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 cutting management and phosphorus fertilization on forage yield, quality and seed yield of multicut oat (Avena sativa L.)
    (CCSHAU, 2017) Monika; Sheoran, R.S.
    The field experiment entitled “Effect of cutting management and phosphorus fertilization on forage yield, quality and seed yield of multicut oat (Avena sativa L.)” was conducted during the rabi season of 2016-17 at the Forage Research Farm of Chaudhary Charan Singh Haryana Agricultural University, Hisar with the objective to study the effect of cutting management and phosphorus fertilization on forage yield, seed production, quality and economics of different treatments for oat. Treatment combinations comprised of eight cutting management treatments i.e. C1 (Seed to Seed), C2 (Fodder at 50% flowering), C3 (Fodder 60 DAS- Seed), C4 (Fodder 70 DAS- Seed), C5 (Fodder at 80 DAS- Seed), C6 (Fodder 60 DAS- Fodder at 50% flowering), C7 (Fodder at 70 DAS- Fodder at 50% flowering), C8 (Fodder 80 DAS- Fodder at 50% flowering) and four levels of phosphorus i.e. control, 20, 40 and 60 kg P2O5/ha. The experiment was laid out in split plot design and replicated thrice. The soil of the experimental field low in available nitrogen (161 kg N/ha, medium in available), phosphorus (12 kg/ha, medium in availibity), K (252 kg/ha, slightly alkaline in reaction having pH 7.8). The results indicated that the highest fodder and dry matter yield was obtained when only one cut of fodder was taken at 50% flowering stage and it was statistically at par for green fodder yield with treatment where first cut for fodder was taken at 80 DAS and second cut at 50% flowering stage. Harvesting of fodder at 80 DAS gave significantly higher forage yield and seed yield than the harvesting at 60 or 70 DAS. Contrary to this, the straw yield and biological yield were significantly higher in the treatment when the crop was raised purely for seed purpose. Under dual system, delay in first cut i.e. from 60 to 80 DAS resulted in a significant increase in fodder yield, seed yield, crude protein yield and net returns over the earlier cuttings. Every incremental dose of applied phosphorus resulted in a significant improvement in forage, seed and straw yield as well as the quality parameters and nutrient uptake over the lower doses. Harvesting of fodder at 50% flowering stage only gave the highest net returns and B: C ratio, whereas, under dual system, maximum net returns as well as B: C ratio was realized when first cut was taken at 80 DAS and then the crop was left for seed purpose. Application of 40 kg P2O5/ha also resulted in the higher forage and seed yield along with maximum net returns.
