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.

    Studies on the ecofriendly management of Powdery mildew (erysiphe cruciferarum opiz ex. Junell) of mustard (brassica juncea (linn.) Czern & Coss)
    (CCSHAU, 2004) Karn Singh; Mehta, Naresh
    Powdery mildew caused by Erysiphe cruciferarum Opiz ex. Junell is one of the important disease of mustard (B. juncea (L.) Czern & Coss) growing all over the India. Disease progression was maximum during mid of March (15-3-04) on all the four varieties in all the three staggering dates of sowing when T. Max. 32.5ºC, T. Min. 12.7ºC, RHM 94.5 per cent, RHE 38.5 per cent, Avp. M 12.30mm, Avp. E 14.30 mm, Wind Speed 2km/hr and Sunshine 8.80 hrs. Disease intensity and AUDPC increased from 48-74 per cent and 326-440 respectively with delay in date of sowing. The apparent infection rate also observed higher during mid of March on all the varieties during first two dates of sowing. In third date of sowing apparent infection rate was maximum after mid of March i.e. 3 days later. Amongst nine varieties evaluated for slow mildewing components, the speck size, no. of specks/leaf, no. of conidia/speck, disease progression and disease intensity were less in the slow mildewing variety GSL-1 as compared to fast mildewing cultivars/varieties such as RH-30, RH-9801, RH-9304 RH-8812, RH-9901, RC-781 and Purple Mutant. The disease did not appear in the variety HC-9603. Maximum yield loss was recorded in the variety RH-9304 (29.47%) followed by RH-9801(26.04%), RH-8113 (23.03%) and RH-30 (19.0%) whereas average yield loss was 24.55 per cent. Among the fifty four varieties/lines tested for resistance against powdery mildew under field conditions, eleven varieties/lines viz. YSPb-24, TH-68, GSL-1, Midas, MNS-9605, HC- 1, HC-2, HC-9605, HC-9603, B. alba and Sinapis alba were observed as resistant, five varieties/line viz. Domo-4, BSH-1, TMH-50, TMH-52 and T-27 as moderately resistant to powdery mildew. Similarly, six varieties/lines such as Vaibhav, Varuna, Kranti, RLM-1359, RL- 198 and B. chinensis were susceptible and all other varieties/lines were moderately susceptible to powdery mildew. Powdery mildew can be effectively controlled by foliar application of Karathane (0.1%), Sulfex (0.2%), Salicylic acid (0.05%) and Nimbicidin (0.15%). Sulfex (0.2%) was most economical in managing the powdery mildew and gave maximum B:C ratio 6.34:1, 8.24:1 in both the varieties RH-9801, RH-9304 respectively. It was followed by Salicyclic acid 2.53:1, 3.24:1 in both the varieties RH-9801 and RH-9304 respectively.

    Effect of Cd toxicity and its possible alleviation by putrescine/spermidine and ascorbic acid in Pisum sativum L.
    (CCSHAU, 2004) Anita Kumari; Sheokand, Sunita
    The present investigations were conducted on pea genotype hisar harit to study the accumulation of cd in different plant parts and to evaluate the causes of cd toxicity in relation to antioxidant defence mechanism and its possible amelioration by ascorbic acid and putrescine. in the first experiment plants were grown in dune sand treated with 0, 100, 200 and 400 m cdcl2. Cd caused significant but variable decline in dry weight of all the plant parts, though it accumulated mainly in the roots. in the second experiment the effect of cd on reactive oxygen species (ros) scavenging enzymes was studied. The plants were treated woth 0, 100, 400 and 800 m cdcl2 at the vegetative stage and sampled after 3 and 9 day. Cd induced a significant increase in lipid peroxidation in the leaves and nodules, but had no appreciable effect on total soluble protein and non-protein thiols. A concentration dependent increase in ros production was observed, which could be compensated to some extent by increased activity of sod, apx and cat isoforms in leaves. higher concentrations of cd resulted in a decrease in sod and apx activity could be compensated to some extent by increased catalase activity in the nodules. in the third experiment the effect of ascorbic acid and putrescine on cd induced toxicity in leaves and nodules was studied. Ascorbic acid was more effective in ameliorating the deleterious effects of cd on plant growth, lipid peroxidation and ros production. Among the antioxidant enzymes, asa had a positive effect on apx isozymes in cd treated plants. Among the two putrescine concentration used, the lower concentration of 0.5 mm. Was more effective in ameliorating the toxic effects of cd. Putrescine had a positive effect on catalase and sod isozymes. Key words: Pisum sativum L. , cadmium, antioxidative enzymes, reactive oxygen species(ROS).
