Weed control with flame technique in sunflower growing

The aim of this study is to determine the effects of flame application on five different weeds and on yield in sunflower cultivation. To determine these effects, a trial pattern consisting of a total of 10 subjects was created in a sunflower field with nine different application treatment and one control parcel. Six different flame applications were performed using two different LPG doses (75 kg/ha and 60 kg/ha) and three different flame application methods (over-the-desk, row-by-row, surface). In addition, in order to compare flame application and weed fight with tilling, three applications were made with 2 different doses (75 kg/ha and 60 kg/ha) flame application, as well as tilling and hoeing only. Weeds are marked as having 4 recurrences in three different stages of growth. Visual control rates were determined on the 1st, 7th, 14th days after the application to determine the rate at which weeds are affected by flame application. At the end of the 14th day, the root, trunk weight and length of marked weeds were measured. The effect of flame on weed was revealed by comparing the age and dry weight of the weeds dried in the 24-hour study machine. In order to examine the yield in sunflower production, the table diameter, height and product kg weight of the harvested sunflower were measured and the effect of flame and weed control on yield was measured. As a result, the highest efficiency (244.59 kg/da) was achieved in the integrated (T7) application of tilling and 60 kg/ha LPG dose. When we look at the effect of flammable application in the fight against weeds, the most effective results were obtained in the application of flame (T6) above 75 kg/ha row in all weeds in general.
