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.
Assessment of technology intervention for preparation of paneer and characterization employing Principal Component analysis (PCA)
Traditional Indian Dairy Products hold a promising position in cultural and dietary values. In this context, paneer is one of the widely accepted heat and acid coagulated product, occupying a special place in Indian market. Although the preparation methodology is quite simple and is prepared at every household level, a drastic variation could be observed in the product, attributed to technological factors. The critical role of milk quality, temperature, acidulants, and moisture is interrelated and affects overall sensory and proximate composition of the product. Therefore, keeping in mind the importance of all variables, and to bolster the rural women empowerment, trainings were provided under the project mandate identified in Farmers First Project. The sensory quality of the product identified 15 different variables, with four principal components able to explain 87.132 percent of the total variation, which improved further after removing non-redundant terms from the list.
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.
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.
