    (CCSHAU, Hisar, 2021-09) Mehta, Pragya; Gajender Singh
    The study was carried out in Ottu reservoir which is situated in Sirsa city of Haryana, India. Evaluation and quantification of fish food organisms and aquatic weeds of Ottu reservoir were monitored from March 2021 to June 2021. The evaluation of the planktonic population revealed that there were 36 genera of plankton recorded. Out of this 19 genera of phytoplankton belongs to class Bacillariophyceae (3 genera), Cyanophyceae (3 genera), Chlorophyceae (11 genera), Euglenophyceae (2 genera) and 17 genera of zooplankton belongs to class Copepoda (9 genera), Rotifera (2 genera), Cladocera (4 genera), and Protozoa (2 genera). In various months maximum, 123 species of phytoplankton were observed in site 2 and site 4 and Chlorophyceae found as dominant group while in zooplankton in various month site 4 showed maximum 391species of zooplankton and Cladocera group found as the dominant group. The highest quantity of plankton was observed in April while the minimum quantity was observed in March. Shannon and Weaver's diversity index for plankton found maximum in site 1(3.35) and minimum in site 4 (3.25). In site 1 and site 2 significant difference (P<0.05) was observed for the phytoplanktons groups present every month from March to June. However, a non-significant difference was observed in site 3 and site 4.Whilst the zooplankton group present in site 1, site 2, site 3, and site 4 from March to June was also found significant. A total of 7 species of aquatic weeds recorded 4species (Eicchornia crassipes, Lamnea minor, Pistia stratiotes and Nympahea alba) belongs to free floating aquatic weeds, 2 species (Ceratophyllum demersum , Hydrilla verticelleta) belongs to submerged aquatic weeds and 1 species (Typha latifolia) belongs to Emergent aquatic weeds. A total of 17 benthic species of benthos identified belongs to 2 phylum viz. annelida (3 species) and mollusca (14 species) and in mollusca 2 class viz. gastropoda and bivalve recorded. Maximum benthic fauna recorded in June.

    (CCSHAU, 2019) Goyal, Alisha; Anita Kumari
    The present investigation was aimed to evaluate physiological traits for carbohydrates accumulation and mobilization and to find correlation between physiological traits and high temperature tolerance. Ten wheat genotypes viz DBW14 (Check), PBW781, PBW821, RAJ3765 (Check), RWP-2018-26, RWP-2018-30, RWP-2018-31, RWP-2018-32, WH1239 and WH730 (Check) were sown under TS and LS conditions during rabi season of 2018 - 19 at wheat research farm, Department of Genetics & Plant Breeding, CCS HAU, Hisar. The experiment was laid out in factorial RBD consisting of 6 rows of 3m length with a 20×5 cm spacing within rows & between plants, respectively. Data were recorded for various morphological traits including number of days to heading, number of days to maturity, plant height (cm), number of productive tillers per plant, spike length (cm), number of spikelets per spike, grain yield per plant (g), biological yield per plant (g), grain weight, number of grains per spike, 1000-grain weight (g), heat susceptibility index. Other studied parameters include normalized difference vegetation index, canopy temperature, transpiration rate, photosynthetic rate, stomatal conductance, chlorophyll content, cell membrane stability, free radical scavenging activity, osmotic potential, water soluble carbohydrates from different parts of stem, stem solidness, stem dry weight and grain growth rate. Out of ten genotypes, PBW821 was identified as thermo-tolerant on the basis of maximum NDVI & minimum CT at 90DAS, photosynthetic rate, transpiration rate, stomatal conductance, cell membrane stability, osmotic potential, water soluble carbohydrate, stem solidness and stem dry weight. PBW821 also showed maximum no. of spikelet/spike, no. of grains/spike, grain weight, biomass and grain yield under LS condition. Water soluble carbohydrate were found highly correlated with stem dry weight at maturity, stem solidness at 90DAS, stem dry weight at 90 DAS and biomass and stem solidness was also found highly correlated with biomass, stem dry weight at 90 DAS, grain growth rate and stem dry weight at maturity.

