Studying the effects of manure and zeolite on nitrogen uptake and utilization efficiency of saffron (Crocus sativus L.) under deficit irrigation conditions
A study was conducted in 2013-2014 at the Ferdowsi University of Mashhad farm in a split, split plot design based on a randomized complete block design with three replications. The irrigation treatments were considered at three levels (50, 75, and 100 percent of water requirement) as the main factor, the use of manure at three levels (9, 18, and 27 tons per hectare) as the secondary factor, and the use of zeolite at three levels (0, 3, and 6 tons per hectare) as the secondary factor. The results showed that in the irrigation treatment (100% water requirement), 27 tons/ha of manure and 6 tons/ha of zeolite, we witnessed an increase of 15 and 107%, respectively, in the maximum leaf area index and leaf dry weight compared to the treatment of 50% water requirement, 9 tons/ha of manure and without zeolite. The highest amount of stigma dry weight was obtained in the treatment of 100% water requirement and the treatment of 27 tons of manure and 6 tons/ha of zeolite with an increase of 30% compared to the treatment of 50% water requirement, 9 tons/ha of manure and without zeolite. In the conditions of full irrigation and 27 tons of manure and 6 tons/ha of zeolite, the number of corms with a weight of 5-7 and 7-9 grams increased by 30% and 47%, respectively, compared to the irrigation of 75%. Under conditions of complete irrigation of complete manure and complete zeolite, a 217% increase in nitrogen absorption efficiency was observed. Under conditions of complete irrigation of complete manure and complete zeolite, a 48% increase in nitrogen use efficiency was observed.
