“…Chemical fertilizer is an important input in grain production, known as the "food" for grain. Serving as one of the most fundamental determinants of grain yield, chemical fertilizer contributed more than 40% to the improvement of China's grain yield [1], and played an irreplaceable role in ensuring China's food security [2,3]. The average chemical fertilizer usage per hectare in China's grain production increased from 258.54 kg/ha in 1997 to 362.99 kg/ha in 2014, then began to decrease since 2015 and arrived at 340.77 kg/ha in 2018, but still 31.81% higher than that in 1997 [4].…”

“…There are two types of method for measuring chemical fertilizer use efficiency for grain production: the index method [2,[25][26][27] and the model method [1,[28][29][30]. The index method mainly includes the Recovery Efficiency Index, Partial Factor Production Index, Agronomic Efficiency Index, and Physiological Efficiency Index [2], which measure the proportional relation between yield and intensity of chemical fertilizer from the perspective of agronomy; the index method is easy to understand, but fails to holistically reflect whole input-output process in grain production because treating chemical fertilizer as the only input.…”

Low technical efficiency and excessive usage of chemical fertilizer in grain production is a problem commonly faced by China and many other developing countries, which leads to serious environment pollution and high environmental governance cost. China is the largest rice producing and consuming country, and several kinds of rice are grown in China and all of which are important edible grain. However, there has been no systematic research on kind difference and provincial difference of technical efficiency of chemical fertilizer use (TEFU) for rice production. Using the data of China’s 22 rice production provinces from the China Agricultural Product Cost-Benefit Compilation and the China Statistical Yearbook, this study measures the TEFU for early indica rice, intermediary indica rice, late indica rice, and japonica rice production by using a stochastic frontier production function (SFPF) model, and then analyzes TEFU’s influencing factors using a Tobit model and conducts the robustness check using a panel data fixed effect model. We found that, on average, TEFU for four kinds of rice production were improved significantly during 1997–2018, increasing by 67.70%, 39.93%, 14.76%, and 21.88%, respectively. TEFU for China’s rice production have significant differences among different kinds and production provinces, and still have large improvement potential. Government’s fiscal support to agriculture, agricultural labor productivity, agricultural mechanization, effective irrigation, and implementation of the “Soil Testing and Formulated Fertilization Program” (STFFP) have significant positive impact on TEFU; and natural disaster and fertilizer price have significant negative impact on TEFU.

“…Without effective adaptation and genetic improvement, each degree-Celsius increase in global mean temperature would reduce global yields of wheat by 6.0%, on average (Zhang et al 2017). Chemical fertilizer is an important technological measure to offset the impact of natural conditions on the agricultural production process (HU, ZHANG, and ZHOU 2019). The Green Revolution improved grain yields by 126% from 1950 to 1980, and approximately 40-60% of the increase is attributed to the application of fertilizer (FAO, 1961(FAO, -2003.…”

Improving the wheat yield of countries along the Belt and Road (BR) plays a core role in ensuring global food security. However, little attention has been paid to the wheat yield variation and the determinants across these countries. This paper analyzes wheat yield convergence in countries along the BR using the club-convergence test. The empirical results show that instead of one convergence for all countries along the BR, the wheat yields are converging into three clubs. Furthermore, we investigate the impact of climate change and agricultural production technology on wheat yield convergence, and find that countries along the BR with a one degree Celsius increase in temperature are 36.5% (32.7%) more likely to converge to the high-level yield club. This may be related to the lower frequency of frost and higher photosynthetic capacity of wheat. We also find that a one kilogram increase in fertilizer application per hectare will result in a 0.4% (0.5%) higher probability of countries along the BR converging to the high-level yield club. Countries along the BR should pay more attention to coordinating production technologies and climate change to ensure food security.

“…In southern Jiangsu, the value difference is even more pronounced with the per capita cultivated land less than 0.3 mu. Due to the region's limited per capita arable land and dense population, Jiangsu's agricultural production is highly dependent on ferti-lizer usage, resulting in high carbon emission and intensified environmental pressures [37].…”

Achieving eco-efficiency in agriculture production at low environmental costs is key to sustainable agriculture. Using the DEA-SBM model, this study evaluated the agricultural eco-efficiency of the 77 counties and districts in China’s Jiangsu province from 1999 to 2018 and analyzed its spatio-temporal evolution pattern and influencing factors. The mains conclusions were as follows: (1) The overall agricultural eco-efficiency and its decomposition terms, pure technology efficiency and scale efficiency, exhibited a fluctuating downward trend. The regional inequality in agricultural eco-efficiency had been widening and exhibited a strong positive spatial association. (2) The agricultural eco-efficiency in Jiangsu province presented a “high south and low north” spatial pattern. High-level agricultural eco-efficiency areas were in the Taihu Plain in Sunan, while low-level agricultural eco-efficiency zones are distributed across Subei City. The High-High-type spatial association pattern is concentrated in the Suzhou-Wuxi-Changzhou region, while the Low-Low areas are mainly in the coastal regions of Subei and Suzhong. (3) The spatial pattern of PTE and SE generally exhibited a “high south and low north” distribution. Areas with positive growth in agricultural eco-efficiency, PTE, and SE, were situated in Xuzhou, Nanjing city, and the bordering regions between Yangzhou and Huai’an, and Changzhou and Wuxi. (4) The excessive redundant use and application of pesticides, chemical fertilizer, agricultural diesel, labor, land, and agricultural carbon emission have been the primary factor affecting Jiangsu's agricultural eco-efficiency. Irrigation had also signficantly impacted agricultural eco-efficiency, while mechanical power and agricultural film had minimal effect. The majority of counties and districts in Subei, Suzhong, and Ningzhen Yang Hilly region have issues regarding their excessive usage of chemical fertilizer, pesticide, chemical fertilizer, agricultural diesel, labor, and land. The findings of this study can contribute towards a better understanding of agricultural eco-efficiency and spatial association effect and can help policymakers increase agricultural eco-efficiency.
