Determining the water productivity and irrigation water of sugar beet
under pressurized and surface irrigation methods in Torbat Heydariyeh
region
- Abstract: The purpose of this study was to measure the amount of water use, yield and water productivity of sugar beet under farmers management in Torbat Heydarieh region and the comparison of water use with impure water requirement of sugar beet in this region. The fields were selected with the help of experts in management and centers of agricultural in such a way that they represent the whole of sugar beet farms in region. Basic information including geographical characteristics and coordinates of fields, soil texture, electrical conductivity of irrigation water and soil saturated extract were determined. The date of planting, harvest date, growth period, sugar beet cultivar, average water depth per irrigation, total number of irrigation times performed, total volume of water use and leaching requirement was measured, calculated or obtained from farmers. The results showed that the average amount of water used in sugar beet fields in surface (furrow), sprinkler and drip irrigation methods was equal to 11468, 10054 and 10353 m3/ha, respectively. The lowest yield was 29500 kg/ha and the highest was 70000 kg/ha.The lowest water productivity was 3.21 kg/m3 and the highest was 7.01 kg/m3 and both values were obtained in surface irrigation method. The average water productivity in surface (furrow) irrigation methods was 4.19 kg/m3 and in sprinkler and drip irrigation methods were 6.30 and 6.23 kg/m3, respectively. By changing the irrigation method from surface to sprinkler and drip, water productivity has increased by 50.36 and 48.69%, respectively. According to the results of this study, the use of pressurized irrigation in sugar beet cultivation is recommended and farmers should use the irrigation system based on the design booklet and farm irrigation planning should be exactly what is recommended in the booklet.
Optimal spray water volume for the application of triflusulfuron-methyl
against redroot pigweed
- Abstract: Selecting the proper spray water volume is a method to optimize the herbicide efficacy but its effect on the efficacy of triflusulfuron-methyl is not clear. Therefore, in an experiment in the Research Greenhouse of Bu-Ali Sina University in the summer of 2017, six doses of triflusulfuron-methyl (Safary®) (0, 1.125, 2.25, 4.5, 9, and 18 g a.i. ha-1) were sprayed with ten spray water volumes (60, 80, 120, 160, 200, 240, 320, 400, 480, and 640 L water ha-1 which were obtained using a standard fan nozzle at sizes of 1100075, 11001, 110015, 11002, 110025, 11003, 11004, 11005, 11006 and 11008, respectively) on redroot pigweed at 1-, 2- and 3-leaf stages. In a field experiment, triflusulfuron-methyl at 18 g a.i. ha-1 was sprayed with the ten above-mentioned spray water volumes on redroot pigweed at the 2 to 3-leaf stage. In the one-leaf stage, the minimum (2.51 g a.i. ha-1) and maximum (2.51 g a.i. ha-1) dose of triflusulfuron-methyl required for 50% desiccation (ED50) with nozzle sizes of 1100075 and 11008 were obtained. In the two-leaf stage, the minimum and maximum values of ED50 with nozzle sizes of 1100075 and 11008 were equal to 2.98 and 12.16 g a.i. ha-1, respectively. In the three-leaf stage, the lowest ED50 values were obtained with nozzle sizes of 1100075 and 11001 equaling to 3.86 and 3.37 g a.i. ha-1, respectively. But the highest ED50 values was obtained with nozzle sizes of 11004, 11005, 11006 and 11008 equaling to 8.51, 8.70, 9.62 and 9.54 g a.i. ha-1, respectively. Overall, the results of the field experiment were similar to the greenhouse experiment and showed that less spray volume was needed to better control redroot pigweed with triflusulfuron-methyl; namely, the smaller, more concentrated droplets, the more efficacy of triflusulfuron-methyl against redroot pigweed.
