In agricultural production, land-use decisions are components of economic planning that result in the strategic allocation of fields. Climate variability represents an uncertainty factor in crop production. Considering yield impact, climatic influence is perceived during and evaluated at the end of crop production cycles. In practice, this information is then incorporated into planning for the ...

The farmer requires detailed information on crop stress conditions in order to manage the crop growth. This information may be acquired by low granular satellite images to coarsely identify areas of interest within the field followed by ground measurements carried out by robotic surveying platforms for plant identification and segmentation. A novel concept for creating rational behaviors of sur...

A research was conducted in Fars province Agricultural Research Center in Zarghan area from 1999 to 2002 to determine the water requirement and crop coefficient of wheat, applying lysimeter. The results indicated that the water requirements of wheat were 720, 712 and 674 mm in the years of 1999-2000, 2000-2001 and 2001-2002, respectively. Using Penman-Monteith method for estimating reference ...

In this paper, we study the problem of planning growth crops on shelves in vertical farming cabinets under controlled conditions. By adjusting temperature, humidity, light, and other environmental conditions different parts cabinets, a planner must ensure that crop is able to satisfy some deterministic demand. We prove be NP-hard propose an integer programming formulation capture real-life oper...

a substantial global increase in the demand for food of animal origin, while also aggravating the competition between crops and livestock (increasing cropping areas and reducing rangelands). The livestock revolution 1 is stretching the capacity of existing production, but it is also exacerbating environmental problems. Therefore, while it is necessary to satisfy consumer demand, improve nutriti...

Assessment of soil and vegetation properties is one of the main objectives of radar remote-sensing applications. The parameters of soil dielectric constant, crop height and extinction coefficient etc are very important for planning of earth resource utilization and the prediction of environmental changes. Although, a lot of work has been already done in this direction, no robust operational met...

Simulation of crop systems has evolved from a neophyte science into a robust and increasingly accepted discipline. Our vision is that crop systems simulation can serve important roles in agriculture and environment. Important roles and uses of crop systems simulation are in five primary areas: (1) basic research synthesis and integration, where simulation is used to synthesize our understanding...

Estimation of crop production can be a very useful tool while planning a nation’s agriculture. The use of statistical techniques in developing such tools is a popular and well studied problem. In this paper, we present a statistical model that predicts the total crop production for a geographical region, given the season of harvest and the total land used. We apply this model on four major crop...
