Exploring Vermicomposting Potential: A Comparative Study of Exotic and Indigenous Species for Sustainable Waste Management
Vermicomposting, an eco-friendly waste management approach utilizing earthworms to transform organic waste into nutrient-rich compost, offers distinct advantages over conventional composting methodologies. Nevertheless, the comprehensive evaluation of diverse earthworm species, particularly exotic and indigenous variants, in vermicomposting processes remains relatively limited within the existing literature. In this study, we aimed to bridge this knowledge gap by scrutinizing the decomposition kinetics, nutrient profiles, and overall compost quality of two exotic species (Eudrilus eugeniae and Eisenia fetida) alongside one indigenous species (Drawida nepalensis). Our findings reveal discernible variations among the earthworm species in terms of maturation durations, bulk density, pH levels, total organic carbon, total nitrogen, total phosphorus, total potassium, total calcium, total magnesium, dehydrogenase activity, and urease activity. Remarkably, Eisenia fetida exhibited superior performance relative to the other species by significantly reducing total organic carbon content, augmenting nutrient concentrations, and enhancing enzymatic activity. These outcomes underscore the substantial influence of earthworm species selection on the resultant quality and composition of vermicompost. The insights derived from this research have significant implications for advancing environmentally sound waste management practices and enhancing our understanding of the role played by diverse earthworm species in the vermicomposting process.
Optimization of in-vitro protocol for rapid mass multiplication of floribunda rose cv. ‘Rose Sherbet’
An in-vitro protocol was developed for rapid mass multiplication of rose cv. ‘Rose Sherbet’ under in-vitro condition using axillary buds as explants segment. Out of different pre-treatments for explants, the highest explant survival (76.41 %) and less microbial contamination (13.5) was obtained with treatment (T1) 0.2% Carbendazim + 200 mg/L 8-HQC for 3 hours. Ex plant surface sterilized with 0.1 % HgCl2 for 5 minutes exhibited the maximum survival percentage (74.46%). MS medium supplemented with 5.0 mg/L BAP + 0.1 mg/L NAA + 0.5 mg/L GA3 was found most effective for culture establishment, however, MS medium comprising 4.0 mg/L BAP + 0.1mg/L NAA+ 0.2 mg/L kinetin along with 40 mg/L adenine sulphate was found to be better for shoot proliferation with highest number of micro shoots (4.96 shoots/explant). Elongation of plantlets and maximum internode length was recorded in MS + GA3 2.0 mg/L while rooting of micro shoots was induced on MS basal medium supplemented with IBA (0.5 mg/L). The regenerated plantlets were efficiently hardened in plastic pots (4”) filled with coco peat + vermiculite + perlite (1:1:1) which is further moistened with half strength MS medium salts and covered with polythene. Survival percentage, plant height, number of branches and number of leaves/plants were found maximum in this treatment. Thereafter, plants were successfully transferred to the glasshouse with good survival.
Unveiling the Biochemical Metamorphosis of Tea Before and After Helopeltis theivora Infestation
Helopeltis theivora, a severe pest, damages young tea plant buds, reducing black tea quality. We studied Tocklai vegetative clones TV1 and TV23 at four infestation levels (none, low, moderate, high). Results showed significant differences in various biochemical qualities. Moisture dropped from 3.04% to 2.13%, dry matter increased from 96.96% to 97.86%, caffeine decreased from 3.71% to 2.50%, DPPH antioxidant activity declined from 70.44% to 51.26%, TSS decreased from 44.60% to 36.78%, and total polyphenol content decreased from 22.38% to 14.99%. TV1 had the highest TF:TR ratio (1:10.89) in non-infested samples, while TV23 had the lowest (1:7.63) in heavily infested samples. Brightness (%) ranged from 33.07% to 46.07%, and color index from 4.2% to 5.32%. Organoleptic qualities (brightness, briskness, strength, quality) decreased with increasing infestation, highlighting the negative impact of Helopeltis theivora on tea quality.
Mulching improves strawberry fruit yield and quality by regulating soil temperature and anti-oxidant enzyme activities in humid tropical India
Little information exists on the effect of mulching and its mechanisms regulating environmental factors, as well as biochemical constituents to improve yield and quality of strawberry (Fragaria × ananassa, Duch.)in humid tropical India. The effects of different coloured plastic mulches (black, transparent, and red) and organic mulches (paddy straw, banana leaves and weeds) were tested on the yield and quality of strawberries. The mean fruit yield with black plastic mulching was 68% greater than the control. Total sugar, reducing sugar, and total soluble solids were 19, 16, and 17% higher in black polythene mulching, whereas, ascorbic acids and organic acids were significantly lower under plastic mulching than in control. Activities of catalase, phenoloxidase and perosxidase were lower under plastic mulching than in control. Black polythene adjusted environmental factors and physiological processes to boost productivity and quality of strawberry fruits.
ANALYSIS OF THE SOCIO-ECONOMIC AND PSYCHOLOGICAL PROFILE OF RURAL YOUTH OF BARGARH DISTRICT OF ODISHA
In the academic year 2018–19, the study was carried out in the Bargarh district of the state of Odisha. 120 respondents in total were chosen for the investigation's purposes. The socioeconomic and psychological profiles of the respondents were analysed using descriptive statistics (mean, frequency distribution), and they were ranked as a result. In terms of socioeconomic profile, data collected on education showed that the majority (40%) of respondents had only completed high school, the majority (71.66%) were married, the majority (65.00%) had no membership in any organisations, and the majority (100.00%) of respondents received information about agri-related activities from friends, neighbours, relatives, and farmer friends. The majority (60.00%) had no membership in any organisations. According to the respondents' psychological profiles, the majority of respondents (mean score=1.93) preferred to increase their income through crop production, the majority of respondents (mean score=1.82) had psychology to choose agriculture farming as a career, and the majority of respondents (mean score=1.77) preferred agriculture labours. The socioeconomic profile of a person's education, scientific attitude, and preference for agricultural work among rural adolescents are all highly relevant factors. The youth's adoption of cutting-edge technology will be facilitated by need-based, problem-oriented, and location-specific technologies. Young people in rural areas need to be given the skills necessary to use cutting-edge technologies, which will increase their income and standard of living.
