Effects of co-application of biosolids and water treatment residuals on corn growth and bioavailable Phosphorus and Aluminum in Alkaline Soils in Egypt
The co-application of biosolids and water treatment residuals (WTRs) has been previously trialed to reduce excessive bioavailable P in the soil treated with biosolids. However, uncertainty still exists regarding the environmental consequences of the co-application of biosolids and WTRs, especially in alkaline soils in Egypt or the Middle East region. A greenhouse pot study was conducted with ...

Hairy Vetch management for no-till organic corn production
Rolling-crimping to control hairy vetch (Vicia villosa Roth) may make organic no-till corn (Zea mays L.) possible. This study investigated how rolling-crimping date and growth stage of the cover crop affected hairy vetch control and if a rolled-crimped hairy vetch cover crop could supply weed control for no-till corn. Hairy vetch was planted in late August and was rolled and crimped and planted ...

Corn response to competition: growth alteration vs. yield limiting factors
Competition mechanisms among adjacent plants are not well understood. This study compared corn growth and yield responses to water, N, and shade at 74,500 plants ha–1 (1x) with responses to water and N when planted at 149,000 plant ha–1. Plant biomass, leaf area, chlorophyll content, reflectance, and enzyme expression (transcriptome analysis) were measured at V-12. Grain and stover yields were ...

Breeding maize for a bioeconomy: a literature survey examining harvest index and stover yield and their relationship to grain yield
The use of maize (Zea mays L.) stover as a feedstock for cellulosic biofuels production will create demand for maize hybrids with greater stover yield. It is expected that grain yield will remain the most critical trait and continue to drive hybrid sales, requiring that any increases in stover yield be made without sacrificing grain yield potential. The objective of this review was to determine ...

Can changes in canopy and/or root system architecture explain historical maize yield trends in the U.S. corn belt?
Continuous increase in the yield of maize (Zea mays L.) in the U.S. Corn Belt has involved an interaction with plant density. A number of contributing traits and mechanisms have been suggested. In this study we used a modeling approach to examine whether changes in canopy and/or root system architecture might explain the observed trends. A maize crop model was generalized so that changes in ...

Putative Seedling Ferulate Ester (sfe) maize mutant: morphology, biomass yield, and stover cell wall composition and rumen degradability
Ferulate cross-linking of lignin to arabinoxylan contributes to poor cell wall degradability of grass forages. We hypothesized that reduced ferulate ester deposition will result in formation of fewer ferulate cross links and improved degradability. Objectives were to determine if the putative seedling ferulate ester (sfe) maize (Zea mays L.) mutant, selected for reduced ferulate esters in ...

Improving the ceres-maize model ability to simulate water deficit impact on maize production and yield components
Crop models are potential tools for designing water-efficient strategies and should be tested for accurate prediction of water deficit effects on production. The objective of this research was to test and improve the CERES-Maize model (CERES-4.0) for ability to predict accurately maize biomass and grain yield components under water-limiting conditions in an environment where the model had ...

Maize growth and yield under daytime and nighttime solid-set sprinkler irrigation
Nighttime sprinkler irrigation usually results in lower wind drift and evaporation losses (WDELs) and better irrigation uniformity compared with daytime irrigation. However, daytime sprinkler irrigation modifies the microclimatic conditions within the crop canopy which could result in improved crop growth. We studied the effect of daytime and nighttime irrigation on the growth and yield of maize ...

Effect of biochar on maize yield and yield components in rainfed conditions
Int. J. Agron. Agri. Res. 12(3), 46-51, March 2018. To investigate the maize yield and nutrient concentration in its leaves as affected by biochar from different organic materials (wheat straw and sugarcane bagasse), a field experiment was conducted on maize crop during 2013 at koont research farm chakwal. The treatments were control, wheat straw biochar at 5t ha-1, and 10t ha-1, sugarcane ...
