Abstract: wo of the many benefits of including allelopathic plants in suppressing Parthenium hysterophorus L. are decreasing fresh weight and biomass of Parthenium weed. This study was conducted in order to examine the effect of selected plants on fresh weight and biomass in tropical Agra, India. Together with an untreated control plot, Parthenium and selected allelopathic plants were grown from January 2012- December 2012. The weeds were allowed to develop uncontrolled for 3 months until the time when selected allelopathic plants would be planted with Parthenium. In the period after the incorporation of allelopathic plants Parthenium biomass was less, than in control. More than half of the biomass reduced by 15 days after the incorporation of allelopathic plants. The chemical exudates from allelopathic plants are proposed to play a major role in the allelopathy mode of action

Key words: Parthenium, Allelopathic plants, Incorporation, Biomass

Abstract: As a popular fish species Puntius sophore is well known in the market of Asia. It has considerable demand as ornamental fish also. An attractive phenotypic feature made this species beautiful.This species looks nice because of development of a beautiful undulating structure of the dorsal and caudal fins during slow swimming activity. The food search activity of the species looks very good-looking. Knowledge of some particular biological parameters such as reproductive physiology as well as feeding biology of this fish is important in aquaculture view point. For this purpose some particularparameters of reproductive physiology are being studied which have been development of gonads in relation to length and weight, gonado-somatic index, maturity stages related to age, fecundity and breeding periodicity as well. Amongst feeding biology parameters studied have been analysis of some digestive enzymes ( such as pepsin and alpha-amylase) during fingerling and adult stage, growth and development in relation to age, RLG, assessment of condition factor (K) etc.

Key words: Sex ratio, Maturity stages, Gonado-somatic index, Pepsin, Alpha-amylase

Abstract: The present observations revealed that F1 hybrids produced by crossing 10 different rice genotypes with 3 CMS lines behaved differently with regard to pollen fertility. Out of 30 F1 hybrids, 4 were completely sterile and 19 completely fertile. The remaining 7 hybrids expressed varying degrees of fertility within the range of partial restorer. Genotypes viz., BPT-5204, GR-32, CR-2496, MTU-7029 and Type-3 produced higher fertile hybrids and were hence considered as common effective restorers for all the three CMS lines. Kalanamak was found to be an effective restorer for CMS lines, IR58025A and Pusa 6A. Sona Choor was found to be an effective restorer for CMS lines, IR58025A and IR68897A. These restorer genotypes may be further tested for heterosis for development of new rice hybrids. Three genotypes (HUR-105, HUR-3022 and Anjali) produced sterile hybrids when crossed with IR58025A. HUR-3022 produced sterile hybrids, when crossed with Pusa 6A and IR58025A and may be further used for the development of new male sterile lines.

Key words: CMS lines, fertility restorers, hybrid rice, maintainer, wild abortive

Abstract: Studies were undertaken to assess the association and regression of quantitative traits with seed yield of 17 maize inbreds comprising domestic and exotic gene pools. The results revealed that cob length, number of kernel rows, cob weight and 100 seed weight were significantly and positively associated with single plant yield. The other characters viz., days to 50 per cent tasseling, silking, plant height and number of kernels per row were also showed positive correlation with single plant yield (g). The linear models expressed poor regression between seed weight cob-1 and days to 50 per cent tasseling (R2=0.147) and silking (R2=0.160) while it was higher between single plant yield (g) and cob weight (R2=0.930)

Abstract: The effluent discharged from textile and dye industries, breweries, fertilizers were hazardous to the flora and fauna of inland streams or other natural water resources. The discharge of effluent into the river increased the BOD and COD of the river water. The high BOD and COD would deplete dissolved oxygen of the river water creating thereby an anaerobic condition in the riverbed, which in turn would affect the aquatic life. Gypsum, pressmud, farm yard manure, ETP sludge were tried to ameliorate the textile and dye effluent polluted soil habitat, using sunflower (CO4) as a test crop. The sludge along with effluent irrigation added considerable quantities of cations (calcium, magnesium and sodium) to the soil system. Application of pressmud @ 5 t ha-1 along with 100 per cent GR + NPK reduced the soil ESP by 44.96 per cent. The heavy metal content were also reduced due to addition of pressmud. Higher microbial population was also observed under effluent irrigation than well water. Application of 100 per cent GR + pressmud @ 5 t ha-1 + NPK under effluent irrigation increased the crop growth, yield attributes (head diameter, head weight, seed test weight) and yield of sunflower in effluent polluted soil habitat. The yield under pressmud amended plots was 36 per cent higher over control. Reclamation and restoration of textile dye effluent polluted soil habitat is possible by leaching the soil with 100 per cent GR followed by application of pressmud @ 5 t ha-1 and recommended NPK

Key words: N- Nitrogen, P- Phosphorus, K- Potassium, GR Gypsum recommendation, ESP Exchangeable sodium percentage, BOD- Biological Oxygen Demand, COD – Chemical Oxygen Demand

Abstract: In India wide stretch of coastline offers beautiful beaches for tourism, and provides a variety of edible marine molluscs that are a delight to the plate and a major source of revenue for fishermen and tourist servers. Marine molluscs have an important role in the economic and cultural life of the Tamil Nadu. Fisherman captured different types of forms by using various nets. The ornamental molluscs are emerging resources in Indian seas. The fisherman has knowledge to the collection of species, store and preservation methods. The capturing species are transported to local market and surrounding area and some aquatic forms are exported to foreign countries. Collected samples are kept for removing soft body part by three general methods are burial, boiling and sun drying. After removing the soft parts the shells are kept in acid for cleaning.Molluscan in general had a tremendous impact on Indian tradition and economy and were popular among common man as ornaments and currency. This has the increasing global demand..

Abstract: Land is the most important natural resource which embodies soil, water, associated flora and fauna involving the total ecosystem and on which all man’s activities are based. Of late, growing population pressure and human activities are increasing the demand on the limited land resources, both for agricultural and other land uses. The district Sonbhadra, previously a part of Mirzapur district in Uttar Pradesh, India, was created as a separate district in 1991. Geologically the area consists of Vindhyan supergroup, Mahakoshal group and Dudhi granitoid complex. The district Sonbhadra has rich mineral resources and their potential. The area is known for production of cement grade Limestone and Dolomite; the other minerals are Clay, Calcite, Silimanite and base metals for more than last three decades. These mining areas show impacts on the environmental status of the district. In the present study, the variations in landuse pattern from year 1971 to 2006 have been considered with the help of Survey of India toposheet and satellite data of the study area. Finally, the resulted compared landuse data of year 1971 & 2006, forest land become nearly half and open scrap get 2.5 times, agriculture land 1.5 times and huge population expansion 7.5 times, population get 3 times only in 10 year times span from 1991 to 2000.

Abstract: The extensive investigation the Sarsainawer Wetland during the study period revealed that sewage disposal, increasing human interference and resultant algal and macrophytic growth is leading to the destruction of this Wetland. Moreover Copepods dominated in oligotrophic waters whereas the Cldocerans and Rotifers are dominant in eutropilic waters which also holds good to a great extent in the present Wetland. Here also the rotifers have acquired the dominance whereas the Cladccerans tend to dominate. So, wetland is undergoing rapid eutrophication as is evident by the phytoplankton and zooplankton population recorded at different times with their seasonal drifts as well.
