Comparison with some mathematical growth models of leaf area development of bean grown (Phaseolus vulgaris L.) under different irrigation regimes

Growth, productivity and quality of plants are directly related to leaf area. Leaf area plays an important role affecting radiation interception, transpiration and photosynthesis. Some mathematical models are useful tool for analyzing the plant growth and development. The aim of the study was to compare some mathematical growth models of leaf area development of bean (Phaseolus vulgaris L.) grown under different irrigation regimes. Experiment was conducted in randomized block design with three replications in a greenhouse Application and Research, K？r？ehir Ahi Evran University, Turkey. Three irrigation regimes (50, 75 and 100 % of field/pot capacity) and four bean cultivars ("Sar？k？z", "Sazova", "K？rkgünlük" and "Gina") were performed. Leaf area measurement were done from germination to harvesting time, as total eight times. Gompertz, Weibull, Logistic and Monomolecular models were used for determining leaf areas. As comparison criteria were used the coefficient of determination (R2) and mean square error (MSE). As a result, leaf area growth was determined to vary according to bean varieties and different irrigation levels. The development leaf area of plants can be predicted by some mathematical growth models
