Nutrient Uptake of Maize Affected by Nitrogen and Potassium Fertility in a Humid Subtropical Environment
Nitrogen (N) and potassium (K) fertility management of maize (Zea mays L.) in the humid subtropical Mississippi Delta may differ from a temperate climate because of its use in rotation with cotton (Gossypium hirsutum L.), soil temperatures rarely falling to 08C, and heavy winter rains that facilitate nutrient losses. An experiment to determine the [N] (concentration 1⁄4 [ ]), phosphorus [P], [K...
متن کاملMaize productivity and nutrient use efficiency in Western Kenya as affected by soil type and crop management
Low soil fertility and high weed infestation are the main culprits for the declining maize production inWestern Kenya. Technology packages to address these constraints exist, but their effectiveness is likely to be influenced by variability in soil types and farm management practices in the region. Trials were conducted during the 2008/2009 cropping seasons to investigate the nutrient use e...
متن کاملFoliar Fertilization: Mechanisms and Magnitude of Nutrient Uptake
Foliar fertilization is a widely used method used to supplement soil applications to improve the yield and quality of field crops. However, questions and uncertainty surround this practice. Numerous field trials have clearly demonstrated the uptake of foliar-applied nutrients by leaves and subsequent translocation to the fruit. In cotton, foliar-applied N was rapidly absorbed by the leaf (30% w...
متن کاملPotassium and Sodium Uptake by Sugarbeets as Affected by Nitrogen Fertilization Rate, Location, and Year*
Received for Publication October 28, 1985 INTRODUCTION Fertilization of sugarbeets (Beta vulgaris L.) with potassium (K) is generally not recommended in the intermountain areas of the western United States. This is attributable to the general abundance of available K and sodium (Na) in the soils of this region, irrigation water often containing significant K and Na concentrations (7), and the l...
متن کاملStimulated fine root growth benefits maize nutrient uptake under optimized nitrogen management
Optimized nitrogen (N) management reduces total N application without sacrificing cropyield. However, the underlining mechanisms have not been well investigated, especially lackingthe evidence from roots. Here we performed a two-year field experiment with maize grownunder zero-N, conventional N and optimized N applications and examined grain yield, N,phosphorous (P) and potassium (K) uptake and...
