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.

ThesisItem Open Access Hydraulic performance evaluation of drip irrigation system with different emission devices(2005) Sandeep Kumar; Partap SinghStudies were conducted to evaluate the effect of operating pressure head and spacing on different hydraulic performance evaluation measures of drip irrigation systems with different emission devices. The commonly used hydraulic performance evaluation measures considered were uniformity coefficient, emission uniformity, coefficient of variation and coefficient of manufacturing variation. The different emission devices were dripper, micro-tube, drip-in and drip tape. The experiments were conducted in the field laboratory of Soil and Water Engineering Department, College of Agricultural Engineering and Technology, CCS Haryana Agricultural University, Hisar. The selected spacings were i) 6m x 6m, 1m x 6m and 0.5m x 0.5m for dripper and micro-tube, ii) 6m x 0.6m, 1m x 0.6m and 0.5m x 0.6m for drip-in and iii) 6m x 0.3m, 1m x 0.3m and 0.5m x 0.3m for drip tape. The operating pressure heads were 5m, 10m and 13m. The measurement of discharge for calculation of hydraulic performance evaluation measures was done by operating the system and putting the containers at 6m interval along the lateral lines. The measurement of pressure head was done with the help of mercury manometer and water manometer at up stream and down stream end of main line and lateral line. The values of different hydraulic performance evaluation measures and head loss in main line and lateral line were calculated. The values of uniformity coefficient and emission uniformity decreased for dripper and micro-tube and increased for drip-in and rip tape, as the spacing decreased. The values of uniformity coefficient and emission uniformity for all emission devices increased as the operating pressure head increased at a particular spacing. The values of coefficient of variation increased for dripper and micro-tube and decreased for drip-in and drip tape, as the spacing decreased. The values of coefficient of variation for all emission devices decreased as the operating pressure head increased at a particular spacing. The values of coefficient of manufacturing variation was maximum for drip tape and minimum for micro-tube. The values of head loss in main line and lateral line for different emission devices increased as the spacing decreased and increased as the operating pressure head increased. The head loss in the main line and lateral line also increased at a decreasing rate with discharge and the variation can be expressed with a power equation. The values of the coefficients in the power relationship between head loss and discharge were calculated for each emission device and also combined for all emission devices. The coefficient of correlation for the combined equation was 0.9871 for main line and 0.7201 for lateral line. A computer software in C++ language was developed for calculation of the hydraulic performance evaluation measures and head loss in main line and lateral line of system. The values obtained from the computer software were equal to the measured values.ThesisItem Open Access Genetic and symbiotic characterization of poly-β-hydroxybutyrate production in Rhizobium and Bradyrhizobium spp. nodulating mungbean [Vigna radiata (L.) Wilczek](CCSHAU, 2008) Sandeep Kumar; Yadav, A. S.Twenty-one WT strains of Rhizobium/Bradyrhizobium sp. (Vigna) were isolated purified and tested for their ability to form nodules on the mungbean plants. These WT strains were screened for PHB production on Beringer’s MM with Nile blue A under UV light. The two WT strains MBR 16 and MBR 25 produced high amount of PHB and these were used to isolate PHB mutants. Three types of mutants were isolated and characterized as MHt, MM and ML mutants. The MHt mutants produced highest amount of PHB, whereas ML mutants produced very low amount of PHB. The Maximum amount of PHB was found in MBR 16 MHt 1 i. e. 1.24 g/l. The antibiotic resistance pattern of parent strains and their mutants was almost same. The symbiotic effectivity of parent strains and their mutants on mugbean plants showed that the MHt mutants had higher shoot dry weight and total shoot nitrogen than the MM and ML mutants. A highly significant positive correlation was found between the amount of PHB produced and shoot dry weight and total shoot nitrogen of the munbean plants.ThesisItem Open Access Effect of time of planting and gibberellic acid (GA3) on growth and flowering of tuberose (Polianthes tuberosa L.)(CCSHAU, 2008) Sandeep Kumar; Sharma, Jeet RamThe present investigations entitled, “Effect of time of planting and gibberellic acid (GA3) on growth and flowering of tuberose (Polianthes tuberosa L.)” were carried out at the experimental orchard, Department of Horticulture, Chaudhary Charan Singh Haryana Agricultural University, Hisar during the year 2007-08. The experiment was laid out in factorial RBD design having seven planting times (last week of February to last week of May) and three gibberellic acid treatments (0 ppm, 50 ppm and 100 ppm) with three replications. Days taken for initiation and complete of sprouting of bulbs were less when bulbs were planted in month of May. The plant growth in terms of plant height, number of leaves per plant and average length of leaves were recorded maximum in 10th April planting which is statistically at par with 23rd March planting, whereas, minimum in 23rd May planting. The days taken for spike initiation, opening of first floret and 50% flowering were recorded minimum in 10th April planting, whereas, maximum in 21st February planting. The duration of flowering was recorded maximum in 10th April planting and minimum in 23rd May planting. The maximum number of spikes per plant was recorded 10th April planting which was at par with 25th April and 23rd March plantings. The maximum length of spike, length of rachis and number of florets per spike were observed in 10th April planting. In case of bulb production, the number of bulbs per plant, weight of bulbs per plant and size of bulbs (dia.) were observed maximum in 10th April planting, whereas, minimum in 23th May planting. Maximum plant height, number of leaves per plant and average length of leaves were recorded with foliar application of gibberellic acid at 100 ppm. Minimum days taken for spike initiation, opening of first floret, and 50% flowering were recorded with GA3 at 100 ppm. The duration of flowering was also recorded maximum with GA3 at 100 ppm. Maximum length of spike, length of rachis and number of florets per spike were observed with GA3 at 100 ppm. This concentration of GA3 also resulted in production of maximum number of bulbs per plant and size of bulbs (dia.) which was statistically at par with 50 ppm treatment. The weight of bulbs per plant was recorded maximum with GA3 application at 50 ppm.
