Performance of Kisan Drone through Large Scale Demonstrations in Paddy fields of Southern Telangana Zone
The present study was carried out through Large Scale Demonstrations (250 no.s) of Kisan Drone in an area of 625 acres and implemented successively in the operational area of ICAR- KrishiVigyan Kendra, Kampasagar, Nalgnoda district (Telangana state) under Agricultural Drone Project, financed by ICAR, ATARI during the year 2022-23 to appraise the effect of Drone utilization for spraying of Agricultural chemicals. In this study, Conducted 250 demonstrations on spraying of insecticides, fungicides, post emergence weedicides, and Nutrients in 625 acres, majority of the demonstrations were carried out on Pest management in 530acres (212 demonstrations) other weed management and Nutrient management sprays were covered in 95 acres (38 demonstrations) in paddy crop. In Farmers practice, spraying was done with manual operated power sprayers. From this study, it was concluded that, there is a vast scope for drones in agricultural applications. Drones will be able to spray more land in less time. This will save the time of farmers i.e., 16 minutes/acre in demonstration field, as compared to 84 minutes/acre in farmers’ practice. The cost of spraying was reduced to an extent of Rs 150/acre as compared farmers’ practice, hence resulting in financial savings of the farmers. There was 13 per cent yield increase in demonstrated plot over farmers plot because of timely sprayings. About 72% of the pest population was reduced in demonstration field and farmers were satisfied with this technology. There is a need to further disseminate the improved technologies among the farmers with effective extension methods like training and demonstrations. Farmers’- should be encouraged to adopt the technology for realizing higher returns. Horizontal spread of improved technologies may be achieved by successful implementation of demonstrations and various extensions activities like Training Programmes, Awareness Programmes, field days etc. organized in the farmers’ fields. Farmers have shown keen interest to adopt this technology in large area in the ensuing seasons.
Nutritional status and Feeding Practices assessment of Middle Gangetic Plain lactating cattle in organized and unorganized farm
Feeding practices and nutritional status data of lactating cattle were collected from livestock farm complex, ANDUA&T, Kumarganj Ayodhya and unorganized farms of Middle Gangetic Plains of Uttar Pradesh, India. A total of 100 cattle were selected as per stratified randomized design (SRD) from organized and unorganized farm. Nutritional status of lactating cattle was ascertained through body weight, milk yield and feed intake data as well as from serum metabolic profile values. Cattle of organized farm were heavier (P<0.05) than unorganized farm. The milk yield of cattle were significantly (P<0.05) higher in organized farm than unorganized farm. In organized farm cattle were mainly maintained on wheat straw, berseem, sorghum and concentrate while in unorganized farm they were maintained on wheat straw and available green fodder and/or local grasses along with very low amount of homemade concentrates. Lactating cattle of unorganized farms were deficient in DM intake and the deficiency of CP and TDN was significantly (P<0.05) higher in organized farm than unorganized farm. Among blood biochemical parameters, the serum glucose, total protein, albumin and globulin were found within the normal range and did not vary significantly (P>0.05) between farm. Thus, it is concluded that the dairy animals in Middle Gangetic Plain were fed with traditional manner and they were deficient in DM, CP and TDN supply.
Studies on the Effect of Organic source of nutrients on growth, yield and quality of Potato
A field experiment was conducted at research farm, Bhola Paswan Shastri Agricultural College, Purnea, BAU, Sabour to evaluate the effect of organic source of nutrients on growth, yield and quality of Potato. The treatments comprises of seven treatments which includes T1(RDF (150:90:120 kg NPK/ha),T2 (100% RDN through FYM),T3(75% RDN through FYM + 25% RDN through Vermicompost), T4(75% RDN through FYM + 25% RDN through Poultry manure),T5(50% RDN through FYM + 50% RDN through Vermicompost),T6(50% RDN through FYM + 50% RDN through Poultry manure), T7(50% RDN through FYM + 25% RDN through Vermicompost +25% RDN through Poultry manure). Among the different treatments T1(RDF (150:90:120 kg NPK/ha) recorded the highest growth and yield parameters as compared with other treatments but the results were at par with T7 (50% RDN through FYM + 25% RDN through Vermicompost +25% RDN through Poultry manure). In case of quality and soil parameters the results showed that organic treatments recorded significantly higher value as compared to T1 (Control).
