Textural quality and nutritional differences of Chinese cabbage (Brassica rapa ssp. pekinensis) under soil fertigation and hydroponics cultivation systems

Paper ID- AMA-02-06-2022-11431

The quality of vegetables is determined by many factors such as texture, flavor, chromaticity, and health-beneficial metabolites. Chinese cabbage is one of the most commonly consumed vegetables in Western and Asian and countries including Korea. Change in firmness of Chinese cabbage leaf tissues has not been comprehensively studied, although it serves as an important quality indicator of this product. The objective of this study was to characterize textural parameters of Chinese cabbage and to compare them in different cultivars and cultivation practices (soil fertigation or hydroponics). Soluble sugar content, leaf thickness, and chromaticity were higher in plants grown via hydroponics than in those grown via fertigation. Meanwhile, firmness and dry mass of midrib tissues showed an opposite trend in all tested cultivars. Additionally, starch contents and cell wall compounds (i.e., polyuronides and non-cellulosic neutral sugars) of midrib tissues were detected higher in plants grown via fertigation than in those grown via hydroponics. Moreover, the amounts of starch, cell wall compounds, and neutral sugars showed a positive correlation with the firmness of Chinese cabbage leaf tissues. Taken together, these data provide an informative insight for improving cultivation practices, particularly hydroponics of Chinese cabbage plants.

Multi-dimensional air flow field of air screen cleaning device

Paper ID- AMA-02-06-2022-11430

Combination mode and working parameters of the cleaning fans of the combine harvester have an important influence on the loss rate and the cleaning rate for different cleaning materials. In this paper, when centrifugal fan was acting alone and cross-flow fan acting alone, the airflow velocity at the indoor space point of cleaning room were measured on a cleaning device. The isokinetic distribution diagrams in different sections were drawn and the characteristics were analyzed. The results showed that under the action of the centrifugal fan, the airflow speed increases as the speed increases. The influence of the cross-flow fan on the screen surface is mainly concentrated on the screen tail, the increase in the speed of the cross-flow fan will expand the scope of influence.

Integrated approaches for management of spot blotch of wheat [Bipolaris sorokiniana (Sacc. In Borok) Shoem] and its effect on crop growth and yield

Paper ID- AMA-02-06-2022-11429

Integration of soil application, seed treatment and foliar spray with fungicide i.e. propiconazole provided protection of spot blotch and increased crop growth and yield of wheat. Among the treatment, the maximum germination with 99.65 % and vigour index with 795.20 was recorded in T3 treatment as seed treatment with bioformulation of T. viride @ 4 % + soil application with vermicompost (1:4) + foliar spray of propiconazole @ 0.1 %). The minimum disease area and disease severity was also recorded in T3 (Seed treatment with bioformulation of T. viride @ 4 % + soil application with vermicompost (1:4) + foliar spray of propiconazole @ 0.1%), representing value as 0.46 cm2 and 10.72 % respectively which was followed by T6 (Seed treatment with bioformulation of T. viride @ 4 % + soil application with mushroom compost (1:4) + foliar spray of propiconazole @ 0.1 %) as 0.52 cm2 and 12.65 %, respectively. The growth promoting effect of wheat crop have also been perceived from integrated approaches. The maximum with 40.15 and 27.40 cm shoot and root length were found in T3 treatment (Seed treatment with bioformulation of T. viride @ 4 % + soil application with vermicompost (1:4) + foliar spray of propiconazole @ 0.1 %). The highest grain yield with 39.01g was also obtained in T3 (Seed treatment with bioformulation of T. viride @ 4 % + soil application with vermicompost (1:4) + foliar spray of propiconazole @ 0.1 %), representing 80.43 per cent increased over control.

Induced Synthesis of defense molecules in Tomato by Inorganic Chemicals against Fusarium wilt

Paper ID- AMA-02-06-2022-11428

Induced resistance using inorganic chemical have ability to reduce the disease incidence of Fusarium wilt in tomato from 78.50 to 9.12 per cent in 2015, 88.50 to 11.00 per cent in 2016 and 90.96 to 9.30 per cent in 2017 at 15 days after inoculation with the minimum calcium chloride treated plants. The tomato plant treated with inorganic chemical as inducers sensitized to produce increased level of soluble protein and total phenol contents with the maximum in calcium chloride treated tomato leaves indicating 34.83, 35.25 and 34.40mg/g in 2015, 35.93, 36.27 and 35.22 mg/gm in 2016 and 35.06, 35.96 and 33.20 mg/g of fresh leaves in 2017 at 5, 10 and 15 days of pathogen inoculation. Similarly, total phenol content was also found maximum in calcium chloride treated plant. Correlation coefficient analysis revealed that there was negative correlation between disease incidence with soluble protein (r = -0.548, -0.564 and-0.519 in 2015, -0.571, -0.570 and -0.517 in 2016 and -0.0.640, -0.643 and -0.635 in 2017) and total phenol (r = -0.576, -0.562 and -0.580 in 2015, -0.528, -0.564 and -0.536 in 2016 and -0.634, -0.521 and -0.536 in 2017) content at 5, 10 and 15 days of treatment.

Image based Multi-Classification and Detection of Plant Leaf Disease using Transfer Learning Approach

Paper ID- AMA-01-06-2022-11427

Agriculture is the backbone for sustainability of any country and plants has a vital role to play in biodiversity sustenance. Crop yield is highly correlated with plant health. Early detection of diseased plant can reduce the adverse effect on healthy plant. Plant leaf is the primary component to identify the abnormality in a plant. Plant leaf images captured by advanced digital cameras can be passed to an advanced computer added system for automated detection of diseased plant at very early stage for fast response. Performing the same process by human being for individual plant is an inefficient and time consuming process which may lead to spreading the disease in whole crop field. Availability of high resolution and GPS enabled digital cameras and advancement in image processing techniques can be utilized to overcome this challenge of early detection of plant disease through plant leaf. The features extracted from image processing tool will be passed a pre-trained deep learning Convolutional Neural Network (CNN) based models for recognizing and classifying the plant disease. Transfer Learning approach is used to increase the efficiency and accuracy of the proposed system. Data augmentation and data balancing techniques are also employed to overcome the overfitting issue. Additionally, the performance of transfer learning approach has been improved in significant manner after adopting efficient pooling and optimization technique. Total 17820 images of different plant leaves (healthy and un-healthy) are used to train and validate pre-trained CNN models. ROC (Receiver Operating Characteristic) curve and other statistical parameters, including specificity, sensitivity, recall, precision and accuracy was applied to compare the performance of various pre-trained model used in transfer learning. The results are clearly indicates that AUC (Area Under Curve) values for implemented models are high and approaching to 0.942. Inclusion of efficient pooling strategy and optimization technique has increased the accuracy by 4-5%. Initially the was ranging from 92% to 95% but after adapting pooling and optimizer the accuracy enhanced to 95%-98%.
