Abstract:
For the agricultural season (2021-2020), an experiment was conducted in two soils in Nineveh Governorate, the first in Al-Hawi soil and the second in Al-Rashidiyah soil, to find out the effect of adding levels of sulfur and phosphorous, and their interaction, on the growth and quantitative and qualitative production of the bean plant. Three levels of sulfur (0, 2, 4 tons ha-1) and three levels of phosphorous (0, 80, 160 kg P. ha-1) was given to the experiment. The results indicated that the increased additions of sulfur and phosphate fertilizers at all levels added, whether individually or in combination, led to positive effects in improving most growth characteristics and quantitative and qualitative yield by increasing plant height cm, number of branches. plant-1, number of pods. plant-1 and number of seeds. plant-1 The seed yield (gm. plant-1), fertilization efficiency%, and protein content (mg. plant-1). The results showed that the interaction effects of both factors were higher to every element’s effect alone, as the plants receiving the greatest levels of both elements (sulfur 4 tons. ha-1 and phosphorous 160 kg. ha-1) improved in most of the parameters evaluated and in both soils. Al-Hawi soil showed a high response to the addition of sulfur and phosphorous at all levels, whether singly or overlapping in the studied traits compared to Al-Rashidiyah soil.
