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 vesicular arbuscular mycorrhizae and phosphorus levels on soil properties and yield of wheat in Aridisol and Inceptisol soils of Haryana
    (CCSHAU, Hisar, 2023-06) Aarti; Sheoran, Hardeep Singh
    A screen house experiment entitled “Impact of vesicular arbuscular mycorrhizae and phosphorus levels on soil properties and yield of wheat in Aridisol and Inceptisol soils of Haryana” was carried out during Rabi season 2022-2023 in Screen House, Department of Soil Science, CCS Haryana Agricultural University, Hisar. A pot experiment was conducted using wheat (WH-1105) as test crop and a total of 16 treatments with four levels of phosphorus (0, 30, 45 and 60 kg/ha), each with and without VAM inoculation. The experiment was laid out in three factorial CRD design with three replications. In both light and heavy soils, among different levels of applied phosphorus, 60 kg/ha phosphorus application recorded highest value for grain yield (11.51g/pot), straw yield (13.08 g/pot), NPK uptake in grain (182.0, 65.7, 63.5 mg/pot, respectively), and straw (72.3, 28.7, 178.4 mg/pot, respectively), alkaline phosphatase activity (221.22 µg PNP/g soil/h) and dehydrogenase activity ( 68.55 µg TPF/g of soil/24 h). However, available N and K content in soil after wheat harvest showed a declining trend, while P concentration increased with increase in phosphorus levels. With VAM inoculation percent increase in grain yield (6.24), straw yield (4.42), N uptake in grain (12.22), and straw (15.86), P uptake in grain (14.90), and straw (19.00), K uptake in gran (12.39), and straw (10.39), alkaline phosphatase activity (8.01) and dehydrogenase activity (6.84) showed an increasing treand as compared to uninoculated. The combine application of phosphorus and VAM had more beneficial and significant effect over alone application of P or VAM in improving wheat yield and soil physico chemical and biological properties. VAM has significant effect in improving the availability of micronutrients (especially Zn and Fe), which have antagonistic effect with phosphorus. Soil chemical properties like pH, EC and soil organic carbon were not significantly affected by their combined application. However VAM, significantly improved the soil physico-chemical properties. The maximum value of grain and straw yield was recorded by application of P @60 kg/ha along with VAM inoculation (11.82g/pot), which was found to be at par with grain yield of applied P@45 kg/ha with VAM inoculation (11.74g/pot). Overall it can be concluded that heavy soils applied with 45 kg/ha phosphorus with VAM performed best in respect to yield and improving soil chemical and biological properties of soil.
