  1. 31. Autonomous navigation of an articulated vehicle in agriculture

    Författare :Saira Latif; Magnus Karlberg; Linnea Hansson; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; Machine Design; Maskinkonstruktion;

    Sammanfattning : Disrupting agricultural vehicular automation is imperative for the solutions to global as well local challenges in agricultural production system. Historically, application of scientific and technological developments through increased mechanization and precision farming have provided several opportunities for agricultural production in general and within forage handling operations.

  3. 32. Insect pollination of oilseed rape

    Författare :Sandra Lindström; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Ecological intensification of agriculture is suggested as a way to reach higher crop yields without increasing inputs that may degrade the environment. Increased insect pollination in crops, such as oilseed rape, Brassica napus, has been suggested to increase yields, but is rarely integrated in crop management. LÄS MER

  4. 33. Grain Yield and Quality Traits of Rice (Oryza sativa L.) Cultivars under Intermittent Drought and Contrasting Temperatures : physiological, biochemical and molecular characterisation

    Författare :Alphonsine Mukamuhirwa; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : Rice (Oryza sativa) has evolved in a semi-aquatic tropical environment and therefore thrives better in a water intensive system and optimal temperature between 25 and 30°C. With the future climate change, frequent droughts and heat stress are predicted to happen simultaneously in field but little is known about their combined effects on rice productivity and quality.

  5. 34. Phosphorus chemistry in managed forest soils : effects of weathering and wood ash fertilisation

    Författare :Marius Tuyishime; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Weathering and Podzolisation are key mechanisms that transform primary mineral apatite into a phosphorus (P) pool with low solubility. In addition, intensive forest harvesting removes nutrients from the soil, reducing P availability. LÄS MER

  7. 35. Nature conservation in a tropical rainforest : economics, local participation and sustainability

    Författare :Eugene Ejike Ezebilo; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : The loss of tropical forests has led to establishment of protected areas such as national parks to conserve environment. National parks often affect the livelihoods of local people, especially when they are strongly linked to natural resources. For conservation efforts in a national park to be efficient, cooperation of local people is required. LÄS MER
