DNA bar-coding of plant growth promoting strains of Trichoderma

Paper ID- AMA-13-10-2023-12658

In order to determine the accuracy of species identification of the eight Trichoderma strains, DNA barcode study through intraspecific and interspecific gap analysis was conducted. Comparing the ITS1 region to the Tef1 region, it was found that ITS1 region provided a clear, distinguishable barcode, showing that the ITS1 primer is more effective at differentiating between different species in our comparable set of sequences than Tef1. Also, the eight strains were subjected for genetic diversity study with 12 ISSR primers where high levels of genetic diversity was indicated by high polymorphism and Nei's genetic diversity, with h of 0.46. Plant growth promoting attributes were further tested for eight Trichoderma strains which confirmed three of the strains—Trichoderma harzianum MC2, Trichoderma harzianum NBG, and Trichoderma lentiforme JC1—to exhibit the highest levels of PGPR characteristics. The research demonstrates the genetic diversity of the eight Trichoderma strains and viability of using the strains for production of biofertilizer in sustainable agriculture.

Effect of nanoparticles and sucrose on enhancing the vase life of Rhynchostylis retusa

Paper ID- AMA-12-10-2023-12654

The postharvest life of the flower of endangered orchid species (Rhynchostylis retusa) was examined with different treatments of vase solution consisting of different concentrations of silver and copper nanoparticles (AgNPs and CuNPs), and equal doses of sucrose (6%). The experiment was performed in the Horticulture Laboratory, Assam Agricultural University, Jorhat (Assam) during 2020-2022. During experimentation, it was observed that the treatments with AgNPs and CuNPs substantially improved all the vase life characteristics of foxtail orchid flowers, compared to the untreated control. T3 (AgNPs 20% + 6% sucrose) treatment was found to gain maximum RFW (124.17%) and water uptake (14.67 ml/day). Likewise, maximum retention of carbohydrates (57.92 mg/100ml), TSS (10.86%), and MSI (60.72%) at the end of the experiment were recorded in T3. Furthermore, T3 strongly inhibited the microbial counts (7.12 Log 1₀ CFU ml/L) in the vase solution and extended the average days to flower fading (4.85 days) and vase life (10.85 days) respectively. For all the parameters recorded, treatment T5 (AgNPs 30% + 6% sucrose) remained the second-best treatment among all the treatments followed by T7 (CuNPs 20% + 6% sucrose). Thus, nanoparticles can be successfully used to extend the vase life of foxtail orchid flowers.

Optimization of medium composition for invitro proliferation and rooting of anther derived micro-shoots in African marigold (Tagetes erecta L.)

Paper ID- AMA-10-10-2023-12650

An efficient shoot proliferation response from the anther derived microshoots (1-2 mm) of two heterozygous populations of African marigold (Desi Orange and Desi Yellow) to various invitro media compositions was investigated. The best multiple shoot induction (about 3.34 shoots/explant and 11.57 shoots/explant) after 30 and 60 days of culturing respectively and minimum number of days taken for shoot proliferation (4.05 days) was observed after the microshoot explants were cultured on solid Murashige and Skoog medium (MS) supplemented with NAA (0.1 mgL-1) + meta topolin (0.5 mgL-1). 100 percent shoot proliferation was recorded in the MS medium devoid of any growth regulators and NAA (0.1 mgL-1) + meta topolin (0.5 mgL-1). Length of the shoots was also found maximum (4.14 cm) in the MS medium supplemented with NAA (0.1 mgL-1) + meta topolin (0.5 mgL-1). Between the two genotypes, Desi Orange showed better response in terms of shoot proliferation percentage (61.44%), days for shoot proliferation (8.52 days), average number of shoots per microshoots (2.16 and 6.48 shoots/explant) after 30 and 60 days of culturing and length of the shoots (2.71cm) than Desi Yellow. Maximum rooting (95.89%) and roots/shoot (38.11) were obtained with ½ MS + IBA (0.5 mgL-1). Also, Desi Orange had maximum rooting (91.40%) and roots/shoot (30.84). Meta Topolin and IBA were found superior in increasing the shoot and root growth respectively.

Direct and indirect methods for estimating gully erosion and proposals for management scenarios of the Funa Watershed in Kinshasa, DR Congo

Paper ID- AMA-10-10-2023-12649

The global erosive and sedimentary balances and its three ravines of geomorphological units between two successive levellings including 2019 and 2022, were indeed carried out and presented on the basis of LS MNT and LS Topography. Using the RUSLE model and topographic method, we proceeded to the description of the Funa watershed and the location of the ravines studied. The method of describing ravines involves the description of their geomorphological units, which requires the creation of a typology of forms, processes and factors of erosion and sedimentation within the ravines. Our descriptive method is complemented by a statistical analysis method to group the geomorphological units of the ravines according to the characteristics describing the processes and factors of erosion. Nearly 40% of the watershed surface is exposed to a soil loss rate of more than 25 tonnes per hectare per year, with an average of 45.8 tonnes per hectare per year across all watersheds in the study area. Indeed, the results show that the spatial distribution of soil loss zones classified as "high to critical" obeys specific conditions. According to the analyses, the characteristics of the areas most affected by this problem in the study area are those located on soils of a sandy nature, (Spolicsols). These terrains are usually found on medium slopes at an altitude of between 300 and 400 meters. However, the validity of these results is subject to debate, as these values may vary from one model to another depending on the methods adopted. Two scenarios were developed to determine the impact of these developments, and the results showed that the development of 16% of the watershed surface will reduce average erosion by more than 25%.

Assessing farmers knowledge towards Agri-Nutrition (A2N) in Uttar Pradesh and Telangana: A psychometric test development and impact analysis

Paper ID- AMA-10-10-2023-12648

Food environments improve the health and nutrition benefits of populations. Rapidly changing food systems, production and distribution patterns stress out to leverage the role of agriculture for nutrition. This requires enquiring the knowledge of farmers in both the fields of agriculture and nutrition for appropriate decision-making. The present study attempted to investigate Agri-Nutrition (A2N) knowledge level of 360 farmers from two agro-climatic regions of Uttar Pradesh and Telangana villages with a reliable and valid instrument development based on psychometric principles. The items with difficulty index (20-80), discrimination index (>0.2), point-biserial correlation (>0.2) were selected and administered to final sample. The findings indicate targeted efforts of providing nutrition education in model villages contributed to improved knowledge among farmers, which in turn positively affect nutrition security in the study area.
