The generally accepted viewpoint that sweet corn has been handed down through the ages by the American Indians from pre-Columbian times is challenged in this article regarding it as a mutation of dent corn which may occur at any time and anywhere that extensive areas of field corn exist. 
Recurrent Mutation and Genome Evolution: Example of Sugary1 and the Origin of Sweet Maize
TLDR
It is determined that five independent mutations have been selected for su1 from 57 cultivars of su1 maize and three of these five alleles were single base pair changes at highly conserved sites and a fourth was a 1.3-kbp transposon.
aboratory efficacy of an anthraquinone-based repellent for reducing ird damage to ripening corn ames
Wildlife repellents provide a non-lethal alternative for managing agricultural impacts associated with wildlife depredation. To evaluate a potential bird repellent for ripening corn, we conducted a
In-vitro evaluation of xanthine oxidase inhibition and antioxidant capacity of water extracts of corn silk (Zea may L.)
Corn silk appeared as yellowish/brownish silky fine soft thread and are ascribed as stigmata of corn or sweet corn. They are the female flowers of Zea mays L. (corn) or Zea mays convar. saccharata
Impacts of Drought Stress and Planting Methods on Sweet Corn Yield and Water Use Efficiency
Seasonal drought is the most important factor to limit the production of maize in the world. Using a split plot design, a two year field experiment was conducted to determine the effect of limited
INVESTIGATION ON YIELD, YIELD COMPONENTS AND SECONDARY TRAITS OF SWEET CORN AS AFFECTED BY DIFFERENT IRRIGATION LEVELS ANS PLANTING METHODS
A two year experiment was taken in order to evaluate sweet corn (Zea mays var. saccharata) yield, morphological and phenological traits in response to limited irrigation and different planting
Bioactives Derived from Ripe Corn Tassels: A Possible New Natural Skin Whitener, 4-Hydroxy-1-Oxindole-3-Acetic Acid
TLDR
There are no prior reports of bioactives derived from corn tassels with potential skin whitening activity, nor are anycorn tassel bioactivities currently employed as ingredients in personal care or skin care products.
THE EFFECTS OF THE METHOD OF CULTIVATION AND LEAF FERTILIZATION WITH BORON IN SOME OF THE CHARACTERISTICS OF VEGETATIVE GROWTH FOR THREE HYBRIDS OF SWEET CORN IN THE SPRING SEASON
This study was undertaken to evaluate the performance of cut Dendrobium pink sunshine under various holding solutions at post graduate lab Department of Horticulture, Faculty of Agriculture,
Effects of Fertilization on the Growth and Yield of Sweet Corn under No Tillage in Bukidnon, Philippines
  • Ronley C. Canatoy

TLDR
The application of fertilizer materials in Bukidnon soil under no tillage operation has no significant effects towards the growth performance of sweet corn and the full recommended rate of inorganic fertilizer plus 1 ton Vermicompost consistently gave significantly higher yield parameter values than those with no fertilizer applied.
Palaeontological evidence for defining the Anthropocene
Abstract Palaeontology formed the basis for defining most of the geological eras, periods, epochs and ages that are commonly recognized. By the same token, the Anthropocene can be defined by diverse
