Abstract
This research aimed to study the impact of both; sowing date and variety in controlling maize stem-borers and its influence on the production as well as the total cost, revenue, and net profit of the cultivation of maize crop. This study was carried out at Al-Meriayah Research Station in Deir Ez-Zor governorate during 2010 and 2011. Maize varieties and hybrids i.e. Ghouta82, Ghouta1, Basel1 and Basel2 were cultivated in the intensive planting time, every ten days starting on the first of June. The results showed that the total costs increased with the delay of planting date with an average about 1149.2, 1473.04 and 1501.17 dollar/ha in the first, second and third sowing dates respectively in 2011. The maximum and minimum average of costs were about 1384.1 and 1183.41 dollar/ha for Basel1 hybrid and Ghouta82 variety, respectively in 2010. The total revenue was positively correlated with the date of sowing. The lowest total revenue was detected in Gouta82, but Bessel1 achieved the highest value. As a result, Basel1 hybrid achieved the highest net profit (542.97 dollar/ha) in 2010, as well as the third date of sowing (21st July) gave the highest net profit (679.4 dollar/ha) in 2011.
