  1. 1. Study of evaluation metrics while predicting the yield of lettuce plants in indoor farms using machine learning models

    University essay from Högskolan i Skövde/Institutionen för informationsteknologi

    Author : Divya Chedayan; Harry Geo Fernandez; [2023]
    Keywords : machine learning; lettuce yield prediction; Regression; SVR; RF; DNN; MAE; MSE; RMSE; R-squared; Adjusted R-squared;

    Abstract : A key challenge for maximizing the world’s food supply is crop yield prediction. In this study, three machine models are used to predict the fresh weight (yield) of lettuce plants that are grown inside indoor farms hydroponically using the vertical farming infrastructure, namely, support vector regressor (SVR), random forest regressor (RFR), and deep neural network (DNN).

  3. 2. Effect of Mycorrhizal Inoculation on Growth and Nutrient Uptake by Leek (Allium porrum) fertilized with Inorganic N Combined with Saturated Polonite

    University essay from SLU/Dept. of Biosystems and Technology (from 130101)

    Author : Emmanuel Owusu Boateng; [2023]
    Keywords : Phosphorus; Arbuscular Mycorrhiza fungi; Saturated polonite; Nitrogen; Allium porrum; Sustainability; circular economy;

    Abstract : The continuous rise in global population continues to increase the demand for food. Meeting this rise in demand requires an increase in agricultural input, such as applying fertilizers, including phosphorus (P). READ MORE

  4. 3. Jämförelse mellan olika system för ogräsrensning i lökodling : autonomt ∙ Manuellt ∙ Herbicider

    University essay from SLU/Dept. of Crop Production Ecology

    Author : Markus Sollenberg; [2023]
    Keywords : Artificiell intelligens; avkastning; handrensning; herbicider; kemisk bekämpning; lök; ogräsbekämpning; robot;

    Abstract : Ogräs är ett stort problem i lökodling och kan orsaka stora skördeförluster för lantbrukaren. För att jämföra effekterna av olika metoder för ogräsrensning i lök på ogräspopulationernas marktäckning (ogräseffekt) samt lökodlingens avkastning och de skördade lökarnas storlek såddes därför ett randomiserat blockförsök med lök på Almhaga gård i Skåne, Sverige, den 13 april 2022.

  5. 4. Biostimulants : effects on root development in barley (Hordeum vulgare)

    University essay from SLU/Dept. Of Plant Biology

    Author : Alexander Lilliehöök; [2022]
    Keywords : Biostimulants; root development; barley; root length; root fresh weight; root dry weight; grain yield;

    Abstract : The use of biostimulants has increased greatly in the last 20 years. In year 2012 over 6 million hectares in Europe was treated with biostimulants and the market is expected to almost double in the coming 5 years compared to present levels. READ MORE

  6. 5. Assessing the effect of Fusarium graminearum inoculation on the root structure of Swedish winter wheat cultivars (Triticum aestivum

    University essay from SLU/Dept. of Crop Production Ecology

    Author : Fayez Altabbaa; [2022]
    Keywords : Fusarium graminearum; conidium suspension; hypha agar plug; root architecture traits; root cellar structure traits; shoot traits; genotypes;

    Abstract : Several diseases attack the wheat crop and reduce the yield, such as root disease, which causes a tremendous loss in wheat production. Root rot has a variety of causal agents, such as nematodes, viruses, and bacteria, but the most common pathogens causing wheat root rot are oomycetes and fungi. READ MORE
