Effect of some pre-harvest treatments on onion seeds production under sandy soil conditions

Abstract

This study was conducted at the Agricultural Experiment Station of the Faculty of Agriculture, Cairo University, Wady Al-Natron farm, Egypt, during winter seasons of 2008/2009 and 2009/2010 to investigate the effect of spray with 12 commercial compounds and untreated treatment (spray with water) on onion seeds production and quality under sandy soils conditions. One commercial onion cultivar was selected for this study viz., Giza 20. the spray with union feer, union Mn, boron, elgae 600 and amino x had the higher inflorence diameter. While the foliar application of union Mn, shams K, boron, magnesium, amica and shetocare had the highest flower stalks length (cm). The highest number of seed stem/plant was recorded with the foliar application with union feer, shams K, and shetocare. The foliar application with union Zn, union feer, shams K, Magnisum, caboron, hummer and amino x had the highest seed yield. The highest germination percentage was recorded with the spray with boron, union feer, union Mn shams K.