    Effect of planting season on seed yield, yield components and seed quality in maize hybrids (Zea mays L)
    (CCSHAU, 2018) Nidhi; Bhuker, Axay
    Four maize hybrids produced during rabi and kharif seasons were evaluated for their performance for different viability, vigour and yield parameters viz. standard germination, seedling length, seed weight, seed density, seedling dry weight, vigour index-I, vigour index-II, accelerated ageing test, electrical conductivity, tetrazolium test, dehydrogenase activity test, catalase activity test, peroxidase test, lipid peroxidation test, protein content, field emergence index, seedling establishment, number of leaves, number of cobs, cob length, plant height, days to 50 % tasseling, days to 50% silking, number of seeds per cob and seed yield to assess the effect of planting season on seed yield, yield components and seed quality in maize hybrids. The rabi season produced seed showed superiority over kharif season for all the seed quality and yield parameters. Among the hybrids, HQPM-5 had the top rank for almost all the vigour, viability and yield parameters in both the seasons (rabi and kharif) indicating its superiority over other hybrids. Standard germination was found significantly and positively correlated with most of the seed quality parameters except electrical conductivity and lipid peroxidation in both the seasons. Electrical conductivity and lipid peroxidation was found significantly and negatively associated with most of the parameters recorded in laboratory and field. On the basis of correlation study, it can be concluded that the viability test like tetrazolium test, electrical conductivity test, dehydrogenase activity test, accelerated ageing test, catalase activity test and lipid peroxidation test can be used as reliable predictor of standard germination in maize and rabi season can be considered as a better option for the production of quality seed in maize in Haryana

    Assessment of ground water quality of Kaithal and Guhla blocks of Kaithal district, Haryana
    (CCSHAU, 2016) Vijay Kant Singh; Ram Prakash
    Kaithal, the north eastern district of Haryana State with a total geographical area of 2317 sq. km is located between 29 o 31’: 30 o 12’ North latitudes and 76 o 10’: 76 o 42’ East longitudes. To ascertain the quality of groundwater and its impact on chemical properties of soil, water samples were collected from all the villages of Kaithal and Guhla blocks and analyzed by standard methods. 241 water samples were collected and analyzed for pH, electrical conductivity (EC), soluble cations (Ca 2+ , Mg 2+ , Na + and K + ) and anions (CO 3 2− , HCO 3 − , Cl − , SO 4 2− and NO3 − ) by using standard procedures. The values of SAR and RSC of water samples were computed. The pH, EC, SAR and RSC in groundwater ranged from 7.36-9.80, 0.30-2.31 (dSm -1 ), 2.55-14.39 (mmol l -1 ) 1/2 and nil-5.80 (me l -1 ), respectively in Guhla block and from 7.25-9.25, 0.47-6.06 (dSm -1 ), 3.69-28.59 (mmol l -1 ) 1/2 , nil-5.70 (me l -1 ) in Kaithal block. According to AICRP classification, 63.2, 2.7, 11.1, 22.1 and 0.9% samples were found to be of good, marginally saline, marginally alkali, alkali and highly alkali, respectively in Guhla block and 31.1, 26.5, 8.3, 8.3, 9.9 and 15.9% were of good, marginally saline, high SAR saline, marginally alkali, alkali and highly alkali, respectively in Kaithal block. After categorization of water samples, 84 soil samples from 21 representative profiles were collected from depth, 0-15, 15-30, 30-45 and 45-60 cm which were analyzed for pH, EC e , CEC, ESP, available N, P, K, OC, CaCO 3, soluble cations (Ca 2+ , Mg 2+ , Na + , K + ) and anions (CO 3 2− , HCO 3 -, Cl − , SO 4 2− ,) by standard procedures. In Guhla block, lowest pH of saturation extract was found in village Sultania and highest in Kasauli, while in case of Kaithal block lowest in Titram village and highest in Mundri. In Guhla block, lowest EC e (1.20 dSm -1 ), SAR e 2.87 (mmol l -1 ) 1/2 and ESP (3.83) were found in Kharkhada village while highest ECe (4.63 dSm -1 ) in Bhagal, SAR e 16.65 (mmol l -1 ) 1/2 and ESP (20.31) in Dusharpur. In case of Kaithal block, lowest EC e (1.70 dSm -1 ) in Jagdishpura, SAR e 3.28 (mmol l -1 ) 1/2 and ESP (4.23) were in Titram while highest EC e 6.67 (dSm -1 ) in Khurana, SAR e 20.33 (mmol l -1 ) 1/2 and ESP (25.55) in Ujana village. In Guhla block, lowest CEC 6.66-10.07 (cmol(+)kg -1 ) observed in Kasauli village and highest 13.82-15.26 (cmol(+)kg -1 ) in Bhagal village. In Kaithal block, lowest 5.37-8.73 (cmol(+)kg -1 ) in Mundri and highest 11.57-14.24 (cmol(+)kg -1 ) in Chandana village. Soil profiles were collected based on different categories of irrigation water. Most of the profiles were having salt developed due to the presence of salts in irrigation water. Most of the soil profiles were low in fertility. Highest electrical conductivity and sodium adsorption ratio of saturation extract were observed in surface layers of the soil which gradually decreased with depth irrespective of quality of irrigation water. After the analysis of soil and water, the Arc Map 9.3 was used to create various thematic maps like pH, EC, SAR and RSC of the study area. These thematic maps were combined to prepare water quality maps.
