Assessment of the harvest wheat yield by CROPSYST model
Journal Title: Advances in Agriculture & Botanics - International Journal of the Bioflux Society - Year 2011, Vol 3, Issue 2
Abstract
An experiment was performed to assess the wheat harvest yield using a CROPSYST model in 2008-2009 at Rashmijan zone, the northern part of Fars province, Iran. The experiment was performed in a randomized complete block design and were conducted under treat of four irrigation levels (I1, I2,I3, I4) in three replicates. Irrigation were done by a usual cycle of zone irrigation at 20% tension, 40% tension and without irrigation (dry land farming). Finally, the statistical analysis showed that, the simulation efficiency using CROPSYST model for yield, stalk and biological yield, are 0.91, 0.82 and 0.94, respectively. Notably, the investigations of yield, stalk and biologic yield showed a high correlation among yield, stalk and biologic yield (0.93, 0.95 and 0.95, respectively) which confirmed the highest accuracy of anticipated operation by using CROPSYST model. As a result, this model is evaluated as a desirable model to anticipate the harvest operation in the Marvdasht zone.
