In order to investigate the effects of foliar nutrition and planting distances on corm criteria of saffron (Crocus sativus L.) on sixth year farm, an experiment was conducted as complete randomized block design in a factorial arrangement with three replications under field condition in Research Station, College of Agriculture, Ferdowsi University of Mashhad in 2012 growing season. Treatments included four planting patterns of saffron (planting distances of 20×5, 20×10, 20×15 and 20×20 cm) and three levels of foliar nutrients application (0, 1.0% and 2.0% solutions per hectare (with 6% N, 2.5% P, 2.5% K, 2% Mg and Ca and 1% Fe, 0.05% Zn, 0.05% Cu and 0.05% Mn Chelates)). Foliar nutrients application was done in March 7th, 2012. In this experiment total number of corms, total weight of corms, total weight of corms without tunics, total weight of tunics, total number, average weight, average diameter and average number of buds of corms more than 8 g (large corms), between 4.01-8 g (medium corms) and lower than 4g (small corms) were studied. Results indicated that planting pattern had significant effects on number of corms, total weight of corms and number of large corms and medium corms of saffron. Foliar nutrients application had significant effects on number of large corms, medium corms and small corms of saffron. In addition, interaction effects of planting pattern×foliar nutrients application were significant on total weight of corms and the number of large corms. The highest number and the total weight of corms observed in 20×5 cm planting distances with 576 corms/m2 and 1875 g/m2, respectively. In foliar nutrition treatments the maximum number of large corms was obtained in 1.0% solutions (21.3 corms/m2). However, on planting distance of 20×20 cm, the highest number of large corms was stand in 2.0% solutions, the responding number of large corms of saffron to foliar nutrients application was decreased significantly by reducing corm planting density.
