Intensively researching different populations of elecampane, we are able to present the results of yield achieved during three years' microexperiments (2001, 2002, 2003) realized in non-watering field crop production. Comparing the results of yield, it was concluded that all five populations had higher yield, both fresh and dry elecampane root mass, compared to standard cultivars called "Domaća".
Unstability of food production per capita and population: Asia
Faculty of Agriculture, Belgrade-Zemun (1)
The basic aims of this paper are: firstly, to set up an endogenous model of food production per capita and population; secondly, to estimate the food production per capita regression equation and population regression equation; and thirdly, to determine stability properties of food production per capita and population in Asia during the period 1967-1997. Empirical content of this model confirms the fact that movement of food production per capita and population had unstable character in Asia in the observed period.
