Using Moringa Oleifera Seed Cake and Compost as Organic Soil Amendments for Sustainable Agriculture in Valencia Orange Orchard
(2021-09-24)
This work was conducted during two consecutive seasons of 2016/2017 and 2017/2018 at the Experimental Research Station of National Research Centre at Nubaria, El Behiera governorate, Egypt. Twelve year old Valencia orange trees (Citrus sinensis L. Osbeck) budded on Volkamer lemon rootstock, grown in sandy soil under drip irrigation system as plant materials to study the effect of six organic soil amendment treatments on soil hydrophysical properties, soil water retention, soil water movement, plant nutrient contents, ...

Untersuchungen zur Bedeutung phytotoxischer Sirodesmine und zur induzierten Seneszenz in Interaktionen von Phoma lingam mit Brassica-Arten
(1995)
Ziel dieser Arbeit war es, die Bedeutung phytotoxischer Sirodesmine in Interaktionen von Phoma lingam mit Brassica napus und Brassica juncea zu untersuchen. Ein weiteres Interesse galt dem Einfluß einer induzierten Seneszenz auf die Resistenzeigenschaften.
Zur Isolierung von Sirodesmin PL wurde ein Säulenchromatographieverfahren auf Kieselgelbasis entwickelt. Mit dieser Methode konnten bis zu 100 µg Sirodesmin PL in reiner Form pro Arbeitsgang chromatographiert werden.
Sirodesmin PL wurde in verschiedenen Dosierungen ...

Variation in baobab (Adansonia digitata L.) root tuber development and leaf number among different growth conditions for five provenances in Malawi
(2020-08-21)
The baobab tree is an underutilised indigenous fruit tree in sub-Saharan Africa which, at the same time is vulnerable to overexploitation in areas close to centres of demand, as currently baobab use is limited to wild, baobab trees. Baobab seedlings are known to form root tubers, but little is known about their growth characteristics and its yield potential. This study aims to investigate the root tuber and leaf development of baobab seedlings grown from seeds of five provenances, sown at three different planting ...

An Exploration on Factors Influencing Certified and Farm-Saved Seed Use: A Case Study in Turkish Wheat Farming
(2020-11-29)
Seeds are an important input for wheat-growing, as is the case for all crop production. The type and quality of seed in crop production are the first condition for productivity and accordingly certified wheat seed use is being encouraged by the government since 2005 in Turkey. This study examined the factors affecting the certified seed and farmer (farm)-saved seed use in wheat farming in Turkey. The result of the analyses showed that there is a significant difference between farmers using certified seed and farm-saved ...

Remote sensing of yield and invasive species in nature conservation grasslands invaded by Lupinus polyphyllus
(2021-07)
Extensiv bewirtschaftetes Grünland und naturnahes Naturschutzgrünland sind wertvolle Bereitsteller von Ökosystemdienstleistungen und könnten eine Schlüsselrolle in zukünftigen Managementstrategien spielen zum Schutz von Arten, die durch den Klimawandel bedroht sind. Jedoch ist extensives Grünland, wie viele andere Ökosysteme, bedroht durch die Ausbreitung invasiver Arten, welche einen großen Einfluss auf den Verlust der Biodiversität haben.
Um den Herausforderungen unserer Zeit zu begegnen, sollten Innovationen in ...

The effect of edible coating with combined Thymus Vulgaris extract and glycerol monoestearate on oyster mushroom ҆s shelf life
(2020-07-30)
Shelf-life of mushrooms is very low, because of several characteristics, such as their thin epidermal structure and high respiration rates. They tend to lose their quality after harvest. Hence, mushrooms need supportive care to keep freshness. Several protective methods have been recommended. In the current study, the effect of lipid-edible coating with different doses of glycerol monoestearate and thyme extract, for the extending of edible mushroom’s shelf life was evaluated. After, preparation of aqueous thyme ...

Protein and iron source snack bar made from Mlanding Tempeh – A fermented Lamtoro (Leucaena leucocephala)
(2022-08-31)
Mlanding tempeh is an Indonesian fermented food made from Lamtoro (Leucaena leucocephala), a tropical legume that contains complete nutrients and has high productivity and ability to adapt to dry climates. This traditional treatment seems improve its nutritional value, particularly the protein profile. However the short shelf life and low acceptance hinder this food to support community nutrition. This study introduced an effort to process this indigenous fermented legume into a snack bar which has better acceptance ...

Rural farmers’ learning of weed management methods in Malaysia
(2022-08-31)
Malim Nawar in Kampar District, Malaysia, is a potential major production site for modern high-technology farms by 2030. To achieve this, a significant increase in intensive agricultural activities and weed management practices is required. To develop strategies and achieve the goals of sustainable agriculture, the present study used a semi-structured questionnaire survey to assess farmers’ perception of weeds, their sources of information, and their reasons for willingness or unwillingness to adopt non-chemical ...
Dissertation
Towards crop communities: exploring wheat diversity, wheat-pea species mixtures and farming practice in a food system context
(2022-06)
This thesis combines experimental work on heterogeneous crop populations (HP) and species mixtures (SM) with a social scientific and participatory approach. Chapter 1 introduces crop communities as a concept to integrate multiple approaches to diversify farming systems. HPs provide intraspecific and SM interspecific diversity in crop communities. A key challenge for the genetic improvement of HPs, especially for root traits is to combine effective selection to improve HPs while maintaining intraspecific diversity. ...
