“…The lower return in the control treatment (WS0) relative to Si treated plots, was probably due to less Si and N interactions, which resulted in inadequate N for the crop to produce a higher yield. A similar observation was reported by Xu et al [23], who found that the application of Si improved maize grain yield and dry matter accumulation. These findings could contribute to the further understanding Si fertilizer enhances dry matter production and grain yield.…”

Aims: To investigate the effect of silicon (Si) fertilizer and Si fertilizer with straw return in potassium (K) and maize grain yield. Methods: In 2018 and 2019, two field experiments were established in Nong’an county, Jilin province. Four treatments were arranged in a randomized block design: JS3 (straw return + Si), WS3 (no straw return + Si), JS0 (straw return + no Si) and WS0 (no straw return + no Si). Results: In comparison with WS3, the average soil available K for WS0 was 22.1% lower. Similarly, compared with JS3, the average soil available K for WS3 was even decreased by 3.1%. The plots amended with Si fertilizer (15.9% WS3) significantly increased K uptake than that of WS0, and the total uptake of K under JS3 increased by 7.5% compared with that under WS3. The total dry matter and grain yield were significantly higher under WS3, which increased by 6.5% and 4.8% respectively, and JS3 significantly outperformed WS3 by 2.9% and 1.3% for total dry matter and grain yield. Conclusions: Our results indicate that the application of Si fertilizer improves K availability, uptake and crop yield, and the use of Si fertilizer with straw return sustainably improves K release to meet crop requirements while increasing crop productivity.

“…Photosynthesis is a basic physiological process for plant growth and dry biomass accumulation and the main factor affecting maize grain formation during grain filling stage (Xu et al,2016). Pn of ear leaf in maize could partly indicate the photosynthetic capacity, thus it is the key factor to determine grain yield (Kim et al, 2006).…”

This study aims to investigate the responses of carbon assimilation, grain yield, leaf stay-green rate, nitrogen uptake and distribution to soil compaction in the hard plow pan caused by repeated use of tractor-driven cultivator in Northeast China. The typical hybrid maize variety “Zhengdan 958” was exposed to two treatments of simulated plow pan (SP) and simulated subsoiling (SS, control) in pot experiments from 2012 to 2014. Compared with SS, SP significantly reduced net photosynthetic rate (Pn) during growth stage, leading to a decrease in dry matter accumulation (DMA) and grain yield (GY) in three consecutive experimental years. Leaf stay-green degrees (LSD), which showed a fast descending trend from 20 days after silking (DAS), significantly decreased in the later filling stage under SP treatment. The translocation eﬃciency of the stored N (TEN) in stalk and leaf to the grain during pre-silking was enhanced, whereas leaf and grain N concentration (LNC/GNC), together with N accumulation amounts at maturity were significantly reduced under SP treatment. Also, plough pan reduced the N distribution to the organs of stalk, leaf and grain. In conclusion, subsoiling is a possible way to delay leaf senescence and achieve higher DMA and GY, and increased grain N in the corn belt of Northeast China.

The success of a hybrid breeding program is dependent on available heterotic patterns for exploitation of grain-yield heterosis. The efficiency of the assignment of germplasm lines into heterotic groups is a prerequisite for obtaining useful heterotic patterns among germplasm lines. A total of 256 maize hybrids, comprising 244 top crosses, six diallel cross hybrids, and six checks, were grown under Striga infestation, drought, and optimal conditions, from 2015 to 2017. The study determined the combining abilities of the parental inbreds, classified the inbreds into heterotic groups, and compared the efficiencies of the following four grouping methods for classifying the inbreds: specific combining ability (SCA) effect of grain yield; general combining ability (GCA) effects of multiple traits (HGCAMT); SCA and GCA (HSGCA) for yield; and single nucleotide polymorphism-based genetic distance (SNP-based genetic distance (GD)). Significant GCA and/or SCA mean squares were revealed for most measured traits in all test environments. Sums of squares (SS) due to GCA were higher than SCA SS for measured traits in all test environments. The HSGCA, SCA, and SNP-based GD methods identified four heterotic groups, whereas the HGCAMT identified three groups, in all environments. The additive gene effect was preponderant in the inheritance of most measured traits. The efficiencies of the grouping methods varied with the test environments. The HSGCA and SCA methods were the most efficient for grouping in all test conditions. For practical breeding purposes, the HGCAMT and HSGCA methods were recommended under Striga infestation and drought, respectively. The heterotic patterns, which were revealed in this study, were effective for planning hybridization schemes for developing high-yielding, Striga-tolerant/resistant, and drought-tolerant maize hybrids for stressful environments.
