(Texas A&M University. Libraries, 1989)Genetic parameters are associated with corn kernel characteristics were estimated using parent/offspring regressions, variance components analyses and the intra-class correlations of half-sibs. The experimental and mating ...
-
(2009-06-12)This publication explains how to estimate the grain yield of a corn crop before harvest. An interactive grain yield calculator is included. 6 pages, 3 tables, 1 figure.
-
(Texas A&M University. Libraries, 1980)The effect of soil moisture, soil temperature and soil pH on sorghum downy mildew (SDM) disease incidence (DI) was evaluated. In the field, when sorghum and maize hosts were planted at different dates during the cropping ...
-
(Texas A&M University. Libraries, 1980)Ultrathin sections of tissues, organs, and whole bodies of black-faced leafhoppers, Graminella nigrifrons (Forbes), were examined by transmission electron microscopy. Virions were observed adsorbed only to the intima of ...
-
(Texas A&M University. Libraries, 1990)A technique was developed to expose corn seedlings to EPTC, a volatile herbicide, or CGA-136872, a non-volatile herbicide. This technique was used to document the cross tolerance of a CGA-136872-tolerant variety, Funk ...
-
(Texas A&M University. Libraries, 1982)Pecan leaf surfaces were characterized in relation to tree age, leaf age, and leaf surface. Three types of trichomes were found. Awn-like hairs were the most common trichome type on juvenile trees and reached their greatest ...
-
(2006-05-24)Insect pest control procedures are discussed for each stage of crop development. The characteristics of individual pests, economic thresholds and specific recommendations for chemical control are presented, including ...
-
(2012-10-19)For more than thirty years, studies about the effect of the exchange rate on exports have been conducted. However, few have considered the combined effect of the exchange rate on imported inputs into the agricultural system ...
-
(2009-05-15)Aspergillus flavus is a fungus pathogen of maize that causes contamination of maize with aflatoxin. Aflatoxin is a carcinogenic toxin that can cause harm to human and animal health. Several management practices have been ...
-
(Texas A&M University. Libraries, 1988)Changes in the structure, physical and physico-chemical properties of corn and sorghum during nixtamalization and production of tortillas were documented using a combination of masa fractionation, x-ray diffraction, ...
-
(Texas A&M University. Libraries, 1993)The effects of two sodium chloride (NaCI) stress protocols, salt acclimation (sa) and salt shock (ss), on growth, water relations, and the contribution of inorganic and organic solutes to osmotic adjustment were studied ...
-
Prevention of reproductive failure in maize plants at low water potentials by stem tissue infusion (Texas A&M University. Libraries, 1989)A delivery method for rapid external supply of dilute or concentrated doses of water soluble materials to maize plants was developed. The route of access is through a small cavity prepared in the stem which acts as an ...
-
(Texas A&M University. Libraries, 1977)ADPGlucose pyrophosphorylase A was purified 126-fold to homogeneity from maize endosperm. The molecular weight estimated by gel filtration was 375,000 and 400,000 by disc acrylamide electrophoretic techniques. SDS disc gel ...
-
(2008-04-30)Corn and grain sorghum producers who use atrazine herbicide will be interested in the results of this study of three application methods--the conventional broadcast method, the preplant incorporation method, and the banding ...
-
(Texas A&M University. Libraries, 1989)Ultrastructural comparisons of aleurone tissues from wild type, vp/vp and vp5/vp5 maize kernels were made at 16, 25 and 35 days after pollination (DAP). Wild type and vp5 aleurone cells were similar at 16 and 25 DAP, but ...
-
(Texas A&M University. Libraries, 1987)The objectives were broad in scope, but they centered around the theme of disease resistance. In Chapter 2, the techniques used in evaluating the general resistance (pustule density and AUDPC) were shown to be efficient. ...
-
(Texas A&M University. Libraries, 1985)There have been many investigations into the time interval when yield is most susceptible to stress. Knowledge of this interval is important to understanding yield potential, for modeling, irrigation scheduling, and the ...
-
(2018-08-16)Grain yield is a trait of economic importance to farmers and agricultural industries. There has been much research at molecular and genetic levels to improve grain yield, but environmental factors can be equally or more ...
-
(1999-10-07)Atrazine is the most widely used herbicide in Texas corn and grain sorghum production. It is also used in lawn products. Atrazine can run off the site of application and enter surface water if applied incorrectly, but it ...
-
(2002-02-19)Weeds can be controlled in corn through cultural, mechanical and chemical means. This publication suggests ways of controlling weeds culturally and mechanically, and also lists herbicides with suggested application times ...
