Cultivo do tomateiro cereja sob irrigação com águas salinas e adubação nitrogenada

Autoria SCIMAGO INSTITUTIONS RANKINGS

RESUMO

Este trabalho foi desenvolvido entre agosto de 2013 e janeiro de 2014 objetivando avaliar o crescimento e a produção do tomateiro cereja cultivado sob irrigação com águas salinas e adubado com distintas doses de nitrogênio em ensaio conduzido em lisímetros de drenagem sob condições de casa de vegetação da UFCG, Pombal-PB. O delineamento estatístico utilizado foi o de blocos ao acaso, em arranjo fatorial 5 x 4, com três repetições cujos tratamentos constaram de cinco níveis de condutividade elétrica da água (0,3; 1,5; 2,5; 3,5 e 4,5 dS m^-1) e quatro doses de N (60, 100, 140 e 180 mg kg^-1). As variáveis de crescimento e produção do tomateiro cereja decrescem de forma linear a partir da salinidade da água de irrigação 0,3 dS m^-1; o maior tempo de exposição das plantas ao estresse salino ocasionou as maiores reduções sendo a massa das raízes, a área foliar e o número de cachos as variáveis mais sensíveis; a maior altura de planta aos 125 dias após o transplantio foi obtida com dose de N de 139 mg kg^-1 de solo; doses crescentes de nitrogênio reduziram o efeito da salinidade sobre o crescimento do tomateiro cereja, aos 125 dias após o transplantio.
