Description The present study investigates the potential use of a hand-held portable SPAD chlorophyll metre for rapid assessment of specific leaf area (SLA) and specific leaf nitrogen (SLN), which are surrogate measures of transpiration efficiency (TE) in 15 cultivars of peanut (A. hypogaea). The effects of sampling (leaf position, time of sampling and leaf water status) and climatic factors (solar radiation and vapour pressure deficit, VPD) on SLA and SPAD chlorophyll metre reading (SCMR) were studied in a range of peanut genotypes grown under field and greenhouse conditions. Field and greenhouse trials were conducted during the post-rainy (November to April 1997-98) and rainy seasons (July to October 1998) in Andhra Pradesh, India. The correlation between SLA and SCMR was significant (r=-0.77, P
