Morphological characters, germination percentage and seedling height and other characters were determined. Three sets of 25 seeds in each treatment were germinated at 20°C in three replications on wet blotting paper in petridishes. The data for germination were taken on 5th day and seedling height was measured. for all four concentrations 150, 300, 550, 800 ppm at 8 hrs seed germination percentage was 97.25%,90.12%,93.12%,94.32% respectively. The indices for measuring morphological effects of the Neem, were germination, seedling height, morphological characters (plant height (cm), number of pods per plant , number of seed per pod, leaf length (cm),seed weight (gm) and the number of branches) were analyzed. The study also demonstrates the effects of insecticides on seed germination, seedling growth, morphological characters(plant height(cm), number of branches per plant ,number of pods per plant , length of pods(cm), number of seed per pod, leaf length (cm),seed weight(gm) and the number of branches) , The toxic effects with the biopesticides were comparatively low and generally not significant except at the higher concentration (800 ppm) of neem Biopesticides.
Key words: Faba beans, Biopesticides, Neem, Toxic
