The effects of different levels of applied wheat straw in different dates on saffron (Crocus sativus L.) daughter corms and flower initiation criteria in the second year

In order to investigate the effects of different levels of applied wheat straw as mulch in different dates on flower characteristics and corms behavior of Saffron (Crocus sativus L.) in the second year, a field experiment was conducted as factorial layout based on a randomized complete block design...

The experimental treatments were all combination of different levels of wheat straw as mulch (0, 2, 4, 6 and 8 t. ha-1) based on surface applied method in three different dates (June, August and October). The results showed that the applied wheat straw as mulch in different dates had significant effects on flower characteristics of saffron (flower number, fresh and dried flower and stigma+ style yields). Based on these results, applied wheat straw as mulch in October had highest effects on increasing flower number, fresh and dried flower yields (by 46, 61 and 65%, respectively). In addition, applied wheat straw as mulch had significant effects on number and yield of replacement corms. The applied straw as mulch in October increased yield of replacement corms with 12 g or higher weight and total corm yield of saffron by 104 and 103 %, respectively, as compared to control treatment.http://saffron.torbath.ac.ir/article_4811_1364d95726c5ffe883521030081e71a8.pdfFloweringSaffron cormsWheat mulch
