Olive seedlings growth as affected by humic and amino acids, macro and trace elements applications

Growth of Maize Seedlings as Affected by Glucokinin and Insulin

1. Solutions of glucokinin and insulin, particularly those from which the easily dialyzable substances had been removed, increased the growth of roots and tops of young maize seedlings, as shown by comparisons with untreated seedlings grown in distilled water. 2. Strong solutions of crude glucokinin or of crude insulin repressed growth. 3. Seedlings from which the tips of the primary roots had ...

Sunflower morphology and yield as affected by foliar applications of plant growth regulators

Plant height of sunflower is a major agronomic trait affecting crop performance in the field and its adaptation to mechanical harvest. Field experiments were conducted to study the effect of foliar application of paclobutrazol (PBZ) at 12.5 g ai/ha, mepiquat chloride (MPC) at 25.0 g ai/ha and chlormequat chloride (CCC) at 1,500 g ai/ha in single or double applications on sunflower plant mor...

Effect of Trace Elements on Growth of Aspergillus Niger with Amino Acids

A necessary preliminary to investigation of the effect of deficiencies in trace elements on the growth of Aspergillus niger Van Tiegh. with the amino acids is a study of the nutritive properties of these acids. Information in this respect is quite limited and difficult of interpretation because of differences in experimental conditions. Extensive tests, therefore, were made relative to the effe...

Evaluation of Quantitative and Qualitative Traits of Chickpea as Affected by Biofertilizer, Nitrogen, and Humic Acid in Dryland Condition

In order to evaluate biofertilizer, nitrogen and humic acid effect on quantitative and qualitative traits of chickpea (ILC 482 line) this research was carried out at the Agricultural Research Field of Kurdistan University, Sannadaj, Iran. A factorial experiment was conducted based on a randomized complete block design with three replications. Experimental treatments included three levels of lea...
