Crop and Soil Responses to Post-Emergence Tillage and Weed Control in Lowland Rice by Siopongco, Joel D. L. C., Ingram, Keith T., Pablico, Paquito P., Moody, Keith

“…Beusani is a rice crop management system practised in rainfed lowland areas of eastern India whereby rice is dry-seeded, then wet-ploughed at 30–50 days after emergence and the land levelled by drawing a board across the field. Field experiments showed that beusani enhances rooting, especially in shallow soil layers, as a result of reduced penetration resistance. …”

Multitrophic interactions in cassava, Manihot esculenta, cropping systems in the subhumid tropics of West Africa by Schulthess, F., Neuenschwander, Peter, Gounou, S.

“…The effect of fertilizer and mulch across tropic level of the cassava ecosystem, i.e. the plant, the cassava mealybug(CM), the wasp Apoanagyrus lopezi and its hyperparasitoids, was studied in two field experiments planted ins southern Benin. Several cassava cultivars with different branching patterns and varying susceptibility to the cassava mealbug were planted on a sandy loamy and a sandy soil, respectively. …”

Snail control in Africa: towards a community-based environmental control by Laamrani, Hammou, Madsen, H., Boelee, Eline

“…In the present paper, community participation in snail control is discussed from three standpoints: feasibility, effectiveness as well as long-term sustainability, based on field experience in Zimbabwe, Tanzania and Morocco. The process leading to the involvement of the community appears to be a crucial factor in the success of any community based approach to control snails. …”

Risk preferences of agricultural students and their willingness to become a farmer by Nainggolan, Lukas Bonar

“…Based on a large sample with high statistical power, these results contribute to the debates on risk preferences in agriculture as well as methodological studies on the external validity of behavioral field experiments. I also discuss the impact of socio-economic background variables as they relate to generation renewal and the so-called “young farmer problem” in agriculture.…”
