“…Regardless of fertilization application and rate, (SD) significantly resulted in the least yield compared to the other two irrigation regimes (table 1). It was reported that soybean seed yield decreases under drought stress conditions (Ashley & Ethridge, 1978;Bajaj et al, 2008;Dogan et al, 2007;Doss et al, 1974;Gercek et al, 2009;Heatherly & Elmore, 1986;Karam et al, 2005;Kokubun, 2011;Li et al, 2013;Rose, 1988;Sadeghipour & Abbasi, 2012;Sincik et al, 2008). The yield increased in (MD) compared to (SD), regardless of (N) fertilizer rate; this result is consistent with Dornbos & Mullen (1992) conclusion that severe drought stress reduced the seed yield of soybean more than did moderate drought stress.…”

As a result to continuous exploitation in agriculture, soil nutrients decrease, and one way of re-fertilizing is by mineral fertilization. However, applying mineral fertilizers should be controlled and pre-evaluated in terms of quantity to be added, as the excessive amounts could negatively affect both plants and soil. Fertilization is very important under abiotic stress conditions, like drought stress which has negative effects on both quantity (yield) and quality (seed content) of crops, especially drought-sensitive crops such as soybean; it is a very important legume with high content of both protein and oil. In order to study the influence of both nitrogen fertilization and drought stress on the yield and the seed quality of two soybean cultivars, an experiment was conducted in Debrecen, Hungary in 2017. Three N fertilization rates; 0, 35 and 105 kg ha-1 were applied under three irrigation regimes; severe drought (SD), moderate drought (MD) and no drought (ND). The results showed drought stress to negatively affect the yield of both cultivars by different extents; it also manipulated both protein and oil concentrations. (N) fertilization could enhance the yield of (MD) and (ND), but not (SD) treatment when applied in a relatively-low rate, whereas it negatively affected the yield when high rate was applied to (ND) treatment. The protein concentration increased as the (N) fertilization rate increased, whereas the oil concentration was not affected by (N) fertilization, but rather by drought. It was concluded that the high-rate application of nitrogen is not always recommended for soybean, especially when water is available for plants. (N) fertilization has a noticeable effect on the protein but not on the oil concentration. Further studies on the best N rate when drought stress is applied at certain growth-stage will help to better understand the combined effects of both traits on soybean yield and quality.

“…The greater soil profile moisture under mulch has important implications in the utilization of water by crop and in soil reactions that control the availlability of nutrients and biological nitrogen fixation (Surya et al, 2000) that leads to improved growth and ultimately yield. Since the availability of soil moisture increased the pod number per plant, the yield increase was realised (Bajaj et al,2008). Different seed rates viz 60, 75 and 90 kg ha -1 recorded statistically similar seed yield.…”

A field experiment was conducted for three years to study the effect of sowing dates, mulching and seed rates on nutrient uptake and productivity of soybean under irrigated conditions in sub-humid Punjab on a silty clay loam soil which was low in available N, medium in available P and available K. The experiment was conducted in a split plot design with the combination of three sowing dates and mulch in main plots and three seed rates in sub-plots with three replications on fixed site. The results revealed that sowing on June 30 and mulching recorded the highest number of pods plant -1 .There was no significant influence of seed rates on yield attributes. Seed yield also remained at par under different sowing dates, mulching and seed rate treatments. Stover yield however, was significantly higher under the earlier sowing dates and mulching. Highest total N uptake was observed under June 30 sowing date whereas total P and K uptake was highest in May 20 sowing date. No significant effect of mulching was observed on total N and K uptake. Among seed rates maximum total N uptake was observed under 75 kg seed ha -1 . The results suggest that soybean performed better when sown with 60 kg seed rate ha -1 on June 30 and mulched with wheat straw.

“…The results are in agreement with those given by Payero et al (2005) and Demirtas et al (2010) who also found positive relationship between seasonal evapotranspiration and seed yield of soybean in west-central Nebraska, USA (r 2 -0.74 to 0.82) and western Turkey (r 2 -0.92 to 0.98). y = 0,0074x + 1,1934 R² = 0,6889 r = 0,83** Several studies conducted for a wide range of environments have demonstrated that soybean yield increases with irrigation (Dogan et al 2007, Sincik et al 2008, Bajaj et al 2008, Gerçek et al 2009). In the study period the yield of soybean was on average significantly higher in irrigated (4.559 t ha -1 ) than in rainfed (3.739 t ha -1 ) conditions (Tab.…”

Research was carried out at Rimski Šančevi experiment field of Institute of Field and Vegetable Crops in Novi Sad in the period 1993-2004. The experiment included an irrigated and non-irrigated control treatment. Irrigation water use efficiency (I wue ) and evapotranspiration water use efficiency (ET wue ) were determined in order to assess the effectiveness of irrigation on soybean yield. The average yield increases of soybean due to irrigation practice was 0.82 t ha -1 , ranging from 2.465 t ha -1 in years with limited precipitation and higher than average seasonal temperatures (2000) to 0 t ha -1 in rainy years (1996, 1997, 1999). Evapotranspiration water use efficiency (ET wue ) of soybean ranged from 0.11 kg m -3 to 1.36 kg m -3 with an average value of 0.66 kg m -3 , while irrigation water use efficiency (I wue ) varied from 0.11 kg m -3 to 1.04 kg m -3 with an average value of 0.56 kg m -3 . Effect of irrigation on yield of soybean and results of both ET wue and I wue which were similar to those obtained from the literature indicate that irrigation schedule of soybean in the study period was properly adapted to plant water requirements and water-physical soil properties. Determined values of ET wue and I wue could be used for the planning, design and operation of irrigation systems, as well as for improving the production technology of soybean in the region.
