Description Climate on earth is changing gradually either due to natural processes, extern al fo rcing,. persistent anthropogenic changes in the composition of th e atmosphere or land use.The fourth assessment report of the In te rgovernm en tal Panel on Climate Change (lPCC) con firms that the global average temperature increased by 0. 74°C over the last JOO years and the projected increase in temperature by 2 100 is about 1.8 to 4.0°C. Crop producti vity is projected to decrease even by small rise in temperature ( l-2"C) at the lower latitudes, especially in the seasonal dry and tropical regions. Global warm ing poses a potential th reat to agricultural production and productivity throughout the world and this mi ght affect the crop yields. incidence of '~eeds. pests. plant diseases and the economic costs of
To judge the impacts of climate change on rice phenology and performance in terms of grain and
above ground biomass yield, a field experiment was conducted under semiarid condition of
Kanpur, to know the response of prevailing environments Clnd their interaction wi th
photosensitiw genotypes (mahsoori ) and photoin scn sitivc (/\shwani and Pant - 4). Thi s study
proved that the first year was more fa vorable for growth and development mid the first year crop
produced more biomass. Moreover second year was better for economic produce (grain yield)
probably due to the congenial environmental conditions during reproductive phase. Maximum
thermal time requirements (TTR) were recorded duri ng first year. J\:laximum was for the period
between sowing to till ering ( 1142.4 heat units) under fi rst date of transplanting and minimum
(486.5 heat units) was recorded for period between anthcsis to maturity with last date of
tran splanting. Corresponding maximum thermal time requirements ('!TR) for genotype W
