The Case of India 107 



number of farm plans adopted, amount of credit disbursed, num- 

 ber of credit societies, fertilizer used, and area, production, and 

 yield of principal crops. They also recommend administrative and 

 other reforms to improve implementation of the program at each 

 stage. They do not, however, provide economic evaluations in a 

 cost-benefit or comparative sense. 



Dorris Brown's study covered the period of the first five years 

 of the program. He utilized two measures of change in his 

 evaluation: 



1. Compound rates of growth of production, area, and yield 

 levels of all crops from 1956-57 to 1965-66 in each district in 

 the country. 



2. "Indices of change," comprising the quotient of the average 

 value of these variables during the lADP period (1961-66), 

 divided by that in the previous five years. 



His results showed that only three of the fifteen districts re- 

 ported significantly higher rates of change in output and yield for 

 foodgrains during the lADP period when compared with the pre- 

 vious five years. Only two lADP districts reported significantly 

 higher changes in outputs of foodgrains than did bordering dis- 

 tricts, but cultivators in IAD? districts did somewhat better with 

 increased output of cash crops. These data led Brown to conclude 

 that the lADP program did not have an impact on growth in out- 

 put or on growth in yields per hectare. Nonetheless, he offered a 

 strong defense of the program in terms of improvements in input 

 markets and of increased use of modern inputs. He also claimed a 

 somewhat more rapid adoption by lADP farmers of the new 

 Green Revolution technology, but had little data to offer. 



Toward an Improved Specification 



The rate of measured total factor productivity growth in a district 

 is determined by: 



I. The application by producers of new economically relevant 

 technology that originates from three sources: 

 a. Discovery activity directed toward producing technology 

 suited to use under the soil, climate, and economic condi- 

 tions of the district
