Chaudhary Charan Singh Haryana Agricultural University, Hisar

Chaudhary Charan Singh Haryana Agricultural University popularly known as HAU, is one of Asia's biggest agricultural universities, located at Hisar in the Indian state of Haryana. It is named after India's seventh Prime Minister, Chaudhary Charan Singh. It is a leader in agricultural research in India and contributed significantly to Green Revolution and White Revolution in India in the 1960s and 70s. It has a very large campus and has several research centres throughout the state. It won the Indian Council of Agricultural Research's Award for the Best Institute in 1997. HAU was initially a campus of Punjab Agricultural University, Ludhiana. After the formation of Haryana in 1966, it became an autonomous institution on February 2, 1970 through a Presidential Ordinance, later ratified as Haryana and Punjab Agricultural Universities Act, 1970, passed by the Lok Sabha on March 29, 1970. A. L. Fletcher, the first Vice-Chancellor of the university, was instrumental in its initial growth.

    Physiological studies in wheat genotypes (Triticum aestivum L.) under terminal high temperature conditions
    (CCSHAU, 2017) Pooja; Munjal, Renu
    The present investigation was conducted to evaluate various physiological traits & identify promising wheat genotypes under terminal high temperature condition. The twenty genotypes i.e. ten tolerant (WH 730, WH 1124, WH 1021, HD 3059, DBW 90, PBW 373, Raj 3765, HD 2851, HD 2285, PBW 550) & ten heat susceptible (HD 2967, DPW 621, WH 1105, DBW 88, HD 3086, HD 2733, WH 711, WH 1080, WH 1142 & K 0307) were grown during rabi season of 2016 - 17 at Field Crop Research Area, of Wheat & Barley Section, Department of Genetics & Plant Breeding, CCS HAU, Hisar, The experiment was laid out in factorial RBD consisting of 4 rows of 3m length with a 20×5 cm spacing within rows & between plants, respectively. Terminal high temperature significantly influenced physiological, biochemical, yield & yield attributes in both heat susceptible & heat tolerant genotypes but the reduction was more pronounced in the susceptible genotypes in comparison to the tolerant ones. WH 1021 was adjudged to be most tolerant genotype due to minimum reduction in photosynthetic rate, transpiration rate, chlorophyll content & minimum increase in canopy temperature, cell membrane stability. WH 1021 also showed maximum no. of productive tiller/ m row length, biomass, grain yield, thousand grain weight & maximum harvest index. K 0307 was adjudged to be most susceptible due to maximum reduction in all physiological & biochemical trait except chlorophyll fluorescence & canopy temperature. K 0307 showed poor performance in yield & yield attributes. The tolerant genotype WH 1021 was found to be the most suitable one under terminal high temperature conditions on the basis of the overall picture of physiological, morpho-physiological & yield traits studied.

    Studies on salicylic acid induced amelioration of salinity stress in mungbean [Vigna radiata (L.) Wilczek]
    (CCSHAU, 2007) Pooja; Sharma, K.D.
    The study entitled, “Studies on salicylic acid induced amelioration of salinity stress in mungbean [Vigna radiata (L.) Wilczek]” was conducted during kharif season of 2006 at screen house, Department of Botany and Plant Physiology, CCS Haryana Agricultural University, Hisar. The experiment was laid out in factorial CRD with three replications. The treatment consisted of two levels of salinity stress (4 and 6 dSm-1) maintained after germination and two concentration of salicylic acid (0.25 and 0.50 mM) applied as foliar spray at flower initiation. The observations were recorded 2 and 6 days after salicylic acid (SA) spray. Salinity stress decreased the growth of mungbean in terms of plant height, dry matter accumulation and leaf area. However, treatment with SA increased the growth parameters under salinity stress. All the plant water status parameters i.e. w, s and RWC decreased with increasing level of salinity stress. Application of SA improved the plant water status irrespective of salinity levels. Gaseous exchange studies i.e. rate of photosynthesis, transpiration and stomatal conductance get reduced under salinity stress. Higher concentration of SA was more effective to brought consecutive improvement in gaseous exchange under salinity. Membrane injury and lipid peroxidation enhanced under salinity stress but salicylic acid application increased the membrane stability and decreased MDA production. Biochemical metabolites i.e. chlorophyll and protein content declined under salinity stress. However, free proline, total soluble carbohydrates and free amino acids content showed sharp rise under salinity stress. Exogenous SA application increased all the above biochemical metabolites under salinity. The ionic composition i.e. Na+, Cl- and SO4- increased but decline in K+ content in leaves under salinity stress. Salicylic acid reversed the accumulation trend under stressed condition. Seed and biological yield reduced significantly by decreasing yield attributing characters i.e. number of effective pods, seeds per plant and test weight under salinity stress. Salicylic acid improved the yield and its attributes by maintaining plants water status and various physiological and biochemical processes.
