Genetic and agronomic approaches for improving nitrogen use and maize productivity
Several factors have large effects on maize grain yield including environment, nitrogen (N) supply, and hybrid genetics. Efficient and environmentally responsible use of N fertilizer is a cornerstone of high‐yielding maize production, and improvements in maize N use will require a combination of …

Soil conservation in relation to maize productivity on sub-tropical red soils in Yunnan Province, China
… reducing soil loss, which do not decrease crop productivity on sloping land currently under cultivation. At present, very little research has addressed these issues. A research project, building on existing work from 1993-1996, was initiated in 1998. The aim was to test the hypothesis that …

Effects of Cultivation Techniques on Maize Productivity and Soil Properties on Hillslopes in Yunnan Province, China
… have more than doubled, for example mean maize yields have increased from 1.54 to 3.91 t ha-1 from 1960 to 1998. Despite this, food shortages remain major problems. These pressures have also led to intensive cultivation of sloping lands, making China the country with the most serious soil …

Changes in soil properties and their effects on maize productivity following sesbania and pigeon pea improved fallow system in Eastern Zambia
… of 1-3 years have a potential to increase maize yield without additional inorganic nitrogen fertilizers. The mechanisms responsible for improved maize yield are partially understood. therefore the objective of the study were (1) to quantify some changes in soil properties that may be …

Effects of green manure cover crops on weed population, peal, millet and maize productivity under conservation agriculture in Liselo and Mashare Namibia
… that are affordable and can improve their productivity. The integration of green manure cover crops (GMCCs) as rotational crops has been investigated to great lengths in Latin America and reported to improve productivity but information on their use is still scarce in Namibia. Two …

Response of maize to selected productivity traits and biological nitrogen fixation in cowpea-maize combinations under conservation farming system.
Maize productivity among the smallholder farmers in Zambia is generally low, resulting in average national grain yield of 2.3 tons per hectare. This challenge is mainly attributed to low and erratic rainfall, low soil fertility, and poor farming practices. This study was conducted to (i) evaluate …

Rural credit and agricultural productivity; does access to credit matter? evidence from smallholder maize farmers in Zambia
… whether access to credit improves agricultural productivity. Productivity improvement are key to reducing wastages and sustainably increasing household incomes, and ultimately, their economic welfare. This paper assesses the impact of access to credit on agricultural productivity among …

A tripartite study on Bayesian estimation of photosynthetically active radiation, impacts of future climate, and adaptation strategies on crop production: a spatial model framework for the Eastern Kansas River Basin
… of providing location-specific insight on crop productivity and water use management. More so, improvement in process-based crop model inputs such as photosynthetically active radiation (PAR) is essential to enhance model accuracy, while also documenting new estimation methods. The ultimate goal …

Genetic analysis for heat tolerance in tropical maize (zea mays)
Maize is a third important cereal crop in the world after wheat and rice. Its production is however hampered by both biotic and abiotic factors. Among the abiotic factors, heat stress has been reported to cause yield losses of about 1 to 1.7 % per day for every rise in temperature above 30◦C. …

Interactive effects of n fertilization rate, cultivars and planting date under climate change on maize (zea mays l.) yield using crop simulation and statistical downscaling of climate models
… low soil fertility and climate change influences maize (Zea mays L.) growth and yield. Local-scale impacts of future climate change (CC) and variability (CV) on PD, N fertilizer rate (N), cultivar, maize growth, and yield is not well documented in Zambia. The impact of climate change and extreme …
