At 50% DI in EOF, only a small part of the profile did not get RAW. Soil moisture was higher than 70% of FC in the 30-100-cm layer, mostly in the range 81-86% of FC. After the 2 nd application the top 30-cm layer remained dry. At 50% DI in ETF, RAW in the range 70-86% of FC was established generally in the layer 40- 100 cm (Figure 6). At 67% DI in EOF, the root zone 1-m in depth × 35 cm radially was moisturized in the range 70-89% of FC. The driest parts were located under the dry furrow and the adjacent row in the top 0-20 cm. At 67% DI in ETF, RAW after the 1 st application was established in the lower 50- 100-cm soil layer and after the 2 nd one – under the wetted and furrow mainly (Figure 6). Longitudinal mosturizing (along the furrows) in wide-spaced irrigation was uneven (Figure 7 and 8). At full irrigation in EOF – soil moisture was high and uniformly distributed only under the wetted furrow. Under the row and the dry furrow RAW was discovered in the right part of the profile. At 50% DI the available water in soil profile was below 50 cm. At 67% DI in EOF the top 20 cm under the wetted were dry 48 h after the application was given. The remaining part of the profile was evenly moisturized in the range 70-93% of FC. Plants could take water from beneath 40 and 60 cm under the row and the dry furrow. The moisture in the layer 40-80 cm was between 70 and 80% of FC, and in the 80- 100-cm layer – more than of 80% of FC. At full irrigation in ETF, moisture under the wetted furrow was readily available through the whole profile, but with higher values at the end of the furrows. This was the tendency under the whole plot, the dry furrow and the adjacent rows inclusive. No tendency of moisture distribution was noticed at DI in ETF, due probably to the small amount of the given water (Figure 8). Irrigation impact was significant in all variants of irrigation and water deficit applied (Table 2 and 3), except for 67% DI in EF and in ETF in 2010. The yield under rain-fed conditions in both years was 6.92 and 7.09 Mg/ha respectively. Relative yield varied from 126.6% to 140.3% in 2009 and from 104.7 to 127.9% in 2010. Yield increase was considerably small due to the mid and mid-moist conditions considering rainfalls and air humidity, which favored the yield accumulation under RF (col. 7 and 8 of Table 2 and 3). Figure 5. Dynamics of soil moisture through the vegetation period in 2010 Water deficit had significant effect in all studied cases, except for 50% DI in EOF in 2009. The latter proved to be efficient. Like yields were obtained by 50% of the needed irrigational water distributed in EOF and by the full needed amount. The relative yield was 94.2% since the increase in WUE compensated the lack of water. 265
