Effect of Fall and Spring Applied Nitrogen Fertilizer on Growth and Yield of Sugarbeets *
Received for Publication July 27, 1984 INTRODUCTION The time and amount of nitrogen (N) uptake affects both root and extractable sucrose yield of sugarbeets (Beta Vulgaris L.). Either excessive or late N fertilizer applications and subsequent plant N uptake from applied•or residual N sources cause an increasing proportion of the photosynthate to be used for top growth at the expense of both roo...
متن کاملTile Drainage Nitrate Losses and Corn Yield Response to Fall and Spring Nitrogen Management.
Nitrogen (N) management strategies that maintain high crop productivity with reduced water quality impacts are needed for tile-drained landscapes of the US Midwest. The objectives of this study were to determine the effect of N application rate, timing, and fall nitrapyrin addition on tile drainage nitrate losses, corn ( L.) yield, N recovery efficiency, and postharvest soil nitrate content ove...
متن کاملIrrigated hard winter wheat response to fall, spring, and late season applied nitrogen
High yielding irrigated hard red winter wheat (HRW, Triticum aestivum L.) is frequently low in protein and marketed at a discount. Protein is affected by available nitrogen (N) but few published reports relate to N fertilization practices for producing high yielding irrigated hard red winter wheat with acceptable protein in arid environments. A three year study (1985–1987) was conducted (1) to ...
متن کاملRoot-zone temperature and nitrogen affect the yield and secondary metabolite concentration of fall- and spring-grown, high-density leaf lettuce.
BACKGROUND Understanding the effects of temperature and nitrogen levels on key variables, particularly under field conditions during cool seasons of temperate climates, is important. Here, we document the impact of root-zone heating and nitrogen (N) fertility on the accumulation and composition of fall- and spring-grown lettuce biomass. A novel, scalable field system was employed. RESULTS Dir...
متن کاملLiving Mulches Eggplant Growth and Yields in Living Mulch and Monocultures
INTRODUCTION The primary limitations of conventional weed control programs include a heavy reliance on capital intensive, toxic, and non-renewable resources (pesticides and petrochemicals) to manage weed competition. Weed emergence from the soil top layers is facilitated by the continuous disturbance created through cultivation, irrigation, pesticide applications, machinery, and other cultural ...
