Abstract
An experiment was carried out with Black Isabgol (Plantago indica L) an annual herb cultivated recently as a medicinal plant at Directorate of Medicinal and Aromatic Plants Research (DMAPR) in India, aiming on the effect at different stages of growth under the influence of different sowing dates and spacings on growth, seed yield and seed swelling factor as a part of good agricultural practices (GAP). No detail morpho-physiological work has been carried out in this species including yield. Results revealed that growth and yield were significantly influenced by sowing dates and spacings. The best time for sowing of P. indica was found to be between 15-30th November and the suitable spacing was either 50 or 60 × 15 cm. Swelling factor was not influenced by these factors, however, a positive trend was observed towards suitable date of sowing and spacing. The finding was a step forward towards determining good agricultural practices (GAP) of P. indica, probably an alternative of P. ovata in future.
Key words: Plantago indica, Sowing date, spacing, growth, yield, swelling factor.
