Influence of herbicidal weed control strategies on weed dynamics, wce, wi, productivity and nutrient acquisition by indian mustard [brassica juncea (l.) Czern & cosson] in the eastern region of uttar pradesh

Paper ID- AMA-24-09-2023-12611

To investigate the effects of weed management practices on the dynamics of the weeds, the WCE, the WI, and the performance of Indian mustard [Brassica juncea (L.) Czern & Cosson] during the Rabi season 2017-18, an experiment was conducted at the Narendra Deva University of Agriculture and Technology's Agronomy Research Farm in Kumarganj, Ayodhya. The experiment comprised of nine treatments, viz., T1-weedy check; T2-one hand weeding at 30 DAS; T3-two hand weeding at 20 and 40 DAS; T4-Pendimethalin (PE) 1.00 ai kg ha-1 ; T5-Oxyflorafen (PE) 1.00 ai kg ha-1; T6-Isoproturan (PE) 1.00 ai kg ha-1; T7-Pendimethalin (PE) 1.00 ai kg ha-1 + One-handed weeding at 30 DAS; T8-Oxyflorafen (PE) 1.00 ai kg ha-1+ One-handed weeding at 30 DAS and T9-Isoproturan (PE) 1.00 ai kg ha-1+ One-handed weeding at 30 DAS was evaluated in a Randomized Block Design with three replications. In the results of this study, we found that the crop was infested with five different kinds of weed flora. Among these were Phalaris minor and Cynodon dactylon which were the dominant grass weeds. In total, 26.7% of the total weed flora of the region was composed of broadleaved weeds (C. album and Anagallis arvensis). In the total weed flora of the park, the sedge (Cyperus rotandus) constituted 26.7% of the total weed flora, followed by other weeds. A variety of weed management practices were tested. Under treatment involving two-hand weeding at 20 and 40 DAS, weed index (WI), weed intensity reduction, dry matter reduction, and nitrogen uptake were found to be the best weed control efficiency, weed index (WI), and weed reduction. Pendimethalin (PE) was applied at 1.00 kg/ha plus one hand weeding was done at 30 DAS. It is therefore possible to conclude that weeding with both hands at 20 and 40 days of acorn cultivation and fallowing with pendimethalin (PE) @ 1.00 kg/ha together with one-handed weeding at 30 days of acorn cultivation may be a better approach to reduce weed density in mustard crops and to improve their productivity.

Exploring Vermicomposting Potential: A Comparative Study of Exotic and Indigenous Species for Sustainable Waste Management

Paper ID- AMA-23-09-2023-12610

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’

Paper ID- AMA-22-09-2023-12609

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

Paper ID- AMA-22-09-2023-12608

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

Paper ID- AMA-20-09-2023-12606

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.
