Summer Maize Growth Estimation Based on Near-Surface Multi-Source Data

Agronomy, 2023
Rapid and accurate crop chlorophyll content estimation and the leaf area index (LAI) are both crucial for guiding field management and improving crop yields. This paper proposes an accurate monitoring method for LAI and soil plant analytical development (SPAD) values (which are closely related to leaf chlorophyll content; we use the SPAD instead 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 ...

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.

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,

Assessing biogeochemical effects and best management practice for a wheat–maize cropping system using the DNDC model [PDF]

, 2014
Contemporary agriculture is shifting from a single-goal to a multi-goal strategy, which in turn requires choosing best management practice (BMP) based on an assessment of the biogeochemical effects of management alternatives.

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 ...
