Simulating mustard crop phenology and productivity with InfoCrop-Mustard model under temperature increase scenarios

Abstract

The InfoCrop-mustard model was calibrated and validated using field experiment conducted during 2010-11 to 213-14 at research farm of Punjab Agricultural University Ludhiana, Punjab, having three dates of sowing (25thOctober, 5thNovember and 15thNovember) and three crop cultivars (PBR 91, Hyolla PAC 401 and GSL 1). The simulated crop phenology and seed yield agreed fairly well with field observations. The validated model was used to simulate the response of mustard to increase in temperatures on crop productivity. The seed yield decreased linearly as a result of increase in maximum and minimum temperatures. The study revealed that the InfoCrop-Mustard model can be used to predict crop phenological events and productivity under presumptive climate change scenarios in central Punjab.
