Nitrogen use efficiency and yield in response graft bell pepper cultivars

Abstract

In this investigation, characterize of the efficient use of nitrogen (EUN) through of the analyses of key biochemical and physiological indicators involved in NO3- reduction and fruit production of Capsicum annuum L. taking advantage of the cultivar/rootstock relationship, were evaluated through crop cycle 2013. The combinations were: Orangela/Terrano (O/T), Janette/Terrano (J/T), Fascinato/Terrano (F/T), Fascinato/Robusto (F/R), Sweet/Robusto (S/R). The horticultural crop were under agriculture net and harvested on three specifics sampling dates. The results showed statistical differences (p ≤ 0.05) in grafted cultivars for EUN and yield. The greatest N assimilation was presented with the combination Fascinato/Robusto, which coincided with the maximum yield of all cultivar/roostock combinations evaluated. Hence grafting bell pepper plants has been used per decades as a quick, ecological and effective technique to improve EUN, which has beneficial implications to mitige the severe contamination of vital natural resources and a sustained and healthy crop production.
