Evaluation and Molecular Characterization of Native Fluorescent Pseudomonads against Fungal and Bacterial Wilt of Brinjal

Paper ID- AMA-13-09-2022-11673

Brinjal (Solanum melongena L) is one of the most common vegetable crops grown in tropical & subtropical regions of the world. Brinjal cultivation is affected by various pest and diseases. The soil borne diseases like fungal and bacterial wilt are the most destructive diseases of brinjal. These are caused by Fusarium oxysporum f.sp. melongenaeSchlecht (Fungal wilt)Ralstonia solanacearum (Smith) Yabuuchi et al. (Bacterial wilt). Under the present investigation two isolates of FluorescentPseudomonads (FLPs) viz., FLP-Brinjal 2020-1 and FLP-Brinjal 2020-2, were evaluated against two major pathogens of brinjal viz., Fusarium oxysporum f.sp. melongenae (FOM) andRalstonia solanacearum(RAL)under in vivo and in vitro conditions using dual culture and inverted plate assay. FLP-Brinjal 2020-2 gave maximum inhibition over the control followed by FLP-Brinjal 2020-1 against both the pathogens. Experiments conducted in pluck trays indicated that FLP-Brinjal 2020-2 was superior with maximum germination percentage (63.75%), vigour index (650), disease control percentage (58.66%), bio-control efficiency, plant growth (10.20 cm) and minimum disease incidence (20.62%) against bacterial wilt pathogen. Similarly, under brinjal fungal wilt experiment maximum bio-control efficiency, plant growth (11.20 cm) and minimum disease incidence (%) (24.81%) among the Fusarium challenged treatment was found with FLP-Brinjal 2020-2. The identity and diversity among the FLP isolates were examined by sequence analysis of 16s rRNA gene. The gene was amplified by PCR using primers pair, 27 F/1492 R. Amplified DNA products were sequenced, and analysed by BLAST programme at NCBI database for species identification. Among the 10 FLP isolates assessed, 9 were found to have maximum similarity with Pseudomonas aeruginosa includingFLP 2020-2 and FLP 2020-1 was found to be Pseudomonas fluorescence which is in confirmation with the morphological observations.

Direct seeded rice (DSR) is a feasible alternative to conventional puddled transplanted rice with good potential to save water, reduce labour requirement, mitigate green-house gas (GHG) emission and adapt to climatic risks. Paddy is major predominant crop during Kharif in erstwhile Nalgonda district of Telangana, cultivated in an area of 3,95,090 ha, out of total cropped area of 6,87,966ha with productivity of 2664 kg/ha. Production of conventional puddled transplanted rice is facing severe constraints because of water and labour scarcity and climatic changes. The yields are comparable with transplanted rice if crop is properly managed. In 2019 to 2021, efforts have been made in promoting the DSR technology in Nalgonda with collaboration with Reddy’s foundation under Corporate Social responsibility by Krishi Vigyan Kendra, Kampasagar of PJTSAU university. Direct sowing of Rice with Seed cum Ferti Drill is boon to farmers to save money, time, water and crop comes to harvest 7-10 days earlier than normal transplanted paddy. KVK, Kampasagar, Nalgonda extension centre has organized Frontline Demonstrations (FLDs) in farmer fields in two seasons Kharif, 2020 and Kharif, 2021. Direct sowing of Rice with Ferti Cum Seed Drill recorded 12.90 % more grain yield over normal transplanting method of paddy cultivation during both Kharif seasons. The results from the present study showed that farmers realized 53.0% increase in net income due to increased grain yield by 12.90% with reduction of cost of cultivation by 31.80%, it could be attributed to reduction in manual labour of 6man labour and 30 women labour and also increase in yield attributes and yield.

Estimation of Gene effects through Generation Mean Analysis and Validation of known markers associated with Zn content in rice through Bulked Segregant Analysis

Paper ID- AMA-13-09-2022-11671

Generation mean analysis investigation in rice was carried out to assess the gene action operating in the inheritance of yield, its components, and quality traits. Five basic generations viz., P1, P2, F1, F2, and F3 of three crosses, namely IET-25475 x IET-25477(Cross-I), GNR-7 x GNR-3 (Cross-II), and GAR-13 x IET-25477 (Cross-III) were studied. A scaling test was applied to test the adequacy of the additive-dominance model for the traits under investigation. The result of individual scaling tests C and D revealed that the additive-dominance model was found inadequate for the description of variation in generation mean for all the eleven traits of all three crosses. Based on five parameter model, the main effects viz., mean (m), additive (d), and dominance (h) and two digenic interactions, additive x additive (i) and dominance x dominance (l) were significant for days to flowering in cross-I; for productive tillers per plant in cross-I and cross-III; for grains per panicle and 100-grain weight in cross-II; for grain yield per plant in cross-II and cross-III; for straw yield per plant and amylose content in cross-I and cross-II and days to maturity, plant height, L: B ratio and Zn content in all crosses indicated that involvement of additive, dominance as well as epistasis interaction for controlling this trait. BSA was carried out to identify markers linked to Zn content using 235 plants from F2 segregating generation of GAR-13/IET-25477, two indica ecotypes with extreme Zn content. The parents were screened for polymorphism using fifty rice microsatellite primer pairs. Out of 50 SSR primers, only two were found able to discriminate both the parents (HIGH Zn content and low Zn content) sufficiently. Two markers (RM 21 and RM 248) were identified as linked to the Zn content gene through BSA.

Biological Activity of Some Plant Extracts Against Callosobruchus maculatus (F.(

Paper ID- AMA-11-09-2022-11669

Acacia farnesiana, Platychladus [Thuja] orientalis Endl, Swietenia mahogoni (Linn) Jaq and Pancratium maritimum are four plants growing in Egypt. Hexane and ethanol had been used to extract oils from tested plants. Leaves and seeds were used from A. farnesiana, and P. [Thuja] orientalis Endl and leaves from S. mahogoni (Linn) Jaq while bulbs were used from Pancratium maritimum. All extracted oils were evaluated on Callosobruchus maculatus (F.) biology. Plant oil extracted from Cassia seeds with ethanol had the strongest effect and decreased hatching to 0.5% with concentration of 5 grams crude extract/kilo gram seed and also had the strongest reduction with 100% reduction with the same concentration. All tested extracted oils had an effect against F1 progeny and after storage cassia leaves had the weakest effect and the extract had no effect on biology after two months of treatment. All tested extracted had a negative effect on seed germination and Arbor-vitae leaves had the most negative effect on cowpeas seeds with 75% germination.

Agricultural Sector: Status, Challenges and its Role in Indian Economy

Paper ID- AMA-10-09-2022-11668

In this study, we use a simple regression analysis to explore the relationship between agricultural inputs and agricultural GDP in the Indian economy from 1980–1981 to 2011-2021. The agricultural gross domestic product serves as the dependent variable, while fertilizers, net irrigated area, pesticides, electricity, rainfall, and the use of high yield varieties of seeds serve as the independent factors. Statistical analysis shows that factors influencing agricultural GDP from 1980–1981 to 2011-2021, such as fertilizers and net irrigated area, have little to no effect. Further, the study finds that variables including pesticides, electricity, rainfall, and seeds are statistically significant, leading researchers to conclude that they all had a major impact on agricultural GDP within the time frame under consideration. The authors argue that the government can influence the agricultural sector in two ways: by regulating inputs and by influencing outputs. The report emphasizes the need of revitalizing public sector investment because of its multiplier effect on the sector's total GCF. As a result, it is important to develop a long-term perspective strategy for rural infrastructure that prioritizes the most effective infrastructure projects.
