Abstract


Crop establishment is the first step and one of the most important stage in the vegetative cycle of sunflower plants. Uneven emergence and low stand density will compromise the subsequent stages of growth, limiting potential yield and economic outcome under varying climate and soil conditions. However, seed enhancement technology could be better approach towards mitigation of above stated problem. The objective is to see if the improved stand establishment, vigour and biochemical traits could be corelated with seed priming and coating techniques in sunflower. Thus, an experiment was conducted including seed priming, coating and combination. The treatments selected for that purpose were hydropriming, priming with moringa leaf extract, priming with magnetic treated water, seeds treated with combination of magnetic treated water and moringa leaf extract, seed coating with CaO (8g CaO/20g seed) and seed coating with moringa leaf powder (7g MLP/20g seed). All the experimental units having primed and coated seeds were compared to control seed (non-primed and un-coated). Results of experiment shows a significant improvement in stand establishment of treated seeds as compared to control. Final emergence percentage of seed primed with a combination of moringa leaf extract and magnetic treated water increased to 21% as compared to control. Though all seed enhancements show a tremendous increase in seedling growth however maximum growth was observed in seed treated with moringa leaf extract and magnetic water followed by seeds coated with CaO.  Increased plant height, yield and yield related attributes in primed and coated seeds was linked with high vigour and health of sunflower thereby better survival in changing climatic and soil conditions. Our finding suggests that seed priming with a combination of moringa leaf extract and magnetic water also seed coating with CaO could be helpful in solving the problem of decreased plant population and improved vigour to overcome incompatible soil and environmental conditions.
