Abstract: The article presents the results of the water requirement of Echinochloa frumentacea during 2012-2015 on light loamy soils, in the north-eastern part of the Republic of Belarus. The water requirement was established by the methods of water balance and the methods of maximum daily temperature in four experiment variants (three experimental fields plus control (without irrigation)), using sprinkling irrigation equipment. The moisture was measured in the three layers 0 - 30 cm, 0 - 50 cm, 0 - 100 cm. An analysis of experimental data showed that the water requirement difference obtained by two methods do not have significant differ from each other. The water requirement for cutting periods for the natural moisture is: for the first cutting period (from sowing date to the first decade of July) 34,6 - 46,2% (the water balance method) and 30,3 - 41,7% (the maximum daily temperature method), for the second (from the first decade of July to the first decade of August) 17,8 - 33,7% and 21,2 - 29,5%, and the third (the first decade of August until the third decade of September) – 31,7- 42,6% and 36,2 - 40,2% respectively of the total value of the growing season. Water consumption in variants with artificial humidification of cutting periods varied within the following limits: the first – 33,8 - 39,3% (water balance method) and 29,2 - 38,3% (the maximum daily temperature method); second – 20,4 - 33,1% and 22,3 - 29,5%; third – 32,7- 43,8% and 38,9 - 41,6% of the total value of the growing season
