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.

    Effect of organic fertilizers on various wheat varieties under Casuarina (Casuarina junghuhniana) based agroforestry system
    (CCSHAU, Hisar, 2023-07-12) Shivam; Arya, Sandeep
    The present investigation entitled “Effect of organic fertilizers on various wheat varieties under a casuarina (Casuarina junghuhniana) based agroforestry system” was conducted at the Department of Forestry, CCS Haryana Agricultural University, Hisar, during the Rabi season of 2022- 23 to investigate the effect of organic fertilizers under Casuarina plantation planted at spacings of 5 × 3 m on growth, physiology and yield attributes of wheat crop. During the research period, the casuarina tree’s growth parameters increased by 0.4 m in height, 1.85 cm in girth and 0.2 m in crown spread. With varied levels of organic fertilizers, a significantly higher rise in soil organic carbon, available N, P, K and DTPA extractable micronutrients (Zn, Fe, Cu and Mn) was observed under casuarina based agroforestry system than in control (devoid of trees). At all the soil depths, the moisture content was discovered to be lower under casuarina based agroforestry system than in the control. The reduction in light available to understory crops ranged from 54.5 to 59.3%. The temperature was marginally lower in the casuarina plantation than in the control, but the relative humidity was higher during the crop growth period. Except for relative stress injury (%), nitrogen balance index (NBI), chlorophyll index (CHI) and canopy temperature depression (CTD, °C), the various growth, physiological and yieldattributing parameters of different wheat varieties under study were significantly higher in sole wheat crop than under casuarina based agroforestry system. Wheat variety WH 1270 had the highest test weight, dry matter accumulation (g/mrl), grain yield (t/ha) and harvest index (%) under casuarina based agroforestry system. Whereas wheat variety WH 1142 exhibited the greatest percentage reduction in grain yield (35.31%) over control followed by WH 1270 (34.7%), WH 1124 (34.49%) and WH 1184 (34.02%).Variety WH 1142 was shown to be particularly vulnerable to shade and to have inferior growth, yield-contributing characteristics and yield (as the biological yield was lowered by 33.6% and grain production was reduced by 35.31%) under casuarina based agroforestry system. Wheat varieties showed the greatest response to treatment T1 (RDN), which can be seen in the comparative results of nitrogen balance index, chlorophyll index, yield and yield attributes of wheat crop with treatment T1 (150 kg/ha RDN through inorganic fertilizers).
