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 Biochemical and physiological changes in seed quality of Wheat [Triticum aestivum (L.) em. Thell] under different salinity levels(CCSHAU,HiSAR, 2019) Hemender; Mor, V. SThe present study was planned to standardize the hydropriming protocol and evaluate the effect of different seed priming treatments on seed quality and plant growth of three wheat varieties under different salinity levels. Results revealed that mean sum of squares were significant for all the factors studied indicating sufficient magnitude of variations. The work on standardization of hydropriming indicated that volume of water and duration of soaking significantly influenced the seed performance and highest germination and vigour was observed at 12 hours soaking duration in equal volume closely followed by 8 hours with double volume and a decline was observed at 16 and 20 hours. The seedling vigour at 25°C increased as compared to 20°C level but, germination percentage showed a minor reduction at 25°C. Seed priming with saline water was found to produce a negative effect on seed quality as it showed a reduction in all the parameters with increase in salinity of the priming solution as compared to simple water. Low (2 and 4 dSm-1) and moderate (6 and 8 dSm-1) salinity adversely affect the speed of germination and early seedling growth but not showing much effect on the germination percentage, but, salinity above 8dSm-1 also decreased the percent germination. The salinity also produced detrimental effects on plant morphological development and yield. All the plant growth and yield attributing parameters reduced with rise in salinity and highest effect was shown on tillering at high salinity levels which resulted in 90% decrease in grain yield at 12 dSm-1 as compared to control. Among the genotypes, KRL 213 showed its salt tolerance potential and performed better than WH 1105 and WH 1124 at high salinity whereas, WH 1124 showed some sort of tolerance at moderate level of salt stress. Seed priming with different chemical agents proved to be beneficial under saline conditions as it improved the germination and seed vigour as compared to unprimed seed. Priming with CaCl2, salicylic acid and GA3 showed the salinity mitigating effect and highest values for most of the seed vigour parameters and plant growth and yield traitsThesisItem Open Access Studies on Seed Quality Enhancement and Storability in Fennel (Foeniculum vulgare)(CCSHAU,HiSAR, 2019-09) Suryapal Singh; Sangwan, V.P.SThe present study entitled “Studies on Seed Quality Enhancement and Storability in Fennel (Foeniculum vulgare)” was carried out in the Laboratory of Department of Seed Science and Technology, CCS Haryana Agricultural University, Hisar for a period of 18 months during 2017-2019 under ambient conditions on cultivar Hiasr Swarup (HF 33) of fennel to ascertain the influence of seed pelleting and priming on seed quality and also the combined effect of both on the storability of fennel seeds. The present research comprised of the three different experiments, which were laid out in Complete Randomized Design (CRD) and consisting of 7 pelleting and 15 priming treatments with three replications to assess the different physiological and biochemical parameters in fennel. In the first experiment, fennel seeds responded well to different pelleting treatments. The physiological parameters (standard germination, speed of emergence, seedling length, seedling dry weight and vigour indices) and biochemical parameters (catalase, peroxidase, dehydrogenase and superoxide dismutase activity) increased on pelleting with Captan @3 g/kg + Imidacloprid@ 2g/kg followed by neem leaf powder (100 g/kg seeds), whereas, electrical conductivity was recorded minimum in above pelleting treatments. In the second experiment, priming with Trichoderma viride (8g/kg seed) or KNO3 (1%) significantly improved the physiological and biochemical parameters, which increased significantly over the control, apart from electrical conductivity. In the third experiment, the seed quality relating to physiological and biochemical traits decreased with advancement in storability except for electrical conductivity. Better retention of seed quality characters viz., standard germination, speed of emergence, seedling dry weight, vigour indices along with biochemical characters was observed in the seeds pelleted with Captan (3 g/kg) + Imidacloprid (2 g/kg) followed by KNO3 (1%) and neem leaf powder (100 g/kg seeds) after 18 months of storage (except seedling length and seed vigour index-I). The minimum EC was recorded in seeds primed with Trichoderma viride (8g/kg seed), followed by KNO3 (1%) and seeds pelleted with Captan @3 g/kg + Imidacloprid @2 g/kg. Hence, it can be concluded that in order to maintain better seed quality of fennel during storage, seed pelleting proved superior over seed priming that ought to be given as pre-sowing treatment not as pre-storage treatment.ThesisItem Open Access Seed quality assessment in natural and artificially aged seed of fenugreek (Trigonella foenum-graecum L.)(CCSHAU, 2019) Sunil Kumar; Sangwan, V.P.S.The present study entitled “Seed quality assessment in natural and artificially aged seed of fenugreek (Trigonella foenum-graecum L.)” was carried out in the Department of Seed Science & Technology at CCS Haryana Agricultural University, Hisar (Haryana). The experiments were laid out in factorial Complete Randomized Design (CRD) and Randomized Block Design (RBD) for laboratory and field parameters, respectively on six genotypes of fenugreek viz., HM-57, HM-103, HM-273, RMT-361, FGK-49, FGK-80. The present investigation was carried out in three different experiments to meet out the objectives of study. In the first experiment, To assess the seed quality during natural ageing at 3 months interval up to 18 months and check physiological and biochemical parameters viz., standard germination, seedling length, seedling dry weight, vigour index-I & II, viability test (Tz %) catalase (CAT) peroxidase (POX), superoxide dismutase (SOD), dehydrogenase enzyme activity parameters were decreased significantly with the advancement of natural ageing of seeds whereas, electrical conductivity of seeds leachates increased with the advancement of time. The field parameters viz., seedling emergence index and seedling establishment were also decreased significantly with the advancement of time whereas, mean emergence time increased with the passage of time. In the second experiment, to study the physiological and biochemical change after accelerated ageing of all six genotypes of fenugreek. Effect of artificial ageing was more as compared to natural ageing to degradation fresh seed. In the third experiment effect of priming on marginal seed of natural and artificial aged seed of all six genotypes of fenugreek. Seed priming treatments viz., T0: Control, T1: hydro-priming followed by dry dressing with thiram @ 0.25%, T2: Hydration with GA3 (50 ppm), T3: Hydration with PEG (6000), T4: Hydration with KNO3 (0.5%), T5: 2% CaCl2 were analyzed to identify the suitable priming treatment. Among various priming treatments „T2‟- hydration with GA3 @ 50 ppm followed by „T1‟-Thiram performed best to enhance all the seed vigour and viability characteristics and to lower down the electrical conductivity of naturally and artificially aged seed of fenugreek. The seed quality improvement through seed priming was noticed more in marginal seed i.e. artificial aged seed. Among the different genotypes, maximum enhancement was observed in FGK-80 followed by FGK-49 whereas, minimum enhancement was observed in genotype HM-57 during the study. In conclusion, the present study revealed that fenugreek seed lose its viability and vigour with the advancement of storage time and seed priming with GA3 @ 50 ppm and thiram can be used as an effective tool to enhance vigour and viability of seed.
