“…Recently, cultivars suitable for late sowing are strongly required to avoid injury from excess water in the rainy season (Fatichin et al, 2013;Takeda & Sasaki, 2013). Although the only cultivar for warm regions that presently possesses E3 is 'Fukuyutaka', 'Fukuyutaka' shows a longer growth duration and the risk of lodging is a concern (Matsuo et al, 2017). Our research suggests that genotypes including the E3 allele may be suitable for late sowing owing to increasing node production while maintaining pod-set ratio.…”

Understanding how maturity genes affect soybean yield formation will provide important information for crop management decisions. This study aimed to reveal how maturity genes E2 and E3 in the soybean cultivar 'Enrei' affect yields and yield formation in warm regions of Japan. 'Enrei' (e2e3) and three near-isogenic lines of 'Enrei' (e2E3, E2e3, and E2E3) were cultivated in 2016 and 2017 in Fukuyama, Japan (34°30′N, 133°23′E). Two sowing dates were set in each year (June sowing and July sowing). E2 extended the period from emergence to R1 and also the period from R1 to R7, whereas E3 extended only the period from emergence to R1. Interaction between E2 and E3 did not affect duration of the period from emergence to R1, but did affect the period from R1 to R7. Although seed yield did not differ between genotypes in the June sowings, the effects of E2 and E3 on seed yield in July sowing were both significant and interaction between E2 and E3 also observed. The total number of nodes increased in E3 genotypes in both sowing dates, especially in E2E3. Pod-set ratio was lower in E2 and E3 genotypes than in e2 and e3 genotypes in the June sowings, but did not differ between genotypes in the July sowings. The high yield of E2E3 genotypes in the July sowings was attributed to increased number of nodes and flower production while maintaining pod-set ratio. Appropriate choice of sowing date is suggested to be essential when using E3 genotypes.

“…In addition to the climatic factors, the extent of crop yield variation may vary geographically according to the types of cultivation, nitrogen fertilization, and soil type and fertility (Adams et al, 1998;Aydinalp & Cresser, 2008;Chen et al, 2014;Fuhrer, 2003). Contribution of cultivar differences has also been reported as an important factor on crop yield for rice (Peng et al, 1999;Saitoh et al, 1993;Zhang & Kokubun, 2004), wheat (Zhou et al, 2007;Ziska, 2008), and soybean (Matsuo et al, 2016(Matsuo et al, , 2017Ziska & Bunce, 2000). In order to analyze so many factors accompanied with huge datasets, models of crop growth are required to estimate and to predict how crop yield responds to the natural environment and cultivation.…”

Long-term trend of crop yields has been widely studied in global scales to find which crops and which geographic regions offer the best hope of meeting food demands, and which regions needed the most improvements. In this study, a mathematical method was applied to analyze spatial patterns in long-term temporal trends of three major crops' yields in Japan archipelago. The changes in annual yields of rice, wheat, and soybean over a period of about 60 years in all 47 prefectures of Japan was analyzed by using the data of agricultural records. For all the three crops, the nationwide yields previously improved, but currently were stagnating in Japan. The result suggests that the annual yields were not improving in 53, 85, and 89% of those prefectures in Japan for rice, wheat, and soybean, respectively. The spatial patterns in temporal trends show that the percentage of number of yield-not-improving prefecture was higher in low latitude regions than high latitude regions. These results highlight the increasingly difficult challenge of meeting the growing demands and stagnating supplies in daily staple foods not only for agricultural scientists but also for Japanese society.

“…DWM is gaining popularity in other countries of the world due to improved quality of water flowing from drained agricultural fields to surface water. The practice has been tested on research facilities in several countries including Lithuania [ 40 ], Sweden [ 41 ], Denmark [ 39 ], Italy [ 42 ], China [ 43 , 44 ], Iran [ 45 ], India [ 46 ], Japan [ 47 ], and Egypt [ 48 ]. Unfortunately, the results of experimental field studies usually include a short measurement period of CD effectiveness.…”

A review with meta-analysis of outflow and nitrate loss reduction in controlled drainage (CD) vs conventional, free drainage (FD) was carried out in the study. Since the results of experimental field studies usually cover short periods of data collection, hence in this paper, meta-analyses were based on model studies that usually cover a longer time range. The databases Web of Science and Scopus were searched for eligible English articles, published until December 2020, that describe the quantity and quality of drainage water. The meta-analysis of outflow and nitrate loss reduction in CD vs FD using the mean difference (MD) with a confidence interval (CI) of 95%. The influence of each study was measured through heterogeneity, sensitivity analyses and publication bias using STATISTICA (version 13.3) for all analyses. Of the 107 works identified, 18 were finally included in the analysis based on established criteria required for an appropriate meta-analysis. In general the results indicate a reduction in average drainage outflow of 30.5% (MD = -71.26 mm; 95% CI, -103.49 –-39.04; p = 0.000) in arable land with CD in comparison to FD practice. In the case of nitrate load the reduction was 33.61% and in the drainage water there was lower content in CD practice by an average of 8.36 kg NO3 ha-1year-1 (95% CI, -9.93 –-6.79; p = 0.000). Subgroup analysis of two meta-analyses indicates that the results concerning these associations may vary with the calculated weight for each article, in which the number of years of study had the most significant impact.
