Abstract:
Field experiment was carried out during 2018 at Al-Ghab, Sarmiyah village, to study the effect of potassium fertilization rates (0, 70, 110,and 150) k.g/ha and Methods of adding yeast (without adding, wrapping seeds, spraying on plants, and adding with irrigation water)and the interaction between some physiological and chemical indicators, like (Number of leaves, leaf weight, leaf area, protein percentage, oil percentage(, The experiment was designed by split block design, with three replications, result showed that adding. Potassium fertilization and yeast methods led to a significant increment in the pervious traits compared with the control (without adding any treatment). The largest values for the number of leaves and leaf weight were found at the interaction between potassium fertilization rate 110 kg (K2O) hectare and adding bread yeast by spraying on the plant by 85 than the control, while the interaction between potassium rate 150 kg (K2O) / hectare and the spray method achieved ahigher surface area average compared with the control by 3945 cm2 , which indicates the importance of the interaction between these two factors. The addition of potassium fertilization at the rate of 150 kg (K2O)/ha gave the highest percentage of oil in the seeds 51.95%, while the highest percentage of protein in the seeds was 31.65% at the rate of 70 kg (K2O)/ha, while the method of adding baking yeast by spraying with irrigation water gave the highest values. in the percentage of oil in the seeds, while the combined reaction between the rate of 150 kg (K2O) / ha with the method of adding baking yeast with irrigation water gave higher values in the percentage of oil in the seeds 53.82%.
Key words: Peanuts, potassium fertilization, bread yeast, number and weight of leaves, leaf aria, oil, protein
