Yam (Dioscorea spp.) is a tuber crop grown for food security, income generation, and traditional medicine. This crop has a high cultural value for some of the groups growing it. Most of the production comes from West Africa where the increased demand has been covered by enlarging cultivated surfaces while the mean yield remained around 10 t tuber ha-1. In West Africa, yam is traditionally culti...

A four-year rotation is desirable for potatoes. Proper rotation of crops is one necessary practice for avoiding the holding over of potato diseases in the soil. For potato wilt control at least a four-year rotation should be used. The one shown here makes use of corn, grain, clover, and potatoes. The best basic crop rotation for Western Oregon is grain, clover seed, clover hay, and a cultivated...

To study the behaviour of phosphorus (P) sorption in the agricultural soils of Khoy region and the effect of long-term cultural management with the application of poultry manure on the P sorption parameters, bath experiments were carried out with 16 soil samples (8 cultivated and 8 virgin soils) and 9 initial P concentrations from 0 to 30 mg L-1 in 0.01M CaCl2 as a background solution. After eq...

The present work was conducted to elucidate the effect of different soil mediums in various ratios on seed germination efficiency and growth of seedling of Simmondsia chinensis under in vivo conditions. The highest germination (94%) was recorded for seeds cultivated in S1 medium containing desert soil and Farm Yard Manure (FYM) (2:1) followed by S4 medium (90%) having desert soil, clay, FYM (1:...

An investigation was carried out for fifteen plant species, cultivated widely as vegetable crops in Bangladesh, belonged to six different families to measure their affinity in harbouring symbiotic association with mycorrhizal fungi. Fourteen out of the fifteen species were having developed VA-mycorrhizal colonization in their root tissues with a range of 7% to 98%. All the soil samples tested w...

We aim to model and visualize the evolution of the surface structure of a cultivated soil surface during rainfall. In this paper, we briefly present our model, based on an Extended Cellular Automaton, and the different simulated processes. Among these processes, we focus on runoff which is of high relevance as it drives the evolution of the soil surface structure by transporting anddepositing t...
