1. 1. N2 fixation of three legume species in an agroforestry system

   University essay from SLU/Dept. of Soil and Environment

   Author : Hsiang-Ju Fan; [2023]
   Keywords : nitrogen; dinitrogen fixation; legumes; groundnut; stylo; pinto peanut; understorey crop;

   Abstract : Due to the strong soil erosion caused by agricultural activities and sloping landscape, agroforestry has been introduced as a potentially sustainable cropping practice in the mountainous NW Vietnam. Using legumes as understorey crops in these systems has a potential to limit erosion and smother weeds, as well as provide additional nitrogen (N) to the system. READ MORE

3. 2. Companion crops in winter oilseed rape : effects on nitrogen concentration, biomass, and prevalence of weeds at the end of autumn growth

   University essay from SLU/Dept. of Crop Production Ecology

   Author : Stina Johansson; [2023]
   Keywords : biomass; companion crops; intercropping; legumes; nitrogen concentration; organic cultivation; weeds; winter oilseed rape;

   Abstract : Intercropping can be used as a management system to promote higher yield as well as less weeds,diseases, and insect damage. Legumes are a commonly used companion crop (CC) in intercropping due to the benefit of nitrogen (N) fixation. READ MORE

4. 3. Nitrogen fixation in wheat (Triticum aestivum) : effect of Azotobacter salinestris CECT 9690 on N-accumulation

   University essay from SLU/Dept. of Soil and Environment

   Author : John Pålsson; [2023]
   Keywords : Biostimulants; Vixeran; N-uptake; N-concentration; yield; cereals;

   Abstract : Biostimulants are products that can improve nutrient availability, nutrient uptake, nutrient use efficiency and tolerance to abiotic stress with the aim to increase plant growth and yield. During the last decades, the interest in, and market for biostimulants has grown and is expected to have a large compound annual growth rate. READ MORE

   Abstract : The main purpose of this project was an attempt to modulate and simulate two existing biogas plant, situated in Lidköping and Katrineholm, Sweden and evaluate how the process reacts to certain conditions regarding feeding, layout and substrate mixture. The main goal was to optimize the existing processes to better performance. READ MORE

6. 5. Soil factors affecting plant performance of climbing beans (Phaseolus vulgaris L.) in south western Kenya

   University essay from SLU/Dept. of Soil and Environment

   Author : Hanna Williams; [2016]
   Keywords : penetrometer; resistance; soil pH; staking; CN ratio; Kisii; KALRO;

   Abstract : The south west part of Kenya is the most densely populated part of Kenya. This part of Kenya has relatively fertile soils and a favorable environment for crop production, which is why it is a major food producing area. The high population results in land scarcity with the average farm size ranging from 0.8-1. READ MORE
