    Varietal response to rhisobium inoculation in cowpea under field conditions
    (Department of Plant Pathology, College of Agriculture, Vellayani, 1983) Beena, S; KAU; James Mathew
    An investigation was undertaken at the Research Station, Kayamkulam during the summer season of 1981-82 to study the varietal response to Rhizobium inoculation in cowpea under field conditions. Ten varieties of cowpea C-152, ptb-1, Pusa-2, Hg-22, 522, 533, 534,551, 779 and V-37 were used in this experiment. The rhizobius strain 6050 was used for the innoculation.

    Standardisation of top working in nutmeg (Myristica fragrans Houtt.)
    (Department of Plantation Crops and Spices, College of Horticulture, Vellanikkara, 1994) Beena, S; KAU; Alice, Kurian
    The present investigations on “Standardisation of top working in nutmeg (Myristica fragrans Houtt.)” were conducted at the Department of plantation Crops and spices, College of Horticulture, Vellanikkara, Thrissur during 1991-1993. For the purpose of the study nutmeg trees available at state seed Farm, Mannuthy and farmers’ field at Mannuthy and Ettumuna in Thrissur district as well as Neduvannur in Ernakulam district were utilized. The presence of two type of buds on the bud stick could be distinguished by the bud scare at the inner side of the bark for the viable buds and absence of scar and browning in the non- viable buds. Among the difference methods tried, in situ budding on hard trunk proved to be most successful. Forkert method with bud selected from brown bud wood with fallen leaves and the buds inserted by leaving space on all the four sides gave maximum success. In order to achieve a quicker bud burst stumping the plants two months after budding was most effective. Budding on hard trunk could be done with maximum success in three year old plants and July was found to be the best season. Trials on topping of male trees indicated that heading back the tree above the first tier during August was found to be the best with regard to sprout production and reducing the time for sprouting. Forkert budding on new sprouts gave only initial success which failed to sprout even with physical and chemical treatments. Grafting on new sprouts showed least response among the method tried. Successful graft union was obtained during March with scion shoots having mature leaf and full green stem and stock having two months growth. The anatomical studies revealed low callus development and sparse differentiation of vascular tissues in the bud shield, presence of necrotic tissues hindering the formation of callus and the lack of union between old and new callus as the probable reasons for bud failure.

    Performance and potential of gramasabhas in crop production in Athiyanoor block of Thiruvananthapuram district
    (Department of Agricultural Extension, College of Agriculture, Vellayani, 2002) Beena, S; KAU; Sherief, A K
    The study entitled 'Performance and potential of gramasabhas in crop production. in Athiyanoor block of Thiruvananthapuram district was undertaken to study the effectiveness, attitude and perception and to identify the constraints as perceived by the farmers, officials and people's representatives regarding the functioning of gramasabhas. The study was conducted in Venganoor, Vizhinjam, Athiyanoor and Kottukal panchayats of Athiyanoor block. A sample of 200 respondents were selected using multistage random sampling technique. Data were collected through well structured and pre-tested interview schedule. Sixty per cent of the farmers, fifty five per cent of the officials and sixty per cent of the people's representatives perceive the gramasabhas as effective in planning and implanting agricultural development programmes. Regarding the attitude towards gramasabhas, 58.43 per cent of the farmers and 87.50 per cent of the people's representatives possessed a very favourable attitude. Among the officials, 65 per cent were favourable towards gramasabhas. Eighty per cent of the people's representatives had very good perception about the functioning of gramasabhas. The study revealed that 57.50 per cent of the officials and 61.67 per cent of the farmers belonged to high group with respect to perception. Majority of the farmers had education upto high school level with farming as the main occupation. Most of the farmers expressed a high level of political orientation, cosmopoliteness, social participation and extension participation. Information source utilisation and orientation of the farmers towards incentives were also found to be high for majority of the respondents. Personal, socio-psychological variables viz., education, political orientation, cosmopoliteness, social participation, information source utilisation, leadership propensity, attitude towards people's plan and orientation towards incentives had shown a positive and significant relationship with effectiveness. Annual income had negatively significant relationship with effectiveness. Education, main occupation, political orientation, social participation, attitude towards people's plan, economic motivation and orientation towards incentives had shown a positive and significant relation with attitude of the farmers towards gramasabhas. Annual income was found to be negatively correlated with attitude. Education, main occupation, political orientation, social participation, attitude towards people's plan, economic motivation and orientation towards incentives had shown a 'positively significant relationship with perception of the farmers about. the functioning of gramasabhas. Annual income had negatively significant relation with perception. Venganoor and Kottukal panchayats differed significantly with respect to leadership propensity. The respondents of Venganoor panchayat had high level of leadership propensity as compared to those in Kottukal panchayat. Venganoor and Kottukal panchayats differed significantly with respect to perceived effectiveness. The respondents in Venganoor panchayat perceived the gramasabhas as highly effective in planning and implementing agricultural development progarammes. There was no significant difference among Venganoor, Vizhinjam, Athiyanoor and Kottukal panchayats with respect to attitude and perception about the gramasabhas. The officials and the people's representatives exhibited non- significant relationship regarding the perceived effectiveness of gramasabhas in planning and implementing agricultural development programmes. . As far as attitude towards gramasabhas is concerned, the officials and the people's representatives differed significantly.

Significant difference was observed between the officials and the people's representatives regarding the perception about the functioning of gramasabhas.
