EFFECT OF PRESOWING SEED PRIMING TREATMENT USING BOTANICAL LEAF EXTRACT ON GROWTH AND YIELD CHARACTERS IN BLACKGRAM ( VIGNA MUNGO [ L . ] HEPPER ) cv . CO 6

Field experiment was conducted to study the effect of seed priming using botanical leaf extract on growth and yield parameters of blackgram. The seeds of blackgram were given priming treatments viz., priming with 1% various leaf extract and sown along with dry seeds (control) in a field experiment. The results revealed that 1% Prosopis leaf extract primed seeds recorded higher plant height, number of branches per plant, number of leaves per plant, minimum days to 1st and 50% flowering, number of pods per plant, number of seeds per pod, 100 seed weight, seed yield per plant and seed yield per plot compared to control. From the results found that Prosopis leaf extract records the highest seed yield per plant was 5.37g (i.e.) 8.48% increase over the control.
