    Effect of granular insecticides on nodulation, rhizosphere microflora and growth characteristics of cowpea
    (Kerala Agricultural University, 1978) Visalakshy, A; Santhakumari, K; George Koshy; Nair, M R G K
    Studies conducted to assess the effect of ten insecticide granules on nodulation, rhizosphere microflora and growth characteristics of cowpea showed that carbofuran, carbaryl and quinalphos increased the nodules significantly. An increase in size of nodules was also observed by all the insecticides except quinalphos. Carbofuran, carbaryl and chlorodimeiorm increased the plant height. Weight of roots was enhanced by carbofuran and MIPC. The fungal and bacterial population is influenced variously by the different insecticides both in the rhizosphere and non-rhizosphere soil, whereas the actinomycetes population was not affected.

    Effect of phorate on growth characteristics and nitrogen contents of cowpea plants
    (Kerala Agricultural University, 1980) Visalakshi, A; Nair, M R G K
    Studies were made on the effect of phorale applied as granule with seeds treated/untreeted with Rhizobium on growth characterstics and total nitrogen contents of cowpea. In rhizobium treated plants, plant height and root length were significantly increased due to phorate treatment while the other factors such as fresh and dry weights of plants and TNC were increased only at 2 kg ai/ha level. In cowpea plants not treated with Rhizobium the height of the plant and TNC were significantly increased in general by phorate application.
