Abstract

Wang, H., Gan, Y., Brandt, K., He, Y., Qin, X. and Li, Z. 2015. Can surface residue alleviate water and heat stress? Can. J. Plant Sci. 95: 197-200. Surface-placed residue increased the near soil surface moisture and reduced root heat stress. The improved micro environment resulted in greater root length for wheat (Triticum aestivum L.) and canola (Brassica napus) and 34, 8 and 8% higher yield, 7, 52 and 20% more straw and 7, 5, and 7.5 cm taller than the non-residue check for wheat, canola and dry pea (Pisum sativum), respectively.
