Abstract
An experiment was carred out on the farm of the Dept. of Field Crop Sci./College of Agric./University of Baghdad . This was on two cultivars of tobacco ; Habbana Legaro for cigar and SH for cigarettes . A nursery for transplants was prepared in 2009 and 2010 , then transplants were transferred to plastic house in the field . Spacing were 80×31 cm. In the first year , fertilizers of N,P and K were used , and also ,silica sand , manure , and ash. In the second year , the experiment focused on soil texture mentioned treatments only. At flowering , readings were taken on plant height , leaf area , then leaves were dried and weighed . Combustion test was undertaken on leaves. Results obtained showed that ash treatment plants gave higher leaf area of Habbana cultivar (2.89 m²) , then treatments of manure and sand (2.24 & 1.91 m² ). Habbana cultivar outyielded SH cultivar in all traits studied . Plants of sand treatment gave higher leaf dry weight (164.3 g) , while manure and ash treatments were next (127.5 g and 112.5 g) . Sand treatment plant leaves showed higher combustion (72.5%) for Habbana , while ash treatment was next to it (67.0%). It was concluded that applying more than 80-100 kg/ha of N , P , and K will cause poor combustion. The results showed that higher doses of these elements ; especially N and S will give poor combustion. That , for these two elements cause higher protein which cause poor combustion. Applying sand to tobacco fields is quite recommended.
