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.

    Response of rice to N, P & K levels in rice-wheat cropping system on farmer field
    (2005) Amandeep; Rinwa, Ran Singh
    A field experiment was conducted during kharif-2004 on a sandy loam to sandy clay loam soil, low in available nitrogen, high in available phosphorus & potash at farmer’s fields in Karnal and Ambala districts of Haryana state. The experiment consisting of combination of five treatments viz., N0P0K0, N150, N150P60, N150K60 and N150P60K60 kg ha-1 was laid out in RBD design with twelve replications. The experiment was carried out with the objectives of to study the effect of N, P & K on growth, yield & yield attributes, nutrient uptake and their use efficiency in rice including the economics of different treatments & status of soil. The effect on number of hill was not affected by any of fertilizer treatments. The number of tillers increased with the age of crop up to 60 days after transplanting (DAT) and thereafter, slight reduction was recorded at 90 DAT. Dry matter accumulation increased with the advancement of crop stages and maximum increase was observed during 60-90 DAT. The yield and yield attributes were significantly affected by N150 P60 K60 levels. The maximum number of panicles hill-1 and number of spiklets panicle-1 were recorded with the application of NPK. The NPK level produced significantly higher number of grains per panicle and maximum 1000-grain weight was recorded with NPK which was superior over control. Application of N150 P60 K60 fertilizer levels gave significantly higher grain, straw and biological yields at all locations and harvest index was significantly higher at Ambala & in average of sub zone, except at Karnal. The nutrient uptake in grain and straw was highest with NPK levels. The response of N, P & K was in order of N>P>K at N150 P60 K60 levels. The net returns and B:C was higher with application of NPK levels. The O.C. and available N was either maintained or slightly reduced and available P & K declined after harvest of crop from their initial respective status of soil.
