A Multiple Discriminant Function Approach to Study the Crop Response to Soil Characters (Bengalgram: Crop)

Y.N. Havaldar, K.M.S. Sharma


Multiple group discriminant function approach is carried out to classify the yields of crops in terms of soil characteristics. Four groups in the form of cross-classification of two levels of Nitrogen (low-High) with two levels of Yield (Low-High) was carried out for the purpose, in revealing the relative importance of soil characteristics of practical utility. By using the determinental equation it was seen that λ1 and λ2 together account more than 95 per cent to the total variation. Further it is evident that the variables N.P.K are positively correlated with yield whereas pH of the soil and duration of crop are negatively correlated. Organic carbon and Electrical conductivity of the soil are moderately correlated with Nitrogen and Yield.
