Five Decades Of Agricultural Policies In Nigeria: What Roles Has Statistics Played?, Akinboyo O. I

Bullion

All over the country and internationally, the publications of the Central Bank of Nigeria (CBN) such as the Annual Report and Statement of Accounts, the Statistical Bulletin, Economic and Financial Review, the Bullion and Nigeria: Major Economic and Banking Indicators and those of the National Bureau of Statistics (NBS) have become a veritable source of data and reference materials on Nigeria. Without basic i n f o r m a t i o n o n e c o n o m i c developments, it would be very difficult for policy makers to assess economic performances. The f o …


Burnt Harvest: Penobscot People And Fire, James Eric Francis Sr. Oct 2008

Burnt Harvest: Penobscot People And Fire, James Eric Francis Sr.

Maine History

The scientific and ethnographic record confirms the fact that in southern New England, Indians used fire as a forest management tool, to facilitate travel and hunting, encourage useful grasses and berries, and to clear land for agriculture. Scholars have long suggested that agricultural practices, and hence these uses of fire, ended at the Saco or Kennebec, with Native people east of this divide less likely to systematically burn their forests. This article argues that Native people on the Penobscot River used fire, albeit in more limited ways, to transform the forest and create a natural environment more conducive to their …

From Agriculture To Industry: Silk Production And Manufacture In Maine 1800-1930, Jacqueline Field Oct 2008

From Agriculture To Industry: Silk Production And Manufacture In Maine 1800-1930, Jacqueline Field

Maine History

Sericulture or silk production is an agricultural activity that involves mulberry cultivation, raising silkworms, and reeling (unwinding) filament (raw silk) from cocoons. Silk manufacture involves a mechanical means of throwing (spinning) raw silk into usable threads and making textiles. This article examines Maine’s role in the American silk industry from early sericulture, mulberry growing, and small-scale hand production to twentieth-century industrialized manufacturing and the production of hitherto unimaginable quantities of silk fabrics. Most specifically, the objective is to show that although Maine’s participation in this effort may not have been as dominant or as well-documented as that of other New …

Global Economics Of Nutrient Cycling, Bert H. Janssen, Oene Oenema Jan 2008

Global Economics Of Nutrient Cycling, Bert H. Janssen, Oene Oenema

Turkish Journal of Agriculture and Forestry

This paper briefly discusses global human requirements of protein nitrogen (N) from crops and animals, and then estimates the need for fertilizer N as a function of N use efficiency, and the recycling of N from animal manure and sewage wastes. These estimates are based on various assumptions and simple calculations. Results suggest that globally only 1% of N input is retained, 28% is lost to the wider environment, and some 70% is potentially available for recycling via manure and sewage. In addition, large amounts of nutrients recycle via crop residues. In practice, only a fraction of this potential is …


The Effect Of Micronutrients In Ensuring Efficient Use Of Macronutrients, Mohammad Jafar Malakouti Jan 2008

The Effect Of Micronutrients In Ensuring Efficient Use Of Macronutrients, Mohammad Jafar Malakouti

Turkish Journal of Agriculture and Forestry

Micronutrient deficiency is widespread in many Asian countries due to the calcareous nature of soils, high pH, low organic matter, salt stress, continuous drought, high bicarbonate content in irrigation water, and imbalanced application of fertilizers. Some of the adverse effects of micronutrient deficiency-induced stress in plants include low crop yield and quality, imperfect plant morphological structure (such as fewer xylem vessels of small size), widespread infestation of various diseases and pests, low activation of phytosiderophores, and lower fertilizer use efficiency. The absence of micronutrient fertilizers results in inadequate absorption of trace elements by plants, which causes substantial yield losses in …

Field Resistance Of Wheat (Triticum Aestivum L.) Genotypes From Different Countries To Leaf Rust (Puccinia Triticina), Beyhan Akin, Nusret Zenci̇rci̇, İzzet Özseven Jan 2008

Field Resistance Of Wheat (Triticum Aestivum L.) Genotypes From Different Countries To Leaf Rust (Puccinia Triticina), Beyhan Akin, Nusret Zenci̇rci̇, İzzet Özseven

Turkish Journal of Agriculture and Forestry

Puccinia triticina causes leaf rust in wheat and results in severe yield losses in mild wheat growing areas of Turkey: Thrace, Marmara, Mediterranean, and Çukurova. A feasible way to avoid any damage is to grow slow rusting cultivars. We evaluated 94 wheat genotypes from different countries and 39 leaf rust differentials for their reactions to leaf rust field epidemics. Slow rusting, though, requires both the prediction of Lr genes in the greenhouse and an effective screening of genotypes against the leaf rust field epidemics; the evaluation at the sites regularly favoring leaf rust epidemics like Adapazarı is also possible. Various …
