Comparison of Innovation Ability, Patents, Agricultural Machinery Enterprises in Jiangsu Province of China
Jiangsu is a large agricultural province and grain-producing province in China. Agricultural machinery enterprises in Jiangsu are the main body of scientific and technological innovation of agricultural mechanization in the province. There is a close intrinsic connection between technological innovation and patent. This paper takes patents as a perspective to conduct a comparative study on the innovation ability of agricultural machinery enterprises in Jiangsu. The study shows that the patents of Jiangsu agricultural machinery enterprises are mainly utility model, of which the proportion of utility model patents is 79.93%. The vast majority of enterprises rely on their own technical force to carry out product and technology innovation, and about 1/4 of them have applied for patent cooperation with universities and institutes. There are 88.6% of enterprises did not apply for international patents. The difference in innovation power of enterprises in the first, second, third and fourth echelons is obvious.
Role of KVK -Jeolikote in adoption of farm technologies in Nainital District of Uttarakhand
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
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
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.
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.
