Limnology of Surinsar lake, Jammu (J&K State): Part I- Protozoa

Zooplanktonic analysis of Surinsar lake, Jammu, during the year 2002-2004, has shown the presence of fifty one species of protozoans belonging to three classes viz. Sarcodina (32 spp), Ciliata (16 spp.) and Mastigophora (3 spp.). Quantitatively, during the year 2002-03, there was dominance of Sarcodina followed by Ciliata and Mastigophra. In the subsequent year viz. 2003-04, the order of quantitative dominance has been observed as Ciliata> Sarcodina and> Mastigophora. Coefficient of correlation(r) of protozoans with various physico-chemical parameters has generally shown insignificant results. The calculated value of ANOVA of various protozoan classes was significant and the means of various classes differed significantly among themselves indicating their significant contribution to total protozoan population

ANOMALIES IN CIRRHINUS MRIGALA, A COMMERCIALLY IMPORTANT FRESHWATER FOOD FISH, FROM GURDASPUR DISTRICT OF PUNJAB

Cirrhinus mrigala, an important Indian major carp and commonly known as Mrigal, is widely distributed in Indian lotic and lentic water bodies and is cultured in ponds in various Indian states. During the survey of deformed fishes, eight specimens of Cirrhinus mrigala, brought and reared in some fish ponds of Gurdaspur district of Punjab were seen at Gumat fish market, Jammu, and have been described for various morphological and vertebral deformities. The deformities, as noticed in the aberrant fish specimens of Cirrhinus mrigala are generally post dorsal and are most probably induced by excessive use of pesticides in agricultural fields in the area resulting in surface and ground water contamination

Factors Affecting Farmers Decision to Join Joint Forest Management Programme in Jammu Division of Jammu and Kashmir

The present study was conducted in purposively selected “East Forest Circle†of Jammu division of J&K. Multistage sampling plan was followed for the selection of respondents. Six forest ranges from East circle having maximum number of Joint Management Programme (JFM)Cs were selected purposively. Twenty four committees, four from each selected ranges of East circle and eight members from each selected JFMC were selected through random sampling technique. The respondents were divided into two groups 1).Treatment group: Eight members from each selected JFMC were selected randomly for the study making the sample size to 192 respondents. 2). Control group: Two villages from each range (12 villages in total) were selected through random sampling technique. From each selected village nine non- JFMC members were randomly selected. Thus, a total sample of 108 non-JFMC members were selected from these villages. Binary regression model was applied to analyze the factors affecting farmer’s decision to join JFM programme. The result of the study showed that family size, area under trees, extension contact and social participation significantly affecting farmer’s decision to join JFM programme

Knowledge Gap of Silkworm Rearers of Jammu Division of Jammu and Kashmir State

The present study was carried out to know the knowledge gap of silkworm rearers of Jammu division with 240 respondents were selected by proportionate random sampling method from three districts, six blocks and 24 villages. The data was collected by using a pretested structured interview schedule and knowledge test. Average age of silkworm rearers was 46.58 years, the average land holding in hectares was .83 and 29.11 percent of silkworm rearers possessed separate rearing shed. The overall mean knowledge score of three districts was 15.36 (± 2.29) with std. error .14756 and the maximum knowledge score was 22 and minimum knowledge score was 9 the difference was 33.21 per cent. Maximum difference was in case of disinfection and disinfectant which was 40.25 per cent followed by 38.57 percent about mulberry and its management and 37.50 per cent respondents about management of late age rearing. Kruskal Wallis test was applied to all the 23 statements and assign the ranks on the basis of chi square and p- value. The statements which were found significant thickness of cuttings of mulberry for propagation chi square value 9.021(.011), feeding requirement (kg/oz) for first instars larvae 7.535(.023), management of the diseases 5.508(.064) and dose of disinfectant used for silkworm rearing room and appliances for one ounce of seed 5.104(.078). All other knowledge statements were non significant

Effect of different modes of zinc fertilization on growth, yield and economics of quality protein maize under rainfed conditions of Jammu

A field experiment was conducted to evaluate the effect of different modes of zinc fertilization on quality protein maize, to assess the response of zinc on growth, yield attributes, yield and nutrient uptake in quality protein maize. The experiment was laid out in a randomized block design and was replicated thrice. The soil of the experimental field was sandy loam in texture, near to neutral in reaction, low in organic carbon, available nitrogen, potassium and zinc but medium in available phosphorus. The experimental results revealed that seeds treated with zinc-sulphate @ 4g zinc per kg of seed + 1.5% foliar spray with ZnSO4 at knee high and silking stage recorded significantly higher growth, yield attributes and yield, which was statistically at par with seeds treated with ZnSO4 @ 4g/kg of seed + 1% foliar spray of ZnSO4 at knee high and silking stage and seed treatment with ZnSO4 @ 2g/kg of seed + 1.5% foliar spray of zinc-sulphate at knee high and silking stage. In terms of economics, the similar treatment (zinc-sulphate @ 4g/ kg of seed + 1.5% foliar spray using zinc-sulphate at knee high and silking) recorded the highest gross returns, Net returns and B: C ratio, which was closely followed by zinc-sulphate @ 4g/ kg seed + 1% foliar spray of ZnSO4 at knee high and silking stage. Hence, seed treatment with zinc sulphate @ 4g/ kg of seed + foliar application of zinc sulphate @ 1.5% emerged as an effective approach in enhancing growth and yield of quality protein maize under rainfed conditions
