“…Thus, it is necessary to explore the potential of rice production systems to meet the present and future food requirements (He et al 2019;Liu et al 2019a). Nitrogen (N) is one of the crucial and yield-limiting nutrients for rice (Fageria et al 2011), whereas the consumption of chemical fertilizers in China from 2000 to 2014 was increased by about 1.41 m tons annually due to its overuse by the farmers to achieve maximum crop yields (Chen et al 2018;Wang et al 2018). Application of chemical fertilizer per unit area is about 490 kg ha −1 , more than 2-fold of its use in developed countries, i.e., 225 kg ha −1 .…”

The purpose of this study is to understand how grain yield and nitrogen use efficiency were affected by straw incorporation coupled with deep placement of nitrogen fertilizer in direct-seeded rice in South China. The experimental treatments comprised deep placement of N fertilization coupled with straw return (DS) and without straw return (DO) as well as surface broadcasting of N fertilizer coupled with straw return (SS) and without straw return (SO), whereas no fertilizer placement and no straw return were taken as a control (FS0) in two rice cultivars, i.e., Yuxiangyouzhan (YX) and Wufengyou615 (WF), grown in early and late season of 2018. Results depicted that, compared with FS0, DS significantly (P < 0.05) improved grain yield by 68.7-115.9% owing to higher net photosynthetic rate (Pn) at the heading stage, larger total aboveground biomass, and leaf area index (LAI). Compared with DO, the nitrogen recovery efficiency (NRE) and nitrogen agronomic use efficiency (NAE) in DS were increased by 19.3-188.6% and 1.9-33.8%, respectively. Furthermore, the nitrate reductase (NR) activity of the flag leaves at heading stage for DS was increased by 10.6-93.0% as compared with DO treatment. Therefore, straw incorporation coupled with deep placement of nitrogen fertilizer could be a feasible technique with the increase of grain yield and nitrogen use efficiency in direct-seeded rice (DSR) in South China.

“…Therefore, sustainable management systems for intensive maize production are sought. Crop rotation affects the sustainability of agricultural production systems 2–4 . Often, crop rotations involve legumes since they are capable of fixing nitrogen.…”

“…It is well known that legumes do add organic N and their biomass improve soil properties and activities of microorganisms. However, agriculturists believe that the resultant subsequent crop improvement will differ depending on prevalent legume system 4,11 . Green manure crops when incorporated into the soil are known for their improvement of soil properties 12 and yield of crop grown after them 13 but the question is can maize be sustainably grown after legumes the same year and on the same piece of land for sustainable intensification of maize production?…”

Inclusion of legumes in cropping systems is essential for sustainable management of farming systems and reducing the nitrogen (N) fertilizer requirement for maize production. The study evaluated the effect of growing legumes (soybean, cowpea and velvet bean) and maize the same year in rotation, on maize yield and soil fertility indices. The agronomic practices implemented were residue management (residue added and residue removed) and fertilizer N application (0 kg N ha −1 and 60 kg N ha −1 ) under four rotation systems. The result showed that growing velvet bean the same year in rotation with maize was effective in increasing maize yield and improving some soil fertility indices over growing maize after maize the same year in the same location. Compared to maize monocropping, over 100% increase in maize yield was obtained with velvet bean-maize rotation even in absence of residue incorporation. In addition, velvet bean-maize rotation increased maize yield over cowpea- and soybean- maize rotations. The rotation effect occurred as a result of improvement in soil nitrogen, avail phosphorus (P), exchangeable magnesium (exch Mg) and effective cation exchange capacity (ECEC). Grain legumes-maize rotations equally increased maize yield over sole maize. Generally legume-maize rotations increased total N, avail P, exch K, Mg and effective cation exchange capacity over sole maize. Crop residue incorporation and N fertilizer application significantly improved soil N and maize grain yield (0.18%, 2.74 tha −1 in 2008; 0.22%, 1.16 tha −1 in 2009 and 0.19%, 2.72 tha −1 in 2008; 1.35 tha −1 in 2009 respectively) over non-residue incorporation (0.16% and 1.84 tha −1 in 2008, 0.66 tha −1 in 2009) and zero N application (0.16% and 1.83 tha −1 in 2008 and 0.17% and 0.85 tha −1 in 2009). Therefore, velvet bean could be planted the same season with subsequent maize in rotation cropping for intensive sustainable maize production in sandy-loam soils without fertilizer N. For grain legumes such as soybean and cowpea to be effective in rotation cropping with maize, the grain legumes have to be planted early before the full set of rain because excess rain would affect their growth and development.

“…However, photosynthesis is negatively affected by high temperature, as crop transpiration and soil moisture evaporation are enhanced, and crop growth is inhibited. Climatic warming accelerates evaporation from vegetation and may further inhibit crop photosynthesis and dry matter accumulation (Picotte et al ., 2007; Chen et al ., 2018). Substantial research has been carried out on the impact of climate change on plant water use efficiency (WUE) in China and the rest of the world (Lei et al ., 2016).…”

Global warming will directly influence agricultural production and present new challenges for food security in semiarid regions of China. A warming experiment was conducted in Guyuan, China using infrared ray radiators to study the impact of warming on crop growth, yield and quality of a potato–broad bean–winter wheat crop rotation system. Warming significantly affected the crop photosynthesis rates of the potato–broad bean–winter wheat rotation system. In the podding stage of broad bean and the heading, blooming and booting stages of winter wheat, the photosynthesis rate was significantly decreased when the temperature increased by 0.5–2.0°C. The growing period of the potato–broad bean–winter wheat rotation system was shortened by 20–40 days per 3-year-period, and the fallow period was prolonged by 4–13 days per 3-year-period. The water use efficiency of the potato–broad bean–winter wheat rotation decreased by 8.6% when the temperature increased by 1.02.0°C. The yield of the potato–broad bean–winter wheat rotation increased by 6.1–7.7% when the temperature increased by 0.5–1.0°C. However, yield decreased 12.9–13.4% when temperature increased by 1.0–2.0°C. Potato protein significantly decreased by 9.3–17.6% and the winter wheat fat significantly decreased by 6.7% when the temperature increased by 0.5–2.0°C. The results indicate that global warming could seriously affect the crop growth, yield and water use of the potato–broad bean–winter wheat rotation in semiarid regions of China.
