    Role of social media in dissemination of agricultural innovations in Haryana
    (CCSHAU, 2018) Anil Kumar; Malik, Joginder Singh
    Social media is very important tool in farming and growing at an explosive rate, with millions of people all over the world generating and sharing content on a scale barely imaginable a few years ago. Now social media is the main form of communication around the world. There is also need of timely site specific and rapid dissemination of agricultural information. . The study was conducted in two districts of Haryana state namely, Hisar and Sirsa, from each district two blocks were selected randomly, from each block two villages were selected and from each village, fifteen farmers were selected randomly. Thus, total one hundred twenty farmers were selected and interviewed with the help of well structured schedule. The interview schedule was divided into three parts i.e. awareness, adoption and constraint. Findings of the personal profile of the respondents revealed that majority of the farmers were of middle age group (31-50 years), educated up to higher secondary, belonged to nuclear family, performed farming and had land holing up to 5 acres. Result pertaining to awareness indicated that awareness about WhatsApp and Kisan SMS Portal was more than 70 % among the respondents. Results pertaining to adoption of social media to farmers revealed that most of the farmers preferred social media for entertainment and communicating purpose rather than agricultural information. No training and education about use of social media, low level of education, people were less trusted towards social media, language and cultural barriers were the main barriers faced by the respondents. The study exposed the ground reality of use of social media which could help the extension personnel to develop the models which can make social media user friendly in communicating and sharing agricultural information.

    Synthesis, characteriztation and bioevaluation of potential agrochemicals
    (CCSHAU, 2013) Anil Kumar; Rajvir Singh
    Heterocyclic systems find wide variety of application in agrochemicals and pharmaceuticals industries. Different organic compounds like, chalcones, coumarins, pyrazoles, isoxazoles and many other heterocyclic compounds containing functionalized nitrogen and oxygen play a predominant role in agrochemicals/pesticide chemistry. They have shown versatile biological activities and have been intensively used as scaffolds for pesticide development. Keeping all this in mind synthesis of 4-[(substituted phenyl-/phenoxy) anilinomethyl-/methyl]-2H-1-naphthopyran-2-ones, 1-[4-(substituted phenyl)-3-(substituted phenyl) prop-2-en-1-ones, 2-(substituted phenoxy)-1-(substituted phenyl) ethanones, pyrazoles, isoproterenol and flavanoids have been carried out. The synthesized compounds were characterized by 1HNMR, IR and other physical and analytical data. Compounds were evaluated for their antifungal and antibacterial activity against A. awamori and S.rolfsii and Bacillus by poisoned food technique and zone inhibition method respectively. Compounds were tested at 10μg/ml, 50 μg/ml, 100 μg/ml and 200 μg/ml. Various compounds of different series exhibited very significant antifungal and antibacterial activity. It was evident from structure activity relationship (SAR) that chloro substituent at different positions in different series of compounds showed the highest toxicity and replacement of chlorine with other functionality like methyl, methoxy bromine decrease the activity significantly. The compounds found acetone needs further exploration for their possible use as agrochemicals.
