Development of Battery Operated Row Crop Weeder for Small Farm Mechanization
The manual method of weed control is effective, but the scarcity of labour during the peak season and delay in weeding operations ultimately reduces crop yield. The use of chemical herbicides over a period of time leads to environmental pollution. Mechanical weeding is preferred over chemical use because herbicides are expensive and hazardous to the environment. Therefore, the development of mechanical weeder is imperative to meet the demand of small-farm mechanization. The available engine-operated mechanical weeder increase drudgery to the operator due to exposure to high levels of vibration. Hence, the complexity of these situations has resulted in switching over to an electric- drive mechanical weeding system to increase the productivity of the man-machine system. Therefore, a battery-operated inter-row weeder has been developed. It has an electro-mechanical approach such as the application of a DC motor as a power source and a combination of weeding mechanisms to complete the operation with less drudgery and higher efficiency. The field experiments were conducted in soybean crops under sandy-loam soil conditions. The field performance of weeder for V- type blade and straight blade tool were evaluated at the forward speed of 2-3 km/h. The results showed that the average weeding efficiency, field capacity, field efficiency, percentage plant damage, and performance index of the machine for V-type blade were found to be 91.42%, %, 0.051 ha/h, 90.73%, 2.37% and 2496.30, whereas for straight blade 86.78%, 0.048 ha/h, 88.50%, 3.55%, and 1497.04 respectively. The average power consumption of the weeder for V-type blade and the straight blade was found 185.6 and 262.5 W. The average draft force 269 and 391 N was observed for V-type and straight blades. The performance of the V-blade was found better over the straight blade. The developed weeder was found suitable for small-farm mechanization.
The Use of Organic Fertilizers and Arbuscular Mycorrhizal Fungi to Increase the Growth of Banana Raja Bulu Seedlings (Musa paradisiaca L. cv. Sapientum)
Bananas are commodities that are easily cultivated and developed in Indonesia. Optimizing plant growth is carried out through organic fertilizer and Arbuscular Mycorrhizal Fungi (AMF). This research aims to get the right type of organic fertilizer and AMF and understand whether there is an interaction between organic fertilizer and AMF dose to increase the growth of the banana plant Raja Bulu of tissue culture. The research was located in the experimental field of the Faculty of Agriculture, University of Sebelas Maret, Karanganyar. The research design used was a factorial, completely randomized design with a combination of 2 factors. The first factor is the type of organic fertilizers goat manure, cow manure, vermicompost, and compost. The second factor is the dose of AMF 0 g, 5 g, 10 g, and 15 g. The data obtained were tested statistically by statistical analysis with ANCOVA based on the F test level of 5%. If it had a real effect, further tests were carried out using DMRT with a 5% level. The variables observed were plant height, number of leaves, leaf width, leaf length, mycorrhizal infection, and stem diameter. Results showed an interaction between the types of organic fertilizer and the doses of AMF against the diameter of the stem of the plant of banana Raja Bulu. Goat manure can increase the growth of banana Raja Bulu better than the treatment of compost fertilizer. AMF dosage treatment of 5 g to 15 g per plant has not increased the growth of the banana Raja Bulu.
A real-time image analysis for cherry fruit classification from colour features
An image analysis algorithm for the classification of cherries in real time, by processing its digitalized color images, was developed, and tested. A set of five digitalized images of color pattern, corresponding to five color classes defined for commercial cherries, was characterized. The algorithm performs the segmentation of the cheery image by rejecting the pixels of the background and keeping the image features corresponding to the fruit colored area. Histogram analysis was carried out for the RGB and HSV color spaces, wherein Red and Hue components showed differences between each of the specified color patterns, of the exporting reference system. This information allowed developing a hybrid Bayesian classification algorithm, based on the components R and H, and testing its accuracy with a set of cherry samples, within the color range of interest. The algorithm was implemented by means of a real time C++ code in Microsoft Visual Studio environment. When testing, the algorithm it showed 100% of effectiveness in classifying a sample set of cherries, pertaining to the five standardized cherry classes. The components of the hardware-software system for implementing the methodology are low cost, which permits an affordable commercial deployment.
Study on Feature Extraction of Pig Face Based on Linear Discriminant Analysis
Individual identification and behavioural analysis of pigs is a key link in the intelligent management of a piggery, for which the computer vision technology based on application and improvement of deep learning model has become the mainstream. However, the operation of the model has high requirements to hardwares, also the model is of weak interpretability, which make it difficult to adapt to both the mobile terminals and the embedded applications. This study proposes to first use the LDA method to extract the main features of the pig’s face, and then conduct an individual recognition test based on the face image, and reach an average accuracy of 64.9%, This method not only reduces the computational complexity but also is of strong interpretability, so it is suitable for both the mobile terminals and the embedded applications. In some way, this study provides a systematic and stable guidance for livestock and poultry production.
Agricultural Engineering: A Way Towards Brighter Future
Agricultural engineering is the branch of engineering that considers the engineering techniques in agriculture to enhance the productivity, resource utilization, pre and post-harvest operations. The three major sub-discipline of agriculture engineering are, farm machinery and energy in agriculture, agricultural structure and process engineering, irrigation and soil & water conservation engineering. It can help environment by sustainable use of farm input and energy in agriculture, results in; increased production, yield, best quality of farm produces and reduction in farm wastage. In a nutshell, incorporating the advanced or innovative technologies such as sensors, AI, robotics, machine learning etc., in the current farm mechanization scenario, improves the overall agricultural productivity by reducing the human drudgery. The paper discusses about the future of agricultural engineering and how it going to help in near future.
