Generalized Directional Derivatives

Generalized Directional Derivatives

Over the last fifty years, generalized second-order derivatives have been studied because it is important to state optimization conditions for nonsmooth functions. We recall e.g. the concept of convex subdifferential, the Clarke gradient for locally Li...

Ecological weed management is essential component in weed control when herbicide use is limited or prohibited in cropping systems.Herbicide use can be limited in controlling wild oat (Avena fatua L.) in oat (Avena sativa L.) cultivations as they are ge...

Sweet Pepper (Capsicum annum L.) Seedlings on Different Growth Media

Sweet Pepper (Capsicum annum L.) Seedlings on Different Growth Media

Sweet pepper seedlings germinate slowly and erratic on soil even under optimal conditions. The slow growth of the seedlings was attributed to absence of nutrients in the soil. This prolongs the time the plant stays in the nursery, delays farm operation...
