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 seed rate and row spacing on quality seed production of fenugreek (Trigonella foenum graecum L.)
    (CCSHAU, 2017) Pawan Kumar; Phor, S.K.
    The experiment entitled Effect of seed rate and row spacing on quality seed production of fenugreek (Trigonella foenum graecum L.) was conducted at Research Farm of Department of Vegetable Science, CCS Haryana Agricultural University, Hisar during winter season of 2016-17. The seed material used for the experiment was a released variety Hisar Sonali. The investigation comprising of five different seed rate (16, 18, 20, 22 and 24kg/ha) and three row spacing (20, 30 and 40cm) was laid out in a factorial randomized block design with three replications with a plot size of 2.4 x 4.0m. Ten competitive plants are selected randomly from each plot to record data on various attributes, which were affected significantly with different seed rate and row spacing. Seed rate resulted significant improvement in all the growth, seed yield and seed quality parameters. The uppermost value for number of branches per plant, days to 50% flowering, number of pods per plant, pod length, number of seeds per pod, test weight and germination percentage were recorded with seed rate of 16kg/ha. However, the plant height, biological yield, harvest index, seedling length, seedling dry weight, vigour index-I and vigour index-II were recorded utmost at seed rate of 24kg/ha. Whereas, the highest seed yield per plot and per hectare were recorded with a seed rate of 20kg/ha. Different row spacing had a significant effect on growth, seed yield and seed quality parameters. The maximum value for plant height was recorded with row spacing of 20cm. The number of branches per plant, days to 50% flowering, number of pods per plant, number of seeds per pod, pod length, seed yield per plot and per hectare, biological yield, harvest index, test weight, germination percentage, seedling length, seedling dry weight, vigour index-I and vigour index-II were recorded highest with a row spacing of 40cm. Interaction of various seed rates with different row spacing results remarkable variation for growth, seed yield and seed quality parameters. Significantly highest value were recorded for number of branches per plant, number of pods per plant, pod length, number of seeds per pod, test weight and germination percentage with treatment combination S1R3, i.e. seed rate 16kg/ha and row spacing of 40cm. The treatment combination S5R3, i.e. seed rate 24kg/ha and row spacing of 40cm, was found to be best with respect to biological yield, harvest index, seedling length, seedling dry weight, vigour index-I and vigour index-II. However, the maximum seed yield per plot and per hectare recorded with treatment combination S3R3, i.e. seed rate 20kg/ha and row spacing of 40cm.

    Studies on characterization of important viral diseases of onion and their management
    (CCSHAU, 2009) Pawan Kumar; Dhawan, Poonam
    The present investigations on symptomatology, transmission, host range, host reaction, detection and eco-friendly management of onion yellow dwarf virus (OYDV) and iris yellow spot virus (IYSV) diseases were conducted on onion crop cv. Hisar-2 during Rabi seasons 2007-08 and 2008-09 at the experimental farm, Department of Plant Pathology, CCS Haryana Agricultural University, Hisar. OYDV disease appeared in the form of crinkling and faint chlorotic stripes on the leaves of the bulb as well as seed crop. Some plants showed prominent yellow stripes on leaves and scapes of seed crop. Later on the scapes showed twisting and bending and this incidence reached at 68% in seed crop. Iris yellow spot virus showed hay coloured and water soaked spots on the leaves of bulb as well as the seed crop. The spots were found in different shapes and sizes such as diamond-shaped and irregular spots on the scapes of seed crop. These spots coalesced and led to drying. The mechanical transmission of OYDV (68.88%) and IYSV (62.5%) were successfully achieved. Nymphs of aphids such as Aphid craccivora, A. gossypii and Myzus persicae could transmit OYDV to 46.87, 53.31 and 62.5 per cent, respectively. IYSV was transmitted upto 54.17% by nymphs of Thrips tabaci. Host range of OYDV was found to be very narrow only to onion and garlic cultivars whereas, IYSV had a wide host range. OYDV and IYSV were detected by DAS-ELISA in infected onion plants. The incidence of OYDV (83.22%) and IYSV (89.97%) were recorded in bulb crop which caused losses of 14.62% and 9.85% in bulb weight due to OYDV and IYSV, respectively. A high incidence of OYDV (90.65%), IYSV (88.25%) and lodging (75.68%) was recorded in seed crop. The reduction in seed yield (53.84%) was observed maximum in plants infected with OYDV grade A and least (6.6%) in OYDV grade D. A reduction of 50% in seed yield was recorded with IYSV disease with a substantial reduction in seed quality. None of the management strategies tried was effective for reducing OYDV incidence whereas incidence of IYSV (67.24%) and lodging (40.27%) was reduced in late planted crop i.e. 12th Nov., 2009. But at the same time seed yield was also reduced 34.22% due to late planting. None of the varieties/collections was found resistant to onion yellow dwarf virus and iris yellow spot virus diseases. All the varieties/collections were found highly susceptible to both diseases. There is a need to screen more germplasm lines to find sources of resistance to these viral diseases.

