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 biofertilizers in combination with nitrogen, phosphorous and organic manure on growth, yield and quality of strawberry cv. Winter Dawn
    (CCSHAU,HiSAR, 2020-08) Reddy, Gajjala Chandra; Goyal, R.K
    A field experiment entitled “Effect of biofertilizers in combination with nitrogen, phosphorous and organic manure on growth, yield and quality of strawberry cv. Winter Dawn" was conducted during the year 2017-18 and 2018-19 at hi-tech greenhouse of the Department of Horticulture, CCS Haryana Agricultural University, Hisar. The investigation composed of three experiments viz., (i) effect of biofertilizers in combination with nitrogen on growth, yield and quality of strawberry, (ii) effect of biofertilizers in combination with phosphorous on growth, yield and quality of strawberry and (iii) effect of organic manure in combination with biofertilizers on growth, yield and quality of strawberry. The experiment-I comprised of four levels of nitrogen, i.e., 0, 80, 100 and 120% recommended dose of nitrogen (RDN) and two biofertilizers viz., Azotobacter and Azospirillum. Nitrogen levels and biofertilizers in combination had significant influence on growth parameters such as plant height, spread, number of leaves, crown diameter and fresh and dry weight of plants. The maximum fruit yield parameters and quality traits were recorded with 100% RDN along with biofertilizers. The leaf NPK content was recorded higher in 120 and 100% RDN along with biofertilizers than control treatment. The experiment-II comprised of four levels of phosphorous, i.e., 0, 80, 100 and 120% recommended dose of phosphorous (RDP) along with two biofertilizers, i.e., vesicular- arbuscular mycorrhiza (VAM) and phosphate solubilizing bacteria (PSB). All the possible combinations of phosphorous and biofertilizers were found to have significant influence on vegetative growth, yield and quality parameters of strawberry. The minimum number of days taken to first flowering, maximum fruit weight, size and fruit yield per plant were recorded with 100% RDP along with VAM. TSS and ascorbic acid were noted maximum with combined application of 120% RDP and biofertilizers. The leaf NPK content was significantly higher in 120% RDP along with biofertilizers than the control treatment. The experiment-III comprised of nine treatments, viz., T1: Sand: FYM (3:1), T2: Sand: FYM (2:1), T3: Sand: Vermicompost (3:1), T4: Sand: Vermicompost (2:1), T5: Sand: FYM (3:1) + Azotobacter, T6: Sand: FYM (2:1) + Azotobacter, T7: Sand: Vermicompost (3:1) + Azotobacter, T8: Sand: Vermicompost (3:1) + Azotobacter and T9: Control (Sand). The results indicate that manure in combination with Azotobacter treated plants had better vegetative growth, yield and quality than the control.
