3.8.1.2 Leaf area and leaf area index (LAI) Leaf area of five randomly selected plants‚ was measured with the help of leaf area meter (Model LI-3100‚ USA) at 20‚ 40 and 60 DAS by destructive sampling from all leaves of the five sample plants (Sticker et al.‚ 1961). Plants were cut at the soil surface‚ leaves were separated from the plants‚ covered with blotting paper to keep the leaf intact and retain its original shape and were brought to the laboratory.
