Physiological Basis of Yield and its Components in Rapeseed-Mustard with Reference to Photoperiod
Abstract
In genus Brassica biomass as well as yield are influenced by the duration of photoperiod. Long photoperiod (LD) enhanced productivity in B. carinata (cv. BS-2B-84) whereas in B. campestris (cv. Pusa Kalyani) and B. juncea (cv. Varuna) it is favoured by natural day (ND). Short photoperiod (SD) decreased biomass and seed yield. Seed yield in general was found linearly related with biomass, days taken to flowering and number of pods on primary and secondary branches. Any change brought about in these parameters by photoperiods affects the productivity.
