Since then many important developmental activities have been taken place in this process but some of them were not up to the mark. By keeping in this view, the Raita Samparka Kendras were started in 2000 to cater the needs of farmers in all aspects of farming. This has given an opportunity to extension worker to perform their works more effectively. In this context, it is worth while to know the attitude of extension personnel towards functioning of Raita Samparka Kendras to make the system more effective.

Considerable quantity of seed tubers used for planting will be saved transportation of seed from one place to another will become easy and inexpensive. Storage losses of seed tubers will be eliminated. Degenerative diseases transition through TPS is less as compared to seed tubers. It is well known fact that the qualitative attributes influence the quality of tubers. Many TPS genotypes have been released in India for cultivation and their quality and behaviour in relation to time of planting is not available. Hence, the present study was undertaken.

The agricultural production not only depends onthe availability of the sustainable technologies, but by various amalgam of factors. Hence, the present study was undertaken to unearth the extension factors influencing the adoption level of sustainable sugarcane farming practices by farmers.

Post-harvest technologies have assumed greater importance in recent years with the increased production due to introduction of high yielding varieties and the adoption of new production technologies. There is sizeable loss of foodgrains in quantity and quality due to inadequate storage facilities in the country (Reddy, 1988).

Education is a means to enhance human resource an.d upgrade standards of living. In a country like India where agriculture is the predominant occupation, agricultural education is very vital to bring about revolution in the rural scenario of the nation. Twenty eight State Agricultural Universities (SAUs), one Central Agricultural University .and four deemed Universities in India have taken up the responsibility of imparting agricultural education. The quality of education provided by these institutions depend largely on the competency of the teachers imparting agricultural education. Hence, an attempt was made to assess the level of job competence of teachers in an Agricultural University.

It is important to develop high yielding strains of chillies through planned breeding programme. In crop improvement, germplasm serves as a valuable source of base population and provides scope for building up of genetic variability heritability and genetic advance will help in ascertaining the real value of the genotypes to select superior ones.

There is conseqential enhancement of thermal heat capacity of soil which eventuates in faster degradation of organic matter and enhanced availability of plant nutrients in the soil (Haynes, 1987). With these in view, a field experiment was conducted at the Agronomy Field Unit,Main Research Station, University of Agricultural Sciences, Bangalore during 1998-99 to study the status of available plant nutrients as influenced by soil solarization. The study comprised of seven treatments consisting of two transparent polyethylenethickness viz., 0.05 and 0.1 mm, three duration of solarization viz., 15, 30 and 45 days during April and May of 1998 and a control. The soil was sandy loam in texture having 6.53, pH, 0.21 d Sm~(-1) of EC, 161.25 kg~(-1) available nitrogen, 33,25 kg ha~(-1) available P_2O_5, 29.45 kg ha~(-1) available K_2O, 10.01 ppm available S, 0.50 me. 100~(-1) g soil of Exch. Ca, 0.21 me. 100 g~(-1) soil of Exch. Mg and 0.14 me 100 g~(-1)soil of Exch. Na. The experiment was laidout in RBD with 3 replications in 4.5x 3.0 m plots. After thorough land preparation, the plots were irrigated to field capacity and the transparent polyethylene sheets of required size were spread on the respective plots depending on the treatments and were sealed at all the sides to makeit air tight with moist soil. FYM 10 t ha~(-1) was incorporated before spreading polyethylene sheets. Soil temperature was recorded using piercing type of mercury thermometer at 5 cm soil depth in both covered and unconvered plots at the end. Soil samples collected from 0 to 15 cm soil depth immediately after solarization were used for the estimation of nutrient status as per Jackson (1973). Similarly exchangable Ca, Mg and Na were analysed by EDTA method as outlined by Jackson (1973.)

It is cultivated both during kharif and rabi looking to the rainfall pattern in the Northern Karnataka. The traditional sorghum growing area mainly comprises medium to deep black soils which suffer from inadequacies of micronutrients like Fe and Zn. Continuous cultivation of high yielding varieties and hybrids with application of only major nutrients without supplementing micronutrients has resulted in decline of productivity in sorghum yield lewis. Of late, response of sorghum to micronutrients has 'been reported in traditionally growing areas (Khapre et al., 1994). Hence, keeping this in view, a field experiment was conducted to study the performance of kharif sorghum to Fe and Zn nutrition.

It is tribal dominated area and in Surguja district their population is 57 per cent. The main tribes of the district are PahariKorwa, Dehari Korwa, Manjhis, Manjhwar, Agaria, Pando and Uraon, etc. (Rajnish 1998). The literacy rate of the district is 23.81 per cent, where female literacy per cent is only 9.67, which is very low as c'ompared to male literacy i.e. 17.11 per cent.These tribes have small farm holding. About 53.6 per cent of holdings are less than 2 ha. and 81.2 per cent holding is less than 5 ha. Similar finding was reported by Jaiswal, 1998. the cropping pattern of the district is basically monocropped and nearly 89 per cent of the total cropped area is allocated under kharif crop of which rice alone constitute about 56 per cent (Anon. 1996).

The establishment of stable permanent microflora in the intestinal tract of fish are reported to takes place gradually with age of fish, type and nature of microbes in food and water, the ability of microbes to combat a variety of extremeconditions and fish defence (Shawn Baskin, 2000). Studies are lacking on the microbial aspects of Indian cultivable carps and their environment (Das and Mukherjee, 1999) Further, information on the colonized microflora of intestinal tract and their enzymatic characteristics are also scanty. There is greater scope to utilize the beneficial intestinal microflora of fish for enhancing growth and survival of younger carps. This communication describes the findings on mean total viable counts (TVC) of intestinal microflora harbouring juvenile common carp (Cyprinus carpio), composition of different bacterial groups to the TVC and enzymatic activities of different microbial isolates.
