University of Agricultural Sciences, Bengaluru

University of Agricultural Sciences Bangalore, a premier institution of agricultural education and research in the country, began as a small agricultural research farm in 1899 on 30 acres of land donated by Her Excellency Maharani Kempa Nanjammanni Vani Vilasa Sannidhiyavaru, the Regent of Mysore and appointed Dr. Lehmann, German Scientist to initiate research on soil crop response with a Laboratory in the Directorate of Agriculture. Later under the initiative of the Dewan of Mysore Sir M. Vishweshwaraiah, the Mysore Agriculture Residential School was established in 1913 at Hebbal which offered Licentiate in Agriculture and later offered a diploma programme in agriculture during 1920. The School was upgraded to Agriculture Collegein 1946 which offered four year degree programs in Agriculture. The Government of Mysore headed by Sri. S. Nijalingappa, the then Chief Minister, established the University of Agricultural Sciences on the pattern of Land Grant College system of USA and the University of Agricultural Sciences Act No. 22 was passed in Legislative Assembly in 1963. Dr. Zakir Hussain, the Vice President of India inaugurated the University on 21st August 1964.

    BIOLOGY AND CONTROL OF CLAVICEPS PURPUREA (FR.) TUL. ON MALESTERILE WHEAT AND BARLEY
    (UNIVERSITY OF AGRICULTURAL SCIENCES GKVK, BANGALORE, 1970) PURANIK, SHIVAYOGI BASAYA; MATHRE, DONALD E
    The seriousness of ergot caused by Claviceps purpurea (Fr.) Tul. in male sterile barley and wheat has prompted further study of the biology of this pathogen. For evaluation of various control measures, a technique of Inoculation was developed and involved the removal of the upper 2 - 4 mm of the glumes prior to inoculation with a conidial suspension using an atomizer. Use of this technique resulted in n e a r ly 100% head and floret infection whereas previously described methods resulted in 2 0 - 6 0 % head infection. Studies on inoculation density revealed that maximum infection occurred with 105 or more conidia per ml. Studies on duration of infection period of unfertilized and fertilized ovaries indicated that inoculation during and shortly after anthesis resulted in the highest levels of floret infection Resulted in the highest levels of floret infection. With unfertilized florets, susceptibility declined at 10days and was lost Completely 15days after the initiation of an thesis. Fertilized Ovaries were susceptible right after fertilization. After the ovaries Had been fertilized for 4days susceptibility decreased until no infection Occurred 9days after fertilization .Many chemicals were Screened for their effectiveness in inhibiting germination and growth Of C. purpurea. Benomyl at 10ppm inhibited germination of conidia While growth was completely inhibitedat 20ppm. Under field cond Itions using male sterile barley, 2400ppm benomyl applied three Times just prior to and during anthesis gave some control of ergot. To determine why economy did not give complete control various conentrations of benomyl were applied to florets with the upper portion of their glumes removed which had been previously inoculated with C. purpurea. Using this method, floret infection was reduced from 94% to 11% with 1000ppm benomyl and to 0% ,if a wetting agent such as Triton X-77 or Multifilm Buffer X was used along with 1000ppm benomyl. This Indicated that benomyl must reach the surface of the ovary at or before Infection to be effective since benomyl did not act as an eradicant Against this pathogen.

    COMMUNICATION PATTERNS AND EFFECTIVENESS OF PROFESSIONALS PERFORMING LINKING ROLES IN A RESEARCH DISSEMINATION ORGANIZATION
    (UNIVERSITY OF AGRICULTURAL SCIENCES GKVK, BANGALORE, 1970) JAIN, NEML CHAND; ROGERS, EVERETT M
    The present dissertation consists of two parts: (1) a conceptual framework for studying communication patterns of linkers involved in the process of research dissemination and utilization, and (2) an empirical study of the relationship between communication patterns and effectiveness of some professionals performing Unking roles within a research dissemination organization, an organization designed to facilitate the dissemination and utilization of research results. The Conceptual Framework The main objective of the framework suggested in the present dissertation was to provide a perspective or frame of reference that could facilitate both theoretical and empirical analysis of communication patterns of linkers involved in the process of research utilization. Research utilization is the process by which research results are communicated to, and adopted by, the clients. The three social systems involved in the process of research utilization are research system, Unking system, and client system. The term communication pattern is used to include those communication behaviors of an Individual, dyad, group, or social system that are systematic or exhibit some form of regularity (as opposed to randomness). The two useful levels of analysis for studying communication patterns are the individual level and the dyadic level. At the individual level of analysis, nine categories of communication patterns are formulated. At the dyadic level, the framework suggests six different categories of communication patterns. The categories of communication patterns relevant for studying the communication behavior of linkers are: communication patterns dealing with (1) information Input behavior of linkers, (2) Information-processing behavior of linkers, (3) Information output behavior of linkers, (4) communication between linkers and researchers, (5) communication between linkers and clients, and (6) communication among linkers. The framework concludes with some examples of concepts and research questions (underlying each of the six categories of communication patterns) that are relevant for studying communication patterns of linkers. T h e Empirical Study The empirical study reported in the present dissertation was designed to test eight hypotheses about the relationship between the communication patterns and peer-evaluated effectiveness of linkers working in a research dissemination organization, the Michigan Cooperative E x tension Service. Eight communication pattern variables hypothesized to be positively related with the c o m m o n dependent variable of peerevaluated effectiveness are: (1) Information Input amount, (2) information Input diversity, (3) peer-communication amount, (4) peercommunlcatlon diversity, (5) linker network centrality, (6) opinion leadership, (7) Information output amount, and (8) information output diversity. The field survey design was used In the present study. The sample consisted of fifty specialized linkers (or Extension Specialists) selected from seven academic departments of the Michigan State University. Most of the data was collected from Individual specialists by personal Interviews supplemented with s ome pretested and structured Interview schedules and self-administered instruments. The data about the biographical Information and the Information output activities of the specialists were collected from organizational records. Partial correlation technique was used to control statistically the effect of four variables—age, organizational status, professional experience, and project leadership, on the hypothesized relationships. Of the eight hypotheses in the study, four were supported by our data. The communication pattern variables positively correlated with the peer-evaluated effectiveness of linkers (at the .05 level of significance) are (1) peer-communication diversity, (2) linker network centrality, (3) opinion leadership, and (4) Information output diversity. The other four communication pattern variables, Information input amount, information input diversity, peer-communication amount, and Information output amount, vere not found to be significantly related to the peer-evaluated effectiveness of linkers. One general observation from our findings is that the communication pattern variables dealing with the ’diversity" aspect of linkers' communication behavior tend to be more often correlated with the effectiveness of linkers than are the variables dealing with the "amount" aspect of linkers1 communication behavior.
