Abstract

In order to study the effect of bio-fertilizers, Planting method and superabsorbent polymer on quantitative yield of Saffron under rainfed conditions, a factorial experiment based on randomized complete block design with three replications was conducted at the Agricultural Research Station of Khorramabad, Iran during 2015-2016 growing seasons. In this study, Nitroxin bio-fertilizer (consumption 5 Lit. ha-1 and non-consumption), Stockosorb superabsorbent polymer (consumption 240 kg. ha-1 and non-consumption) and Planting method (streaking and cluster) was tested. The results showed that triple interactions was significant for number of corm. m-2 in the first and second year and combined treatment including non-Nitroxin in cluster culture method using superabsorbent with 80. 67 corm. m-2 for the first year and with 183. 67 corm. m-2 for the second year was the superior treatment. The results showed significant differences for number of produced flowers and for fresh and dry weight of stigma in both years. In the first year, treatment including cluster method cultivation, consumption of superabsorbent and no consumption of Nitroxin was superior; while in the second year, the superior treatment was use of superabsorbent, Nitroxin and cluster method. For stigma dry weight of Saffron, triple interactions was significant and in the first year, cluster method and consumption of superabsorbent and no usage of Nitroxin was superior (with 0. 6 kg. ha-1), and in the second year, use of Nitroxin and superabsorbent and cluster method was superior (with 0. 719 kg. ha-1). In general, the results of the present study in dry-farming conditions over the two years, the cluster cultivation method with usage of superabsorbent and Nitroxin could be recommended. The reasons for this recommendation and introduction of the mentioned methods are the dry climate conditions in the area of study and reduction in consumption of chemical fertilizers for development of sustainable agriculture.
