GROWTH AND YIELD ANALYSIS OF BRASSICA-JUNCEA L UNDER 3 PHOTOPERIODS

Growth and development of mustard plant was investigated under different photoperiods. Long day accelerated flowering while short day delayed flowering, including leaf production and reduced plant height. Seeds number per pod and their weight were in the order LD > ND > SD. Increased photoperiod increased NAR, pod number and 1000 seed weight were negatively correlated. In short day while RGR-NAR were negatively correlated, NAR and LWR were positively correlated which was reverse under LD. Prechilling of seeds improved yield under field condition.
