Abstract
The study explored the influence of different rates of sulfur and iron application on pea plants (Pisum sativum). An experiment was carried out on the farm of the National Research Centre of Research and Production in Nubaria district, Behira Governorate (Egypt) during the consecutive winter seasons of 2019/2020 and 2020/2021. Sulfur micronized was applied in varying quantities (Zero, 40, 80 and 120 kg fed-1) during soil preparation, while chelated iron was sprayed on the plants at concentrations of Zero, 50, 100 and 150 ppm on days 30 and 45 after planting. The data collected revealed that both sulfur and iron application had significant positive effects on chlorophyll content, plant biomass production, yield, and Macronutrient, calcium (Ca) content as well as micronutrients in both shoots and pods. Moreover, the nutritional quality of the pods, expressed in terms of protein and carbohydrate content, showed a favorable response to these treatments. The interaction between the two nutrients (sulphur at 80 kg fed-1 with the foliar spray at 150 ppm Fe) also had a significant impact on the growth and production of the pea plants followed by the interaction between sulphur at 80 kg fed with the foliar spray at 100 ppm Fe . Specifically, the plants treated with sulfur and iron displayed higher chlorophyll content, suggesting a more efficient photosynthetic process. Furthermore, these plants exhibited greater biomass and a higher number and weight of pods compared to the control group. The effects of applying both nutrients appeared to be cumulative.
