Crop model simulates growth and yield of crop in field scale and can be used to provide useful field information for farmers, such as irrigation application dates and amount, fertilizer application dates and amount, the choose of crop variety. Researchers have used crop models for many years, but they have had limited success in packaging these complex models in a framework that make them easy ...

This paper summarises the result and findings of a research project, that was aiming at design and development of an information system which supports crop forecasting of major agricultural commodities in Iran. In this system, crop area estimates are generated through area frame sampling and processing of satellite data, and yields are derived through the application of crop growth simulation m...

an analysis of the stages of crop growth presents an important step in the improvement of production management. through growth analysis, planning for planting systems, fertilization, pruning operations, harvest time as well as obtaining economical yield can be more accessible. therefore, a development of mathematical models simulating plant growth would be helpful in improving crop management,...

Groundnut (Arachis hypogaea L.) is an important oilseed crop grown in our country. Majority of crop is under rainfed conditions and as a post rainy season (Rabi) crop in Andhra Pradesh. Several models are available to predict the phenology, growth and yield of groundnut crop. However, no precise models are available to validate the effects of moisture stress on groundnut and their subsequent im...

A robust crop model can assist in genetic improvement and cultural management of the crop. The objectives of this study were to describe a wheat (Triticum aestivum L.) model and to report results of its evaluation. The model simulates phenological development, leaf development and senescence, crop mass production and partitioning, plant nitrogen balance, yield formation and soil water and ...

A combination of a simple and universal crop growth simulator (SUCROS) of van Keulen et al. [van Keulen, H., Penning de Vries, F.W.T., Drees, E.M., 1982. A summary model for crop growth. In: Penning de Vries, F.W.T., Laar van, H.H. (Eds.), Simulation of Plant Growth and Crop Production. Simulation Monographs, Pudoc, Wageningen] with a water balance model (WBM) of Arora et al.

Crop yield is the result of complex interaction among factors of soil, atmosphere, plant genotype, and management practices adopted. These complex interactions of crop with various factors and of factors among themselves make the crop yield modeling a difficult task. Several methods of crop yield forecasting have been developed ranging from purely statistical to agro-meteorological to empirical...

In this paper, an intelligent control of the greenhouse in the Greenhouse Management Framework (GMF) has been designed for the purpose of increasing the farmer’s profit and promoting the ease of agricultural production. The GMF is divided into Greenhouse Control Engine and Crop Growth Engine. The Greenhouse Control Engine consists of Data Aggregator, Greenhouse Information Storage, and Greenhou...
