Comparative assessment of poultry dropping and dairy waste on physico-chemical parameters of water
The present experiment was designed to investigate the effect of poultry dropping and dairy waste on physico-chemical parameters including water temperature, pH, dissolved oxygen (DO), and alkalinity. Water samples from three treatment ponds-poultry dropping-treated, dairy waste-treated, and control (no manure) were analysed for a period of seven months. The maximum water temperature of 30.03±1.890C was recorded in poultry dropping treated pond, whereas pH 7.78±.104 and alkalinity 89.85±5.50 was maximum in dairy waste treated pond while control (no manure) pond with 6.44±.84 has maximum level of dissolved oxygen. The analysis of data revealed that while appropriate levels of waste input enhanced nutrient availability for fish production, excessive application led to significant deterioration of water quality, characterized by decreased Dissolved Oxygen, elevated nutrient concentrations. The study underscores the need for optimized application of organic manure to sustain aquaculture while minimizing environmental risks.
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.
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.
