Inter-Size Crop Level Agricultural Production Function With Reference To Groundnut Crop: A Case Study in Nellore District Of Andhra Pradesh

Abstract

Crop-wise production function analysis will clearly indicate many points which are not evident in aggregate and size-wise models. But crop-wise analysis is a farm of aggregate model as the output of a crop coming from different size enterprises has been put together. Land is an important factor for production and its effect on technology must be fully emphasized. It is only an inter-size analysis of production function for a particular crop, which can do away the limitations of an aggregate crop model. Inter-size crop models would also indicate the relative superiority of different crops for different size-group of farms that it is helpful for crop-cum-size level planning. The study aims to analyse the Inter-size crop level Agricultural Production Function for staple crop-groundnut based on entire sample of farms in Three Revenue Mandals of Nellore District, Andhra Pradesh. Data was collected for the explanatory and explained variables with the help of survey method through personal interviews of the farmers selected through mixed sampling in three revenue mandals of Nellore district. Regression co-efficients are estimated to study the relationship between gross output and various factors of production. The sum of the elasticities and their statistical significance was also studied to decide the returns to scale.
