In order to investigate the effect of planting density and maternal corm weight on some characteristics of daughter corms and agronomic characteristics of saffron (Crocus sativus L.) a field experiment was conducted at the Agricultural and Natural Resources Research Center of Mashhad. This experiment was carried out as a factorial split plot in time based on complete block design with three replications and 12 treatments during the years 2010-2014. The experimental factors were 3 levels of density (40, 80 and160 corm in m2) and 4 levels of mother corm weight (≤3, 3-6, 6-9 and 9-12 g per corm) as a main plot and time as a sub plot. The results showed that density, maternal corm weight and year had significant effects on daughter corm’s weight, but the effect of interaction density × corm weight and density × weight × year were not significant for the most characteristics. The mean comparison of interaction effect of density × weight for number of daughter corm showed that maternal corm weight (9-12 g) × planting density (160 m2) had the highest number for daughter corms (771 m2). Maternal corms with higher initial weight produced the highest number of corms in different corm classes. In addition, the results showed that maternal corm with lower initial weight produced heavy daughter corms compared to other maternal corm weight classes. Flower weight and stigma dry weight of saffron (m2) were increased by increasing planting density and maternal corm weight flower number. The highest dry stigma (0.65 g.m-2) yield was produced by maternal corm (9-12 g per corm) weight class.

In order to investigate the effects of first irrigation date and organic fertilizers on growth and yield characteristics of saffron, an experiment was conducted as a split-plot based on a randomized complete-block design with three replications, in Khaf city during growing season 2013-2014. Date of first irrigation treatment in three levels (15 September, 30 October and 15 November) was allocated as main plots and fertilizer treatment in five levels (control, humic acid at 5 and 40 liters per hectare, cow manure at 5 and 40 t.ha-1) was set as subplots. Analysis of variance showed that the date of first irrigation had a significant effect on all studied traits except for total fresh weight of corm and the average weight of corm of saffron. Effects of different organic fertilizer treatments on all studied traits were significant, except for corm number with 8 g (8.00) weight were obtained in first irrigation on 6th November. The first irrigation at 7th October was superior to the other irrigation treatments for corm number with
