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.

    Salt and water dynamics in soil under drip irrigation system on cole crop
    (CCSHAU, 2012) Sharma, Parmod; Sanjay Kumar
    leaching of excessive salts, selection of salt tolerant crops, frequent application of water etc. Thus, a field experiment was conducted at CCS Haryana Agricultural University, Hisar to study the salt and water dynamics in soil under drip irrigation system on cabbage crop and to investigate the effect of frequency and salinity levels of irrigation water on cabbage. The residual moisture content in the root zone after 90 days of transplanting showed increasing trend with increasing level of salinity of irrigation water beyond ECiw 3 dS/m. Equal amount of water application coupled with information on residual moisture content in the rootzone suggested that cabbage plants utilized lesser amount of water with increasing level of salinity beyond ECiw 3.0 dS/m. In daily irrigation under saline water of ECiw 12 dS/m (F1S5), the ECe values after 90 days of transplantation increased by 206.4, 222.1, 244.4 and 264.1% on comparing with initial values in 0- 15, 15-30, 30-45 and 45-60 cm layers, respectively. In alternate day irrigation under saline water of 12 dS/m (F2S5), the ECe values after 90 days of transplantation increased by 279.2, 262.7, 270.1 and 280.2% on comparing with initial values in 0-15, 15-30, 30-45 and 45-60 cm layers, respectively. In daily irrigation, harvesting was started early (60 days after transplanting) in canal water, saline water of ECiw 3 and 6 dS/m, whereas, in alternate day irrigation, it was in canal water and saline water of ECiw 3 dS/m. The date of first harvesting was also affected by the quality of irrigation water. Use of highly saline water (ECiw > 6 dS/m) resulted into delay of first harvesting by about 20 days as compared to the use of relatively good quality water suggesting that use of good quality and saline water in different parts of the fields may be effectively used to prolong the productive season of cabbage. In daily irrigation treatment, the relative yields obtained were 100.53, 90.75, 67.82, and 41.68 % in F1S2, F1S3, F1S4 and F1S5 treatments, respectively, as compared to the yield recorded in canal irrigation (F1S1). In alternate day irrigation treatment, the relative yields obtained were 100.8, 86.16, 60.30 and 28.63 % in F2S2, F2S3, F2S4 and F2S5 treatments, respectively, as compared to the yield recorded in canal irrigation (F2S1). Higher yield of cabbage under daily irrigation as compared to alternate day irrigation for different levels of salinity of irrigation water suggested the importance of high frequency of irrigation for the use of saline water.

    Performance evaluation of traveler irrigation system
    (CCSHAU, 2012) Jangra, Pardeep; Jhorar, R.K.
    Efficient irrigation can only be attained through controlled and uniform application of water and therefore, a lot of emphasis is being given for the adoption of pressurised irrigation systems. One of the latest pressurised irrigation systems, traveler irrigation system is being introduced in Indian farming conditions. Therefore, a study about traveler irrigation system was conducted at the RDS seed farm, CCSHAU, Hisar. The major objectives of the study were to evaluate the hydraulic performance of traveler irrigation system along the travel path and to identify the operational aspects of traveler irrigation system. The traveler irrigation system was operated at three speeds i.e. speed 1 (25.42 m h-1), speed 2 (52.00 m h-1) and speed 3 (82.94 m h-1). The average depth of water application was measured as 11.45, 8.12 and 5.95 mm for speed 1, speed 2 and speed 3, respectively. The average width of the wetted strip was 49.5 m for speed 1 and 2, and 50.0 m for speed 3. The water distribution/precipitation profile of the traveling gun was found to be of trapezium/trapezoidal shape. The coefficient of uniformity as well as depth of water application was lower in the start end area of the travel path as compared to the middle area. Maximum value of the coefficient of uniformity as well as distribution uniformity for different speeds was attained when 20 to 30 per cent overlap was assumed between the adjacent travel paths. To attain maximum uniformity of water application the tested traveler irrigation system should be operated at adjacent travel path distance of 35 to 40 m, when wind velocity is within 9.0 km h-1 and pressure at the gun is about 3.0 kg cm-2.
