite populat...

In this study, we used apple tree (Malus domestica Borkh.) cv. Rubin grafts on dwarfing P60 rootstock. Our planting scheme was single rows with 1.25 m between trees and 3.5 rows. The aim of study to determine the impact canopy training treatments, as a stress factor, metabolic response obtain key information how improve physiological behavior management growth development trees. results indicat...

An anaerobic digestion of palm oil mill effluent (POME) for production of biogas was carried out at pilot scale under thermophilic condition. The objective of this research is to maintain short hydraulic retention time (HRT) and high degradation of the POME to biogas by applying recycle sludge. Fresh POME from PTPN IV without further treatment was used as feed. The fermentation process occurred...

The intention of this study was to compare the different parts Tunisian Ferula communis via their fatty acids, essential oils and phenolic compounds. Results showed that lipid fraction fruits leaves characterized by predominance oleic acid. Erucic linoleic acids were most abundant in stems while palmitic flowers. F. defined four chemotypes, namely isoshyobunone/6-tert-butyl-4-methylcoumarin ste...
