Crops are grown in a field having soil, which has field capacity of 30 \% and permanent wilting point of 13 \%. The effective depth of root zone is 80 {cm}. Irrigation water is supplied when the average soil moisture drops to 20 \%. Consider density of the soil as 1500 {kg} \/ {m}^{3} and density of water as 1000 {kg} \/ {m}^{3}. If the daily consumptive use of water for the crops is 2 {mm}, the frequency of irrigating the crops (in days), is
