Biofilms currently represent the most prevalent bacterial lifestyle, enabling them to resist environmental stress and antibacterial drugs. Natural antibacterial agents could be a safe solution for controlling bacterial biofilms in food industries without affecting human health and environmental safety. A methanolic extract of Azadirachta indica (ne...

In this study, silver nanoparticles were synthesized using lemon leaf extract, which served as both a reducing and stabilizing agent. The synthesis process proved to be rapid, cost-effective, and environmentally friendly. The effect of the mixing ratio of the reactants was investigated. Optimal yield, approximately 70%, was achieved at 60°C with a...

Fresh-cut flowers are considered to be one of the most delicate and challenging commercial crops. It is important to take into consideration how to minimize loss during storage and transportation when preserving cut flowers. Many impinging (bad effect) forces can interact to shorten the flowers' vase life. In the flower industry, effective methods...

Nanotechnology is a potential solution for increasing the value of the agricultural products and environmental problems. In this work the phytotoxicity and stimulatory effects of graphite and silica nanoparticles on seed sprouting, yield characteristics and chemical composition of Nigella sativa L were studied. Seeds were soaked in six concentratio...

There is an urgent need to overcome seed dormancy especially in some multi-benefit tree like baobab, which can be successfully cultivated in Southern Egypt, in order to improve their regeneration. Therefore, this study was carried out to investigate the effects of some pre-germination treatments i.e., soaking in tap water, boiling water or sulphuri...

Tparticularly in agriculture application. In this effort HERE has been a rising demand for nanotechnology-based products in recent years, , the phytotoxicity and stimulatory effects of graphite and silica nanoparticles (NPs) on seed germination, yield characteristics, chemical conformation and root anatomical characteristics of (Pimpinella anisum L...

Afield experiment was conducted during 2016 and 2017 in the Research Farm of Sakha Agricultural Research Station, Kafr El-Sheikh Governorate, Egypt to evaluate the mutual effect of irrigation scheduling and silica nanoparticles on Ocimum basilicum L. vegetative growth, yield, chemical composition and some water relations. Irrigation scheduling trea...

Jerusalem artichoke has gained popularity as a new vegetable appearing in markets over the past few years. To improve the quality and storability of tubers, two types of packages (perforate high density polyethylene HDPE and polypropylene PP) and two kinds of essential oil (spearmint and black cumin oils comparing untreated, control) were examined...

Salinity is one of the extremely serious abiotic stresses for plants, affecting other subsequent consequences such as oxidative stress, which finally leads to cell death. A pot experiment was performed during 2014 / 2015 and 2015/ 2016 at Sakha Agricultural Research Station, to elucidate the alleviation of salinity effects by spraying gibberellic a...

Experiment was conducted at Sakha Horticulture Research Station, Kafr El-Sheikh Governorate, Egypt, during the two successive seasons of 2014/2015 and 2015/2016 to study the effect of foliar spray with kinetin and zinc on Clivia miniata, L. plant for improving growth performance and raising new formed rhizomes. Kinetin and zinc were sprayed after t...

Water considers the most important component of life, it is rapidly becoming a critically short commodity for humans and crop production. Drought is one of the major a biotic stresses in agriculture worldwide. In order to study the effect of water stress (skipping one irrigation at vegetative, flowering and fruits formation growth stages) in compar...

Evidences stated that microclimate causes noticeable effects on life cycle, consumptive use of water and planting time of the plant species. So, two field experiments were established at Sakha Agricultural Research Station during 2013 and 2014 growing seasons in order to evaluate the effect of microclimate on planting date as well as the influence...

This experiment was carried out at Sakha Agricultural Research Station from June 2011 to May 2012 to study the problem of reduction of cumin (Cuminum cyminum) seed germination. Cumin seeds were obtained from different sources for conducting the study. Several microbial species including sixteen fungal taxa, some yeasts and bacteria, were isolated f...

Two field experiments was established at Sakha Agricultural Research Station during the two seasons of 2008/2009 and 2009/2010 to evaluate the effect of planting spaces and active dry yeast on the growth ,yield and oil components of Melissa officinalis ,L. Three planting spaces (30, 40 and 50 cm) and four applications of active dry yeast (control,...
