| Abstract:
To evolve criteria for selection of quality seedlings in cashew a preliminary study was taken up. The dry weight of the seedlings is taken as a measure of its vigour. To evolve a non-destructive and easy method of estimating the total dry weight, correlations were worked out between the total dry weight, total leaf area and total leaf weight besides the individual leaf area and individual leaf weight. Total leaf area is highly correlated with the total dry weight. A simple prediction equation was derived to estimate the total leaf area based on the linear measurements of 2nd and middle leaf and the total number of leaves. The coefficient of predictability of leaf area based on this equation was found to be very high (90 – 94%). | |
