Take home messaged from nitrogen and snap bean research:
1) Different snap bean varieties respond differently to nitrogen fertilizer applications.
2) Variations in rainfall timing cause huge differences in response to nitrogen
3) There is a huge nitrogen use efficiency decrease when nitrogen is applied in excess of 60 lb/ac, but any slight yield gains achieved with extra nitrogen can be justified from an economic perspective (i.e. the high economic value of the crop far exceeds the cost of additional nitrogen fertilizer)This article was posted in Nutrient Management.
