Crop rotation modelling
For use in an Internet application on whole farm modelling we needed to determine a reasonable crop rotation given only the crops in the rotation and the number of hectares of each crop. The crop rotation problem considered in this paper is therefore that of determining hectares of precrops for each crop. Crop rotation modelling in general is traditionally done by using linear programming. In t...
متن کاملHybrid Metaheuristics for Crop Rotation
This work presents a mathematical model adapted from literature for the Crop Rotation Problem with Demand Constraints (CRP-D). This highly complex combinatorial problem is devised to find a vegetable planting program that takes into account green fertilization restrictions, the set-aside period, planting restrictions for neighboring lots and for crop sequencing, demand constraints, while, at th...
متن کاملStructure of weed communities occurring in crop rotation and monoculture of cereals
A strict field experiment with crops sown in crop rotation and monoculture wascarried out in the years 1988-2012 at the Experimental Station Uhrusk belonging tothe University of Life Sciences in Lublin, south-eastern Poland. The study wasaimed at evaluating the structure of weed communities occurring in crop rotationand monoculture of cereals. The highest weed density m-2 was determined inthe s...
متن کاملThe ability of layered double hydroxides for nitrate absorption and desorption in crop and fallow rotation
BACKGROUND AND OBJECTIVES: This study aims down to evaluate the ability of chloride magnesium- aluminium- layered double hydroxides (4:1) for nitrate adsorption from the soil solution in successive cropping periods. METHODS: The study was conductedunder long-term cropping periods, including first crop): bell pepper; second crop: mentheae; third crop: cher...
متن کاملProductivity and economic efficiency of wheat in rotation with cotton
ABSTRACT- Crop rotation has many benefits for agro-ecosystems production. In order to evaluate two current rotation systems of wheat (Triticum aestivum L.) production in Kamalabad region of Fasa, an experiment was conducted during 2015-2016 growing season. The rotation systems were fallow-wheat and cotton (Gossypium spp.)-wheat. Research plots were arranged as a randomized complete block design...
