    Studies on Fungal and Bacterial Endophytes of Soybean (Glycine max (L.) Merrill) Against the Soilborne Pathogens
    (University of Agricultural Sciences, Dharwad, 0200) Brunda, K.S.; Jahagirdar, Shamarao
    A total of 30 fungal and 30 bacterial endophytes were isolated from healthy soybean plants during kharif 2017 from major soybean growing areas of northern Karnataka viz., Belagavi, Haveri, Bidar, Dharwad and parts of Maharashtra viz., Kolhapur and Sangli districts. Maximum number of endophytes were obtained from Belagavi district (21) followed by Dharwad district (15). Mean maximum endophyte association was observed in irrigated condition (1.38 for fungal and 1.63 for bacterial endophytes), black soil (1.31 for fungal and 1.46 for bacterial) and at vegetative stage (1.73 for fungal and 1.27 for bacterial). In dual culture method of screening, the endophytes RF-BV-3, SF-DM-8, RB-KK-6, SB-BS-6 and LB-BU-1 were effective against Sclerotium rolfsii and the isolates SF-DM-8, SB-DG-11 and LB-BiN-8 were effective against Rhizoctonia bataticola. The effective endophytes against Fusarium oxysporum were RF-BV-3, SF-BV-3, SF-DM-8, SF-DS-10, LF-HH-5, LF-DM-10, LF-DD-13, LF-KK-14, RB-HS-1, SB-BiJ-9, LB-BU-1 and LB-BV-2. Based on cultural, morphological and molecular methods, the effective fungal endophytes were identified as Daldinia eschscholtzi (RF-BV-3), Fusarium solani (SF-BV-3 and LF-KK-14), Neofusicoccum parvum (SF-DM-8), Diaporthe phaseolorum (SF-DS-10 and LF-HH-5), Phomopsis sp. (LF-DM-10) and Colletotrichum aenigma (LF-DD-13). The effective bacterial endophytes were identified as Acinetobacter sp. (RB-HS-1), Alcaligenes faecalis (RB-KK-6), Stenotrophomonas sp. (SB-BiJ-9), Bacillus pumilus (SB-DG-11 and LB-BiN-8), Paenalcaligenes sp. (LB-BU-1), Bacillus cereus (SB-BS-6) and Brevibacillus sp. (LB-BV-2). Under glasshouse studies, SF-DM-8 was effective against all the three pathogens (less disease incidence of 21.88 % against S. rolfsii, 27.50 % against R. bataticola and 25.00 % against F. oxysporum) and showed enhanced growth promotion activity (increased plant height, leaflet number etc.) with maximum disease incidence of 100 per cent in untreated check. The endophyte RB-KK-6 was effective against S. rolfsii with less disease incidence (31.25 %). The endophytes RF-BV-3 and SB-BiJ-9 were effective against F. oxysporum with minimum disease incidence of 16.67 per cent.

    EMOTIONAL COMPETENCE AND FAMILY ENVIRONMENT OF SCHOOL CHILDREN (13-15 YEARS)
    (University of Agricultural Sciences, Dharwad., 01-06-14) Banrisha S. Basaiawmoit; Dr. Saraswati C. Hunshal
    A study on the emotional competence and family environment of school children (13-15 years) was undertaken in the year 2013-14. The sample for the study included children in the age of 13-15 years who were studying in 8th and 9th standards from different schools located in two cities i.e. Dharwad and Shillong of Karnataka and Meghalaya states respectively. Two schools were randomly selected from each cities, one government and a private school. Total 160 school children were selected, out of these 80 were selected from Shillong city and 80 from Dharwad city, Emotional competence scale by Bharadwaj and Sharma (1995) was used for measuring emotional competence, Family environment scale by Bhatia and Chadha (1993) was used to assess family environment and sociometric technique was employed to see the peer status of the school children. The results of the study revealed significant difference between Dharwad and Shillong children in the overall emotional competence where Dharwad children had better emotional competence. It was also noticed that peer accepted children had better emotional competence than peer rejected children. In case of family environment dimensions between Dharwad and Shillong children, significant difference was observed in dimensions such as cohesion, expressiveness, acceptance and caring and organization. Also family environment dimensions such as cohesion, expressiveness, acceptance and caring and organization had significant influence on overall emotional competence. The study findings also showed that emotional competence improved with age. The study also revealed that boys had better emotional competence than girls. Familial factors such as parent’s education, income, socioeconomic status and family size were significantly associated with overall emotional competence. Private school children were better in emotional competence compared to government school children.
