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.

    Genetic variability and heterosis studies for morphological and fruit yield traits in okra
    (CCSHAU, Hisar, 2023-08) Shubham; Dhankhar, S. K.
    A field experiment entitled “Genetic variability and heterosis studies for morphological and fruit yield traits in okra” was conducted at Research Farm of the Department of Vegetable Science, CCS Haryana Agricultural University, Hisar during spring-summer and rainy season of 2022 using line x tester mating design with a view to study the extent of heterosis, GCV and PCV in advance inbred lines of okra and to find out correlation and path coefficients for fruit yield and its attributes. The experimental material comprised of twenty-one genetically diverse genotypes of okra involving twenty lines and one tester (HB-MS-1 Line) and standard check HBH-142. These lines and tester were crossed using line x tester mating design during spring-summer season of 2022, to produce twenty F1 crosses. Analysis of variance for different quantitative characters studied during the experimentation indicated highly significant differences among the parents, crosses and commercial check at 5% and 1% level of significance. In terms of yield per hectare, four crosses viz., HB-MS-1 X HB-20-3-4, HB-MS-1 X HB-11-3-4, HB-MS-1 HBTC-6-1-2, and HB-MS-1 x H.U showed significant positive economic heterosis over the standard check HBH-142 for yield and its contributing characters. Maximum phenotypic and genotypic variability was recorded for the trait plant height, first fruit node, fruits per plant, number of branches per plant and inetrnodal length. High estimates of heritability along with high genetic advance as percent mean was observed for plant height, first fruit node, fruits per plant, number of branches per plant and inetrnodal length. Fruit yield per plant were found to have positive correlation with with plant height, number of branches, fruit length, fruit diameter, fruits per plant, and negatively correlated with days to 50 percent flowering, internodal length, first fruit node.

    Response of nitrogen and foliar spray of nano urea in sponge gourd [Luffa cylindrica (L.) Roem.]
    (CCSHAU, Hisar, 2023-08-07) Swagat Ranjan Behera; Duhan, D.S.
    A field experiment entitled “Response of nitrogen and foliar spray of nano urea in sponge gourd [Luffa cylindrica (L.) Roem.]” was conducted at the Research Farm of the Department of Vegetable Science, CCS Haryana Agricultural University, Hisar during the spring-summer seasons of 2022 and 2023 to study the effect various nitrogen and nano urea doses on growth, yield, quality and nitrogen use efficiency of sponge gourd crop and economics of the treatments. The experiment was laid out in split plot design with three replications. The main plot treatments comprised two genotypes (Pusa Chikni and Phule Prajakta) and the subplot treatments comprised ten different nitrogen and nano urea doses [N1: RDF (50 kg N, 25 kg P2O5 and 25 kg K2O per ha); N2: Two foliar sprays of nano urea @ 2 ml/L at flowering and fruiting time; N3: Two foliar sprays of nano urea @ 4 ml/L at flowering and fruiting time; N4: 75% RDN + Two foliar sprays of nano urea @ 2 ml/L at flowering and fruiting time; N5: 75% RDN + Two foliar sprays of nano urea @ 4 ml/L at flowering and fruiting time; N6: 75% RDN + One foliar spray of nano urea @ 4 ml/L at fruiting time; N7: 50% RDN + Two foliar sprays of nano urea @ 2 ml/L at flowering and fruiting time; N8: 50% RDN + Two foliar sprays of nano urea @ 4 ml/L at flowering and fruiting time; N9: 50% RDN + One foliar spray of nano urea @ 4 ml/L at fruiting time and N10: Control]. Between the two genotypes, Pusa Chikni recorded higher values for growth parameters (vine length at 60 DAS, 90 DAS and at final harvest; number of primary branches per vine and internodal length), number of fruits per plant, fruit yield per plant, yield per hectare and crop duration, and performed better in terms of earliness with respect to days to 50 per cent flowering, days to first male and female flower opening, nodes to first male and female flower and days to first fruit harvest in both the years of study. On the other hand, Phule Prajakta registered higher values for length, diameter and average weight of fruit, quality parameters (TSS content in fruit, and nitrogen and protein content in plant and fruit) and available soil nitrogen after final harvest. Among the various nitrogen and nano urea doses, treatment N5 (75% RDN + Two foliar sprays of nano urea @ 4 ml/L at flowering and fruiting time) proved to be the best in terms of overall growth, yield and quality parameters, and nitrogen use efficiency of the crop. From economics point of view, the highest gross returns, net returns and benefit-cost ratio were realized under treatment N5 (75% RDN + Two foliar sprays of nano urea @ 4 ml/L at flowering and fruiting time) in both the years of investigation.
