|Title:||Impact of elevated temperature on growth and yield of mustard (cv. Pusa Agrani)|
Singh, S D
|Abstract:||To assess the impact of elevated temperature on Indian mustard (Brassica juncea var Pusa Agrani) green-house based experiment was conducted at Indian Agricultural Research Institute (IARI), New Delhi for which mustard was grown under four temperature treatments i.e. T0 = ambient temperature; T1 = T0 + 1.5 - 2.5°C; T2 = T0 + 2.5 - 5.0°C and T3 = T0 + 5.0 - 6.5°C. Major growth and yield parameters of mustard plants were analysed at different stages of plant growth. Plant height and specific leaf area showed increasing trend at vegetative stage under elevated temperature treatments (T1, T2 and T3) in comparison to ambient temperature, whereas number of branches/plant and leaf area index (LAI) showed decreasing trend. Under elevated temperature treatments yield parameters showed decreasing trend. In comparison to ambient temperature, the economic yield decreased by 7.5, 11.6 and 16.3 % in T1, T2 and T3 treatments, respectively. Among yield parameters maximum decrease was observed for filled grain/pod under elevated temperature treatments.|
