The study showed that application of different doses of inorganic nutrients had considerable influence on growth, yield and downy mildew interaction in isabgol (Plantago ovata). It included three levels of nitrogen (0, 30, 60 kg N ha–1), two levels of phosphorous (0, 30 kg P ha–1) and two levels of potash (0, 40 kg K ha–1) for 2 consecutive years. The highest N supply (60 kg ha–1) caused more than 65% increase in disease severity compared with the control. However, application of 40 kg K ha–1 reduced percent disease index (PDI) by more than 10% compared with 0 kg K …
