The availability of orthophosphate (Pi) is a key determinant of crop productivity because its accessibility to plants is poor due to its conversion to unavailable forms. Weed's competition for this essential macronutrient further reduces its bio-availability. To compensate for the low Pi use efficiency and address the weed hazard, excess Pi fertilizers and herbicides are routinely applied, resu...

A greenhouse pot experiment was conducted to evaluate the effect of phosphorous (P) fertilizers application to an alkaline calcareous soil on the water use efficiency (WUE) of lettuce cultivar "robinson" of iceberg type. Head fresh and dry weights, total water applied and WUE were affected significantly by the P fertilizer type and rate. P fertilizers addition induced a significant enhancement ...

This research was performed to evaluate the effects of foliar application of nano-silicon (NSi), as a quasi-essential element, on yield, flower quality, vase life and infestation percentage of gerbera by greenhouse whitefly. Treatments were preharvest foliar application of different levels of NSi (0, 50 and100 mg/L) on gerbera 'Stanza' in a soilless system (to eliminate the effects of soil's Si...
