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.

    Evaluation and characterization in marigold
    (CCSHAU, 2013) Choudhary, Mahesh; Beniwal, B.S.
    The present experiment was conducted at Experimental Orchard of the Department of Horticulture, CCS Haryana Agricultural University, Hisar during winter seasons of 2011-12 and 2012- 13 on thirty genotypes of both African and French marigold to estimate the genetic variability, heritability, genetic advance and varietal characterization. The observations were recorded on growth, flowering and yield parameters. The analysis of variance revealed that the mean sum of squares due to genotypes were highly significant for all the characters studied, indicating a wide range of variability in the material investigated. The highest flower yield was observed in genotype Hisar Jaffri-2 followed by MGH-09-271 and MGH-09-276, while it was lowest in Hisar Beauty. The high GCV and PCV values were observed for fresh and dry weight of plant, number of secondary branches per plant, number of buds per plant and number of flowers per plant. Heritability in broad sense and genetic advance as per cent mean were higher for fresh weight of plant, dry weight of plant, number of flowers per plant, number of buds per plant and number of secondary branches per plant. Association analysis revealed high significant positive correlation of flower yield per plant with number of secondary branches per plant, number of buds per plant, number of flowers per plant, dry weight of plant, fresh weight of plant, fresh weight of flower, dry weight of flower, plant spread, flower diameter, stem diameter, duration of flowering and days taken to first flower opening, indicating selection of these characters for crop improvement and breeding strategies. Path analysis depicted that number of flowers per plant had the highest direct and positive effect on flower yield per plant, closely followed by fresh weight of flower, flower diameter, dry weight of flower and dry weight of plant. Based on D2 values, all the thirty genotypes were grouped into six clusters in both the years, i.e., 2011-12 and 2012-13, indicating the presence of considerable amount of genetic diversity among the genotypes under study. On the basis of morphological characters, the marigold genotypes were characterized and categorized effectively. The plant growth habit, branching habit, leaflet shape, leaf colour, stalk shape, disc floret, floret colour, etc., were the key characters, therefore, can be used as morphological descriptors for the varietal identification in marigold.

    Response of biofertilizers on growth, flowering and yield of chrysanthemum
    (CCSHAU, 2013) Anop Kumari; Goyal, R.K.
    The present investigation entitled “Response of biofertilizers on growth, flowering and yield of chrysanthemum” was conducted in the screen house of the Department of Horticulture, CCS Haryana Agricultural University, Hisar during the year 2011-12 and 2012-13. The investigation composed of three experiments viz., (i) response of biofertilizers in combination with nitrogen on growth and flowering of chrysanthemum (four levels of nitrogen, i.e., 0, 10, 20 and 30 g/m2 and two biofertilizers viz., Azotobacter and Azospirillum), (ii) response of biofertilizers in combination with phosphorous on growth and flowering of chrysanthemum (four levels of phosphorous, i.e., 0, 10, 15 and 20 g/m2 and two biofertilizers, i.e., PSB and mycorrhiza) and (iii) response of single and coinoculation of PGPR on growth and flowering of chrysanthemum (three strains of Bacillus viz., SYB101, SB155 and SB127 and three strains of Pseudomonas, i.e., WPS73, CPA152 and P20). All the possible combinations of nitrogen levels and biofertilizers were found to have significant influence on growth, flowering and yield parameters of chrysanthemum. The minimum number of days taken to first flowering, maximum flowering duration, flower size, number of flowers per plant, flower yield per plant and number of suckers per plant were recorded with nitrogen 20 g/m2 along with Azospirillum. An increase in nitrogen content was noted with increased application of nitrogen, whereas, phosphorus and potassium content of plant decreased. Phosphorus 15 g/m2 along with PSB was found most effective for reduced number of days taken for first flowering, longest flowering duration, maximum number of flowers per plant and flower yield per plant as well number of suckers per plant. Nitrogen and phosphorus content of plant increased significantly with increasing levels of phosphorous, and the maximum content was observed with phosphorous 20 g/m2. Different strains of Bacillus and Pseudomonas significantly influenced the observed parameters of chrysanthemum. The results indicate that Bacillus strain SB127 and Pseudomonas strain CPA152 were found potent in increasing all growth, flowering and yield parameters. The SB127 + CPA152, SB155 + CPA152 and SB127 + P20 combinations of Bacillus and Pseudomonas strains showed best results in chrysanthemum.

    Resource conservation studies in gladiolus
    (CCSHAU, 2013) Zehra Salma; Ahlawat, V. P.
    Resource conservation studies in gladiolus were carried out at Precision Farming Development Centre, Department of Horticulture and Biocontrol laboratory, Department of Microbiology, CCS Haryana Agricultural University, Hisar during the years 2011-12 and 2012-13. The studies on the effect of different irrigation methods and mulching on growth, yield and quality of gladiolus revealed that raised bed with drip irrigation and mulching was found effective resulting in maximum growth and quality parameters, minimum weed intensity and conserving soil moisture throughout the growth period in gladiolus. The efficacy of biofertilizers for nutrient management revealed that application of Pseudomonas strain (WPS73) with 75% RDF followed by Azotobacter chroococcum (Mac27) with 75% RDF was beneficial for growth and quality of gladiolus. Incompatibility was observed in coinoculation of Azotobacter chroococcum (Mac27) and Pseudomonas strain (WPS73), which resulted in complete mortality of plants when applied in combination. The study on dynamics of biofertilizers in combating biotic stress revealed that four strains HWM13, HCS2 from Pseudomonas species and RSD8, NNY19 from Bacillus species showed antifungal activity under plate conditions. Rhizobacterial strain HCS2 of Pseudomonas species showed its positive effect in suppressing Fusarium wilt disease caused by fungal pathogen Fusarium oxysporum f. sp. gladioli in gladiolus under pot conditions.

    Genetic characterization in vegetable cowpea [vigna unguiculata (L.) walp.]
    (CCSHAU, 2012) Nancee; Rana, M.K.
    The extent of genetic variability for quantitative traits was assessed in 46 genotypes of cowpea along with nature and magnitude of association between pod yield and its component traits. Also, the magnitude of genetic divergence of genotypes was assessed. The present studies revealed that leaf form, flower colour, pod colour and plant growth habit were found to be important diagnostic characters for varietal identification in cowpea. Analysis of variance revealed significant difference among the genotypes for all the characters. High GCV and PCV coupled with high heritability and genetic advance were recorded for length of pod, weight per pod, number of pod per plant, pod yield per plant, number of seeds per pod, plant height at final harvest and harvest index. Also, positive association was observed with weight per pod, number of pods per plant, length of pod and breadth of pod. Path analysis revealed that weight per pod, days to last picking and harvest index had considerable influence on pod yield. Mahalanobis D2 statistics indicated considerable diversity and genotypes were grouped into eight clusters. The cluster IV was the largest with 15 genotypes followed by cluster VII with 11, cluster III had 6, cluster I, V, VI and VII comprised 3 genotypes, and cluster II had 2 genotypes. Maximum inter cluster distance was observed between V and VIII, indicating maximum divergence among genotypes. The highest intracluster distance was recorded for cluster V (5.14). The highest contribution to the diversity was recorded by number of seeds per pod and plant height at final harvest.
