Increasing onion yield and improving bulb quality are essential aims for growers to fulfill the requirements of the market and the consumers. Two field experiments were carried out during two successive seasons; 2011/2012 and 2012/2013 at the experimental station of National Research Centre, Beheira Governorate (North of Egypt) to find out the influence of some bio-stimulants i.e., yeast extrac...

In the in-situ remediation of ammonium (NH4+) in groundwater by a sequential reactive barrier filled with zeolite, it is of great importance to understand the mechanisms of NH4+ sorption to zeolite. In this study, the effect of dissolved natural organic matter on NH4+ sorption to natural Chinese clinoptilolite was studied by batch experiments taking humic acid (HA) as a model substance. The sur...

A hybrid Svyatogor F1 of Dutch breeding was grown in a winter greenhouse for three turns. Studies have shown that pre-sowing seed soaking treatment and foliar top dressing plants with potassium humate did not affect germination, but positively affected plant growth, except lithium carbon dioxide. For PABA, the leaf area increased, while it decreased. Micro fertilizers, lithium, had positive eff...

Humate substances (HSs) are raw materials very easy to obtain and naturally occurring organic molecules found in soil due the humification of dead components. Traditionally used as conventional medicine China India fertilizer agriculture. Humic acids widely utilized feed additives could enhance ruminant performance. The effect humic acid on intake depends level supplementation, a source, experi...
