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.

    Performance of organically cultivated papaya under different irrigation levels and mulching methods
    (CCSHAU Hisar, 2022-09) Baljeet Singh; Mukesh Kumar
    An experiment was conducted at research field of Deendayal Upadhyay Centre of Excellence for Organic Farming, CCS HAU, Hisar during the year 2021-22 to study the effect of different irrigation levels and mulching methods on performance of organically cultivated papaya. The experiment comprised of twenty one treatments under the drip irrigation method with combination of three different irrigation levels viz. 50%, 75% and 100% of crop water requirement and seven mulching methods. The results showed that the plant height (240.73 cm), stem girth (46.03 cm), crown diameter (245.40 cm), number of flowers (65.67), number of fruits (42.67), yield per plant (54.30 kg) and total yield (135.75 t ha-1) were observed maximum for meeting 100% of crop water requirement with the application of 10 cm thick straw mulch in two-meter diameter around the plant and minimum for meeting 50% of crop water requirement without mulch condition. The soil moisture (20.18%) was found maximum for meeting 100% of crop water requirement with the application of plastic mulch in twometer diameter around the plant and minimum for meeting 50 % of crop water requirement without mulch condition. From the results, it is also observed that the irrigation water use efficiency (59.53 kg m-3) was found maximum for meeting 50 % of crop water requirement with 10 cm thick straw mulch in two-meter diameter around the plant and minimum (42.64 kg m-3) for meeting (42.64 kg m-3) 100% of crop water requirement without mulch under drip irrigation system.

    Response of onion with different irrigation frequency and lateral spacing under subsurface drip system
    (CCSHAU, Hisar, 2021-08) Deokar Gopal Kathalu; Sanjay Kumar
    An experiment was conducted to study soil water dynamics and yield response of onion crop with irrigation frequencies (one, two, three and four days) and lateral spacing (45cm and 60cm) under subsurface drip irrigation during the spring summer season 2020 and 2021 in 2m x 2m micro plots, built in the field area of Department of Soil and Water Engineering, CCSHAU, Hisar, Haryana, India. At the middle of 45cm and 60cm lateral spacing with daily irrigation, available moisture in the root zone (0-60cm) was 12.73cm and 12.33cm respectively, which was higher by 3.14% in 45cm lateral spacing than 60cm. Average highest (102.28 g) fresh weight of onion bulb and number of bulbs per m2 for grade A, B and C of onion of two seasons was recorded in I2L45 treatment. Highest bulb yield of onion under grade A (>5.0cm), B (4.0-5.0cm) and C (4.0-5.0cm) was recorded in I2L45 treatment, whereas its lowest value under the respective grades was obtained in I4L60 treatment. Under two days irrigation interval with 45cm lateral spacing (I2L45), the total bulb yield was obtained 9.98% higher than 60cm lateral spacing (I2L60) treatment during year 2020, whereas, it was 9.22% higher in year 2021. The highest (11.55 kg m-3 in 2020 and 10.09 kg m-3 in 2021) and lowest (9.99 kg m-3 in 2020 and 9 kg m-3 in 2021) irrigation water use efficiency was observed in I2L45 and I4L60 treatments, respectively. On the basis of soil water dynamics, superior quality and highest yield of onion in sandy loam soil, it is concluded that subsurface drip irrigation with two days irrigation interval with 45cm lateral spacing gives better performance as compared to one, three and four days irrigation in 45 as well as 60cm lateral spacing.

    Effect of wind speed and spacing on distribution uniformity of sprinkler irrigation system
    (CCSHAU, Hisar, 2020-12) Raj Kumar; Ram Naresh
    An experiment was conducted to study the effect of wind speed (0-4 km/h, 4-8 km/h and 8-12 km/h), direction (North-West and North-East) and spacing (6 m × 6 m, 6 m × 9 m and 9 m × 12 m) on uniformity distribution of sprinkler irrigation system at the field of the village Luhana located in Western Haryana., India. For spacing 6 m × 6 m and wind speed range 0-4 km/h, the maximum distribution uniformity was 86.33%. Similarly at ranges of wind speed 4-8 km/h and 9-12 km/h, the average distribution uniformity was 82.88% and 81.42% respectively. For spacing 6 m × 9 m was used, the average distribution uniformity was 75.42% at a range of wind speed 0-4 km/h. Similarly at ranges of wind speed 4- 8 km/h and 8-12 km/h, the average distribution uniformity was 75% and 74.16% respectively. For spacing 9 m × 12 m was used, the average distribution uniformity was 68.20% at a range of wind speed 0-4 km/h. Similarly at ranges of wind speed 4-8 km/h and 8-12 km/h, the average distribution uniformity were 66.17% and 66.60% respectively. It shows that the combination of spacing 6 m × 6 m and wind speed 0-4 km/h gives a higher distribution uniformity. From this it is evident that for maintaining distribution uniformity more than 75%, for wind speed 0-4 km/h sprinkler spacing should not be more than 6 m x 9 m and for wind speed 4-8 km/h sprinkler spacing should not be more than 6 m x 6 m while for wind speed range 8-12 km/h should be less than 6 m x 6 m.
