Rice and wheat are the staple food of larger part of India’s population and also most important cereal crops of kharif and rabi seasons. The study was carried out on the technological gap in the recommended rice and wheat production system in Purwa and Sumerpur blocks of Unnao district of Uttar Pradesh in 2004-05. A sample of 80 respondents was selected from villages. From each village 10 resource rich and 10 resource poor farmers were selected on the basis of stratified random sampling technique and data were collected with the help of pre-tested interview schedule. The study revealed that majority of resource rich and resource poor farmers did not follow seed treatment in rice. However, for almost all the practices significant number of farmers exhibited partial technological gap. The gaps were least towards nursery management practices like seedbed preparation, weed management and selection of varieties. Regarding rice production practices in main field, resource rich and resource poor farmers did not follow gap filling and in almost all the practices significant number of farmers reflected partial technological gaps. The practices like transplanting distance, harvesting and threshing, use of recommended aged seedlings reflected low gaps in case of most of the farmers. In case of wheat, farmers did not follow plant protection measures whereas more than 80 per cent farmers did not apply seed treatment of wheat. However, for almost all the practices, significant number of both categories of farmers showed partial technological gap in wheat. The practices of wheat like seed rate, harvesting and threshing and selection of varieties showed least gap in case of both categories of farmers
