In order to investigate the possibility of Fennel autumnal sowing in Mashhad condition, 2 sets of experiments were conducted in Agricultural College, Ferdowsi University of Mashhad in 2003-2005. This experiment was performed in the manner of Split Blocks based on completely randomized Blocks with three replications. Treatments were two fennel ecotypes (Khorasan and Kerman) and three planting dates (October, December and March). Fennel seeds only were planted in 2003 and in next year, plants were grown of remains parts of stem in surface of soil. Results showed in end of first years, number of remain plant in March planting dates, three times of October planting dates. In second years, number of remain plant in March planting dates 6.5 and 2.7 times October and December planting dates, respectively. Number of remain plant between Khorasan and Kerman ecotypes were not significantly different in two years. However, effects of planting date and ecotype on dry matter and number of primary and secondary branches were not significant but plant of October planting dates superior to the plant of December and March planting dates. Number of umbel without seed in October planting dates was 3.4 and 8.8 times of December and March planting dates. In spite of weight of seed in October planting dates highest than December and March planting dates, effect of planting dates on weight of seed in plant was not significant. In first year highest and lowest yield were obtained in October (68.7 gr/m2) and March (20.5 g/m2) planting dates. But in second year maximum and minimum of yield were obtained in March and October planting dates with 45.3 and 14.2 g/m2, respectively.

In order to understand the effects of different organic and chemical fertilizer on stigma yield, corm characterstics and leaf dry matter yield (as a forage) of saffron (Crocus sativus L.), an experiment was conducted in the Research Station of Faculty of Agriculture, Ferdowsi University of Mashhad, Iran, in 2005-2009; as a Randomized Complete Block Design with 12 treatments and three replications. Experimental treatments included of: different levels of chemical fertilizers (250 kg Triple Superphosphate + 50 kg Urea/ha; 250 kg Triple Superphosphate +100 kg Urea/ha; 250 kg Triple Superphosphate + 300 kg Urea/ha), cow manure (20, 40 and 60 t/ha), sheep manure (20, 30 and 40 t/ha) and hen manure (5, 10 and 15 t/ha). Results showed that the highest fresh flower (315 kg/ha) and dry stigma yield (3.8 kg/ha) were obtained from chemical fertilizer (300-250 kg/ha Urea- Triple Superphosphate) and the highest dry forage yield (3410 kg/ha) and the highest mother and replacement corm per clump were obtained in sheep manure (40 t/ha). However, the highest corm weight per clump (119 g), average corm diameter (1.6 cm) and average number of bud per corm (6.5) were observed in 300 kg/ha Urea, the maximum average weight of corm (2.4 g) and total number of bud per clump (410) were obtained in 100 kg/ha Urea and 30 t/ha sheep manure, respectively. Most of growth indices and yield of saffron were improved by increasing in levels of sheep manure and chemical fertilizer but most of that charachteristics had a decreasing trend by increasing in levels of cow and hen manure. Generally, the highest amounts of most studied indices were obtained in chemical fertilizer and sheep manure and the lowest amounts of those studied indices were observed in hen manure.
