PERIODIC EFFECT OF COWPEA AND MUNG BEAN PELLETED SEEDS WITH AVICENNIA MARINA (FORSSK.) VIERH PARTS POWDER AND THEIR CONTRIBUTION IN THE CONTROL OF ROOT KNOT NEMATODE
MARIUM TARIQ AND SHAHNAZ DAWAR*
Abstract: Cowpea and mung bean seeds pelleted with Avicennia marina (Forssk.) Vierh parts powder including leaves, stem, pneumatophore were investigated at different intervals of 0 and after 30, 60, 90, 180 and 360 days stored under 4 and 30˚C. Both crops showed improved germination, plant length and plant weight at all storage period upto 360 days but maximum result was accounted upto 90 days interval. Temperature of 4˚C was suitable for storage of pelleted seeds and caused reduction in root knot infection by reducing the number of galls and egg masses per root system in both crops upto 360 days. Leaves and stem powder used as pelletizing material gave better results followed by pneumatophore powder of A. marina. Pyrex (pyrophyllite) had a least effect on germination and growth parameters in contrast to other treatments.