    Studies on the effect of drying methods and packing material on the shelf life of aonla powder (Emblica officinalis G.)
    (CCSHAU, 2011) Pawan Kumar; Surinder Kumar
    The present investigation was carried out in the Fruit Processing Laboratory of Department of Horticulture, CCS, Haryana Agricultural University, Hisar. Powder of aonla fruits was prepared by blanching of aonla fruits in boiling water (98±2˚C) with five different concentration of KMS viz. 0ppm, 250ppm, 500ppm, 750ppm and 1000ppm KMS. After blanching the seeds were removed from the fruits and fruit pulp was dried in oven tray drier at (60˚C) and in solar tunnel drier. After dehydration, product was grinded into powder and packed in aluminium laminated bags and in polythene bags. Packed samples of powder were stored at ambient temperature with objective to study the effect of drying methods and packing material on quality of aonla powder during storage. During studies of drying of aonla pulp it was observed that the rate of moisture loss was fast in oven tray drier as compared to solar tunnel drier at each interval of time period. Moisture content of dehydrated product was recorded (9.04%) in solar tunnel dried and (8.21%) moisture content in oven tray dried fruit pulp. Maximum recovery percentage (10.37%) of aonla powder was recorded from fruits treated with 1000ppm KMS as compared to minimum (10.12%) recovery percentage from fruits treated with 0ppm KMS irrespective of drying methods. Loss of ascorbic acid content and acidity content was observed during blanching and drying. Maximum retention of ascorbic acid content (514.00 mg/100g) was recorded from fruits blanched with 1000ppm KMS. Maximum reduction in acidity content was recorded from 2.11% to 1.46% in fruits blanched with 0ppm KMS. During storage of aonla powder ascorbic acid, acidity, total sugars and reducing sugars content were decreased with increase in storage period whereas non-enzymatic browning and non reducing sugars increased with increase in storage period. During present investigation, it was also observed that fruits treated with 1000ppm KMS had retained maximum ascorbic acid and acidity content and recorded minimum non-enzymatic browning in both drying methods during storage, whereas fruits treated with 0ppm KMS had retained minimum ascorbic acid and acidity content and had maximum browning during storage. Sugars content were at par with each other with increase in concentration of KMS in both the drying methods. Maximum total sugars, reducing sugars and nonreducing sugars content were recorded in oven tray dried aonla powder during storage.

    (CCSHAU, 2012) Pawan Kumar; Bhatia, A.K.
    The experiment entitled“Effect of seed size, spacing and nitrogen on seedpotato production cv. Kufri Bahar.” was conducted at Research Farm of the Department of Vegetable Science, CCS Haryana Agricultural University, Hisar during winter season of 2009-10. The experiment comprising of three seed size (25-50 g, >50-75 g and >75-100 g), three plant spacing (60x10, 60x15 and 60x20 cm) and two nitrogen level (100 and 125 N kg/ha) was laid out in a randomized block design with three replications keeping net plot size 3.6x3.0 m. Ten competitive plants were selected randomly from each experimental treatment to record data on various parameters, which were influenced significantly by different seed size, plant spacing and nitrogen levels. The per cent plant emergence, plant height, leaves/stem, leaf area index, number of tubers up to 25 g, >25-50 g and >50-75 g grade, total numberof tuber, weight of tuber >25-50 g and >50-75 g grade were statistically higher with seed size >75-100 g tubers. However, the value for number of stems per hill, leaves weight per hill, stem weightand weight of foliage, number of tubers per plot >75 g grade, weight of tubers up to 25 and >75 g and total tuber yield was maximum with >50-75 g seed size tubers. Different plant spacing exhibited significant difference for growth and yield parameters. The maximum value for plant height, stem/hill, leaves/stem, leaf area index , leaves weight, stem weight, weight of foliage, number of tubers >50-75 g and >75 g grade, total number of tubers, weight of tubers up to 25 g, >25-50 g >50-75 g, >75 g grade and total tuber yield were maximum with 60x20 cm plant spacing. However, per cent plant emergencewas found maximum with plant spacing 60x15 cm and number of tubers up to 25 g and >25-50 g grade tubers per plot were found maximum with plant closest spacing of 60x10 cm. Effect of nitrogen level showed remarkable variation for growth and yield parameters except per cent plant emergence. Significantly highest value was registered for plant height, stem/hill, leaves/stem, leaf area index, leaves weight, stem weight, weight of foliage, numberof tubers up to 25 g, >25-50 g, >50-75 g and >75 g, total number of tubers, weight of tubers up to 25 g, >25-50 g >50-75 g and >75 g grade, total tuber yield with nitrogen 125 kg/ha. However, plant emergence found maximum with nitrogen 100 kg /ha. Kufri Bahar produced highest total tuber yield 437.14 q/ha when >50-75 g seed size tubers were planted at a spacing 60x20 cm and nitrogen level 125 kg/ha which was followed by seed size >75-100 g, plant spacing 60x15 cm and nitrogen level 100 kg/ha.
