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...

This paper describes and generalises experiences from two cases of production system development in the Swedish context. We have observed the successful application of ergonomics to be related to the lack of coordination of human factors across groups responsible for different stages of the production system design process. This problem is magnified by the tendency for ‘ergonomics’ to be the re...

Aeroponic culture is an alternative method for optimizing growth of different plants in controlled conditions. Aeroponic systems are an efficient tool for the root studies and improving medicinal root production. In order to study the feasibility of valerian (Valeriana officinalis L.) production in aeroponic systems and assessing the effects of different NAA concentrations (0, 0.1, 0.3, and 0.5...

controlled environment may be adopted for a rapid multiplication of a large number of potato seed tubers. the controlled environment prevents seed tuber degeneration which may occur under field conditions. the objective of this study was to introduce new mini-tuber production system with high multiplication rate and low production cost. to evaluate the performance of culture systems in terms of...

an artificial neural network (ann) approach was used to model the wheat production. from an extensive data collection involving 40 farms in canterbury, new zealand, the average wheat production was estimated at 9.9 t ha-1. the final ann model developed was capable of predicting wheat production under different conditions and farming systems using direct and indirect technical factors. after exa...

The trend towards higher performance mechanical systems has naturally led to the need to design such systems in an optimal fashion. Lighter components and higher operating speeds both demand a level of design a step above that provided conventionally. This paper describes a research effort aimed at developing the methodology for such system design. The methodology is based on accurate computer ...

the effect of the presence of perforations on he stresses of a plate is a problem which is of great interest in structural design and in the mathemattical theory of elasticity. among the many hole patterns that are likely to require consideration is the ring of equally spaced circular holes. the present worke investigates stress & strain analysis of a thin isotropic circular plate containing a ...
