Utilizing genotypic traits of potato for drought resistance and modeling secured production by APSIM
Abstract
Potato is the 3rd most important crop in the world food production. It is also considered as an important cash crop in Bangladesh. The main objective of the study is to examine transpiration efficiency (TE) in potato cultivars in response to drought and make use of this trait for minimizing water stress effects at advanced growth stages and utilizing stored soil moisture during the dry period or water limited condition. The empirical results will pave the way for a modeling initiative with APSIM for how the incidence and the degree of drought may affect potato production in different regions today and in future under changing soil water scenario. The experiment will explore cultivars and evaluate TE under water deficit conditions or exposure to drought. Subsequently, the genetic traits and potential contribution of TE will be used to parameterize APSIM and determine how genotypes respond to make use of benefits of prolonged soil water storage. APSIM simulations will also be applied for determining crop performance and recommendations for resource utilization under different soil moisture conditions and management practices for a secured potato production in future.
