Abstract

To study the effects of irrigation regimes and plant densities on yield and agronomic characteristics of Isabgol (Plantago ovata), a field experiment was conducted at Research Station, College of Agriculture, Ferdowsi University of Mashhad, during the years 2000 and 2001. A split plot design based on randomized complete block design with three replications was used. The treatments comprised four irrigation regimes, 7, 14, 21 and 28 interval days allocated in the main plots and four plant densities, 8, 10, 14 and 20 in the first year and 20, 60, 100 and 140 plant/m2 in the second year allocated in sub plots. The characteristics that were studied consist of spike length, plant height, number of spikes per plant, number of seeds per spike, 1000 grains weight and grain yield. Results showed that the irrigation regimes in each of 2 years had significant effects on plant height, number of spikes per plant and grain yield. The seven irrigation interval days had the highest grain yield. Plant density had no significant effects on spike length, plant height and 1000 grains weight in 2 years. The effect of plant density on number of grains per spike was significant only in the first year of study. In the first year, plant density had no significant effect on number of spikes per plant, but in the second year with increasing in the densities, the number of spikes decreased. The lowest number of spikes was shown in the highest density (140 plants/m2). With increasing plant density grain yield were increased significantly in both years. The highest grain yield was obtained at the highest density (140 plants/m2).
