Integrated approach for weed management in groundnut

Paper ID- AMA-08-05-2023-12246

Studies conducted at Regional Research Station, Tamil Nadu Agricultural University, Vridhachalam, TamilNadu during rabi/summer 2016-17, 2017-18 and 2018-19 revealed the integration of herbicides with cultural method to contain weeds in groundnut under rice-groundnut system. Among the various herbicides tested, application of Pendimethalin 30% EC @ 1.50 kg a.i/ha followed by (fb) one hand weeding at 25 DAS recorded higher pod yield of 2443 kg/ha over rest of the herbicide combination treatments. The other treatments viz., pendimethalin 30% EC @ 1.5 kg a.i/ha fb Imazethpyr 10% S.L @ 75 g a.i/ha produced pod yield of 2212 kg/ha followed by pendimethalin 30% EC @ 1.50 kg a.i/ha fb quizalopfop ethyl 5 % E.C @ 50 g a.i/ha which gave 2171 kg/ha. All the treatment combinations were found on par with each other and significantly superior over control in terms of pod yield. The weed control efficiency was also higher (91 %) with application of pendimethalin 30% EC @ 1.50 kg a.i/ha fb one hand weeding at 25 DAS. The net return and benefit cost ratio was also higher with the same treatment i.e.application of pendimethalin 30% EC @ 1.50 kg a.i/ha fb one hand weeding at 25 DAS worked out with higher BCR (2.38).

Antioxidant, Anticoagulant, Antithrombotic Activities And Analgesic Effect Of Stem Extracts Of Launaea acanthoclada

Paper ID- AMA-08-05-2023-12244

Launaea acanthoclada is a medicinal plant used to treat inflammations, digestive disorders and wound infections. The aim of our study was to assess antioxidant, anticoagulant, antithrombotic activities and analgesic effects of this plant extracts. The total phenols and flavonoids content of the different extracts were determined using Folin-Ciocalteu and Aluminum chloride colorimetric assays. Antioxidant activity was performed using several methods. The anticoagulant and antithrombotic activity was tested on human blood. To evaluate analgesic activity, the crude extract was subjected to acetic acid-induced writhing test. Crude extract (CrE) and ethyl acetate extract (EAE) showed a potent activity in scavenging DPPH (IC50 of 9.14 ± 1.88 and 44.3 ± 0.85 µg/mL). EAE, CrE, butanol (BuE) and hexane (HeE) fractions displayed the greater activity (> 80%) in inhibition of β-carotene oxidation. However, EAE had an IC50 of 0.87 ± 0.02 mg/mL in hydroxyl radical scavenging assay. Aqueous fraction (AqE) and EAE showed a significant percentage of clot lysis (35.15 and 30.08%). CrE, HeE and EAE inhibit blood clotting even after 3 h. In addition, CrE induced significant antinociceptive activity of 50 and 57.28% at doses of 150 and 300 mg/Kg, respectively. Our findings revealed that L. acanthoclada could be used in the development of new natural medicines.

Combining Ability Analysis of Quality Protein Maize Inbred lines

Paper ID- AMA-06-05-2023-12243

The present study was aimed to assess the general combining ability of parents and specific combining ability of their crosses for yield and quality traits. Nine inbred lines were crossed with three testers using line × tester mating design. Nine lines, three testers and 27 F1s were evaluated along with two checks in this study for grain yield per plant, grain protein content, tryptophan content and lysine content during Rabi 2021-22 and Spring 2022. Total 41 genotypes (27 crosses, 9 lines, 3 testers and 2 checks) were evaluated in Randomized Block Design with three replications at experimental farm of BAC, Sabour. Based on general combining ability analysis parents L4, L6, L9 were found as good general combiner for grain yield & quality traits in rabi season. L1, L2 and L3 were accompanied with significant GCA in desired direction for tryptophan and lysine content in spring season. Among the crosses L2 × T1, L7× T3 and L3× T1, L9 × T3 exhibited highly significant and desirable SCA effects for grain yield per plant in rabi and spring season respectively. L3× T3 possessed highly significant SCA effects for protein, tryptophan and lysine content in spring season. Therefore, these crosses can be utilized for developing high yielding good quality hybrid varieties in maize. There was preponderance of non-additive gene action in the inheritance of all the traits.

