Evaluation of Tropical Legume Cover Crops for Copper Use Efficiency
American Journal of Plant Sciences
Cover crops are important components of cropping systems due to their role in improving soil quality. Lack of adequate levels of soil micronutrients prevents the success of cover crops in highly weathered tropical soils. A greenhouse experiment was conducted with the objective to evaluate copper use efficiency of nine tropical legume cover crops. The copper levels used were 0, 5, 10 and 20 mg Cu kg −1 of soil. Shoot dry weight, maximum root length and root dry weight significantly increased indoi:10.4236/ajps.2014.59136 fatcat:qfeb5pztvzaaxntie6xga6nqdy
