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 seed size, spacing and nitrogen on seed potato production cv. Kufri Bahar
    (CCSHAU, 2012) Pawan Kumar; Bhatia, A.K.
    The experiment entitled“Effect of seed size, spacing and nitrogen on seedpotato production cv. Kufri Bahar.” was conducted at Research Farm of the Department of Vegetable Science, CCS Haryana Agricultural University, Hisar during winter season of 2009-10. The experiment comprising of three seed size (25-50 g, >50-75 g and >75-100 g), three plant spacing (60x10, 60x15 and 60x20 cm) and two nitrogen level (100 and 125 N kg/ha) was laid out in a randomized block design with three replications keeping net plot size 3.6x3.0 m. Ten competitive plants were selected randomly from each experimental treatment to record data on various parameters, which were influenced significantly by different seed size, plant spacing and nitrogen levels. The per cent plant emergence, plant height, leaves/stem, leaf area index, number of tubers up to 25 g, >25-50 g and >50-75 g grade, total numberof tuber, weight of tuber >25-50 g and >50-75 g grade were statistically higher with seed size >75-100 g tubers. However, the value for number of stems per hill, leaves weight per hill, stem weightand weight of foliage, number of tubers per plot >75 g grade, weight of tubers up to 25 and >75 g and total tuber yield was maximum with >50-75 g seed size tubers. Different plant spacing exhibited significant difference for growth and yield parameters. The maximum value for plant height, stem/hill, leaves/stem, leaf area index , leaves weight, stem weight, weight of foliage, number of tubers >50-75 g and >75 g grade, total number of tubers, weight of tubers up to 25 g, >25-50 g >50-75 g, >75 g grade and total tuber yield were maximum with 60x20 cm plant spacing. However, per cent plant emergencewas found maximum with plant spacing 60x15 cm and number of tubers up to 25 g and >25-50 g grade tubers per plot were found maximum with plant closest spacing of 60x10 cm. Effect of nitrogen level showed remarkable variation for growth and yield parameters except per cent plant emergence. Significantly highest value was registered for plant height, stem/hill, leaves/stem, leaf area index, leaves weight, stem weight, weight of foliage, numberof tubers up to 25 g, >25-50 g, >50-75 g and >75 g, total number of tubers, weight of tubers up to 25 g, >25-50 g >50-75 g and >75 g grade, total tuber yield with nitrogen 125 kg/ha. However, plant emergence found maximum with nitrogen 100 kg /ha. Kufri Bahar produced highest total tuber yield 437.14 q/ha when >50-75 g seed size tubers were planted at a spacing 60x20 cm and nitrogen level 125 kg/ha which was followed by seed size >75-100 g, plant spacing 60x15 cm and nitrogen level 100 kg/ha.
