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 nitrogen levels on wheat varieties under agri-silvi-horticultural system
    (CCSHAU, 2017) Johar, Vishal; Dhillon, R.S.
    The present investigation entitled “Effect of nitrogen levels on wheat varieties under agri-silvihorticultural system” was carried out in research area of Forestry Department, CCS Haryana Agricultural University, Hisar during 2015-16 and 2016-17 to study the effect of nutrient levels on yield attributes, yield and quality parameters of different wheat varieties (WH-1105, HD-2967, WH-711 and DPW-621- 50) in already established five year old agri-horti and agri-silvi-horti systems. The growth of eucalyptus and kinnow under both agri-silvi-horti and agri-horti system increased sharply with the advancement of age. Eucalyptus attained maximum (7.2 cm) CAI for basal diameter followed by DBH (5.1 cm) during the age of six year which shows that the eucalyptus achieved sufficient biomass during 6th year of growth. The additional dose of nitrogen (10, 20 and 30 per cent) to the recommended dose of fertilizer (RDF) in both the agroforestry based systems increased the growth, yield attributes and yield of different wheat varieties however; the difference between further additional doses of N to the RDF was nonsignificant. Among different wheat varieties, HD-2967 was found the most shade tolerant and exhibited higher plant height, number of tillers, number of spikes, spike length, number of grains per spike, grain and straw yield etc under both the agroforestry based systems. Whereas, the variety WH-711 was found be the most sensitive to shade and exhibited poor growth, yield attributes traits and yield. However, grain, straw and biological yield of different wheat varieties was found higher in agri-horti system over agri-silvi-horti system due to more competition among the annuals and perennials in agri-silvi-horti system. Different quality parameters viz. protein content, gluten content, sedimentation value, grain hardness etc. in different wheat varieties was observed higher in agri-horti and agri-silvi-horti system over sole cropping system. Higher protein content, grain hardness and grain luster were recorded in HD- 2967 while, variety WH-711 exhibited higher gluten content and sedimentation values under both the agroforestry based systems. Soil EC and pH decreased considerably under both the agroforestry based systems. However, soil organic carbon, available nitrogen, phosphorus and potassium increased significantly over the control (sole crop). After six year of experimentation the higher B:C ratio was recorded in agri-silvi-horti (2.06) followed by agri-horti (1.66) and sole cropping (1.39). Hence, agrisilvi- horti and agri-horti systems are economically viable, improve the soil health and provide nutrient security. Therefore, agroforestry based systems are eco-friendly and a way to increase the farmer’s income.
