  • Yield editor Software for removing errors from crop yield maps

    Yield maps are a key component of precision agriculture, due to their usefulness in both development and evaluation of precision management strategies. The value of these yield maps can be compromised by the fact that raw yield maps contain a variety of inherent errors. Researchers have reported that 10 to 50% of the observations in a given field contain significant errors and should be removed. ...

  • A call to conserve crops’ wild cousins

    Wild cousins aren’t always appreciated at family gatherings. But when it comes to crops, the opposite is often true: Plant breeding has historically relied on genes from plants growing in the wild as a source of diversity that can be introduced into crop plants to produce new crop varieties that are more resilient, nutritious and productive than those currently cultivated. As human ...

  • A simple spectral index using reflectance of 735 nm to assess nitrogen status of rice canopy

    Spatial distribution of canopy N status is the primary information needed for precision management of N fertilizer. This study demonstrated the feasibility of a simple spectral index (SI) using the first derivative of canopy reflectance spectrum at 735 nm (dR/d|735) to assess N concentration of rice (Oryza sativa L.) plants, and then validated the applicability of a simplified imaging system ...

  • Validation of molecular markers associated with net blotch resistance and their utilization in barley breeding

    With the advancement of molecular marker technology and computer software, mapping quantitative trait loci (QTL) for complex traits in agricultural crops is frequent; however, exploitation of these QTL in practical breeding programs is limited. Here we report the validation of molecular markers linked to net blotch resistance QTL and their utilization in a barley (Hordeum vulgare L.) breeding ...

  • On-time Pest Protection

    Farming can be a beautiful job under an open sky. But sometimes that ”open sky” determines the flow of farming, total yield, and productivity according to the weather (rain, drought, hail, frost). Since the weather is a major factor in farming, farmers need to manage certain practices to protect their crops from bad weather conditions as well as from various insects and diseases ...
