“…A number of models have been developed to simulate the production of lettuce dry matter (Sweeney et al, 1981;Critten, 1991;Van Henten, 1994;Pearson et al, 1997;Seginer et al, 1998). A two-compartment mechanistic model originally proposed by Sweeney et al (1981) has been validated and extended by others (Van Henten, 1994;Van Henten and Van Straten, 1994;Pearson et al, 1997), who found that it could make reasonable predictions for lettuce dry matter accumulation.…”

“…NICOLET lettuce growth model, Seginer et al (1998Seginer et al ( , 1999, is based on the complementary properties of nitrate and carbon in the vacuoles. The calibration of the model was considered in Van Straten et al (1999).…”

Planned experiments are usually expected to provide maximal benefits within limited costs. However there are known difficulties in optimal design of experiments. They are related to the case when only limited number of parameters could be estimated, because available experiments are the non-informative. The useful method for this case is considered based on the dominant parameters selection procedure (DPS). The methodology is illustrated here with data from five planned experiments related to the NICOLET lettuce growth model. The maximal number and the list of estimated parameters are determined while the conditional number of the information Fisher matrix (modified E-criterion) is kept below a given upper constraint.

“…The idea was generalized in [18] where it was assumed that the pool size of nonstructural carbohydrates, including soluble sugars, is determined by the balance between source activity, i.e. the supply by photosynthesis, and sink activity, i.e.…”

“…As expected, decreased concentrations of nitrate coincided with increased soluble carbohydrate levels in all cases. A dynamic model, formulated on the basis of this new concept [18], was able to simulate published results of seasonal effects on the nitrate concentration in lettuce [5] with reasonable accuracy. An optimal control policy including the reduction of N-supply was presented in [13,8].…”
