Abstract

The present field experiment was carried out at Qaragol research station in Sulaimani governorate, Iraqi Kurdistan region which lies between (45o 37- 18" E east longitude, and 35o 21- 30" N north latitude) and is 552 m above sea level during spring growing season from 25/2/2014 to 3/6/2014 to study the effect of adding different poultry and cattle manure rates on vegetative growth characters and yield of Potato (Solanum tuberosum), cv. Sante. Ten-treatments were used in a randomized complete block design, in 30 experimental units with three replications as follow: [(control), (10, 20, 30-ton cattle/ha), (5, 10, 15-ton poultry/ha), and (10 + 5, 20 + 10, and 30 + 15-ton cattle + poultry/ha, respectively)]. Results showed that plants treated with (30-ton cattle/ha) had a significant increase in leaf area/plant and leaf area index (990.973 cm2, and 0.644 m2/m2) after 75 days after planting, plant length (18.850 cm) after 90 days of planting, tuber number/plant (6.050), tuber wt./ tuber (113.080 gm), tuber weight/plot (6.027 kg), and tuber yield (30.437 ton/ha), which was superior significantly to all other treatments respectively. Also, results showed that potassium and nitrogen content in leaves was ranged from (57.600 to 98.867, and 32.247 to 35.000 (gm kg-1), respectively. It can be concluded that the use of cattle manure (30 ton /ha) alone gave better results for almost the treatments in the present study.

Key words: Potato, Cattle Manure, Poultry Manure, Potato Yield, Days after Planting