In- vitro efficacy of essential oils, Lemongrass and Khus oil against E.coli and Klebsiella spp. isolated from Buffaloes Suffering from Subclinical Mastitis and its use as a post milking teat spray.
Lemongrass (Cymbopogon) and Khus (Vetiver) oil, an essential oils play an important role in antibacterial and anti-inflammatory properties. Present study was designed for the in-vitro efficacy of essential oils, Lemongrass and Khus oil, against common mastitis causing organisms namely Klebsiella spp. and E.coli. Total 220 animals were screened using California mastitis test and white side test in the study area. Out of 200 animals total 124 animal were found positive for sub clinical mastitis. Of these samples, around 30 samples were subjected to further bacterial isolation, wherein, E.coli and Klebsiella spp. were isolated. The best combination of oils was further tested as a spray in lactating buffaloes suffering from SCM. 100% of E.coli isolates were sensitive to Ceftriaxone, Enrofloxacin, Ceftriaxone and Sulbactam combination followed by Streptomycin and Gentamicin (90%), Vancomycin and Tetracycline (60%), Oxytetracycline (40%) and Penicillin (20%). The order of sensitivity observed against Klebsiella spp. was Enrofloxacin and Gentamicin (100%), Streptomycin, Ceftriaxone & Sulbactam (90%), Ceftriaxone (70%), Oxytetracycline, Amoxycillin (50%), Penicillin, Vancomycin and Tetracycline (40%). Enrofloxacin had the maximum activity against S. aureus and Klebsiella spp., whereas, ceftriaxone has maximum efficacy against E.coli. Overall, maximum zone of inhibition was achieved by 75% Lemongrass Oil + 25% Khus Oil combination across the two bacterial isolates categories. Further, the efficacy of essential oil of Cymbopogon citratus and Vetiveria zizanoides as a teat spray (75% lemongrass oil + 25% khus oil) combination in prevention of mastitis was studied. This was tested in healthy buffaloes as well as SCM affected buffaloes. The animals were divided in 4 groups for the study of the efficacy of essential oil combination as a teat spray with 10 animals in each group. Post 15 days of therapy, Group 1 (healthy buffaloes) had minor changes in evaluated parameters. Group 2 (healthy buffaloes) showed improved results where the healthy buffaloes were sprayed with essential oil spray. Group 3 (SCM buffaloes) where no treatment was given, an increase in SCC was observed. The final group 4 animals (SCM buffaloes+ spray) showed 70% recovery with a decline in CMT scores, WST scores as well as SCC scores.
TOXICITY ASSESSMENT OF SELECTED INSECTICIDES AGAINST ADULT Spodoptera frugiperda (FALL ARMYWORM) UNDER LABORATORY CONDITIONS
This study evaluates the toxicity of selected insecticides on adult Spodoptera frugiperda and their effects on oviposition and egg hatchability. The findings contribute to improved pest management strategies targeting adult FAW. A laboratory bioassay was conducted at the University of Agricultural Sciences, Dharwad, during 2022–2023. Adult FAW were exposed to insecticide-treated surfaces for 30 seconds, and mortality was recorded at 24, 48, and 72 hours. Oviposition and egg hatchability were assessed in females paired with treated males. No significant adult mortality was observed within 72 hours post-treatment. However, insecticides significantly reduced oviposition and hatchability. Chlorantraniliprole 9.3% + lambda-cyhalothrin 4.6% ZC caused the highest reduction in egg production (165.60 eggs/female) and hatchability (53.65%). Novaluron 5.25% + emamectin benzoate 0.9% w/w was the second most effective, reducing egg production (176.87 eggs/female) and hatchability (61.90%). The study demonstrates that insecticide-treated male S. frugiperda can influence female reproductive success by reducing oviposition and egg hatchability. This suggests that targeting adult moths with specific insecticides can be an effective strategy for suppressing FAW populations. Incorporating such approaches into integrated pest management programs could enhance control measures and minimize crop damage.
