STUDIES ON EFFECT OF ORGANIC MANURES AND BIOFERTILIZERS ON QUALITY PARAMETERS OF TURMERIC (Curcuma longa L.) VARIETIES
The present investigation on “Studies on the effect of organic manures, biofertilizers on growth, yield and quality of Turmeric (Curcuma longa L.) varieties” was conducted at College of Horticulture, Rajendranagar, SKLTSHU, Mulugu during 2019-20. The experiment was laid out in Factorial Randomized Block Design (FRBD) with 2 replications and 18 treatments. The results revealed that among all the organic manures, biofertilizers, varieties and their combinations, treatment M1 – FYM 45 t/ha + AMC (Arka microbial consortium) 1 lit per quintal manure recorded maximum antioxidant activity (12.01 µg mL-1), Curcumin content (5.75 %) and oleoresin content (9.25 %) followed by M3 – Vermicompost 14 t ha-1 + AMC (Arka microbial consortium) 1 l q-1 compost (12.53 µg mL-1), (5.46 %) and (8.22 %) respectively. Among the varieties, Salem recorded significantly the highest values for antioxidant activity (10.68 µg mL-1), curcumin content (6.03 %) and oleoresin content (10.20 %) followed by followed by V2 – First best treatment of first experiment (Vertical split of mother rhizome) of Rajendra Sonia variety (12.62 µg mL-1), (4.72 %) and (7.48 %) respectively. Among the interaction effects between organic manures, biofertilizers and varieties, the treatment M1V1 – FYM 45 t/ha + AMC (Arka microbial consortium) 1 lit per quintal manure + vertical split of mother rhizome of Salem variety recorded maximum antioxidant activity (10.18 µg mL-1) Curcumin content (7.14 %) and oleoresin content (12.38 %) followed by M3V1 – Vermicompost 14 t ha-1 + AMC (Arka microbial consortium) 1 l q-1 manure + First best variety of first experiment (Vertical split of mother rhizome) of Salem variety (10.51 µg mL-1), (6.41 %) and (10.69 %) respectively.
Response of fodder cowpea (Vigna unguiculata) to domestic sewage water irrigation
Though farmers` feed various vegetative biomass such as fresh, dry or preserved form for feeding livestock, the productivity was found low compared to the world average. As, fodder crops are found as a negligible crop, due importance is not given for cultivation of fodder crops in the field. Along, with this water is also found to be an important factor for not cultivating fodder crops. Fodder cowpea is one of the important fodder crops and fodder cowpea is deprived of resources mostly during cultivation due to its shorter duration and nitrogen fixing ability. As domestic sewage water contains nutrients required for plant growth and development, the experiment was an attempt to understand the response of fodder cowpea to realise its productivity and its effect on soil fertility. A pot experiment with fodder cowpea was laid out in complete randomized block design during rabi season, 2019 and 2020 to assess the effect of different sources of irrigation water on the growth, productivity, nutrient uptake of fodder cowpea and soil fertility after harvest of fodder cowpea. The irrigation treatments consist of application of ground water, domestic sewage water, ground water and domestic sewage water alternatively. Investigation resulted in higher growth, productivity and nutrient uptake of fodder cowpea and improvement in post-harvest soil available nutrients with application of domestic sewage water.
Monitoring of Winter Rice and Acreage Estimation Using Sentinel-1 SAR Data in the Ribhoi District of Meghalaya
Assessing the acreage for crop classification using optical satellite data encounters difficulties in India's rainy season because of continuous cloud cover. Microwave SAR data offers a potential alternative solution, and this research employed an efficient blend of multi-date Sentinel-1 SAR data. During the winter rice season of 2022-23, six sets of SAR data from different dates between June and August were examined in the Ribhoi district of Meghalaya. VH polarization was chosen for classification due to its greater consistency and reliability compared to VV polarization. Supervised machine learning classification algorithms, particularly support vector machine, were implemented for classification using ArcGIS software. The accuracy of this technique was assessed by comparing it with ground truth data, yielding an overall accuracy of 87% with a kappa coefficient of 0.73. Additionally, the estimated winter rice area from SAR images closely matched the reported area (9327 ha) from the State Department of Agriculture under rice cultivation in Ri-bhoi district, confirming result consistency.
Combined hepatocellular cholangiocellular carcinoma in ducks in India
Combined hepatocellular cholangiocellular carcinomas are the rarest form of primary hepatic tumors in avian species. Many reports of cHCC-CCA have been reported in animals with minimum reports in avian family. The present article deals with the occurrence of cHCC-CCA in ducks reported to Veterinary pathology department, LUVAS. Grossly the ducks were emaciated with presence of blood in the abdominal cavity, pale enlarged liver with yellow to green raised firm nodules of varying sizes. Histopathological examination confirmed mixed hepatic tumor as both hepatocellular and cholangiocellular carcinoma lesions were evident. Increased proliferation of the bile duct along with fatty change in hepatocytes with altered cytoplasm-nuclei ratio, anisokaryosis, anisocytosis, binucleation and presence of mitotic figures. Special staining revealed presence of thick fibrous capsule separating the tumor masses. To our knowledge this is the first case of occurrence of combined hepatocellular cholangiocellular carcinoma eluciadted in ducks in India.
Effect of edible coating in Assam Lemon(Citrus limon Burm.) during storage
Assam lemon is one of the important Citrus species. It is indigenous to Assam. Main storage problems of lemon fruits are browning, shrinking of peel, loss of green colour, loss of firmness, and reduced juice content. Providing non-hazardous edible coating would permit the possibility to reach distant markets in fresh form. Use of CMC (Carboxy Methyl Cellulose) as exterior coating along with Sodium Benzoate and Bees Wax coating can increase shelf life of Assam Lemon. The present investigation was carried out in Laboratory, Department of Horticulture, Assam Agricultural University, Jorhat during the year 2022-2023. Treatments includes combination of Carboxy Methyl Cellulose, propylene glycol, sodium benzoate. Fruits were stored in corrugated fibre boxes. Physical and biochemical evaluation was done at every 5 days interval. Different observations were recorded where highest juice content was recorded in T₅ (39.59%), highest TSS recorded in T₅(6.270Brix), highest titratable acidity recorded in T₅(3.42%) and lowest physiological loss in weight was observed in T₃ on 25th day of storage. The results of the experiment revealed that application of treatments had significant effect on various biochemical parameter of lemon fruit during storage. Treatment T₅ (3% CMC + 2% Propylene Glycol + Sodium Benzoate 500 ppm) showed better results followed by T₃ (5% CMC + 2% Propylene Glycol) during storage. T₅ (3% CMC + 2% Propylene Glycol + Sodium Benzoate 500 ppm) was superior as an edible coating and retained better quality with extended storage life as compared to all other treatments.
