Research ArticleOpen accessIn the abstractContribution of Primary Spikes Vs Tillers to Total Deoxynivalenol in Harvested Grain of Wheat and BarleyPravin Gautam, Scott Halley, Jeffrey M. SteinFormation of higher number of tillers is desirable for higher grain yield in both wheat and barley; tillers have delayed physiological development. Studies addressing the contribution of secondary tillers in final DON concentration for wheat and barley are limited. This project aims to improve our understanding of the relationship between FHB symptoms and DON concentration by examining the contribution of … …American Journal of Agricultural and Biological Sciences, Vol. 7, Issue 3 · 25 Jul 2012 · 7,912 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Effect of Rumen Acid Load on Postpartum Performance and Blood Metabolic Responses in Transition Holstein CowsSadjad Danesh Mesgaran, Alireza Vakili, Alireza Heravi Moosavi, Ghasem KoolabadiProblem statement: The transition period is the most stressful time in the production cycle of a dairy cow because of depressed feed intake, endocrine and metabolic changes at parturition. The aim was to determine the effect of rumen acid load on postpartum performance and metabolic parameters in transition Holstein cows. Approach: The Acidogenicity Values (AV) of the diets were determined … …American Journal of Animal and Veterinary Sciences, Vol. 6, Issue 1 · 25 May 2011 · 7,438 accessesView PDFCite

Sub plots consisted of combined application … …American Journal of Agricultural and Biological Sciences, Vol. 5, Issue 2 · 30 Jun 2010 · 8,484 accessesView PDFCite
Research ArticleOpen accessIn the abstractMultienvironment Analysis of Traits Relation and Hybrids Comparison of Maize Based on the Genotype by Trait BiplotSaeed Safari Dolatabad, Rajab Choukan, Eslam Majidi Hervan, Hamid DehghaniProblem Statement: The Genotype by Trait (GT) biplot can be used to compare cultivars on the basis of multiple traits and to identify cultivars that are particularly good in certain traits and therefore can be candidates for parents in plant breeding program. Approach: The objective of this study was to evaluate the maize hybrids based on Genotype by Traits (GT) … …American Journal of Agricultural and Biological Sciences, Vol. 5, Issue 1 · 31 Mar 2010 · 9,234 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffect of Potassium Levels on Antioxidant Enzymes and Malondialdehyde Content under Drought Stress in Sunflower (Helianthus annuus L.)H. Soleimanzadeh, D. Habibi, M.R. Ardakani et al.Problem Statement: Drought stress as a major adverse factor can lower leaf water potential, leading to reduced turgor and some other responses and ultimately lower crop productivity in arid and semi arid zones. Sunflower is one of the main oil seed crops in Iran, where drought stress is the most limiting factor. Drought stress tolerance requires the activation of complex … …American Journal of Agricultural and Biological Sciences, Vol. 5, Issue 1 · 31 Mar 2010 · 10,779 accessesView PDFCite

Research ArticleOpen accessIn the abstractCompetition Effects of Date of Sowing and Nutsedge Removal Time on Yield and Yield Contributing Characters of Tef [Eragrostis tef (Zucc.) Trotter]Abdul Shukor Juraimi, Mahfuza Begum, Ahmed Mohammed Sherif, Anuar Abdul RahimProblem statement: Tef [Eragrostis tef (Zucc.) Trotter] is a C4 grass, most important indigenous cereal crop in Ethiopia. The average grain yield of this crop is low; averaging <0.8 Mg ha-1. Under appropriate cultural practices such as the right sowing date, sowing rate, weeding time and fertilizer application, tef could produce grain yields of 2200-4599 kg ha-1.

Research ArticleOpen accessIn the abstractEffects of Grazing Sorghum Stubble on Soil Physical Properties and Subsequent Crop PerformanceB.J. Radford, D.F. Yule, M. Braunack, C. PlayfordTwo grazing trials were conducted on a Vertosol in central Queensland to assess the effects of stubble grazing by cattle on soil properties and subsequent crop performance. Two adjacent contour bays were selected for two treatments (grazed and ungrazed) in each trial. Both trials were conducted following a grain sorghum crop. In trial 1 (during 1996) the surface soil was … …American Journal of Agricultural and Biological Sciences, Vol. 3, Issue 4 · 31 Dec 2008 · 8,154 accessesView PDFCite
Research ArticleOpen accessIn the abstractCompressive Load Resistance Characteristics of Rice GrainSumpun Chaitep, Chaiy Rungsiyakull, Pipatpong WatanawanyooInvestigation was made to observe the compressive load property of rice gain both rough rice and brown grain. Six rice varieties (indica and japonica) were examined with the moisture content at 10-12%.
