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.

    Adoption status of onion growers regarding pre and post-harvest management practices
    (CCSHAU,HiSAR, 2020) Amit; Bharat Singh
    The study was conducted in Mewat and Ambala districts of Haryana state during 2018-2020. These districts have maximum area under onion cultivation. A total number of 120 onion growing farmers constituted the sample of the study. The information about respondent`s socio-personnel traits, knowledge level pertaining to pre and post-harvest management practices of onion, adoption level of pre and postharvest practices and constraints encountered by them in adoption of pre and post-harvest management practices were collected with the help of pre tested structured interview schedule. The study revealed that transportation, proper harvesting, maturity index, irrigation, weed control measures, time of sowing in nursery and time of transplanting were the practices about which majority of farmers had correct knowledge. Stop irrigation before 15 days of harvesting, insect pests and their control measures, curing, storage and diseases and their control measures were the practices about which majority of farmers had incorrect or insufficient knowledge. The overall knowledge level of respondents about pre and post-harvest management practices was medium to high since 85 per cent of respondents belonged to these categories and only 15 per cent farmers belonged to low knowledge category. The study also showed that transportation, maturity index, irrigation, time of sowing in nursery, time of transplanting, weed control measures and recommended seed rate were fully adopted practices by onion farmers whereas they had least adopted or not adopted the practices like diseases and their control, storage, curing, stoping irrigation before 15 days of harvesting, grading, insect pests and their control measures and precooling. The overall adoption level of pre and post-harvest management practices of onion growers was also found moderate to high since 80 per cent of the onion growers belonged to said categories. Regarding constraints faced by onion growers included lack of finance for purchase of inputs, high price of pesticides, lack of remunerative MSP policy by government, middleman malpractices, unskilled labour, no crop insurance coverage, lack of proper knowledge regarding post-harvest management practices as well lack of knowledge of these among field functionaries were very serious constraints experienced by the farmers. The government should seriously look into the problems faced by the onion growers and necessary steps or actions should be taken to formulate remunerative MSP policy and its implementation, affordable prices of insecticides and pesticides and organization of sufficient and proper training for both field functionaries and farmers to make the enterprise profitable and sustainable.

    Line x Tester analysis (fixed effect model) for yield and its components in fieldpea (Pisum sativum L.)
    (CCSHAU,HiSAR, 2021-08) Amit; Yadav, Rajesh
    Recombinant breeding is the most appropriate approach to combine various desirable attributes in self-pollinated crops. Genetic variability parameters, combining ability and heterosis were studied for days to flowering, maturity, primary and secondary branches per plant, nod per plant, height of first pod, plant height, pods per plant, seeds per pod, 100-seed weight, biological and seed yield per plant and harvest index in fieldpea (Pisum sativum L.) using line x tester design involving nine lines, three testers and their 27 crosses. The results revealed significant differences among the parents and hybrids for almost all the traits implying presence of adequate variability. Significant interaction between lines and testers was for almost all the traits expressed existence of sufficient amount of heterosis for most of the characters studied. Narrow differences between PCV and GCV of different traits indicated lesser influence of environment on the expression of these traits. Low heritability coupled with low genetic advance were observed for most of traits expect days to maturity, height of first pod and plant height suggesting that these traits are genetically controlled by non-additive gene action. The lines HFP 715 and Aman and the tester GP02/1108 and the crosses HFP 715 x GP02/1108, Aman x GP02/1108 and Pant P-243 x HFP 1426 were observed to be the best general and specific combiners, respectively for seed yield and its components. The σ2SCA >σ2GCA in almost all the traits indicating control of non-additive gene effects. High manifestation of heterobeltiosis for seed yield was evidenced by the superiority of 24 out of 27 crosses over better parent. High heterosis was observed in the cross HFP 715 x GP02/1108 followed by IPF 14-16 x GP02/1108, IPF 14-16 x HFP 1426, DDR-23 x HFP 1426, DDR-23 x GP02/1108 and Aman x GP02/1108 for yield and its attributes. The lines and crosses exhibited superiority in the present study can be exploited for isolating desirable transgressive segregants in advanced generations in future fieldpea improvement programmes.
