I remember a US colleague commenting, in the mid 1980s, on the predilection of deans and other university managers for assessing academic statisticians’ performance in terms of the numbers of papers they published. The managers, he said, “don’t have many skills, but they can count.” It’s not clear whether the management science of assessing research performance in universities has advanced grea...

Objective: Citrus (Citrus reticulata) is one of the most important horticultural plant in Iran and weed management throuth ecological methods such as cover crop is a proper option in orchard management practices. Methods: The experiment was designed as a split plot on the base of complete randomized block design with four replications in Mazandaran Province, Sari, Voushka county from 2...

All agricultural producers face recurring risks, significant among them being production risk. Many factors contribute to production risk, including adverse weather conditions such as drought or floods, fires, insects or pests, and disease. These events can devastate a crop, significantly reducing yield and farmer revenue. Since the only way to completely avoid all production risks is to stop p...

The quick and accurate acquisition of crop growth parameters on a large scale is important for agricultural management and food security. The combination of photographic and wireless sensor network (WSN) techniques can be used to collect agricultural information, such as leaf area index (LAI), over long distances and in real time. Such acquisition not only provides farmers with photographs of c...

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 ...
