Expt. Station during the years of 2000-2003. The treatments were based on the cumulat...
abstract accurate prediction of hourly minimum temperature is required for various crop models which simulate photosynthesis and transpiration. such data can be used for crop protection and reducing the crops injuries due to freezing as well. our objective of this study is employing trigonometric and pattern recognition (k-nn) approaches to evaluate their potential in prediction of hourly tempe...
introduction intercropping, the agricultural practice of cultivating two or more crops in the same space at the same time, is an old and commonly used cropping practice which aims to match efficiently crop demands to the available growth resources (agegnehu et al., 2006; dhima et al., 2007). intercropping of chickpea with linseed reduced the chickpea yield by 60.3%, although linseed occupied on...
