Abstract:
The experiments were carried out under AICRP on Medicinal and Aromatic Plant at College of Horticulture, Mandsaur under Rajmata Vijayaraje Scindia Krishi Vishwa Vidyalaya, Gwalior (M.P.) during the rabi season of 2019-20, 2020-21 and 2021-22. The treatments consisting four levels of potassium (0, 10, 20 and 30 kg K₂O ha^-1) in main plot and three levels of zinc (0, 10 and 20 kg Zn ha^-1) in sub-plot were laid out in split plot design replicated thrice with cv. Jawahar Isabgol 4. Results revealed that, the maximum plant height was recorded in K₄-30 kg K₂O ha^-1 (32.30, 33.00, 31.00 & mean 32.10 cm) while, number of tillers (4.10, 4.13, 4.00 & mean 4.08), spike length (3.80, 3.70, 3.50 & mean 3.67 cm) and seed yield (13.67, 13.67, 12.50 & mean yield 13.28 q ha^-1) were found in K₃-20 kg K₂O ha^-1 during 2019-20, 2020-21, 2021-22 and mean, respectively. Similarly, Zn₃-20 kg Zn ha^-1 had maximum plant height (30.70, 30.75, 29.50 & mean 30.32 cm) but number of tillers (4.00, 3.90, 3.80 & mean 3.90), length of spikes (3.55, 3.45, 3.36 7 & mean 3.45 cm) and seed yield (12.60, 12.25, 11.15 & mean yield 12.00 q ha^-1) were found with the application of Zn₂-10 kg Zn ha^-1 during 2019-20, 2020-21, 2021-22 and mean, respectively. Thus, it is concluded that 20 kg K₂O ha^-1 and 10 kg Zn ha^-1 performed best under the experiment.
