Role of KVK -Jeolikote in adoption of farm technologies in Nainital District of Uttarakhand

Paper ID- AMA-13-10-2023-12659

The study was conducted in Krishi Vigyan Kendra Jeolikote in Nainital district of Uttarakhand to examine the role of KVK in adoption of farm technologies by the farmers. The results indicates that the majority of beneficiary farmers showed high farm technology adoption of 53 per cent for paddy and 30 per cent for wheat, and moderate adoption of 33 per cent for maize, while non-beneficiary farmers showed moderate adoption (43% and 50 %) for paddy and wheat, and low adoption of 54 per cent for maize. In vegetable crops, beneficiary farmers showed very high adoption for brinjal (46 %) and cabbage (40 %), while high adoption for potatoes (43.6%), tomatoes (44.6%), and okra (50%). On the other hand, the majority of non-beneficiaries showed moderate adoption of 60 %, 50 % and 58.6% for potatoes, tomatoes and brinjal, respectively while low adoption for cabbage (50%) and okra (42.4 %).

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.

Prevalence and Identification of Tomato mosaic virus (ToMV) responsible for mosaic disease on Solanum lycopersicum L. in Southern Andhra Pradesh, India.

Paper ID- AMA-11-10-2023-12652

Tomato is an important vegetable crop infected by several viral diseases among them Tomato mosaic disease incited by Tomato mosaic virus (ToMV) is a major constraint for quality tomato production. Tomato growing majorly throughout the year in districts of Anantpur, Kurnool, and Chitoor in Southern Andhra Pradesh. The inoculum is readily available to make the disease a constant threat during all seasons. A survey conducted during the rabi season of 2017-2018 in major tomato growing areas observed that plants were infected with mosaic symptoms. The highest mean percent disease incidence (PDI) of mosaic symptoms on tomato was recorded in the Anantapur district (6.31%) followed by the Chittoor district (5.43%) and lowest in Kurnool district (4.62%). The higher PDI of tomato mosaic disease was reported in Kadiri mandal (6.83%) followed by Kalyanadurgam (6.5%) and lowest PDI at Pileru mandal (3.44%). Similarly, the highest PDI was reported in Hampapuram village (8.41%) followed by Ramiganivaripalle village (8.33%), and the lowest at Kalikiri village (299%). The rod-shaped viral particles were identified from infected samples on TEM assay. The 42.10% (40/95 samples) collected from 30 different major tomato-growing villages, were expressed HR responses on test plants (N. glutinosa). The DAC-ELISA assay with infected samples revealed that the mosaic eliciting agent was Tomato mosaic virus (ToMV) in South Andhra Pradesh.

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.
