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.

    Impact of biochar and organic manures on soil properties and wheat yield
    (CCSHAU, Hisar, 2023-09) Deepak Kumar; Chaudhary, Kautilya
    A field experiment entitled “Impact of biochar and organic manures on soil properties and wheat yield” was carried at research farm, Department of Soil Science, CCSHAU, Hisar Haryana. The location of experimental site was 29o16’N latitude and 75o7’E longitude in the North-West part of India. The objective of this study to evaluate the impact of biochar and organic manures in enhancing the yield of wheat and soil properties. The experiment was designed with seven treatments comprising of control + RDF, 10 t/ha FYM + RDF, 5 t/ha vermicompost + RDF, 2.5 t/ha biochar + RDF, 5 t/ha biochar + RDF, 10 t/ha biochar + RDF and absolute control with three replications in a randomized block design by keeping net plot size 2.0 m x 2.0 m and row spacing of 20 cm. The observations were noted for fifteen parameters pertaining to the physical, chemical and microbiological properties of soil including yield attributes of wheat crop. The result showed that physical properties like moisture at -33 kPa and -1500 kPa (0-15cm) (4.5 cm h-1) and soil moisture at different intervals of times (14.45 and 8.54 %) was found maximum in treatment 10 t/ha biochar + RDF, while bulk density (1.38 mg m-3) was noted minimum in same treatment. In case of chemical properties of soil treatment 10 t/ha biochar + RDF reported maximum electrical conductivity (0.44 dSm-1), available NPK (126.50, 20.6, 380.4 kg ha-1), available micronutrients {Zn (1.91 mg kg-1), Cu (1.55 mg kg-1), Fe (10.75 mg kg-1) and Mn (3.80 mg kg-1)}, However maximum organic carbon recorded in treatment consisting 10 t/ha FYM + RDF and microbiological properties like microbial count (CFU/g soil) of bacteria 32.18 x 106 and actinomycetes (27.82 x 105), soil microbial activity of Dehydrogenase 119 ug TPF g-1 24 h-1, Urease (69.48 ug N g-1 soil h-1) and Alkaline phosphatase (208.95 ug PNP released g-1 soil h- 1) and microbial biomass carbon (808.77 mg kg-1) was found maximum in treatment 10 t/ha biochar + RDF, while minimum values were recorded in absolute control. The data recorded on yield attributes such as grain yield (5300 kg ha-1), straw yield (10675 kg ha-1), test weight (42.8 g) and harvest index (33.18 %) were found maximum in treatment 10 t/ha biochar + RDF. In economic analysis treatment 5 t/ha biochar + RDF was found practically more feasible with a net return (27825 Rs/ha) and benefit cost ratio (1.36).
