ArticleItem Open Access Changes in IAA levels in rice due to urea-carbofuran interaction(Kerala Agricultural University, 1990) Abdul Salam, M; Subramanian, S; KAUArticleItem Open Access Evidence of Leptospiral Antibodies Among Domestic Animals in Madras City(TANUVAS, 1983) Ratnam, S; Subramanian, S; Sundararaj, T; TANUVASMore number of positive titres were observed in dogs in PUO group 14/20 (70%) than with haemorrhagic enteritis group 6/14 (43%) with higher frequency of antibody to icterohaemorrhagiae (18/27) and canicola (17/27). Goats 8/22 (36%) appear to be more susceptible than sheep 8/38 (21%). The buffaloes were reacting more against tarassovi. Icterohaemorrhagiae appears to be prevalent both in domestic dogs as well as rats, while other strains do not prevail common among all the animals. It appears that different host harbour different strains of leptospires in Madras city.ArticleItem Open Access Immunological Responses to Leptospirosis in Experimentally Infected Buffalo Calves(TANUVAS, 1983) Ratnam, S; Subramanian, S; Adinarayanan, N; TANUVASThe humoral and CMI responses to leptospirosis were studied in experimentally infected buffalo calves. The humoral response to infecting strain (icterohaemorrhagiae, RGA) reached the peak in the second week after infection and then gradually declines. But the CMI response appeared to be specific to the infecting agent in the early days of infection.JournalItem Restricted Journal Of Coffee Research Vol-2(Central Coffee Researc Institute ; Balehonnur, 1972) Subramanian, SArticleItem Open Access Response of rice to azolla inoculation and fertilizer nitrogen(Kerala Agricultural University, 1992) Latha, K R; Subramanian, S; Thangamuthu, G S; Kannaiyan, S; KAUField experiments were conducted to study the effect of fertilizer nitrogen and azolla on yield of rice in Tamil Nadu Agricultural University wetland farm, Coimbatore. Experiments were laid out in a randomised block design with four replications during kharif and rabi, 1984-85. Azolla as dual crop, green manure, different forms of urea like prilled urea (PU), urea super-granules (USG) and neem coated urea (NCU) and their combinations were tried. Azolla biomass production was more in rabi season than kharif. All the forms of urea applied at 75 kg N/ha with and without azolla produced more yield than the control. Plots treated with 25 kg N each as PU, USG and NCU besides azolla as dual crop in kharif and 75 kg N as NCU and azolla as dual crop in rabi recorded the highest grain yield. Dry matter production had the maximum direct effect on grain yield in both the seasons.ArticleItem Open Access Root activity of rice as influenced by zinc application(Kerala Agricultural University, 1987) Abdul Salam, M; Subramanian, S; KAUThesisItem Open Access Studies on the use of baculoviruses for the management of Plutella zylostella (L.) and Spodoptera litura ( F.) infesting cauliflower(Tamil Nadu Agricultural University, 2003) Subramanian, S; Palaniswamy, S
