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.

    Effect of pre-sowing treatments on seed germination and seedling performance of Malabar Neem (Melia dubia Cav.)
    (CCSHAU, Hisar, 2021-09) Ajay; Arya, Sandeep
    The present investigation entitled “Effect of pre-sowing treatments on seed germination and seedling performance of Malabar Neem (Melia dubia Cav.)” was conducted at Seed Science and Technology department and Nursery of forestry department, CCS Haryana Agricultural University, Hisar during 2019-20. The experiment was carried out to study the effect of pre-sowing treatment on seed germination and growth performance of Melia dubia in various growing media. Experiment was laid out in Completely Randomized Design with four replications at laboratory and three replications at nursery, respectively. Based on the research investigation, it was found that pre-sowing treatment and growing media had significantly influenced the germination and growth performance of Melia dubia. Among pre-sowing treatment on fruit showed maximum germination per cent (32.46%), viability (45.71%) and growth performance such as shoot length (15.52 cm), root length (6.78 cm), seedling dry weight (0.623 g) in cow dung for seven days which was significantly higher in all pre-treatments and on seeds maximum germination per cent (29.18%), viability (41.68%) and growth parameters was recoded in GA3 @ 100 ppm for 24 hours which was statistically at par with GA3 @ 200 ppm for 24 hours in shoot length, root length and seedling dry weight. In experiment 2, the seed treatment with different growing media, showed maximum seedling growth performance in cow dung treated fruits with sowing in cocopeat: vermiculite: vermicompost (3:1:1) that was statistically at par with cocopeat: perlite: vermiculite (3:1:1). Whereas, control (without treatment) in kernels, conc. H2SO4 for 5 minutes on fruits and sandy soil as a control in growing media showed minimum germination and growth performance.

    Improving pollination efficiency in strawberry and bitter gourd employing western honey bee, Apis mellifera L. under protective environment and field conditions
    (CCSHAU, Hisar, 2020-08) Ajay; Chaudhary, O.P.
    Present research on strawberry cv. Winter Dawn in NVPH and bitter gourd cv. Pusa Do Mausmi under IPNH was conducted at CCS Haryana agricultural University, Hisar. Five A. mellifera colony placement modes viz. i) colony permanently inside ii) colony replacement at 21 days iii) addition of larva frame at 10 days iv) addition of pupa frame at 10 days and v) colony with 2-way entrance were evaluated along with three other treatments of vi) hand pollination, vii) open pollination, and viii) control (without bee pollination). Pollination units comprised of 3-frame A. mellifera colony introduced at start of flowering. In strawberry, early flowering initiation occurred (31-35 days from transplanting) under poly house compared to open field (36 days). Flowers visitors include 17 species dominated by Hymenoptera (72.13%). A. cerana was most abundant (21.36%) followed by A. mellifera (14.05%), six non-Apis bees (25.5%) and Diptera (16.42%). Dry nectar sugar was higher in 3 DOF (5.51mg/flower) at 1100 h (3.80 mg/flower). Foraging rate (5.5-5.8/minute) and foraging speed (9.0-10.0 seconds/flower) of A. mellifera was higher under poly house treatments. Heaviest fruits were in treatments of colony added with pupa or larval frame at 10 days and colony permanently inside (26.26, 26.22 and 26.21 g/fruit). Minimum fruit yield and income was in control (14.96 tonnes/ha, Rs 14.96 lakhs/ha) and maximum in bee colony added with a pupa or larva frame at 10 days (33.82 and 33.54 T/ha) and colony permanently inside (33.32 T/ha) with marginally lower yields in colony with 2-way entrance (32.65 T/ha). Bitter gourd flowering initiated in 31-32 days with prolonged duration of 81-83 days under enclosure compared to open fields (41 and 71 days). Floral visitors comprised of 17 species and Hymenoptera was most abundant taxa (63.95%) comprising four non-Apis bees (28.37%) and four honey bees (26.00%) followed by Lepidoptera (30.56%). A. mellifera foraging rate was higher at 0800 and 1100 h (7.4 and 7.3 flowers/minute) and in all bee colony treatments (7.0-7.4/minute). Foraging speed was higher in bee treatments (4.5-4.9 seconds/flower). Staminate flowers produced maximum DNS at 0600 hours (0.318 mg/flower) and pistillate at 1000 h (0.966 mg). Maximum DNS production was in hand pollination (0.941 mg/flower) and minimum in control treatments (0.821 mg). Fruit dimensions were higher in colonies with addition of either pupa or larva frame at 10 days (151.2 x 49.7 mm each) and colony permanently inside (150.5 x 49.1 mm). Similar observations were for fruit volume, weight, TSS, acidity and other qualitative traits. In control, meagre yield (4.06 T/ha) and total income (Rs. 20,277/ha) were obtained. In treatment of bee colony added with a pupa frame recorded maximum yield and income (31.17 T/ha and Rs. 6,23,327 /ha) along with addition of larva frame (30.99 T/ha and Rs. 6,19,993/ha) followed by colony with 2-way entrance (26.44 T/ha and Rs. 5,28,883/ha). Nectar and honey stores were maximum in colony with 2-way entrance (60.4, 15.2 inches2/colony) and minimum in colonies added with pupa frame (48.0, 9.5) or larva frame at 10 days (48.0, 9.3 inches2/colony). Pollen stores were higher in treatments of colony replacement at 21 days, colony with addition of pupa frame at 10 days and colony permanently inside (30.3, 29.1 and 28.5 inches2/ colony). Maximum brood was in colony added with larva frame at 10 days (115.9 inches) followed by addition of pupa frame and colony with 2-way entrance (110.1 and 109.4 inches). Studies recommend employing treatments of colony added with either pupa or larva frame at 10 day intervals and colony with 2-way entrance for efficient pollination of strawberry and bitter gourd under enclosures.

    Evaluation of antibacterial activity of essential oils against bacterial flora of the field rodents in Hisar
    (CCSHAU, 2018) Ajay; Ravikant
    Studies on population dynamics of rodents was carried out in Seed science technology research farm area in Rabi and Kharif seasons and the field rodents were trapped during the investigation for bacterial isolation. This study was revealed that population dynamics of Rattus rattus was more as compare to, and Tetara indica in both seasons. Trap index was found highest in the second week and least in the first week of the sowing season but highest in the first week during harvesting season. Total nine bacteria were isolates from the field rodent i.e. M. musculus, T. indica and R. ratuus. On the basis of secondary biochemical tests, Salmonella, Klebsiella, Eschierichia, Citrobacter, Staphylococcus and Proteus were more prevalent in captured rodent species. To determine the antimicrobial resistance occurs in various bacterial agents isolated from rodents. The bacterial isolates were analyzed for antimicrobial susceptibility to fourteen antibiotics and four essential oils at different concentrations. The bacterial isoletes no. RRA2, TIA1 and TIA2 were found multidrug resistance towards three antibiotics (Ampicillin, Ampicillin/sulbactum, and Cefuroxime/Cephalothin) and have a great concern of matter to human and veterinary health. Thus rodents may be proving their role in spreading zoonotic diseases. The selected essential oils (i.e. Eucalyptus, lemon grass, clove and cinnamon) exhibited good antibacterial activity against all the tested bacterial isolates. Use of essential oils instead of antibiotics can help in diseases control.
