While it's true that not all rural population is in farming, it's also simplistic to look at just per acre crop yields alone.
Since the Green Revolution in 1960s and 1970s, Pakistan's rural economy has become more diverse with the poultry revolution followed by the ongoing livestock revolution and the entry of big food processing giants serving the growing supermarket chains and the FMCG sector in Pakistan.
Among other basic food commodities, per million population wheat consumption in Pakistan is 115,000 metric tons versus 63,000 metric tons in India, according to published data.
According to the FAO, the average dairy consumption of the developing countries is still very low (45 kg of all dairy products in liquid milk equivalent), compared with the average of 220 kg in the industrial countries. Few developing countries have per capita consumption exceeding 150 kg (Argentina, Uruguay and some pastoral countries in the Sudano-Sahelian zone of Africa). Among the most populous countries, only Pakistan, at 153 kg per capita, has such a level. In South Asia, where milk and dairy products are preferred foods, India has only 64 kg and Bangladesh 14 kg. East Asia has only 10 kg.
While it remains very low by world standards, meat and poultry consumption has also increased significantly in Pakistan over the last decade. Per capita availability of eggs went from 23 in 1991 to 43 in 2005, according to research by N. Daghir. Per capita meat consumption in Pakistan now stands at 12.4 Kg versus India's 4.6 Kg.
