A Systems Analysis on Forage Production (I)

Modeling of Hay Production Systems

Abstract

1) The interrelationships of forage production process for making hay were analyzed. The structure of the production systems consist of grass growth, field curing for hay making, field harvesting, baling and transporting concerned with conditions of weather and soil moisture. (Fig. 1)
2) It becomes easy to make and describe models of agricultural production systems by using the block diagram notations shown in Fig. 2.
3) The submodels of the forage production systems which were the grass growth model, the soil moisture estimating model, the field harvesting model, the baling model and the transporting model, were developed by the block diagram method. (Fig. 3, Fig. 5, Fig. 7, Fig. 8, Fig. 9)
4) The grass growth submodel and the soill moisture submodel were applied successfully in estimating the values. (Fig. 4, Fig. 6)
5) The computer simulation model which could simulate hay production was developed. (Fig. 10)
