    Usage of information and communication technologies by extension personnel at KVKs in Haryana
    (CCSHAU, Hisar, 2023-05) Jyoti; Dahiya, Manju
    Information and communication technology in agriculture (ICT in agriculture), also known as e-agriculture, is developing and applying innovative ways to use ICTs in the rural domain, with a primary focus on agriculture. Farmers are sometimes hesitant to adopt new technologies because they fear losing their traditional methods of cultivation. Convincing them should be the first step in encouraging rural ICT use. The socio-demographic profile of extension personnel from all the KVKs of Haryana state reveled that majority of the respondents (56.2%) fall into the age group of 29-40 years, were males (75.0%), Subject Matter Specialists (78.7%), had a service experience of 1-5 years (37.5%), majority of the respondents were PhD with NET (97.5%) and were from the discipline of agronomy (25.0%). Cent per cent of extension personnel had availability and accessibility to ICT with them. Majority of the respondents (90.0%) had basic purpose of gaining/updating knowledge and printing/ publication (printed online), majority of the respondents utilized ICT for gaining information on nursery management with (WMS-2.63), (56.2%) utilized 1-2 GB internet per day where 31.2 percent had the extent of usage for 2-4 hours, regarding media exposure, majority of respondents (95.0%) had exposure of package of practices. Index showed that 81.8% of the extension personnel had knowledge regarding information communication technology. Majority (76.5%) of respondents from the discipline economics were using ICT (rank-I) for dissemination of knowledge followed by soil science (71.0 %) with (rank- II). Majority of the respondents found e-mausamhau krishi seva most supportive platform with (Garret score 88.97) for weather information. ―Economic constraints‖ with composite index- 82.96 (rank- I) followed by ―infrastructural and technical‖ constraints with composite index – 82.70 (rank – II) were the major constraints faced by extension personnel. It was found that the age, gender, hours of power supply of the respondents had significant correlation with acquisition of knowledge. For dissemination of knowledge also the age, gender, post held, service experience, hours of power supply of the respondents had significant correlation with solving problems (r= 0.247), demonstrating new technology (r= 0.223), imparting training (r= 0.235), giving advice to farmers (r= 0.224), preparing media (r = 0.2.18) and contacting farmers (r= 0.211). It was suggested by cent per cent of the extension personnel that there should be establishment and strengthening of ICT center, liason and access with agricultural research centers through ICT followed by access to e-external sources 97.5 percent and at village level information kiosk should be developed 8.7 percent.

    Effect of vitamin C on growth performance and haematological parameters of Catla catla Hamilton, 1822
    (CCSHAU, Hisar, 2023-05-25) Jyoti; Dahiya, Tejpal
    This study investigated the effects of different doses of vitamin C on the growth, survival, and haematological parameters of C. catla over a period of 60 days. Three different concentrations of vitamin C (500 mg/kg, 1000 mg/kg, and 1500 mg/kg) were supplemented with basal feed in three treatment groups (T1, T2, and T3) while the control group received basal feed without vitamin C supplementation. Catla fry and fingerlings were used as the experimental animals. Fortnightly measurements of growth parameters revealed that the maximum growth was observed in the T2 group, which received vitamin C at a concentration of 1000 mg/kg, while the control group exhibited the lowest growth when fed with only basal feed. Treatment T2 also showed the highest weight gain in both fry and fingerlings. The specific growth rate was higher in T2 compared to other groups. Additionally, T2 demonstrated the best feed conversion ratio and feed conversion efficiency on the 60th day. The survivability percentage was highest in T2, indicating improved survival rates compared to the control group. Furthermore, T2 showed the greatest percentage increase in length for both fry and fingerlings. Haematological parameters of the T2 group were found to be superior to other treatments and the control group, suggesting that vitamin C supplementation acted as an immunostimulant. Parameters such as haemoglobin, RBC count, WBC count, and PCV were significantly higher in the T2 group compared to the control group. Conversely, mean corpuscular volume and mean corpuscular haemoglobin were lower in the T2 group compared to the control group.
