Biomass Accumulation and Nutritional Requirements of Potato as Affected by Potassium Supply
(2020-09-01)
Potassium (K) supply affects the growth and tuber yield of potato (Solanum tuberosum L.) as well as the uptake and removal of certain nutrients. However, information on this is scarce or inconsistent. Thus, this study was ...
Impact of Potassium and Nitrogen Fertilization on Bahiagrass Herbage Accumulation and Nutrient Concentration
(Amer Soc Agronomy, 2017-05-01)
Bahiagrass (Paspalum notatum Flugge) is the most utilized forage for beef cattle (Bos spp.) in Florida, but there is concern that bahiagrass pastures are declining due to insufficient K fertilization. Two studies determined ...
