This study was conducted to estimate the relative profitability of Maize production under different farm size groups. Data were collected from randomly selected 74 maize growing farmers of which 25 were small, 32 were medium and 17 were large considering the scope and potentials of maize production at Kishoregonj district. To achieve the objectives of the study, descriptive statistical techniqu...
The biodiversity of the Southern Balkans, part of the Mediterranean global biodiversity hot-spot, is threatened by land use intensification and abandonment, the latter causing forest encroachment of formerly open habitats. We investigated the impact of forest encroachment on butterfly species richness, community species composition and the representation of life history traits by repeated seaso...
Our previous work demonstrated that boron (B) supplied to soybeans (Glycine max [L.] Merrill cv ;Williams 82') by a stem infusion technique increased the number of pods on branches and led to a significant yield increase. Therefore, research was continued to determine whether soil or foliar applications of B could be used to achieve the same results. Field experiments were completed with both s...
country to the economic activity existing in developed countries. Incidentally, my planning office has just finished a feasibility study for an area in the Amazon Basin where 500 families may be settled in 14,400 hectares (1 hectare = 10,000 square meters), with a loan of $16,000 (United States dollars) per family extending over a 10-year period. After 10 years each family will have paid the lo...
In this paper we develop methods to investigate the efficiency of alternative contracts for Carbon (C) sequestration in cropland soils, taking into account the spatial heterogeneity of agricultural production systems and the costs of implementing more efficient contracts. We describe contracts being proposed for implementation in the United States and other countries that would pay farmers for ...
This paper examines the possible impact of climate change on Malaysian rice production. Using the Ricardian Method and farm household data, we have examined the effects on rice producers focusing on sharecropper adaptations and ecological causes. The principle goal of this research paper is to investigate the impact of climate variables such as temperature, rainfall and precipitation on rice pr...
Hand-applied dispensers are successfully used in mating disruption programs, but cost of labor to apply these dispensers limits their adoption. Creating hand-applied dispensers that release larger amounts of pheromone and that can be applied at lower densities per hectare could reduce the cost of mating disruption and increase its use. The effect of reducing the number of point sources per hect...
There is widespread agreement within academic literature that the NSDAP systematically and effectively targeted the rural areas beginning with the agrarian crisis in 1927/8. However, one issue is left unresolved: were specific levels of agricultural strata differently attracted to the Nazis, and if so, how? In light of the economic and political incentives offered to German peasants with differ...
The objectives of the research were (1) to analyze value biocapacity and ecological footprint in Sleman Regency; (2) measure spatial distribution bioecological carrying capacity global hectare units (global hectare); (3) formulating direction development control based on class capacity. was conducted using a quantitative approach through processing analyzing secondary data from various sources....
Tropical forest structural variation across heterogeneous landscapes may control above-ground carbon dynamics. We tested the hypothesis that canopy structure (leaf area and light availability) - remotely estimated from LiDAR - control variation in above-ground coarse wood production (biomass growth). Using a statistical model, these factors predicted biomass growth across tree size classes in f...
