Root Plasticity Of Selected Corn (Zea Mays L.) Varieties Grown For Food And Forage In Response To Fertigroe®-N And Urea, Vanica Apostol, Edna Aguilar, Lilia Fernando, Lourdes Edano Ma., Tonette Laude, Eureka Teresa Ocampo

The Philippine Agricultural Scientist

Root plasticity, the capacity of a corn root system to modify its growth and development in response to varying environmental conditions, is a crucial adaptability trait for optimizing water and nutrient uptake, especially in a challenging environments. Understanding root plasticity provides insights into the pattern basis of crop adaptation, contributing to the development of improved corn varieties and agricultural practices that optimize the production of both ear shoots and forage. This study assessed root traits and other morphological-physiological responses of three corn varieties (NK8840, IPB Var 6, and Pearl Sweet) grown for food (ear shoots) and forage (baby corn fodder) …

A Brief History Of Corn: Looking Back To Move Forward, Jon Derek Pruitt

Doctor of Plant Health Program: Dissertations and Student Research

Maize was domesticated from teosinte in Mexico some 7,000 to 10,000 years ago and quickly spread through the Americas. It has become one of the most important crops at a local and global level. Two types, Northern Flint corn and Southern Dent corns provided the basis of the genetic background of modern maize hybrids. The development of hybrids, first double-cross and later single-cross hybrids, along with a transition to high input farming provided huge yield increases, which have continued to improve with improving technology.

Increase in maize production also caused a rise in Western corn Rootworm (Diabrotica virgifera virgifera …

Superweeds And Suspect Seeds: Does The Genetically-Engineered Crop Deregulation Process Put American Agriculture At Risk, Margaret Sova Mccabe

Law Faculty Scholarship

The federal government’s regulatory approach to genetically engineered (GE) crops, known as “The Framework”, is now twenty-five years old. Despite two and half decades of a consistent regulatory regime, GE crop and food regulation remains controversial. This article suggests that regulatory science and its tenets of independence, transparency, and public science should guide reforms of The Framework so that it is an efficient and reliable regulatory system. The article has four parts: 1) it provides a brief overview of the history of GE crop regulation; 2)it describes the key attributes of The Framework and related regulatory documents, with particular focus …

The Effects Of Irradiating Dormant Maize Seeds With Xrays And Thermal Neutrons, Rosalind Morris, E. F. Frolik

Nebraska Agricultural Experiment Station: Historical Research Bulletins

In 1951 a research program was started at the University of Nebraska to compare the developmental effects of thermal neutrons and X rays on different crop seeds. Three crops, barley, tomato and maize, were chosen for additional information involving induced chromosomal aberrations and seedling mutations. The maize investigations are presented in this bulletin, along with a comparison among the three crops with respect to irradiation effects.

Progress From Recurrent Selection Procedures For The Improvement Of Corn Populations, John H. Lonnquist

Nebraska Agricultural Experiment Station: Historical Research Bulletins

The possibilities of developing synthetic varieties suitable for the fringe areas of the corn belt, where cost of hybrid seed is high relative to the value of the expected crop, and in areas where hybrid corn might not be a feasible approach for other reasons, made it seem a worthwhile objective for study. Effort has been made in recent years to increase the productivity of hybrid combinations through selection of new superior lines using standard breeding procedures. The limited progress realized has resulted in an increased interest in the possible use of alternate methods for the development of superior germplasm …

Pollination Cycles And Pollen Dispersal In Relation To Grass Improvement, Melvin D. Jones, L. C. Newell

Nebraska Agricultural Experiment Station: Historical Research Bulletins

The plant breeder is initially concerned with gaining a knowledge of the breeding behavior of his plant materials in order that improvement may be undertaken effectively. It is important to know the different characteristic pollination habits of these plants. To develop and apply techniques applicable to the improvement of a given grass crop, it is desirable to know the time of day and the number of days that the grass sheds pollen. The effects of temperature, humidity, light, and wind on pollination must be considered. Once superiority of germplasm is obtained, the most important consideration is the maintenance of this …
