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 summer greengram (Vigna radiata L.) varieties to integrated nutrient management
    (CCSHAU, Hisar, 2021-09) Akshay; Satyajeet
    The present study entitled “Response of summer greengram (Vigna radiata L.) varieties to integrated nutrient management” was carried out at Research Farm of CCS Haryana Agricultural University, Regional Research Station, Bawal, Rewari (Haryana) during the summer, 2020. The experiment was comprised of three varieties viz., V1- MH-421, V2- MH-318 and V3- SML-668 as main plot treatment and four different fertility levels viz., T1 - Control, T2 - 100% RDF (20:40:0 kg/ha NPK), T3 - 75% RDF (inorganic) + 25% N/ha (FYM) + seed treatment (Rhizobium + PSB) and T4 - 50% RDF (inorganic) + 50% N/ha (FYM) + seed treatment (Rhizobium + PSB) as sub plot treatments. Experiment was laid out in split plot design with four replications. Based on the research investigation, it was found that both varieties and fertility levels have significant effect on growth, phenology, yield attributes, yield and economics of summer greengram. Among varieties, MH-318 recorded significantly higher grain yield (1110 kg ha-1), straw yield (3020 kg ha-1), net return (52972 ₹ ha-1) and B:C (3.12) which were 16.6, 7.1, 26.43 and 16.4 per cent higher than MH-421, respectively due to higher yield attributes i.e. number of pods per plant (17.9), number of seeds per pod (10.6), pod length (8.5) and seed index (5.09) with MH-318 which was 8.5, 5.1, 7.9, 11.4 and 4.8 per cent higher than MH-421, respectively. However, it remained at par with SML-668. Decrease in number of days taken to flowering and maturity was recorded in MH-318 in comparison to MH-421. Among fertility levels application of 75% RDF (inorganic) + 25% N/ha (FYM) + seed treatment (Rhizobium + PSB) recorded significantly higher no. of pods per plant (18.1), number of seeds per pod (10.7), grain yield (1269 kg ha-1), biological yield (4664 kg ha-1), straw yield (3395 kg ha-1), net return (62743 ₹ ha-1) and B:C (3.40), which were 22, 12, 84, 59, 51, 125 and 45% higher than control, respectively. Thus, the variety MH-318 should be fertilized with 75% RDF (inorganic) + 25% N/ha (FYM) + seed treatment (Rhizobium + PSB) to obtain higher yield and economic returns of summer greengram.
