Weekly top soil moisture contents: The experimental field received 90.2 mm rainfall in the
1st and 2nd week after planting and 28.0 mm in the 4th and 5th week. In total, 118.2 mm of rainfall added to soil moisture before starting irrigation of 0.5 x ET0 and 1.0 x ET0 started in the 8th week after planting. Soil moisture in all plots slightly decreased after the last rainfall of the experimental period (Figure 1). After the 8th week after planting, soil moisture in the plots was clearly affected by irrigation treatments. Consequently, rainfed condition plots had the lowest soil moisture in the 9th week and highest soil moisture was found in the 1.0 x ET0 plot. Similarly, the differences were continuously the same until the final 15th week. Gravimetric soil water content after the 8th week of 1.0 x ET0 plots was around 10 to 12%, 0.5 x ET0 plots were around 8 to 11% and rainfed condition plots slightly decreased from 8% in the 9th week to 4% in the 15th week
