It is revealed from the table that co-efficient of multiple determination (R2) of marginal/small, medium and large size group of farms were 0.8162, 0.8111 and 0.8468 respectively. The co-efficient of multiple determination of all four independent variables viz. seed, manure & fertilizer and irrigation and human labour indicate 81.62, 81.11 and 84.68 percent variation in dependent (output) variable in marginal /small medium and large categories of sample farms. The independent variable X4 (human labour) was found statistically significant at 1.00% level of probability in all the categories of sample forms. Similarly the variable X1 (seed) was also found significantly related with output at 1.00% probability level in all cases of farm groups.

Returns to scale (Sum of elasticity) in case of Marginal/ small, medium and large farms were 0.7665, 0.8157 and 0.8242. Which were less than unity. The values of sum of elasticity indicates that the production of wheat is characterized by decreasing returns to scale in all three categories of the farms. It is therefore, inferred that increasing all the Factors by one percent simultaneously increase the return by less than 1 percent and each farm situation.
