Response of tomatoes for the fresh market to NPK fertilization and split nitrogen application



Response of tomatoes for the fresh market to NPK fertilization and split nitrogen application



Agricultura Tecnica 46(4): 415-422



Yields increased in tomatoes (cv. Ace 55 VF) growing in soil low in N (<20 p.p.m.), P (2-5 p.p.m.) and K (47-110 p.p.m.), when fertilized with N up to 180 kg/ha and P2O5 up to 90 kg/ha. There was no response to K2O application. At the highest yield (47.5 t/ha), N and P extraction rates were 110 and 20 kg/ha, respectively. N application increased the rates of P, K, Ca and Mg extraction; P absorption was more related to N application than to P2O5 application.
