Abstract
This study aimed to determine whether straw traits can be integrated into multi-trait improvement
of chickpea. Twenty-four improved varieties and one local variety released for high grain yield were
replicated 4-times in a randomized complete block trial in two locations in Ethiopia. Straw of the local
variety was treated with 4% urea on DM basis and the change in nutritive value was used as a baseline
to qualify enhancement of nutritive value as a result of varietal variation. All straw samples were
evaluated for proximate analysis and ME using a combination of conventional nutritional laboratory
analyses and near infrared reflectance spectroscopy. Effect of variety, location and variety×location
interaction on grain yield, straw yield and straw nutritive value was significant (P<0.05). Urea treatment
significantly (P<0.001) improved straw content of CP and ME by 49 and 4%, respectively. The average
exploitable genotypic range was higher than the effect of urea treatment by 8.3 units for CP and 0.35
units for ME. Correlation between grain yield and straw traits was weak in all locations. It is concluded
that there is a possibility to simultaneously improve grain yield and straw traits of chickpea using
appropriate breeding programs. Genetic improvement of the nutritive value of chickpea straw would
provide farmers with a sustainable alternative to urea treatment.
