DEVELOPMENT AND EVALUATION OF A FLAME UNIT FOR WEED CONTROL IN NEWLY SOILS.
The present study aims to reduce the use of herbicides for weed control. solving the problem of decrease agricultural manual operators in industry - city such as Domiatta Governorate and decrease the cost of weed control in newly reclaimed soils. So. an attempt was carried to develop a flame unit in a trail to kill seeds, rhizomes. bulbs and tubers of weeds which lie dormant in the soil directly after secondary tillage and before crops planting. The flame unit was tested under different forward speeds, burners spacing, height of burners above the soil surface and arranged the bumers in one and two rows. The weed control cost was 22.9 LElFed at 40 cm burners spacing. However when decreasing burners spacing to 30 and 20 cm the weed control cost increasing to 28.1 and 47.6 LE/Fed. respectively at 1.8 km/h forward speed, 25 cm flame height when burners arranged in two rows for both rice and corn fields. It would be conculded that the mechanical weed control costs at the previous parameters with burners spacing of 40,30 and 20 cm were 14.3, 17.6 and 29.8 % from manual control cost. Whilest. the flaming efficiency increased with decreasing burners spacing due to the intensity of flaming into soil surface.