In silico Prediction of Antiviral Activity of Andrographis paniculata Against NDV2K35 strain of Newcastle Disease Virus

Paper ID- AMA-05-05-2023-12241

The present study focused on molecular docking analysis of active principles of Andrographis paniculata with NDV2K35 proteins, a strain of Newcastle disease virus. The 3D structures of NDV2K35 proteins (receptors) viz. Haemagglutin-Neuraminidase protein (HN), Fusion protein (F), Matrix protein (M), Phosphoprotein (P), Large polymerase protein (L) and Nucleocapsid protein (N) were downloaded from Uniprot database, modelled using Swiss model analysis and validated by RAMPAGE: Ramachandran plot analysis. The active principles of Andrographis paniculata (ligands) viz. andrographolide, neoandrographolide and 14-deoxyandrographolide were downloaded from PUBCHEM, a database for chemical molecules. The docking analysis was carried out using Accelrys Discovery Studio 4.0 Client software. The results revealed that andrographolide interacted with all except M protein. The dock score of neoandrographolide was more than andrographolide with all the proteins but it failed to interact with F and M protein. The compound 14-deoxyandrographolide interacted with all proteins except F protein but the dock scores were comparatively less. The active principles were further screened for in silico pharmacokinetic and pharmacodynamic properties using Swiss ADME, a standard online tool and PASS online server. The active principles exhibited good GI absorption with bioavailability of 55 % and acted as substrate for p-gp. Of the three, neoandrographolide inhibited CYP3A4 which indicates the possibility for drug interactions. Toxicity analysis showed comparatively higher toxicity for neoandrographolide. Thus, andrographolide can be considered as a better choice for developing antiviral drug against Newcastle disease virus. However, the synergistic effect of all the three may possess better antiviral activity in vivo and needs further study.

Enhancing lentil yield and income of farmers through cluster frontline demonstration in Bundelkhand

Paper ID- AMA-04-05-2023-12239

Studies were conducted in the villages of Chachawali in the Niwari district of the rainfed Bundelkhand region of Madhya Pradesh during 2020–21; Anora in the Lalitpur district, and Semra and Bilati Karke in the Jhansi district of the rainfed Bundelkhand region of Uttar Pradesh from 2021–22. There were 15 front-line demonstrations in Chachawali, Anora, Semra, and Bilati Karke villages of the lentil variety IPL 316: five in Chachawali, five in Anora, two in Semra, and three in Bilati Karke. Each farmer had the opportunity to participate in a demonstration on a one-hectare plot of land. The goal was to improve lentil cultivation technology. Improved technologies included, among other things, high yielding variety, balanced fertilizer use (based on soil tests), and integrated disease and pest management. Chachawali, Anora, Bilati Karke, and Semra villages, in that order, got an average of 1235, 1285, 1408.33, and 1462.5 kg ha-1 from the demonstrations. There was an increase of 27.58, 23.58, 15.84, and 27.37% over the local yield. The average extension gap in Chachawali, Anora, Semra and Bilati Karke village was 2.65, 2.45, 3.13, and 1.92 q/ha, respectively, while the technology gap were 2.45, 2.15, 0.38, and 0.92q/ha, with the technology index being 16.33, 14.33, 2.5, and 6.11 percent in that order. The case study produced an average net return of Rs. 22525.9, 30112.0, 30247.0, and 3565.0 from the villages of Semra, Chachawali, Anora, and Bilati Karke, in that order, while the mean B:C ratio was 1.3, 2.1, 2.0 and 2.2. The data showed that superior varieties, packaging, and processing used in the frontline demonstration programme have contributed to increase in pulse productivity and profitability in the region.
