Rice crop yield prediction using artificial neural networks

Abstract

Rice crop production contributes to the food security of India, more than 40% to overall crop production. Its production is reliant on favorable climatic conditions. Variability from season to season is detrimental to the farmer\u27s income and livelihoods. Improving the ability of farmers to predict crop productivity in under different climatic scenarios, can assist farmers and other stakeholders in making important decisions in terms of agronomy and crop choice. This study aimed to use neural networks to predict rice production yield and investigate the factors affecting the rice crop yield for various districts of Maharashtra state in India. Data were sourced from publicly available Indian Government\u27s records for 27 districts of Maharashtra state, India. The parameters considered for the present study were precipitation, minimum temperature, average temperature, maximum temperature and reference crop evapotranspiration, area, production and yield for the Kharif season (June to November) for the years 1998 to 2002. The dataset was processed using WEKA tool. A Multilayer Perceptron Neural Network was developed. Cross validation method was used to validate the data. The results showed the accuracy of 97.5% with a sensitivity of 96.3 and specificity of 98.1. Further, mean absolute error, root mean squared error, relative absolute error and root relative squared error were calculated for the present study. The study dataset was also executed using Knowledge Flow of the WEKA tool. The performance of the classifier is visually summarized using ROC curve

Predicting Rice Pest Population Occurrence with Satellite-Derived Crop Phenology, Ground Meteorological Observation, and Machine Learning: A Case Study for the Central Plain of Thailand

“…ANN is a type of machine learning model and is relatively competitive in terms of usefulness with conventional regression and statistical models. ANN has been successfully applied in various disciplines, such as agriculture, medical science, education, finance, management, security, engineering, trading commodity, and art [33][34][35][36][37][38][39][40][41][42]. For pest forecasting, ANN has been applied to model the pest population dynamics for the pod borer Helicoverpa armigera (Lepidoptera: Noctuidae) [43], the fruit fly Bactrocera dorsalis (Diptera: Tephritidae) [44], rice pests [45] and the paddy stem borer (Scirpophaga incertulas) [46].…”

Rice Crop Yield Forecasting Using Random Forest Algorithm SML

“…These decision trees are applied on the remaining records for accurate classification. The resultant training sets can be applied on the test data for correct prediction of crop yield based on the input attributes [19]. RF algorithm was used to study the performance of this approach on the dataset.…”

Yield Forecasting for Indian Crops with Ensemble Model

“…The accuracy of BayesNet was found to be higher than Naïve Bayes classifier. The same author applied neural network for rice yield prediction in [4]. A Multilayer Perceptron Neural Network was used to forecast and it achieved an accuracy of 97.5%.…”
