Enhanced Flower Pollination Algorithm for Edge Detection and its Application for Segmentation of Banana Leaf Disease Image

Paper ID- AMA-21-02-2022-11155

Edge detection algorithms play a vital role in image processing, computer vision, and machine vision. There is a huge demand for efficient edge detection algorithms for identifying the exact region of interest in an image. The nature-inspired metaheuristic algorithms are more promising than traditional algorithms owing to their stochastic characteristics. The concept of the Flower Pollination Algorithm (FPA) has recently gained much attraction due to solving several complicated optimization problems. In this study, an efficient edge detection algorithm has been developed using FPA for identifying edges in an image. The proposed FPA is capable of identifying the edges with minimal parameterized values, and the parameters are initialized automatically using the concept of maximum entropy and polynomial curve fitting distribution. The performance of flower pollination based edge detection algorithm on ground truth images was compared with other existing methods like Sobel, Canny, Ant Colony based edge detection method, PSO method, and fuzzy-genetic based edge detection methods using Receiver Operating Characteristics (ROC) curve and Area Under Curve (AUC) method. The proposed method performed better compared with other existing methods and had significantly high ROC and AUC indices. Also, the performance of the proposed algorithm was tested on real-time banana leaf disease images and compared with other existing methods in terms of the Shannon entropy index. The segmented images of banana leaf disease through enhanced FPA showed significantly lower mean entropy value, indicating extra-ordinary accuracy and negligible uncertainty of the enhanced FPA. The proposed FPA seems to be promising in developing image processing modules for crop disease diagnosis.

Optimization of Nitrogen Level Under Integrated Weed Management Options for Higher Onion Productivity in Semi-arid Conditions

Paper ID- AMA-20-02-2022-11151

The present study was undertaken to understand the effects of nitrogen (N) on crop–weed interactions for development of integrated weed management (IWM) systems in onion. The field experiment was conducted in semi-arid conditions at SKN Agriculture University, Jobner (India). Seven IWM practices were tested in main plots and four N doses (0, 50, 100, and 150 kg ha-1) in sub plots. The experiment was laid out in split plot design with three replications using onion cultivar RO 252 during two 2016-17 and 2017-18. It was observed that the interactive use of N doses with IWM practices significantly affected crop dry matter (CDM) and marketable yield. Application of two hand weeding (HW) at 20 and 40 DAT combined with 120 kg Nha-1 was most effective to obtain higher marketable bulb yield of onion followed by pendimethalin (1.0 kg a.i. ha-1) + one HW at 40 DAT in combination with 120 kg Nha-1. The study will be useful to effectively control major weed flora and optimization of nitrogen dose for higher productivity of winter season onion crop in loamy sand soils of semi-arid conditions.

Energetics of different cropping systems as affected by resource conservation practices under sub-tropical conditions of Jammu Region

Paper ID- AMA-20-02-2022-11149

A field study was conducted (2012-14) on “energetics of different cropping systems under resource conservation practices” at the research farm, FSR, Centre, Sher-e-Kashmir University of Agricultural Sciences and Technology of Jammu, Main Campus, Chatha, Jammu, India. The experiment was laid out in split-plot design with two crop establishment methods (Minimum/Zero tillage and conventional tillage) and three cropping systems (Rice-Wheat, Rice-Marigold-French bean and Maize + soybean -Wheat) and two fertilizer rates (Rec. Dose of Fertilizer and 75% RDF + 25% N through FYM) with and without mulching in sub-plots under clay loam soil having alkaline in reaction (pH-8.1), medium in soil organic carbon (0.55%) available P (19.20 Kg ha-1 & K(122.0 Kg ha-1) and low in available N (221.12 Kg ha-1) with three replication The maximum input energy (105241 MJ) was recorded under mulched treatment and the maximum EUE was recorded 7.69 % and 7.01 % under maize + soybean - wheat cropping system followed by rice-wheat cropping system (7.49 % and 6.87 %) during first and second year of experimentation, respectively.

Rice threshing and separation process based on detachment force property of rice ears

Paper ID- AMA-20-02-2022-11148

The movement characteristics of rice are important indicators to explore the optimal threshing area and threshing force. This paper presents the motion parameters for threshing straw in the tangential and axial threshing units of the combine. Through the study of the optimal threshing area and threshing force, the reasons for the non-threshing of grains were obtained, which provided the basis for the design of the longitudinal and axial threshing drum. By comparing the threshing force and the detachment force of the grain stem, stem branch and branch axis, the threshing ability of each part of the longitudinal and axial threshing drum was obtained. The results showed that the separation force ranged from 1.48N to 2.29N. The straw performs approximately periodic helical motion in the axial threshing device. The grains on the ears are threshed by the ears of 1-6 rows of longitudinal and axial threshing drums. 2-3 rows of beaters produce stalked grains, and the optimum threshing force is 2.06 N-2.15 N to ensure threshing without stalks and branches. The research is of great significance to explore the optimal threshing zone and threshing parameters.

Dynamics of soil properties and fruit productivity of Kinnow mandarin (Citrus reticulate Blanco) as affected by drip trickle irrigation and hydrogel

Paper ID- AMA-19-02-2022-11147

An experiment was conducted during 2018 - 2020 to assess the impact of drip trickle irrigation intervals viz. 3 and 6 day water supply and different dose of hydrogel viz. 30, 60, 90 and 120 g of soil application with black polyethylene mulch on soil properties, growth, yield and fruit quality attributes in Kinnow mandarin (Citrus reticulate Blanco). The combination treatment of drip trickle ir rigation intervals and hydrogel with mulch recorded the maximum moisture percentage followed by sole hydrogel and drip trickle irrigation intervals. The three days intervals water supply through drip trickle irrigation and 90 g hydrogel with mulch recorded favourable results with regards to soil moisture and physico -chemical characteristics of the soil. Three days drip trickle irrigation and 90 g hydrogel with mulch were found to be most effective in producing maximum vegetative growth than rest of the trea tments. Plant treated with three days drip trickle irrigation and 90 g hydrogel with mulch recorded maximum yield (9290.76 and 9518.72 kg ha -1), followed by three days drip trickle irrigation and 120 g hydrogel with mulch (8973.84 and 9212.92 kg ha-1) while minimum in control plant (5615.60 and 5924.18 kg ha-1) under two year experimentation. Hydrogel retain water and nutrients, when release to the plants surrounding soil near root zone of starts to dry up and black polyethylene mulch is poor aeration and non-decomposable nature. The improving yield due to fact that soil was wet for a longer time in summer season for improving soil moisture levels and fruit quality in subtropical ecosystem.
