In search for sustainable agricultural methods for medicinal plants. A field experiment was conducted at the College Agronomy Farm, Anand Agricultural University, Anand, Gujarat during rabi season of 2013-14. The experiment consisted of eighteen treatment combinations comprised of three nitrogen levels (15, 30 and 45 Kg N ha?-1), three phosphorus levels (0, 15 and 30 Kg P ha?-1) and two potassium levels (0 and 30 Kg K ha?-1). The treatment N3 (45 kg N ha-1) recorded significantly the maximum seed and straw yields as well as plant height at harvest, no. of effective tiller plant-1, no. of effective spikelet plant-1 and test weight of 1000 seeds and significantly higher length of spike as compared to other nitrogen treatments i.e. N1 (15 kg N ha-1) and N2 (30 kg N ha-1). Significantly higher seed and straw yields as well as plant height at harvest and no. of effective spikes plant-1, while no. of tiller plant-1 showed the significantly higher - response by application of 30 kg P2O5 ha-1, other characters like length of spikes and test weight of 1000 seeds and swelling factor found to be non-significant response. The response on growth and yield attributing characters as well as seed and straw yields of isabgol were also found non-significant due to different potassium levels. On economical point of view when isabgol treated with 45 kg N ha-1, 30 kg P2O5 ha-1 and 30 kg K2O ha-1 noted higher net realization as compared to other treatment.
