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 low plastic tunnels, transplanting dates and mulching on yield and quality of tomato
    (CCSHAU, 2018) Ansul; Batra, V.K.
    The present investigation entitled “Effect of low plastic tunnel, transplanting dates and mulching on yield and quality of tomato production”was conducted at Research Farm, Department of Vegetable Science and Laboratory work was carried out at Department of Biochemistry, CCS Haryana Agricultural University, Hisar during Rabi of 2014-15 and 2015-16. A field experimentcomprising of two types of tunnels i.e. low tunnel and without tunnel, three dates of transplanting (30th November, 20th December, 10th January,) and three types of mulching materials (black polyethylene, white polythene and control) were laid out in three factorial RBD design with three replications, thus making a total of eighteen treatment combinations, from the various parameters. The results of the study clearly indicated that the plant height and number of branches plant-1 were recorded significantly higher when seedlings were transplanted on 20th December under plastic low tunnel with black polyethylene as mulching material. The minimum number of days to 50% flowering and days to first harvesting were observed in case where the crop transplanted on 10th January under low tunnel using black polyethylene mulch. The maximum number of days taken to last harvesting was recorded when seedlings were transplanted on 30th November under low tunnel with black polyethylene mulch. Moreover, the number of flower per inflorescence, number of inflorescence plant-1, fruits plant-1, fruit weight and early fruit yield q/ha and marketable fruit yield q/ha was recorded maximum under plastic low tunnel when the crop was transplanted on 20th December with black polyethylene mulch while minimum unmarketable yield was observed when seedlings were transplanted under plastic low tunnel on 30th November using black polyethylene as mulch. When the crop was transplanted on 30th November under plastic low tunnel with black polyethylene mulch recorded the minimum weed intensity and dry weight at harvesting stage. In case of qualitative parameters, significantly higher pericarp thickness, acidity, ascorbic acid content and total soluble solids were recorded in the treatment where the seedlings were transplanted on 30th November under plastic low tunnel with black polyethylene as mulch and it was observed that all the qualitative characteristics of the crop (pericarp thickness, acidity, ascorbic acid and total soluble solids) were significantly decreased with delay in planting while the maximum fruit firmness was recorded when tomato seedlings were transplanted on 20th December under low plastic tunnel using black polyethylene as mulching material.The economics of various treatments with benefit to cost ratio and net return was also calculated and the maximum benefit to cost ratio (2.17: 1) and net return (Rs. 278388/ ha) was obtained from tomato crop transplanted 20th December under plastic low tunnel with black polyethylene mulch. From the study, it is concluded that the tomato crop planted on 20th December under low tunnel using black polyethylene as mulching material gave the best results.
