“…This phenomenon may occur due to the higher gLAI and P n in the grain-filling stage, accompanied by an increase in the grain-filling rate in the later reproductive stage and longer grain-filling duration, especially the middle grain-filling period, which resulted in the higher DMA at the post-silking stage and had a strong influence on the yield formation, which is consistent with the results of Zhai [1]. However, long-term RT treatment caused high soil bulk density, which affects the soil microbial populations and enzyme activities and limits both root growth and uptake of moisture and nutrients, ultimately affecting crop growth and productivity [18,22,38]. The availability of soil water for plants is a major determinant in the yield potential [39].…”

“…Even when supplemental irrigation was applied at the big flare stage, a higher soil bulk density reduced water infiltration, which resulted in an increase in surface runoff; therefore, the soil water storage in the deep soil decreased. This resulted in an undesirable soil water environment for summer maize, especially for root growth [22,34,35], which may lead to abnormal growth of shoot parts [6,31] and decreased gLAI.…”

“…In addition, by improving the soil structure, and establishing ideal conditions for root development and maintaining root activity, the practice of SS can effectively improve the water and nutrient supply to the aboveground portions of plants during grain filling [4]. This effectively delays plant senescence [20,21], and thereby increases yields and the water use efficiency (WUE) [22]. Sun [4] pointed out that SS tillage increased green leaf area index (gLAI), ear-leaf net photosynthetic rate (P n) and the chlorophyll fluorescence characteristics by enhancing dry matter accumulation (DMA) at the post-silking stage.…”

In the southern Huang-Huai-Hai (HHH) region, China, maize production is frequently threatened by waterlogging at the seedling stage and by drought at the big flare stage. A two-year field experiment was performed to explore whether subsoiling (SS) in the winter wheat season could improve the photosynthetic capacity and increase the water use efficiency (WUE) of summer maize using the variety, Luyu9105. A split design was adopted in the experiment. The main plots used tillage practices, including SS and rotary tillage (RT). The subplots consisted of two irrigation methods, i.e., applied supplemental irrigation at the big flare stage (I) and no irrigation at the big flare stage (NI). The results showed that the SS treatment significantly increased soil water content (SWC) in the 40–60 cm soil layer. The SS treatment improved green leaf area index (gLAI) by 15.1%–30.2%, and enhanced the ear-leaf net photosynthetic rate (Pn), stomatal conductance (gs), intercellular CO2 concentration (ci) and transpiration rate (Tr), and was accompanied by an increase in the grain-filling duration (T) by 5 days and the mean grain-filling rate (Va). The SS treatment decreased the stomatal limitation (Ls), indicating that RT treatment, which was under lower SWC, led to a decrease in Pn. Applied supplemental irrigation under RT treatment was able to compensate for the growth of leaves, but could not reverse the decreasing trend in the gLAI. Ultimately, the SS treatment improved WUE by 9.1%–9.9%, and increased grain yields by 10.0%–29.3%. Therefore, this study showed that in the southern Huang-Huai-Hai Plain, which has a yellow cinnamon soil type, the practice of SS can improve the photosynthetic characteristics of leaves and WUE of rainfed summer maize.

“…Tillage and nutrient management especially the N are the key factors to affect crop yield including maize (Shi et al, 2016;Wasaya et al, 2017). Deeply ploughing the soil may lead to lower soil bulk density and results in improved crop yield (Chatterjee and Lal, 2009;Cai et al, 2014).…”

Soil ploughing up to required depth and time of nitrogen application at different growth stages are important practices for enhancing crop yield. The effect of different tillage systems and nitrogen application at different growth stages on yield and yield components of hybrid maize was studied through 2-years field experiment. The experiments were laid out in RCBD with split plot arrangements and main plots were allocated to tillage treatments viz. (T1: Conventional Tillage (2-Cultivation), T2: Tillage with mould board plough + 2-Cultivation, T3: Tillage with Chisel plough + 2-Cultivation) while subplots to nitrogen timings viz. (Whole at sowing (N1), ½ at sowing + ½ at V5 (5-leaf stage) (N2), ½ at sowing + ½ at tasseling (N3), ½ at V5 + ½ at tasseling (N4), 1/3 at sowing + 1/3 at V5 + 1/3 at tasseling (N5). The results indicated significant improvement of yield and yield components through tillage and split application of nitrogen. Plots ploughed to deeper layers with chisel plough resulted higher grains weight per cob (127.65±3.43; 134.45±3.66), 1000-grain weight (272.18±3.33; 306.40±3.08) and grain yield (6.30±0.11; 7.04 ±0.13) during 2008 and 2009, respectively. Nitrogen application in three splits i.e. 1 /3 at sowing + 1 /3 at V5 + 1 /3 at tasseling resulted increased grains weight per cob, 1000-grain weight and grain yield. Interactive effect of tillage and nitrogen treatments on maize gain yield found significant in 2008 while non-significant in 2009. Higher grain yield was recorded with chisel plough along with N application in three splits during both study years. From current study, it may be concluded that farmers should grow maize hybrids by cultivating the soil using chisel plough along with cultivator and applying nitrogen in three splits to obtain higher grain yield.

The North China Plain (NCP) serves as China’s second most important maize production region. Rotary tillage, a popular method used in winter wheat/summer maize systems in the region, has adverse effects on maize production. The current study was conducted to determine whether rotary tillage after subsoiling in the winter wheat season (RS) improves the grain-filling rate and yield of summer maize by decreasing soil bulk density, when compared with rotary tillage (R), in the NCP. The RS treatment decreased soil bulk density and increased soil moisture in the summer maize season when compared with the R treatment. Root number under the RS treatment at 8 collar and silking stages was 22.4−35.3% and 8.0−11.7% greater than under the R treatment, respectively. The RS treatment significantly enhanced the grain-filling rate and grain weight as compared to the R treatment. Yield, thousand grain weight, biomass, and harvest index under the RS treatment were 7.7, 7.2, 2.3 and 5.3% higher than under the R treatment. Thousands grain weight was correlated with soil bulk density and soil moisture after silking. Consequently, the increase in grain weight and yield of summer maize resulted from the decrease in soil bulk density and a consequent increase in soil moisture, root number and grain-filling rate.
