Ex post facto and experimental research design was followed to document the most prominent integrated farming system model in the study area, the North Western Zone of Tamil Nadu and based on the documented IFS model an interactive multimedia training module was prepared on integrated farming systems to empower the knowledge level of the respondents in the digital era. Focus group interview and key informants’ technique was used to document most prominent and profitable IFS model in the study area. Among the documented IFS models Agricultrue + Dairy + Goat + Vermicompost was selected as the most suitable model and used for the development of an interactive multimedia training module by collecting the content, relevant pictures, images, videos and then developed the module. The present research work was conducted in all the four districts of North Western Zone of Tamil Nadu; two blocks and two villages each from the selected districts and blocks thus forms 8 blocks and 16 villages were selected for the investigation. Ten farmers from each village forms a total of 160 farmers, 10 Veterianry Assistant Surgeons (VAS) from each district and 10 Subject Matter Specialists (SMS) working in Krishi Vigyan Kendra (KVK) and Veterianry University Training and Research Centre (VUTRC) were selected as respondents of this current study. The developed interactive multimedia module was evaluated to assess its effectiveness in empowering the knowledge and utility through a well structured interview schedule. The collected data was subjected to statistical analysis and interpreted.
APPLICATION OF BIOSTIMULANTS IN BLACK TURMERIC (Curcuma caesia Roxb.)- AN APPROACH TOWARDS MODERN AGRICULTURE
By realising the importance of bio-stimulants, the present experiment was adopted in Black turmeric, consisting of nine treatments replicated thrice under the design of CRBD. The treatments were: T1: Vermicompost @5 t ha-1, T2: Chitosan @ 0.1% + Vermicompost @5 t ha-1, T3: Chitosan @ 0.15% + Vermicompost @5 t ha-1, T4: Chitosan @ 0.2% + Vermicompost @5 t ha-1, T5: Chitosan @ 0.25% + Vermicompost @5 t ha-1, T6: Chitosan @ 0.1% + Humic acid @ 0.2% + Vermicompost @ 5 t ha-1, T7: Chitosan @ 0.15% + Humic acid @ 0.2% + Vermicompost @ 5 t ha-1, T8: Chitosan @ 0.2% + Humic acid @ 0.2% + Vermicompost @5 t ha-1, T9: Chitosan @ 0.25% + Humic acid @ 0.2% + Vermicompost @5 t ha-1. The results showed that growth parameters like plant height (cm), collar girth (cm), leaf width (cm), leaf length (cm), number of leaves plant-1, number of tillers plant-1 and yield parameters like weight of rhizome plant-1 (g), weight of rhizome plot-1, estimated rhizome yield (t ha-1), number of primary rhizomes plant-1, number of mother rhizomes plant-1, dry recovery (%) was recorded highest in T9 (Chitosan @ 0.25% + Humic acid @ 0.2% +Vermicompost @ 5 t ha-1) followed by T8 (Chitosan @ 0.2% + Humic acid @ 0.2% + Vermicompost @ 5 t ha-1). Hence, bio-stimulants like chitosan and humic acid may be used as an ecofriendly input to enhance the production of black turmeric rhizome.
Insights on potential efficacy of aqueous plant extracts in mitigating Anthracnose disease of mango caused by Colletotrichum gloeosporioides
The present study was carried out to evaluate the antifungal efficacy of nine crude plant extract under in vitro conditions against fungal pathogen Colletotrichum gloeosporioides, the cause of anthracnose disease of mango and subsequently potential of efficacy of these bio-resources were also tested in two different geographical conditions of Himachal Pradesh. Aqueous extracts of different plant parts (leaves, fruits, and seeds) were used at concentrations of 10%, 25% and 50% (w/v), which amended with potato dextrose agar culture medium on which discs of C. gloeosporioides were inoculated using Poison food technique followed by incubation at room temperature for seven days. Therefore, the result of finding demonstrated that among all nine aqueous plant extracts, Azadirachta indica (Neem) exhibited 74.2 per cent as significantly highest mycelial growth inhibition which was followed by aqueous fruit extract of Emblica officinalis (Aonla) with mycelial growth inhibition of 62.4 per cent, respectively. However, aqueous leaf extracts of Murraya koenigii (Karipatta) was reported to be significantly least effective (40.4%) in inhibiting the mycelial growth of Colletotrichum gloeosporioides. This suggests that aqueous leaf extracts of neem attributed fungicidal properties against target pathogen, C. gloeosporioides. Additionally, potential antifungal efficacy of in vitro tested four most effective botanical comprised of Emblica officinalis, Azadirachta indica, Aloe barbendens and Melia azedarach were evaluated in two different geographical conditions of Himachal Pradesh viz. DhaulaKuan and Jachh. Under field conditions, among all treatments foliar sprays aqueous leaf extracts of A. indica (15%) exhibited significantly highest per cent disease control both on leaves (53.2%) and fruits (50.2%), respectively. From the present study, we can conclude that the aqueous leaf extract neem can be explored as effective eco-friendly alternative over hazardous synthetic fungicides to mitigate anthracnose disease incidence even at field conditions.
Effect of pruning on yield and quality of guava cv. Shweta planted in high density orchard under sub-tropical conditions of North Indian.
Guava (Psidum guajava L) is one of the most promising fruit crops of India and is considered to be one of the exquisite nutritionally valuable and remunerative crops. Its cultivation is done on the commercial scale due to three fruiting seasons viz., Ambebahar, Mrigbahar and Hasthbahar. Continuous bearing results in reduction of yield with small size fruits. The heaviest flowering was observed in rainy season guava crop, but the fruits of this season are rough, insipid in taste, poor in quality, less nutritive and are heavily attacked by many insects, pests, and diseases. In order to overcome this problem and to force a full crop during winter season, pruning should be done during February alongwith spraying of NAA 500ppm. Therefore, these studies were conducted to increase the winter season crop of guava conducted at Advanced Centre for Horticulture Research, SKUAST-J, Udheywalla, Jammu during the year of 2023-2024. The pruning was done at different levels and the results revealed that the maximum optimum optimum plant height (2.95 m), Plant spread (E-W) (2.98 m), plant spread (N-S) (2.96 m), plant volume (5.85 m3), girth of primary branches (2.17 cm), number of leaves per shoot (48.43) and number of leaves per tertiary shoots (15.69), were recorded in treatment – 4 comprising of 50 percent pruning of guava trees similarly, maximum leaf area (62.23), petiole length (0.66 cm), leaf chlorophyll content (53.80 SPAD), tertiary shoot girth (1.61 cm), number of flowers for per plant (243.31), fruit set% (74.10%), fruit length (6.22 cm), fruit width (5.03 cm), fruit weight (162.26 gm), fruit volume (166.06 cc), number of fruits per plant (129.88) and highest yield (21.08 kg/plant), total soluble solid (14.15° Brix), ascorbic acid (229.99 mg/100gm per pulp), pulp percentage (97.71%), pH of juice (5.08), total sugars (9.55%), reducing sugars (5.42%), non-reducing sugars (4.13%), pectin (1.86%), available nitrogen (242.76 kg ha-1), available phosphorus (17.23 kg ha-1) and available potassium (1424.27 kg ha-1) was also found best with 50% pruning intensity in guava trees during February –March under north Indian conditions of India. In general, the 50% pruning intensity was found best for enhancing vegetative growth and fruit quality of winter season guava under Jammu sub-tropics.
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.
