The goal of the study was to find out if farmers were more likely to use Direct Seeded Rice as a way to save resources than Puddled Transplanted Rice (PTR/transplanting method) when there was a shortage of workers during the COVID-19 lockdown. During the years 2020 and 2021, a study was done in the Haryana district of Kurukshetra on the pandemic and the problems farmers had with it. Randomly, 25 farmers from each of the four towns were chosen for the study. The 100 respondents were then interviewed using a specific interview schedule, empirical data was collected from each responder individually, and the data was then analysed using standard methods. According to the results, most of the respondents (77.50%) were in the Low to Medium category, and 22.50 percent of the farmers were in the High category for the total level of acceptance of DSR technology during the paddy season (Kharif 2020). While most farmers (87.50%) said they would adopt DSR technology at a low to medium level, only 12.50% said they would adopt it at a high level during Kharif 2021. That seems to mean that farmers adopted DSR at a slightly higher rate in 2020 than in 2021. This is because there was a shortage of workers during the Lockdown in 2020, which made them more likely to adopt DSR than PTR*. In fact, farmers need more people to help with transplanting/PTR, and foreign workers were easy to find before the lockdown. This happened so that the farmer would have to start using the DSR Drill/Machine during the Pandemic Lockdown. So the lack of machines during sowing was the biggest problem, since farms needed them more than ever because foreign workers were hard to find because of lockdowns and other problems. Farmers also had to deal with weed growth, not knowing enough about DSR farming, rain before germination, not wanting to change, etc., which were all very important problems that made it hard for them to use DSR technology. Findings also showed that personality traits, such as education, access to farm equipment, exposure to the media, economic motivation, innovativeness, training on DSR technology, contact with extension, and a willingness to take risks, had a positive and significant relationship with the level of adoption of DSR technology at the 0.05 probability level. So, the overall results show that farmers aren't using the recommended practises for DSR. This means that the government needs to do more to raise farmers' awareness and keep up a strong promotion strategy that includes giving DSR farmers better incentives to increase the number of farmers who use DSR.

Postpartum ovarian activity (Follicular development) by Ultra sonographic studies on postpartum anestrous Sahiwal cows

Paper ID- AMA-27-07-2023-12479

Ultra sonographic studies of ovarian activity in postpartum anestrous Sahiwal Cows. A total no. of 14 anestrus Sahiwal cows with normal parturition of more than 65 days after parturition were procured for present study from Bull Mother Experimental Farm (B.M.E.F.), College of Veterinary Sci. & A.H., Anjora, Durg. These animals were randomly divided into two groups. Animals (n = 7) of control group were given to the normal saline and animals (n=7) of treatment group were given to the injection GnRH @ 10 µgm intramuscularly on day 0. The animals in both groups were monitored at three days’ interval for 24 days i.e. day 0, 3, 6, 9, 12, 15, 18, 21 & 24 days using trans rectal ultrasonography (5-7.5 MHz) for development of ovarian follicles. Significantly higher number of animals came in estrus (57.14% Vs. 28.57% (P < 0.05) in treatment than control group. Significantly (P < 0.05) larger follicles were observed on day 3, 12 and 24 The serum progesterone level was higher on day 0, 11 and 22 in treatment group. However, the difference was statistically non-significant.

Evaluation of Growth Retardant in Hastening the Maturity of Groundnut

Paper ID- AMA-25-07-2023-12477

Groundnut (Arachis hypogaea L.) is a self-pollinated, auto-tetraploid legume crop with 2n=40 chromosomes and belongs to the family Fabaceae. Mepiquat chloride (MC) is an important growth retardant inhibits vegetative growth and accelerates the development of reproductive parts by reducing plant height, thereby decreasing the distance between the source and sink, resulting in better translocation of photosynthetic into developing pods, which is expected to improve groundnut harvest index. Hence the present study, was conducted on SG99 to test the efficacy of growth retardant mepiquat chloride at five concentrations (100,300,500,700 and 900 ppm) keeping check as control. Single foliar spray of mepiquat chloride was given at 40, 60 and 80 DAS. The growth retardant, mepiquat chloride @700ppm significantly reduced days to initiation of flowering, 50%, completion flowering for 4.0 days whereas SPAD value increased by 4.32%. Similarly, Physiological data recorded at 60 and 90 DAS revealed that plant height, root length, root weight was decreased with mepiquat chloride @700 ppm. However, number of branches, nodules number, and nodules weight, dry weight of root, leaves and shoot were more with mepiquat chloride @700 ppm over control. Hence, our results revealed the effective concentration was 700 ppm of the growth retardant.

Influence of Moringa Oleifera Leaf Meal on the Performance of Layer Japanese Quails (Coturnix Coturnix Japonica)

Paper ID- AMA-24-07-2023-12473

The potential influence of Moringa oleifera leaf meal on the performance and cost economics of layer Japanese quails was evaluated in the year 2020-21. A sufficient quantity of crude protein (30.21%) and fiber (8.12%) were found in the M. oleifera leaf meal. Statistical analysis at the end of sixteen weeks experiment revealed that growth characteristics, nutrient utilization, production, and carcass characters exhibited significantly enhanced values in M. oleifera leaf meal-incorporated diets. The liver and kidney function tests exhibited no organ toxicities in the birds following the dietary incorporation of M. oleifera leaf meal. On top of it, M. oleifera leaf meal-incorporated diets showed a reduction in feed cost per kg egg production in the range of Rs. 20.91-56.17. Of various inclusion levels used in the experiment, 2% was found best for all the parameters studied. At last, M. oleifera leaf meal can be recommended in the diet of layer Japanese quails as a safer, eco-friendly, and cost-effective technology.

Genetics of immune-competence traits in a complete 3x3 diallel cross of Indian native chicken breeds with CARI-Red

Paper ID- AMA-24-07-2023-12470

Two Indian native chicken papulation, Aseel Peela (AP), Kadaknath (KN) and one exotic papulation, CARI-Red (CR) maintained at ‘Desi fowl’ unit of ICAR - Central Avian Research Institute were utilized for making full 3x3 diallel cross experiment. General immune-competence of birds (Sample size - 30 birds per genetic group) was evaluated as humoral response as well as cell mediated immunity (CMI) response. The humoral response was studied by estimating the RD-HI antibody titres by Haemagglutination inhibition test [1], while CMI response was estimated as food index [2] against the injection of mitogen (PHA-P). Full diallel analyses were done by using two models model A and model B. Higher values of foot index indicated presence of better cell mediated immunity response to PHA-P and higher values of HI titre indicate better humoral immunity against NDV. The analyses of variance for cell mediated immune response and humoral immune response revealed highly significant difference for GCA at 15 wk of ages in male, female and combined sex in case of model A and B which indicates the additive type of genetic variation. Cross KN x AP had higher and positive Heterosis percentage for cell mediated immune response against PHA-P. In case of humoral immune response against NDV cross CR x AP had highest Heterosis percentage than other crosses.
