Effects of Alternative Seeding Patterns, Seeding Rate, and Seeding Configuration on Yield in a Cotton Production System

With the climbing costs of cotton production, producers must ensure optimal returns on their cotton crops in order to make a profit. The groundwork for a high yielding crop has to start with an accurate and efficient planting system to ensure an optimal stand. However, there are a variety of new systems and techniques to incorporate compared to the conventional system that has been used for so ...

Evaluation of Genotype × Environment Interaction and Determining Grain Yield Stability of Durum Wheat Genotypes in Uniform Regional Yield Trials in Semi-Warm Rainfed Areas

There are different methods for study the genotype × environment interactions and determining stable genotypes such as parametric, non-parametric and multivariate methods. In this research, 19 selective genotypes from advanced trials of durum wheat at 2011-2012 agronomic year, have been cultivated with Dehdasht check cultivar for three growing years (2012-2015) in five locations (including Gach...

Graphical Analysis of Multi-Environment Trials for Barley Yield Using AMMI and GGE-Biplot Under Rain-Fed Conditions

The AMMI and SREG GGE   are among the models that effectively capture the additive and multiplicative components of genotype × environment interaction (GEI) and provide meaningful interpretation of multi-environment trials’ data set in the breeding programs. The objective of this study was to assess the effect of GEI on grain yield of barely advanced lines and exploit the positive GEI effect us...

RICE CULTURE Influence of Row Spacing and Seeding Rate on Grain Yield of Hybrid Rice

Recent interest by producers, researchers, and industry personnel concerning the use of grain drills utilizing 7-in. versus 10-in. row spacing have raised questions as to the optimal drill-row spacing for rice. With the increase in hybrid rice produced and the associated low seeding rates, questions arose regarding the response of these cultivars to row widths. The objective of this study was t...
