The effect of adding sulfur at different levels in the growth of Zea mays in Al-Qadisiyah Province

الملخص

Zea mays is ranked second in the world after wheat in terms of cultivated area, which may reach about 166 million hectares, while it is ranked first in terms of production from the total global grain production. The aim of study was the effect of four different levels of sulfur at different application times on the growth and yield of plants. The results showed that increasing the levels of sulfur fertilizer in the soil led to an increase in some growth and yield characteristics, and that the highest average leaf area in was achieved in the treatment of adding sulfur at the level of 1500 kg ha^-1 in the experiment,. The same treatment also achieved the highest average plant height, which compared to the control level. The treatment of adding sulfur at the level of 1500 kg ha^-1 achieved the highest average number of grains per ear, compared to the control. The same treatment achieved the highest average weight of 500 grains. The highest average leaf chlorophyll content, compared to the control treatment. The same treatment achieved the highest average stem diameter, compared to the control treatment.
