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.

    Indole acetic acid production by Pseudomonas species and its effect on plant growth of green gram and black gram
    (CCSHAU, 2004) Om Prakash; Sindhu, S.S.
    In the present studies, IAA producing Pseudomonas strains CPS59 and MPS90 were mutagenized with transposon Tn5 using E. coli strain S17-1. The frequency of mutants with low amount of IAA production varied from 35.14 to 46.75% from Pseudomonas strains CPS59 and MPS90, respectively and only 3.43 to 3.75% mutants produced higher levels of IAA in comparison to respective parent strains in LB medium supplemented with tryptophan. Inoculation of mutants derived from Pseudomonas strain CPS59 showed stunting effect on root development of green gram seedlings at both 5 and 10 days of observation whereas mutants CPS59-138, CPS59-162 and CPS59-231 showed stimulatory effect on root growth at 5 days in black gram. Majority of the mutants caused stimulation of shoot growth at both 5 and 10 days of observation in comparison to uninoculated treatment. MPS90-derived mutants i.e. MPS90-39, MPS90-157, MPS90-102 and MPS90-106 showed slight stimulation of root growth whereas most of the mutants showed stunting effect on shoot growth at 10 days in black gram. Coinoculation studies of Pseudomonas mutants with Bradyrhizobium sp. strain S24 resulted in increased nodule number, nodule fresh weight and shoot dry weight in green gram and black gram under chillum jar conditions. Shoot dry weight gains in green gram after coinoculation with CPS59-derived mutants varied from 107-149 per cent and from 110-137 per cent with MPS90-derived mutants in comparison to Bradyrhizobium-inoculated plants at 60 days of growth. Similarly, shoot dry weight gains in black gram varied from 102-178 per cent and 105-198 after inoculation with mutants derived from CPS59 and MPS90, respectively. The stimulation effect on shoot dry weight in comparison to uninoculated control treatment varied from 280-390 per cent in green gram and 179-357 per cent in black gram. Four mutants CPS59- 138, CPS59-321, MPS90-133 and MPS90-51 showed more enhancements in nodule formation by Bradyrhizobium strain S24 in green gram whereas mutants CPS59-162, CPS59-64, MPS90- 102 and MPS90-280 caused more stimulation for nodule formation in black gram at 60 days of plant growth. Significant enhancements in shoot dry weights of green gram were observed by coinoculation with Pseudomonas mutants CPS59-138, CPS59-231, CPS59-321, MPS90-280, MPS90-14 and MPS90-145. Similarly, coinoculation of Bradyrhizobium strain with Pseudomonas mutants CPS59-162, CPS59-321, CPS59-214, MPS90-102, MPS90-280 and MPS90-51 showed significant gains in shoot biomass of black gram at 60 days of plant growth. The better performance of IAA over producing mutants in relation to nodulation and plant biomass indicated that IAA production by Pseudomonas strains is a beneficial trait for selection of rhizobacterial strains having plant growth promotion ability.

    Epidemiology and management of anthracnose of chilli (Capsicum annuum) caused by Colletotrichum capsici (Syd.) Butler and Bisby
    (CCSHAU, 2011) Om Prakash; Khirbat, S.K.
    Studies on epidemiology and disease management through fungicides, bacterial antagonist as well as plant extract under field conditions were carried out with Colletotrichum capsici causing anthracnose of chilli. Pre and post inoculation moist period studies revealed that minimum post inoculation moist period for initiation of the disease was 12 hours with maximum infection at 72 hours. However, pre inoculation moist period resulted in increased infection but was not as effective as post inoculation moist period for disease development under screen house conditions. In host range studies, the pathogen was found to infect three Kharif crops (cotton, raddish and black gram) and four weeds (sawank, kagaroti, kharjal and mirch booti). Pseudomonas fluorescens (Ludhiana isolate) was effective in reducing the growth of pathogen in vitro conditions. In some plant extract studies, the marigold 50% was effective for reducing the growth of pathogen and gave 100 per cent spore germination inhibition in vitro conditions. In studies with fungicides, mancozeb and carbendazim at 0.2% concentration were much effective in reducing the die back incidence. In field studies against fruit rot of chili with fungicides, antagonist and plant extract revealed that mancozeb and carbendazim at 0.2% concentration were equally and significantly effective in reducing the fruit rot severity. However, Pseudomonas fluorescens (Ludhiana isolate) and marigold plant extract (50%) were not much effective in reducing the fruit rot severity. Out of ten chilli germplasm lines, NCH-1124 and LCA-301 were found to be moderately resistant to the disease. Biochemical studies indicated that the resistant varieties contain higher ascorbic acid content and less total sugar. While comparing the different stages of fruits, the red fruits of resistant varieties were having much higher ascorbic acid content and less total sugars as compared to green and turning red stages of chilli fruits.
