Germplasm from the spring wheat (Triticum aestivum L.) breeding program at the International Center for Improvement of Maize and Wheat (CIMMYT) has had a major impact on the yield of irrigated spring wheats in most developing ...
Interpreting genotype X environment interaction in wheat by partial least squares regression
The partial least squares (PLS) regression method relates genotype × environment interaction effects (GEI) as dependent variables (Y) to external environmental (or cultivar) variables as the explanatory variables (X) ...
The role of conservation agriculture in sustainable agriculture
The paper focuses on conservation agriculture (CA), defined as minimal soil disturbance (no-till, NT) and permanent soil cover (mulch) combined with rotations, as a more sustainable cultivation system for the future. ...
Performance of different wheat genotypes under different tillage options
A field study was carried out at the Regional Wheat Research Center, Shyampur, Rajshahi during Rabi season of 2001-2002 and 2002-2003 to observe the performance of wheat genotypes among the different tillage options. In a ...
Evaluation of three field-based methods for quantifying soil carbon
Three advanced technologies to measure soil carbon (C) density (g C m−2) are deployed in the field and the results compared against those obtained by the dry combustion (DC) method. The advanced methods are: a) Laser ...
Conservation agriculture and soil carbon sequestration: between myth and farmer reality
Improving food security, environmental preservation and enhancing livelihood should be the main targets of the innovators of today's farming systems. Conservation agriculture (CA), based on minimum tillage, crop residue ...
