Abstract: This study assessed morphological variations of Oreochromis niloticus, Sarotherodon galilaeus and Coptodon zilli collected from the Nile and its tributaries. Nineteen morphometric measurements were recorded from each specimen. Data was subjected to discriminant function (CDF) analysis, Wilks' lambda test, t-test and Leave-one-out crosses validation to determine rate of divergence among species. The t-test showed wide variability in the significance (p>0.05 to p0.01) species and site wise in morphometric trait/total length and morphometric trait/head length. The body weight/standard length ratio was consistently significant (p<0.05). Function 1 and Function 2 of CDF clearly separated between O. niloticus and S. galilaeus from Sinnar as well as in Al Sabaloga, and between O. niloticus and C. zilli from Khashm El Girba as revealed by the high significance of Wilks lambda (p<0.003, p<0.000 and p<0.000, respectively). Based on 19 morphometric traits Leave-one-out reclassified the cross validated group at 66.7% and 84.6%, O. niloticus and S. galilaeus from Sinnar, respectively. From Al Sabaloga it reclassified O. niloticus at 97.9% and S. galilaeus at 0.0% due to its small sample size. In Khashm El Girba the cross validated group reclassified O. niloticus at 100% and C. zilli at 94.4%, respectively. Comparison between the values and variables clearly reduced the overlap when 3 traits were used instead of 19 traits. Cluster analysis placed S. galilaeus from Al Sabaloga in a separate branch of the dendrogram due to its small sample size.

Abstract: Ambarnath town in Thane district of Maharashtra having industrial zone around it. For the study purpose seven ground water samples around industrial area were selected and analyzed for Total Hardness parameter. Samples were collected from Jan.2013 to June 2013 and analyzed throughout 6 months for Total Hardness parameter. Total Hardness in study area was found between 154 to 256 to mg/l. Total Hardness at all sampling Stations were found below permissible limit of BIS. At sampling station S1 (Kansai Gaon Open well) and S2 (Kansai Hand pump) Total Hardness were found more than acceptable limit by BIS i.e. above 200 mg/l indicates nature of the geological properties of the area with which water have been in contact.

Abstract: The study examined the landuse change using GIS and remote sensing in the northern part of Eleme Local Government Area of Rivers State, Nigeria. Landsat Tm of 1986, 1999 and landsat ETM of 2015 of 30m x 30m resolution were used for the landuse change analysis. Supervised classification was used to classify the imagery into major landuse of thick vegetation, built up area, swamp forest, farmland/sparse vegetation and waterbodies. Normalized Diffrence Vegetation Index (NDVI) was used to measure the status of vegetation health and classify the entire area into less/not vegetation landuse (LNV) and highly vegetation (HV) landuse. The entire study area was gridded into 10m x10m quadrat whereby 7 quadrats were randomly in LNV and 6 quadrats in HV. Findings revealed that thick vegetation reduced by 129.87% while built up area increased by 468.11% between 1986 and 2015. LNV covered 10.46 km2, 12.02 km2 and 17.89 km2 while HV covered 22.44 km2, 20.88 km2 and 15.01 km2 in 1986, 1999 and 2015 respectively.

This study was conducted to evaluate the impact of bio fertilizers namely, Azotobacterine (Azotobacter chroococcum) and phosphorein (Bacillus polymyxa) and mineral N, P and K fertilizers at the rates of 25, 50 and 100% for each fertilizer (from the doses recommended by Ministry of Agriculture) as well as ascorbic acid at the rate of 400 ppm on growth (plant height, number of branches and herb fresh and dry weights/plant), yield (dry weight of sepales/plant and feddan and weight of seeds/plant and feddan) of roselle plants (Hibiscus sabdariffa, L.) under different soils (clay soil at Dar El-Ramad farm, sandy loam and saline loamy sand soil at Demo farm, Faculty of Agriculture) at El-Fayoum governorate conditions. The data obtained showed that, bio and mineral (NPK) fertilizers increased the above characters of roselle plants under different soils of experiment. The maximum increase of these characters was obtained by the treatment clay soil × 100% NPK + biofertilizers × 400 ppm ascorbic acid, followed by clay soil × 50% NPK + biofertilizers × 400 ppm ascorbic acid as compared to saline loamy sand soil × non fertilizer × zero ascorbic acid treatment, although, the differences between these treatments and mineral fertilizer at the rate of 100% NPK alone were insignificantly. Therefore, it is economically and environmentally recommended to inoculate roselle seeds with mixture of Azotobacter + Bacillus and fertilize these inoculated plants with 50% plus 400 ppm ascorbic acid improve the vegetative growth and augment the yield components of roselle plants under clay soil with spraying 400 ppm of ascorbic acid were obtained the best results of this work study.

The field experiment was carried out at the Cotton research Station, Junagadh Agriculture University, Junagadh during Kharif-2015-16, 2016-17 and 2017-18. The results of experiment were revealed that all the nine insecticidal treatments were found significantly superior to untreated control in reducing the larval population in cotton. The significantly lowest larval population was recorded in plots treated with Lambda cyhalothrin 2.5 EC 0.0025% (1.34 larvae) and Deltamethrin 2.8 EC 0.0028% (1.52 larvae). These two insecticidal treatments were significantly superior to rest of the tested insecticides. While in case of green boll damage, the lowest boll damage was found in Lambda cyhalothrin 2.5 EC 0.0025% (4.2%) and Deltamethrin 2.8 EC 0.0028% (4.9%) and there was a significant difference in damage to open bolls and locule at harvest among treatments. The lowest open bolls and locule damage was recorded in Lambda cyhalothrin 2.5 EC (19.07%) and Deltamethrin 2.8 EC (21.28%). The highest seed cotton yield was recorded in Lambda cyhalothrin 2.5 EC 0.0025% (2337 kg/ha) and Deltamethrin 2.8 EC 0.0028% (2296 kg/ha). The present study suggests that the Lambda cyhalothrin 2.5 EC 0.0025% and Deltamethrin 2.8 EC 0.0028% could effectively reduce pink bollworm infestation and lead to
improve productivity of Bt cotton.

The present investigation was carried out to explore the genetic diversity of five Pearl millet genotypes: MGP-02, MGP-09, MG-P74, MGP-104 and MGP-117 for grain yield, days to 50% flowering, plat height, number of nodes, panicle length and panicle girth. Grain yield showed positive and significant/highly significant correlation with panicle length panicle girth, number of nodes and plant height indicating that grain yield can be boost up by improving these characters through phenotypic selection. Further, high PCV and GCV for the traits studied also suggested that theses parameters can be genetically improved through phenotypic selection in the subsequent generations. Comparatively higher heritability along with high genetic advance for grain yield, plant height and panicle length pointed out that these agronomic characteristics were controlled by additive genes and hence can be improved by gene pyramiding through visual recurrent selection from advanced generations.
