1971 female data were not taken from 1971 census counts 

 because of inconsistent definitions between 1961-71. 

 Female growth rates between 1961 and 1971 were 

 assumed to be the same as the actual growth rates in the 

 male labor-force. The numbers of days worked per year 

 by male and female cultivators and laborers, from Fact 

 Book on Manpower (N.S.S. data), were used to correct num- 

 bers of laborers into numbers of days worked. Separate 

 growth rates between censuses for males and females 

 were computed. 



3. Factor-share data were computed, using the following prices: 



a. Land: Rental values of irrigated and unirrigated land were 

 computed from Punjab Farm Accounts annually for 1956 to 

 1970. This series was adjusted by comparison with cash 

 rental data from several Farm Management Studies (sum- 

 marized in C. H. Rao, Agricultural Production Functions, 

 Asia Publishing House, Bombay, August 1965, for early 

 years) and taken from reports for several districts in later 

 years. Andhra Pradesh (1961-62), Bihar (1958-60), Orissa 

 (1958-60), Mysore (1960). Other data from 1959-60 Rural 

 Credit Survey were also used. On the basis of these 

 sources, a determination was made to use the Punjab- 

 Haryana rental rates for irrigated and unirrigated land for 

 the northern states Punjab-Haryana, Gujarat, Rajasthan, 

 U.P. and A. P. An adjustment to 90% of Punjab prices was 

 applied to land in West Bengal, Bihar, and Assam. For re- 

 maining states, the adjustment was 70% of the Punjab 

 prices. These were our best estimates of the comparative 

 prices based on the farm management study data. Irri- 

 gated land was treated on a separate factor and the 

 difference in the rental rates for irrigated or unirrigated 

 land was assumed to reflect public sector as well as private 

 sector investment in canal irrigation. 



b. Fertilizer: Prices for nitrogen, phosphate, and potash 

 from Fertilizer Statistics, Fertilizer Association of India. 



c. Pumpsets: Farm management data from the Punjab were 

 used to compute depreciation maintenance plus operating
