This paper analysed the maize hybrids from different FAO groups concerning the yield, water use efficiency in the moderate wet area of the Crisurilor Plain. The researches were carried out in the Agriculture Research and Development Station Oradea during 2006-2008 on a preluvosoil. The paper sustains the need of the maize hybrids choise both in unirrigated and irrigated conditions because the yields and water use efficiency are different in the 6 hybrids studied. Irrigation determined the yield gain very significant statistically in all the hybrids and the years. Irrigation determined the increase of the water use efficiency; exception was the earliest hybrid Ciclon.

The researches were carried out at the Agricultural Research and Development Station, Crișurilor Plain, Oradea, during 1990-2016. They have demonstrated that irrigation is needed every year due to the extension of the drought regions in Romania. Irrigation has become a basic element in the technology of the autumn cabbage crop due to the yearly pedological drought. For cabbage, the minimum watering depth is considered 0-50 cm, while an irrigation average rate of 2,410 m3/ha, with a variation range of 1,330-4,900 m3/ha had to be imposed in order to maintain the soil moisture content on the watering depth between the easily available water content and the field capacity. Irrigation improved the microclimate conditions and the ratio water/temperature + light (Domuţa climate index) increased. Daily water consumption increased as well. As a result, total water consumption increased by 70%, with a variation range of 19-872%. Irrigation determined an yield gain of 153%; water use efficiency (kg/m3) increased by 60.0%; irrigation water use efficiency recorded an average value of 13.4 kg yield gain/m3, with variation range 6.7 kg yield gain/m3-24.2 kg yield gain/m3. The correlations quantified in the soil-water-plant system (number of days with pedological drought, yield, respectively yield gain; Domuţa climate index-yield; water consumption-yield) support irrigation for the autumn cabbage crop from Crişurilor Plain.

Plain and the influence of the hybrid, plant density, crop rotation, nutrient supply, weeds and irrigation on water use efficiency were studied. Choosing of the hybrid with the best water use efficiency is very important because a hybrid from 500–600 FAO group (Fundulea 376) in unirrigated conditions and a hybrid from FAO group over 600 (Fundulea 365) obtained the biggest water use efficiency; the hybrid Fundulea 365 obtained the highest irrigation water use efficiency, 20.1 kg yield gain 1 mm-1 irrigation water. One of the most known hybrid in the area is Turda super and the highest water use efficiency was obtained using the plant density of 55 000 plants/ha in unirrigated variant and 70 000 plants/ha in irrigated variant. The highest irrigation water use efficiency, 20.7 kg yield gain 1 mm-1, was obtained at 70 000 plants ha-1. In maize monoculture was obtained the lowest values of the water use efficiency in unirrigated and irrigated variant: in the wheat-maize crop rotation the values were higher than in maize monoculture and in the wheat-maize-soybean were registered the highest values. The same situation was registered regarding the irrigation water use efficiency. Farm manure (30 t ha-1) and especially manure (30 t ha-1) +chemical fertilizers (N90P45) determined a higher values of the water use efficiency in comparison with the control. In the variant with organic + mineral fertilization was registered the higher value (19.4 kg yield gain mm-1) of the irrigation water use efficiency. Water use efficiency was much lower in the variant with weeds in comparison with the variant without the weeds; the differences were of 69% in unirrigated variant and of 64% in irrigated variant, very significant statistically. Irrigation water use efficiency from variant with weeds was lower than the value registered in the variant without weeds; the difference (68%) was very significant statistically. In average in period 1976–2012, the irrigation determined the increasing in water use efficiency with 22%, 19.4 kg mm-1 vs. 15.8 kg mm-1, but not in all the years caused the irrigation increasing in water use efficiency in comparison with unirrigated maize. The results research emphasized the need of the optimization for technology elements studied and a better water use efficiency will be obtained.

The paper is based on the researches carried out in the long term trial placed on the preluvosoil from Agricultural Research and Development Station Oradea, Crisurilor Plain in during 1976–2012. The soil water reserve in 0–75 cm depth decreased bellow easily available water content every year and in 32% of years the soil water reserve decreased bellow wilting point. For optimum water supply an irrigation rate of 2665 m3 ha-1 (variation interval 500–5090 m3 ha-1) was needed. The irrigation determined improving of water/temperature + light report (Domuta climate index) with 47.4% in average in the period May–September. A statistically very significant connection was quantified between this indicator and the yield. Daily water consumption increased in the irrigated variant, the biggest difference in comparison with unirrigated variant was registered in August, 86% in comparison with unirrigated variant. As consequence, the value of the total water consumption increased with 50%, variation interval was 11–154%. The irrigation covered 37.8% of total water consumption, the variation interval was 8.3%–67.9%. The yield level of the sugarbeet increased in average with 61%, the variation interval was 9–227%. Standard deviation was lower in the irrigated variant and this emphasizes an improve of the yield stability with 25.1%. The sugar content of the sugarbeet roots from irrigated variant increased statistically very significantly in the droughty years and differs significantly in the rainy years. Water use efficiency increased in the irrigated variant with 7% and irrigation water use efficiency was between 7.9 kg yield gain 1 m-3 irrigation water and 17.4 kg yield gain 1 m-3 irrigation water. The positive influence of the irrigation on microclimate, water consumption, yield level, stability and quality and on water use efficiency sustain the need of the irrigation in sugarbeet from Crisurilor Plain.

Sowing Season

The objective of this work was to evaluate commercial maize hybrids, under conventional sprinkler irrigation, in two sowing seasons (July and August 2017), in the municipality of Teresina, Piauí. A randomized block design was used, with two replications and 39 treatments (commercial maize hybrids). The characteristics evaluated were grain yield, water use efficiency, number of ears and number of grains per area. For the experiment with sowing done in July 2017, the average grain yield was 9.82 Mg ha-1 and the water use efficiency was 1.9 kg m-3, which are, respectively, 4.7 % and 15.8 % higher in relation to the experiment with sowing done in August 2017. Regardless of the sowing season, grain yields over 10.0 Mg ha-1 of three hybrids (LG 6418, CD 3880 PW and 2A 401 PW) stand out. The yield components, number of kernels per ear and grain mass per ear, show high values of correlation (over 0.80) with grain yield.
