Quantitative Research on Drought Loss Sensitivity of Summer Maize Based on AquaCrop Model [PDF]

Natural Hazards, 2021
Abstract In this study, the growth periods of summer maize was divided into seedling, booting and flowering-grain stage. Based on the simulation results of AquaCrop model, the drought loss sensitivity of summer maize in different growth periods was analyzed.

Maize grain filling characteristics in China: Response to meteorological factors

Heliyon
To investigate the dynamic changes in dry matter accumulation in maize after anthesis, we established a logistic model to describe grain filling characteristics (GFC), and analyzed differences between spring and summer maize, and the influence of ...

Simulative projection of future choking drought disaster risk of summer maize in the Huaihe River basin under RCPs scenarios

暴雨灾害, 2021
To evaluate the climate variation of drought and its possible effect on summer maize in the Huaihe River basin, we have used the five General Circulation Models (GCMs) from the fifth coupling model comparison scheme (CMIP5) and the diurnal temperature ...

Integrated Weed Management in Summer Maize in Mid-Hills of Nepal

Agronomy Journal of Nepal, 2022
Weed is one of the major problems in maize production. To develop an appropriate weed management practice, a field experiment was carried out during 2017 and 2018 at Khumaltar. Twelve different treatments, Pendimethalin as pre @ 1.0 kg a.i ha-1, Atrazine as pre @ 1 kg a.i ha-1, Metribuzine as pre @ 0.5 kg a.i ha-1, Tembotrione as post @ 0.2 kg a.i ha-1,

Maize/peanut intercropping increases photosynthetic characteristics, 13C-photosynthate distribution, and grain yield of summer maize

Journal of Integrative Agriculture, 2019
Intercropping is used widely by smallholder farmers in developing countries to increase land productivity and profitability. We conducted a maize/peanut intercropping experiment in the 2015 and 2016 growing seasons in Shandong, China. Treatments included sole maize (SM), sole peanut (SP), and an intercrop consisting of four rows of maize and six rows ...

Evaluation of physiological traits of summer maize under drought stress

Acta Agriculturae Scandinavica, Section B — Soil & Plant Science, 2015
ABSTRACTA study was conducted to investigate the sensitivity of physiological traits under different soil water availability in summer maize (Zea mays L.). Plant growth (plant height and stem), water relations (relative water content), gas exchange (net photosynthesis rate, stomatal conductance and transpiration rate) and nutrient levels were measured ...

Soil Compaction and Maize Root Distribution under Subsoiling Tillage in a Wheat–Maize Double Cropping System

Agronomy, 2023
Huang-Huai-Hai Plain is the most important region for grain production in China. In this area, long-term rotary tillage in winter wheat and no tillage in summer maize have significantly increased soil bulk density, which impede maize root growth and ...

Climate change and perennial crop production: Evidence of yield impact and adaptation in California

American Journal of Agricultural Economics, EarlyView.
Abstract Perennial crops are economically important. They contribute to food security, providing essential nutrients that are often lacking in annual crops, and provide additional environmental benefits compared with annual crops. Despite their importance, empirical research on the impacts of climate change and adaptation on perennial crops remains ...
