We used corn seeds from maize (Zea mays L.) of the Dnieper 196 SV hybrid to analyze pre-sowing seed bacterization and treatment with biogenic silicon that could be promising in growing hybrids. The chlorophyll content leaves plants gradually increased growth phases reached its maximum phase milky ripeness grain under presowing Paenibacillus polymyxa KB Biogenic Silicon (BSi). yield during both ...

Aflatoxin contamination of corn in the field is influenced by several factors. In the southern U.S., insect populations are usually large every year. Drought caused by warmer and drier than normal weather is conducive to A. flavus infection and aflatoxin contamination of corn, Zea mays L. When loose-husked hybrids are used in the southern U.S., they accentuate insect damage and aflatoxin contam...

The effects of a nutrient-based feeding stimulant, Coax, and a stilbene-based optical brightener, Blankophor P167, on the activity of the nucleopolyhedrovirus of the fall armyworm, Spodoptera frugiperda (J. E. Smith) (SfMNPV) on transgenic sweet corn, Zea mays L., expressing a CryIA(b) toxin from Bacillus thuringiensis (Berliner), were studied in the laboratory. Both Coax and Blankophor P167 in...

We developed a computer model for simulating the population dynamics of the almond moth, Cadra cautella (Walker). The model incorporates previously published life history data for the almondmothdeveloping on storedpeanuts, Arachis hypogaeaL., including stage-speciÞc immature developmental time and survival and adult longevity and fecundity. The model was modiÞed so that it also could be used to...

Sweet corn (Zea mays L.) producers desire high yields and high sugar content in the endosperm. High irrigation levels result in high yield, but their effect on sugar content is unclear. The effects of two irrigation levels, standard and stressed on endosperm sugar content were evaluated using three sugary1 hybrids over 2 years. No significant differences were found among the treatments when ave...

Field research for exploring the impact of winter cover crops (WCCs) integration into cropping systems is resource intensive, time-consuming and offers limited application beyond study area. To bridge this gap, we used APSIM model, to simulate corn (Zea mays L.)-rye (Secale cereale L.)-corn-rye corn-rye-soybean (Glycine max rotations in comparison with corn-corn corn-soybean across state Illino...

Crop yield and economic profitability, both highly dependent on local crop management, soil characteristics, weather conditions, are among the most influential factors to consider when considering a cropping system. The objective of this study was compare returns three different 4-yr diverse rotations with that 2-yr traditional rotation in eastern South Dakota. included were (a) corn (Zea mays ...

The aim of this study was to evaluate the response corn (Zea mays L.) grain yield nitrogen (N) fertilizer application and its residual effect on soybean [Glycine max (L.) Merr.] seed yield. During 2021 growing season, a corn-soybean rotation continued at Scandia, KS (USA), evaluating five N rates (0, 53, 107, 161, 214 lb N/a) applied in under both dryland irrigated conditions. Average yields ra...

Washing of excised corn (Zea mays L., variety WF9xM14) root tissue is accompanied by an increase in (Mg(2+) + K(+))-stimulated adenosine triphosphatase. This is the adenosine triphosphatase described by Fisher, Hansen, and Hodges as positively correlated with ion accumulation rates. The increase in activity is confined to the microsomal fraction. A close parallel exists between increases in ade...
