- Isabgol (Plantago ovata) is a valuable medicinal crop. The study evaluated the growth and yield performance of Ispaghol (Plantago ovata) in the dry zone of Bahawalpur under various planting dates in order to determine the ideal sowing time. Using germplasm from five accessions, five different sowing timings (T1: October 15th, T2: November 1st, T3: November 15th, T4: December 1st, and T5: December 15th) were evaluated. The experiment used a randomized complete block design with three replications and it was carried out throughout the 2019–2021 rabi season. At essential growth phases, a number of agronomic characteristics were observed. According to the results, The maximum grain yield (1653 kg/ha) and 1000 grain weight (4.16 g) were obtained from sowing on November 1st (T2) along with the highest harvest index (56.3%). On the other hand, out of all the accessions, the planting date of December 15th (T5) yielded the lowest grain yield (918 kg/ha). T2 outperformed the other sowing periods in terms of growth performance across a range of characteristics; T1, T3, and T4 came next. T5 displayed the fewest granules per plant. In general, the best date to seed ispaghol in the research region was found to be November 1. The purpose of this study was to determine the optimal sowing time for improving ispaghol (Plantago ovata) growth and yield performance.
