Abstract:
... Harvesting is one of the most complex field operations for grain producers requiring route planning that is subject to change based on spatial crop yield and scheduling with support vehicles. Inefficient routing increases operation time which lead to negative impacts including: increased labor cost, crop loss, and unnecessary hours put on expensive machinery. In addition to increased time, ineffic ...

Abstract:
... Crop diseases and insect pests are major agricultural problems worldwide, because the severity and extent of their occurrence causes significant crop losses. In addition, traditional crop pests recognition methods are limited, ineffective, and time-consuming due to the manual selection of the useful feature sets. This paper introduces a crop pest recognition method that accurately recognizes ten c ...

Abstract:
... Fall armyworm (FAW), one of the most important pests of maize in Latin America, suddenly appeared in Africa in 2016 and spread rapidly. Estimates of crop losses due to FAW are essential in order to compare the impact of these losses with the cost of controlling FAW and advise appropriate technology dissemination and policy. In this study, therefore, crop losses due to FAW in 2017 and 2018 were est ...
