Biocidal Effect of p-Cresol-p-Hydroxy Benzaldehyde, p-Cresol Salicylaldehyde, Resorcinal Benzaldehyde, o-Cresol-p- Hydroxy Benzaldehyde and m-Cresol-p- Formal dehyde resins on Micro- organisms

ABSTRACT

Studies on biocidal activity of various resins viz. p-cresol-p-hydroxy benzaldenyde, p-cresol salicylaldehyde, resorcinol benzaldehyde, o-cresonsalicylaldehyde, o-cresol-p-hydroxy benzaldehyde and m-cresol-p-formaldehyde were carried out on fungi and bacteria. The biocidal effect of all resins with 500 ppm was maximum on aspergillus niger and Escherchia coli, where as 1000 ppm concentration resulted maximum biocidal effect on aspergillus flavus and staphylococcus aureus. The maximum inhibition zone ranged as 0.7-0.9 mm for A. niger and 1.5-1..8 mm for E. coli under 500 ppm concentration and 0.6 -0.7 and 0.9-1.4 mm under 1000 ppm concentration for A. flavus and S. aureus, respectively.

Effect of Residual Sodium Carbonate Rich Irrigation Water on the Growth, Yield and Oil Production of Lemon Grass

ABSTRACT

Effect of five levels of sodic irrigation water (RSC 0, 5, 10, 15 and 20 mel-1) was tested on three varieties of lemon grass (Pragati, Praman and OD-19) in microplots and it was observed that higher RSC levels decreased significantly the plant height, number of tillers, herb yield, dry matter yield, oil content and oil production as compared to lower levels of RSC. The mean reductions were 25.09%, 42.32%, 37.64% and 37.61% in oil production with RSC 20 mel-1 at I, II, III and IVth harvests over RSC control. Variety Pragati proved best in performance under sodic water irrigation.

Economic Performance of Weaker Section of Rural Community in Dairy Enterprise

ABSTRACT

The results of the study reveal that the maximum milk production to the extent of 11.53% of the total production was in the month of November. The average net income of marginal and small farmers could be recorded as Rs. 5337.38 and Rs. 4186.68, respectively preferring dairy enterprises. The marginal farmers had Rs. 16812.23 per family farm business income and those of small farmers as Rs. 16174.16 per family farm business income.

Attitude of Farm Women towards Indigenous Technology regarding agriculture

ABSTRACT

An effort was made to develop a scale to measure the attitude of farm women towards traditional agricultural practices. For measuring the attitude of farm women towards TAPs, a scale was developed by the investigator in light of the suggestions of the experts. Most of the respondents had favourable attitude towards traditional agricultural practices whereas 6.00 percent of farm women had unfavourable attitude and only 3.33 percent farm women had most favorable attitude towards traditional agricultural practices which indicate that farm women still had still faith in applicability of these generation-old farm practices as these are according to their socio-cultural domain of living, raised by the means of indigenous research. They considered these practices as their part of life, which ultimately reinforces their favourable attitude towards these traditional agricultural practices.
