EFFECT OF SEED DRESSING CHEMICALS ON THE SURVIVAL OF RHIZOBIUM SP. AND GROWTH, NODULATION AND GRAIN YIELD OF GREENGRAM AND BLACKGRAM

Abstract

                                When the seed dressing chemicals are used at the recommended levels on seeds of greengram and blackgram, they reduce the rhizobial population on the seed surface. However seeds treated with carbendazim and monocrotophos at the recom mended levels have not only reduce seed borne pathogens and harbouring pest but also significantly enhanced the plant growth, population and grain yield of greengram. and blackgram over the other chemicals and an untreated control.

Key words : SEED DRESSING, GREENGRAM, BLACKGRAM, RHIZOBIUM, SUR- VIVAL, GROWTH, YIELD.
