Abstract Two experiments were carried out at the Experimental Farm of the Faculty of Agriculture, Sohag University during 2010/2011 and 2011/2012 winter seasons, where the soil is newly reclaimed. The present investigation was carried out to study the response of foliar micronutrients application (without, once,twice and three times), three onion cultivars , different potassium fertilization levels (0,50,100,150 kg K2O/fed.), and post-harvest storage potential under Sohag conditions. The findings of the investigation have been summarized in this chapter. First experiment : a. Micronutrients : The most field studied characters plant height (cm), number of leaves/plant, bulbing ratio, neck diameter (cm), bulb diameter (cm) and total yield (ton/fed.) were affected significantly by micronutrients foliar application. Where, the highest value of plant height (cm), nomber of leaves/plant, neck diameter (cm), bulb diameter (cm) bulbing ratio, and total yield (ton/fed.) were obtained from three times foliar trace elements application in both seasons. b. Cultivars : The most field studied characters plant height (cm), number of leaves/plant, neck diameter (cm), bulb diameter (cm), bulbing ratio, and total yield (ton/fed.)were affected significantly by cultivars. where the data showed that Giza 20 cultivar was the tallest plants, gave the highest number of leaves per plant, the highest in neck diameter, produced the highest total bulb yield in both seasons. While, Shandaweel 1 cultivar was the earliest maturity in both seasons. |
