Abstract

In order to study effect of foliar application of Zinc and Manganese on yield and quality of potato crop, an experiment was conducted at Aligoudarz Agriculture research station, Lorestan, Iran. The experiment was a randomized complete block design whit 4 replication. All combinations of 4 levels of both elements (including 0, 2, 4 and 8 ppt solution as sulfate compound ZnSO4, MnSO4), Which formed 16 different treatments, were distributed randomly in each block. Solutions were sprayed 10 days before and 20 days after flowering. Plants were harvested after ripened and plant characteristics including tuber weight, number of tuber per plant, tuber yield, percent of dry matter, specific weight, protein and starch percent on tuber were measured. Results showed that Zn and Mn application increased all plant characteristics relating to yield and quality of potato crop. These were tuber yield per plant, dry matter percentage, specific weight, protein and starch contents of the tuber. Application of Zn at 8 ppt increased yield to 34170 kg ha-1 which, was 25% higher compare with control, meanwhile application of Mn at 4 ppt level increased yield to 33866 kg ha-1 which was only 15% higher than control. However application of Mn at 8 ppt decreased both quality and yield of potato tuber compare with 2 and 4 ppt. maximum yield (38950 kg ha-1) was obtained at 8 ppt of Zn and 4 ppt of Mn foliar application. Fertilizers were significantly affected on elements percentage in tuber. Zinc increased Zn percentage and decrease phosphorus percentage in tuber. Manganese increased Mn percentage of tuber, but no significantly effected on Zn, P and K in tuber. Zinc and manganese Fertilizers together increased Zn and Mn percentage and decrease P percentage in tubers, that they no significant.
