Thermal requirement of mustard (Brassica juncea) at different phonological stages under Chhattisgarh plain climatic conditions: A review
Author(s): Deepak Lal, GK Das and Pramod Kumar
Abstract: Growth and yield of Brassica species largely depends upon change in environment during crop growth this change in environment can occur through many practices including sowing dates and water availability. For getting higher yield, sowing time of crop needs to be adjusted with suitable agro-climatic environment (Saha and Khan, 2008). Pradhan et al. (2014) reported that there was significant interaction between date of sowing and cultivars with respect to seed yield of mustard. It was concluded that normal or early sowing of Pusa Jai Kisan or Pusa Bold cultivar may be practiced for achieving higher seed yield, radiation and water use efficiency in semi-arid environment of north and north-western part of India. Indian-mustard is much sensitive to climatic variables; hence, climate change could have significant effect on its production. One month delay in sowing from mid of October resulted in 40.6% loss in seed yield (Lallu, et al., 2010). Gill and Bains (2008) observed a linear and positive relation between leaf area development and photosynthetically active radiation (PAR) interception, which leads to higher dry matter production. LAI plays an important role for crop growth based on its interception and utilization of PAR for producing dry matter and with the delay in planting date, the higher mean temperature was experienced during flowering which led to accelerate the decrease in LAI and reduction in the flowering period.
