Based on the Entity – Relationship model (ER model) of Agricultural activities, a simulation model of the vegetative development of plants has been developed, taking into account the agricultural activities necessary for their cultivation. The agricultural crops grapes and pepper have been selected because they present different specificities such as annuals – perennials, vines (bushes) – low-stemmed and other fundamental differences. The model recreates the vegetative processes arising from the botany of pl...

Time series on quantities, areas harvested and yield average of key global crops in Bulgaria пїЅ wheat, maize, rise and soybean пїЅ are stored in multidimensional database. The developed software modules for statistical processing are embedded into database to give better operability than known software systems with Graphical User Interface. Time series on key global crops production in Bulgaria on national and regional level are studied for the period 2002-2015. Comparative data analysis on two sub-periods with t...
