Abstract: The periodical observations on chlorophyll a, chlorophyll b and total chlorophyll concentration recorded at various dates under varied fertility levels. It was noted that the application of nitrogen over no nitrogen (control) enhanced the chlorophyll a content at all the growth stages. However chlorophyll b concentration was relatively lower than chlorophyll a concentration. Each additional soil and foliar application of nutrient from F₁ to F₆ improved the chlorophyll content of soybean. The higher chlorophyll synthesis in treatment F₆ followed by F₅ due to additional foliar sprays of potash and boron. The quality parameters of soybean viz., protein and oil content significantly influenced by soil and foliar application of nutrients and growth regulators. Treatment F₆ (RDF + Zn + foliar K, B and GR) recorded numerical higher protein and oil content which was found at par with all other treatments.
