Firm turnover under asymmetric information: Tanzania's agro‐dealer sector

American Journal of Agricultural Economics, EarlyView.
Abstract We study firm turnover (i.e., entry and exit) and its consumer implications in a market characterized by asymmetric information. Using a three‐round census of agro‐dealers in Tanzania's Morogoro Region, we document annual firm entry and exit rates of 33% and 17%, respectively.

EFFECT OF SOIL POTASSIUM LEVELS AND DIFFERENT POTASSIUM FERTILIZERS ON YIELD, MACROELEMENT AND CHLORIDE NUTRION STATUS OF APPLE TREES IN FULL FRUITION PERIOD

Acta Scientiarum Polonorum: Hortorum Cultus, 2011
The experiment was established in the spring 1999 on lessive soil developed from light boulder clay. Apple trees of Golden Delicious cv. on M.26 rootstock were planted in 3.5 × 1.2 m (2381 trees·ha-1) spacing. Research involved the effect of diversified

Effect of potassium fulvate on continuous tobacco cropping soils and crop growth

Frontiers in Plant Science
Long-term continuous cropping of tobacco causes dysbiosis of soil microbial communities, the imbalance of soil nutrients, and the increase of pathogenic bacteria, which will slow the growth and development of tobacco plants, reduce the production quality,
