Abstract

Groundnut (Arachis hypogaea L.) is frequently subjected to drought stress. Pre-treatment of seeds with Chitosan + Trichoderma harzianum (Th4d), polymer1 + Th4d showed significantly greater levels of germination percentage, seed vigor index, soil moisture, shoot fresh and dry weight, relative water content, chlorophyll content, proline content and total sugar levels than Th4d and control treated plants.
