Abstract: Estimation of single, double and triple missing observations are done in agricultural field trials on effect of varieties of Lentil under Relay Cropping with Medium and Long Duration Rice Varieties in split plot set up at District Seed Farm, Bidhan Chandra Krishi Viswavidyalaya, Kalyani, West Bengal for consecutive two years (2014-15 and 2015-16). The missing values are estimated by three methods, viz., Coons (1957), Rubin (1972) and Haseman and Gaylor (1973). Three criteria viz., Absolute Error (AE), Mean Square Error (MSE) and Akaike Information Criterion (AIC) are used to judge the above three methods used for estimation of missing observations. The precision of three methods for single missing observation are same for both the years under study. But, it is observed that precision of Coons and Haseman and Gaylor are equally effective and both are better than Rubin’s method for two and three missing observations. The results are similar for both the years under study.
