ABSTRACT: This study was conducted on 5-years-old grafted sweet lime trees as a factorial arrangement in randomized complete block design with 4 replicates. The first factor was ammonium sulfate (0, 250 and 500 g for every tree as soil application) and the second factor was iron sulfate (0, 5 and 10 mgL-1 as spraying in mid-June after June drop). In the harvest time were measured iron leaf; fruit volume; peel water percent; vitamin C and total acid in fruit juice and finally tree yield. Results showed that the treatments had significant effect on some characteristics including fruit volume; yield; vitamin C; total acid; peel water percent and iron leaf amount. In general, based on the results can be recommended application of 250 g of ammonium sulfate for every tree in soil and spraying 10 mgL-1 iron sulfate during June to improve the quantity and quality characteristics as well as increased yield of sweet lime in calcareous soil.
