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.

    Assessment of microbial communities in rhizosphere and phyllosphere of fruit tree species during different seasons
    (CCSHAU, 2019) Dinesh Kumar; Dalal, Raj Pal
    The present investigation was carried out with the objective to access the chemical properties and microbial biomass in the rhizosphere and phyllosphere of fruit tree species during different season at CCS HAU, Hisar during 2018-19. Soil samples were collected from seven fruit tree orchards viz. mango, guava, aonla, ber, bael, jamun, sweet orange along with control (uncultivated land) from rhizospheric soil and inter row spaces at 0-30 cmdepth during summer, rainy and winter season for estimation of soil chemical properties and microbial biomass. Similarly, leaf samples were collected from the phyllosphere of all the fruit tree species and season under study for microbial biomass count. The experiment was laid out in RBD with three replications. Results revels that pH value, OC, N, P, K, Zn contents increased significantly with all the fruit orchards over control (uncultivated land). However, maximum pH, EC, OC, CN ratio, available N, P, K, Zn and Fe (8.30, 0.33 dS/m, 0.54 %, 11.63, 126.26 kg/ha, 32.24 kg/ha, 284.93 kg/ha, 2.10 ppm and 3.34 ppm) was found in aonla, sweet orange, jamun, jamun, guava, sweet orange, guava, ber and sweet orange, respectively. Highest EC, CEC, OC and available K were found in winter season but pH, EC, available N, Zn, Mn and B contents were recorded maximum in summer season.CN ratio and available P were maximum in rainy season. Inter row spaces soil had highest pH, CEC, CN ratio and Zn contents while maximum OC, Available N, P, K, Fe, Mn and B contents was observed under the canopy of fruit trees. Maximum TBC, PSB and nitrogen fixers were found in mango orchard during summer and rainy while maximum fungal count in jamun orchard during all the seasons over control. Maximum increase in actinomycetes was counted in guava during summer and winter while in mango during rainy season. In phyllosphere of different fruit tree orchards maximum TBC was observed in mango during summer, jamun during rainy, aonla and sweet orange during winter season. Highest diazotrophs were observed in aonla during summer and in jamun phyllosphere during rainy and winter season. Microbial populations and fungal count decreased by 13.06 % to 42.02 % from summer to rainy season, whereas increased by 10.80 % to 32.39 % from rainy to winter season in respect to phyllosphere of all the fruit tree species.

    Studies on fruit cracking in litchi (Litchi chinensis) cultivar early large Red
    (CCSHAU, 2016) Dinesh Kumar; Suleman Mohammed
    A field experiment entitled “Studies on fruit cracking in litchi (Litchi chinensis) cultivar Early Large Red”, was carried out at Regional Research Station (Horticulture), Buria, Yamunanagar of the Department of Horticulture, Chaudhary Charan Singh Haryana Agricultural University, Hisar during 2014. The study was carried out with two objectives i.e., finding out the suitable concentration of nutrients for controlling fruit cracking and secondly, assessing the impact of fruit cracking on economics of litchi. Three nutrients zinc sulphate (0.50, 1.00, 1.50 and 2.00%), calcium chloride (1.00, 2.00, 3.00 and 4.00%) and Borax (0.40, 0.60, 0.80 and 1.00%) were taken for treatments investigating their effects on fruit cracking in litchi over water spray and no spray (control). The experiment was carried in randomized block design with three replications. Three trees were observed per replication for different tree and fruit characters. The litchi trees were of 23 year old and the cultivar was Early Large Red. The mode of application of the nutrients at different concentrations was foliar as spray done on 15 April and 5th May, 2014. Growth characters like tree height, diameter and girth were not affected with any of the treatment. Borax @ 0.80% resulted in highest number of fruits per branch (196.1), fruit weight (21.97 g), fruit length (3.69cm), fruit yield (70.33 kg/plant), TSS content, sugar acid ratio, reducing and non reducing sugar, yield of quality fruits (2757.5 kg per acre), gross returns (Rs.228453) and net returns (Rs. 177442) per acre. This treatment also resulted in lowest acidity, cracked fruit yield (196.4 kg per ace), net loss of Rs. 7881 per acre (3.34%), lowest fruit cracking (3.57, 4.18, 5.20 and 6.66%) at seven days intervals, lowest cost of production of Rs. 17.27 per kg. Calcium chloride at 1.00 % resulted in highest firmness (2.57 kg/cm2) but this nutrient was performed better to enhance the shelf life (7.7 days) at 2.00%. Treatment ‘no spray’ (control) resulted in highest cracked fruit yield of 680.4 kg/acre. The net loss in terms of per cent was highest in no spray (control) i.e. 14.53 (Rs. 27217 per acre). The benefit per rupee invested (b: c ratio) i.e. 4.09 was found maximum with Borax @ 0.80% followed by 0.40% (4.05), and 0.60% (4.01) with the same nutrient. Conclusively, foliar spray of Borax at 0.80 per cent concentration was found most suitable for controlling the fruit cracking in litchi cultivar Early Large Red as well as in terms of remuneration.
