Delineation of thermal requirements of rice (Oryza sativa L ) using geospatial technology in Punjab

Under field conditions, temperature influence on development and yield of crop plants is studied through accumulated heat unit system as plants have a distinct temperature requirement prior to the attainment of certain phenological stage. A study was therefore planned to find out the heat unit varia...

Description
Summary:Under field conditions, temperature influence on development and yield of crop plants is studied through accumulated heat unit system as plants have a distinct temperature requirement prior to the attainment of certain phenological stage. A study was therefore planned to find out the heat unit variability in rice due to climate change on Spatio-temporal scale usingArc GIS 10.2. Long term (1990-2019) district-wise climate data (maximum and minimum temperature) during the rice growing season (June to October) was collected from Department of Climate Change and Agricultural Meteorology, Punjab Agricultural University (PAU) Ludhiana, India Meteorological Department and different websites.
